The MSTP Configuration of

Function Description

The multiple spanning tree protocol (MSTP) applies to the redundant network. MSTP is an improvement of STP and RSTP. MSTP prevents the proliferation and infinite cycling of the packets in the loop network. In addition, MSTP provides multiple redundant paths for VLAN data transmission to achieve the load-sharing purpose. The MA5680T/MA5683T/MA5608T supports MSTP, which is compatible with the STP and RSTP. It supports MSTP loop network that helps meet various networking requirements.

Function

This command is used to set the mCheck variable to force a port to work in Multiple Spanning Tree Protocol (MSTP) mode. When you need to check whether there is any bridge running STP in the network segment connected to the current port, run this command. After you set the mCheck variable manually, the port work in MSTP mode.

NOTE:

This command can be configured only when the bridge works in MSTP mode. If the bridge is set to work in STP mode, this command does not take effect.

Format

stp port frameid/slotid/portid mcheck

Parameters

Parameter	Description	Value
frameid/slotid/portid	Indicates the subrack ID, slot ID, and port ID. Enter a slash (/) between the subrack, slot, and port IDs. Only the Ethernet port is supported. When you need to force a specified port to work in MSTP mode, use this parameter.	Please see Differences Between Shelves.

Modes

Global config mode

Level

Operator level

Usage Guidelines

• If there is the bridge running STP in the network segment connected to the current port, the port mode transits to STP compatible mode.
• When the network is stable, even if the bridge in the network segment which runs STP is disconnected, the related port still works in STP compatible mode. In this case, you can run the this command to force the port to work in MSTP mode. After that, you can check whether the port works in MSTP mode or STP compatible mode based on the type of the received packets.

Example

To set port 0/19/0 to work in MSTP mode, do as follows:

huawei(config)#stp port 
{ frameid/slotid/portid<S><Length 5-18> }:0/19/0
{ cost<K>|disable<K>|edged-port<K>|enable<K>|instance<K>|loop-protection<K>|mche
ck<K>|point-to-point<K>|port-priority<K>|root-protection<K>|transmit-limit<K> }:
mcheck

  Command:
          stp port 0/19/0 mcheck

System Response

• The system does not display any message after the command is executed successfully.

The MSTP Configuration of stp port loop-protection

Function Description

The multiple spanning tree protocol (MSTP) applies to the redundant network. MSTP is an improvement of STP and RSTP. MSTP prevents the proliferation and infinite cycling of the packets in the loop network. In addition, MSTP provides multiple redundant paths for VLAN data transmission to achieve the load-sharing purpose. The MA5680T/MA5683T/MA5608T supports MSTP, which is compatible with the STP and RSTP. It supports MSTP loop network that helps meet various networking requirements.

Function

This command is used to enable or disable the loop protection of an Ethernet port. When you need to enable the loop protection of a port to suppress the formation of loops, run this command. After the loop protection of an Ethernet port is enabled, the device suppresses the formation of loops.

Format

stp port frameid/slotid/portid loop-protection { enable | disable }

Parameters

Parameter	Description	Value
frameid/slotid/portid	Indicates the subrack ID, slot ID, and port ID. Enter a slash (/) between the subrack, slot, and port IDs. When you need to set the state of the Multiple Spanning Tree Protocol (MSTP), use this parameter.	Please see Differences Between Shelves.
enable	Enables the loop protection of a port.	-
disable	Disables the loop protection of a port.	-

Modes

Global config mode

Level

Operator level

Usage Guidelines

• By default, the loop protection of a port is disabled.
• To avoid the switching network loop due to the link congestion or unidirectional link fault, MSTP provides the loop protection function to suppress the formation of such loop.
• The loop protection prevents the root port and blocked port from switching to the forwarding state when ports are aging. Though these two types of ports can be the specified ports when they are aging, yet they keep in the discarding state and cannot perform the processing only after receiving the BPDU (excluding the TCN packet). This prevents the generation of Spanning Tree Protocol (STP) loop caused by link congestion or unidirectional link fault.
• When you configure a port, only one of the loop protection function, root protection function and BPDU protection function takes effect.

Example

To enable the loop protection of port 0/19/0, do as follows:

huawei(config)#stp port
{ frameid/slotid/portid<S><Length 5-18> }:0/19/0
{ cost<K>|disable<K>|edged-port<K>|enable<K>|instance<K>|loop-protection<K>|mche
ck<K>|point-to-point<K>|port-priority<K>|root-protection<K>|transmit-limit<K> }:
loop-protection
{ disable<K>|enable<K> }:enable 

  Command:
          stp port 0/19/0 loop-protection enable

To disable the loop protection of port 0/19/0, do as follows:

huawei(config)#stp port
{ frameid/slotid/portid<S><Length 5-18> }:0/19/0
{ cost<K>|disable<K>|edged-port<K>|enable<K>|instance<K>|loop-protection<K>|mche
ck<K>|point-to-point<K>|port-priority<K>|root-protection<K>|transmit-limit<K> }:
loop-protection
{ disable<K>|enable<K> }:disable

  Command: 
          stp port 0/19/0 loop-protection disable

System Response

• The system does not display any message after the command is executed successfully.

The MSTP Configuration of stp port edged-port?

Function Description

The multiple spanning tree protocol (MSTP) applies to the redundant network. MSTP is an improvement of STP and RSTP. MSTP prevents the proliferation and infinite cycling of the packets in the loop network. In addition, MSTP provides multiple redundant paths for VLAN. The MA5680T/MA5683T/MA5608T supports MSTP, which is compatible with the STP and RSTP. It supports MSTP loop network that helps meet various networking requirements.

Function

This command is used to set the current Ethernet port as an edge port or a non-edge port. When you need to enable a port to transit to the forwarding state rapidly and also ensure the network security, run this command. If a port is directly connected to the terminal, set the port as an edge port and enable the Bridge Protocol Data Unit (BPDU) protection function. After the current Ethernet port is set as an edge port, the device cannot receive the configuration message transmitted from other bridges.

Format

stp port frameid/slotid/portid edged-port { enable | disable }

Parameters

Parameter	Description	Value
frameid/slotid/portid	Indicates the subrack ID, slot ID, and port ID. Enter a slash (/) between the subrack, slot, and port IDs. Only the Ethernet port is supported. When you need to set the specified port, use this parameter.	Please see Differences Between Shelves.
enable	Sets a specified Ethernet port as an edge port. Edge port refers to a port that is not directly connected to any switch or indirectly connected to any switch through the network connected to the port.	-
disable	Sets a specified Ethernet port as a non-edge port.	-

Modes

Global config mode

Level

Operator level

Usage Guidelines

• By default, all ports are non-edged.
• Only the port connected to the terminal can be set as an edge port. The edge port cannot receive the configuration message (BPDU packets) transmitted from other bridges because the edge port is not connected to any other bridge.
• When the BPDU protection function is disabled and the port receives BPDU, the actual running value of the edge port is a non-edge port even if you set the port as an edge port.
• This setting takes effect on all spanning tree instances, that is, when a port is set as an edge port or a non-edge port, the port is set as an edge port or a non-edge port in all spanning tree instances.
• If a port is connected to a terminal instead of to other bridges or a shared network segment, the port is an edge port. The edge port does not import temporary loops when the network topology changes. Thus, if you set a specified port as an edge port, the port can transit from the blocking state to the forwarding state rapidly without any delay.

Example

To set port 0/19/0 as an edge port, do as follows:

huawei(config)#stp port
{ frameid/slotid/portid<S><Length 5-18> }:0/19/0 
{ cost<K>|disable<K>|edged-port<K>|enable<K>|instance<K>|loop-protection<K>|mche
ck<K>|point-to-point<K>|port-priority<K>|root-protection<K>|transmit-limit<K> }:
edged-port  
{ disable<K>|enable<K> }:enable

  Command:
          stp port 0/19/0 edged-port enable

To set port 0/19/0 as a non-edge port, do as follows:

huawei(config)#stp port
{ frameid/slotid/portid<S><Length 5-18> }:0/19/0 
{ cost<K>|disable<K>|edged-port<K>|enable<K>|instance<K>|loop-protection<K>|mche
ck<K>|point-to-point<K>|port-priority<K>|root-protection<K>|transmit-limit<K> }:
edged-port
{ disable<K>|enable<K> }:disable

  Command: 
          stp port 0/19/0 edged-port disable

System Response

• The system does not display any message after the command is executed successfully.

The MSTP Configuration of stp md5-key

Function

The stp md5-key command is used to set the MD5 key for the MD5 encryption algorithm in an MST region. When you need to encrypt the region to ensure the device security, run this command. After the MD5 key for the MD5 encryption algorithm in the region is set, two devices cannot communicate with each other unless their MD5 keys are the same.
The undo stp md5-key command is used to restore the default MD5 key for the MD5 encryption algorithm in the region. The default MD5 key is recommended. After the MD5 key is modified, you can run this command to restore the default MD5 key. After the default MD5 key for the MD5 encryption algorithm in the region is restored, the MD5 key is 0x13AC06A62E47FD51F95D2BA243CD0346.

Format

stp md5-key number
undo stp md5-key

Parameters

Parameter	Description	Value
number	Indicates the encryption parameter. The string must be hexadecimal and in length of multiples of 2.	Character string type, a string of 1-32 characters. Default: 0x13AC06A62E47FD51F95D2BA243CD0346 Recommended value: 0x13AC06A62E47FD51F95D2BA243CD0346.

Modes

Global config mode, OSN 1500, OSN 2500

Level

Operator level

Usage Guidelines

• For the device security, two devices in a same region cannot communicate with each other unless their MD5 keys are the same. Thus, it is recommended to use the default MD5 key in the settings.
• Two devices that belong to a same MST region must meet the following requirements:
  • The MST region names are the same.
  • The revision levels of the MST region are the same.
  • The configuration digest are the same. The configuration digest is calculated by using the MD5 encryption algorithm based on the VLAN mapping table of all configured spanning trees in the MST region and the MD5 key.

Example

To set the MD5 key for the MD5 encryption algorithm in an MST region to 00e0fc042958, do as follows:

huawei(config)#stp md5-key                                                      
{ string<S><Length 1-32> }:00e0fc042958                                                
                                                                                
  Command:                                                                      
          stp md5-key 00e0fc042958

To restore the default MD5 key for the MD5 encryption algorithm in an MST region, do as follows:

huawei(config)#undo stp md5-key   

System Response

• The system does not display any message after the command is executed successfully.

The MSTP Configuration of stp max-hops

Function

The stp max-hops command is used to set the maximum hops for an Multiple Spanning Tree (MST) region. To limit the network scale of the MST region, you need to set maximum hops. After the maximum hops for the MSTP region is set, the configuration message (BPDU packets) is forwarded from the root device of the spanning tree and the hop count in the BPDU packets decreases 1 by each hop from the maximum hops.
The undo stp max-hops command is used to restore the default maximum hops for an MST region. To limit the MST region in the default scale, run this command to restore the default maximum hops. After the default maximum hops for an MST region is restored, the maximum hops of the device is 20.

Format

stp max-hops hop-count
undo stp max-hops

Parameters

Parameter	Description	Value
hop-count	Indicates the maximum hops for the MST region.	Numeral type. Range: 1-40. Default: 20.

Modes

Global config mode, OSN 2500, OSN 7500

Level

Operator level

Usage Guidelines

• The larger the maximum hops for the MST region is, the larger the scale of the MST region is. Only the maximum hops for the MST region which is configured on the root device of the region can limit the scale of the region. The non root bridge in the MST region adopts the maximum hops of the root bridge.
• The configuration message (BPDU packets) is forwarded from the root device of the spanning tree in the MST region. When the BPDU packets is forwarded by a switch each time, the hop count decreases one. The device discards the received BPDU packets whose hop count is 0 to limit the scale of the MST region.
• If the current device becomes the Common and Internal Spanning Tree (CIST) root bridge device in the MST region or MSTI root bridge device, the maximum hop count configured for this bridge device becomes the network diameter of the spanning tree to limit the scale of the spanning tree in the current MST region.

Example

To set the maximum hops for MST region to 10, do as follows:

huawei(config)#stp max-hops                                                     
{ integer<U><1,40> }:10                                                         
                                                                                
  Command:                                                                      
          stp max-hops 10   

To restore the default maximum hops for MST region, do as follows:

huawei(config)#undo stp max-hops

The EPON LLID Management on ont llid

Function Description

This topic provides the commands related to the EPON Logical Link (Identity configuration LLID) configuration. The EPON LLID can be used to identify ONU in the system, and can be designated in ONU discovery process.

Function

The ont llid command is used to configure a DBA profile and stream control profile for the EPON ONT logical link identifier (LLID) in distributed mode. When you need to configure the upstream bandwidth, a DBA profile and stream control profile for the EPON ONT LLID in distributed mode, run this command.
The undo ont llid command is used to unbind a DBA profile and stream control profile from the EPON ONT LLID in distributed mode. When you need to unbind a DBA profile and stream control profile from the EPON ONT LLID in distributed mode, run this command.

Format

ont llid portid ontid llid-list {{ dba-profile-id profile-id | dba-profile-name profile-name } | ont-car { traffic-table-index | traffic-table-name traffic-table-name } }*
undo ont llid portid ontid llid-list { dba-profile | ont-car }*

Parameters

Parameter	Description	Value
portid	Indicates the EPON port ID.	Please see Differences Between Shelves.
ontid	Indicates the ONT number.	Numeral type. Range: varies with the board type.
llid-list	Indicates the ONT LLID list. The ONT LLID list supports "," and "-". For example, the llid-list value 0, 2-3, indicates LLIDs 0, 2, and 3. Currently, LLID only supports 0.	Character string type, a string of 1–13 characters. The LLID is in the numeral type and ranges from 0–0.
dba-profile-id profile-id	Indicates the DBA profile ID. To bind a DBA profile by specifying the profile ID, use this parameter. A DBA profile is used to configure the upstream bandwidth of the ONT.	Numeral type. Range: 1–512.
dba-profile-name profile-name	Indicates the DBA profile name. To bind a DBA profile by specifying the profile name, use this parameter. A DBA profile is used to configure the upstream bandwidth of the ONT.	Character string type, a string of 1–33 characters.
ont-car traffic-table-index	Indicates the traffic control profile ID. To set the CAR value in an ONT line profile, use this parameter. The traffic control profile is used to control downstream traffic of the ONT.	Numeral type. Range: 0–1023.
traffic-table-name traffic-table-name	Indicates the traffic control profile name. To set the CAR value in an ONT line profile, use this parameter. The traffic control profile is used to control downstream traffic of the ONT.	Character string type, a string of 1–32 characters.

Modes

EPON mode, OSN 6800

Level

Operator level

Usage Guidelines

• Run the config command to enter global config mode, and then run the interface epon command to enter EPON mode.
• This command is used to configure a DBA profile and stream profile in distributed mode. This command and the command for configuring a DBA profile and stream control profile in service profile mode are mutually exclusive. If a DBA profile and stream profile have been configured in service profile mode and you need to run this command, run the undo llid command to cancel the default values of the DBA profile and stream control profile in service profile mode first. If this command has been executed and you need to bind the LLID with a DBA profile or CAR profile in service profile mode, run the undo ont llid command in the EPON mode to unbind the DBA profile and stream control profile from the LLID first.
• When a DBA profile is not bound to the LLID in service profile mode or discrete mode, the default bandwidth is assured bandwidth and is 2 M.
• The restrictions of the upstream bandwidth of PON port the ONT related to are as follows:
  • The fixed bandwidth and assured bandwidth of all the TCONT of all the ONTs reated to the PON port must be smaller than, or equal to the allocable bandwidth of the PON port. The added ONT will use bandwdth, and the allocable bandwidth of the PON port will decrease. You can run the display port info(gpon) command to query the maxium allocable bandwidth of the PON port. The queried result is the allacable bandwith minus the ONT fixed bandwidth cost, and the fixed bandwidth and assured bandwidth that have been allocated.
  • The maximum bandwidth configured in the DBA profile the ONT bound to must be smaller than, or equal to the maximum allocable bandwidth of the PON port that the ONT is related to. You can run the display port info(gpon) command about the PON port that has not been bound by an ONT to query the maximum allocable bandwidth of the PON port.

Example

To bind DBA profile 2 and traffic control profile 2 to ONT LLID 0, do as follows:

huawei(config-if-epon-0/3)#ont llid
{ portid<U><0,7> }:0
{ ontid<U><0,63> }:0
{ llid-list<S><Length 1-13> }:0
{ dba-profile-id<K>|dba-profile-name<K>|ont-car<K> }:dba-profile-id
{ profile-id<U><1,512> }:2
{ <cr>|ont-car<K> }:ont-car
{ traffic-table-index<U><0,1023>| traffic-table-name<K> }:2

  Command:
          ont llid 0 0 0 dba-profile-id 2 ont-car 2

To unbind DBA profile 2 and traffic control profile 2 to ONT LLID, do as follows:

huawei(config-if-epon-0/3)#undo ont llid
{ portid<U><0,63> }:0
{ ontid<U><0,63> }:0
{ llid-list<S><Length 1-13> }:0
{ dba-profile<K>|ont-car<K> }:dba-profile
{ <cr>|ont-car<K> }:ont-car

  Command:
          undo ont llid 0 0 0 dba-profile ont-car

System Response

• The system does not display any message after the command is executed successfully.
