Function Description
Multicast refers to the point-to-multipoint communication between a certain node and all other nodes in the network. The core of the multicast technology is to duplicate the packets at the place nearest to the receiver, thus lowering the multicast traffic on the network.Controllable multicast allows an access device to determine if a user has the authority to watch programs by identifying the user request packets. In this way, the access device controls and forwards the multicast services. The MA5680T/MA5683T/MA5608T provides the IPTV service by using the multicast technology. By using controllable multicast, the access device manages and controls multicast users. This helps to meet the requirements of the carriers for video services provisioning, and to enable the multicast services to be operable and manageable.
Function
This command is used to query the IGMP logs. To obtain the online and offline
logs of the IGMP users, run this command.
Format
display igmp log { port
frameid/slotid/portid [ gemport gemport-id ]
| ip ip-addr vlan vlanid [
sourceip ip-addr ] } { all |
time start-date start-time [end
end-date end-time ] }
display igmp log service-port index { all | time start-date start-time [end end-date end-time ] }
display igmp log all [ verbos ]
display igmp log service-port index { all | time start-date start-time [end end-date end-time ] }
display igmp log all [ verbos ]
Parameters
| Parameter | Description | Value |
|---|---|---|
| port frameid/slotid/portid | Indicates the shelf ID, slot ID, and port ID. Enter a slash (/) between the shelf and slot IDs. To query the log based on the user port, use this parameter. | Please see Differences Between Shelves. |
| service-port index | Indicates the service port ID. | |
| gemport gemport-id | GEM port number. GEM ports of each PON port are numbered in a centralized way. GEM ports 0-127 are reserved for the private use of OMCI and GEM ports 4000-4095 serve as channels for special use. | Numeral type. Range: 128-3999. |
| ip ip-addr |
Indicates the program IP address. To query the logs based on the program IP address, use this parameter. |
IPv4 address format. Dotted decimal notation. |
| vlan vlanid |
Indicates the multicast MVLAN ID. When you need to query the logs based on the program, use this parameter with the ip-addr parameter to specify the program. |
Numeral type. Range: 1-4093. |
| sourceip ip-addr |
Indicates the multicast source IP address. When "IP address + MVLAN
+ Multicast source IP address" is used to identify a multicast program, use this
parameter.
NOTE:
|
IPv4 address format. Dotted decimal notation. |
| all | Indicates all logs of all ports. | - |
| verbos | Indicates the detailed logs. | - |
| time start-date start-time | Indicates the start date and time, with the format of yyyy-mm-dd hh:mm:ss. The system starts to collect statistics of the IGMP logs from the specified time. | - |
| end end-date end-time | Indicates the end date and time, with the format of yyyy-mm-dd hh:mm:ss. This parameter is optional. When you enter this parameter, the system stops collecting statistics of the IGMP logs at the specified time. If you do not enter this parameter, the time range will not be checked. | - |
Modes
Privilege mode, BTV mode, MVLAN mode
Level
Operator level
Usage Guidelines
- Run the config command to enter the global config mode, and then run the btv command to enter the BTV mode.
- Run the config command to enter the global config mode, and then run the multicast-vlan command to enter the MVLAN mode. Or, in the BTV mode, run the multicast-vlan command to enter the MVLAN mode.
- A long IPv6 address may be incompletely displayed. You can run the display igmp log all verbose command to query the detailed information.
- After the DST is set, the output of the query command contains DST information. For detailed about the information, see "Example."
Example
To query all the log records of the IGMP user, do as follows:
huawei#display igmp log all ------------------------------------------------------------------------------ Port Program IP/S VLAN Mode Join time Leave time Cause ------------------------------------------------------------------------------ 0/3/0/1000 238.1.1.2 122 W 2011-06-09 2011-06-09 1 192.168.1.2 11:30:31+08:00 11:38:26+08:00 0/3/1/100 238.1.1.2 122 W 2011-06-09 2011-06-09 1 192.168.1.3 11:29:51+08:00 11:37:57+08:00 ------------------------------------------------------------------------------ Total: 2 Note: P(Mode) indicates preview, W(Mode) indicates watch N(Mode) indicates no authority F(Mode) indicates preview times full outAfter the DST is set. To query all the log records of all IGMP users, do as follows:
huawei#display igmp log all ------------------------------------------------------------------------------ Port Program IP/S VLAN Mode Join time Leave time Cause ------------------------------------------------------------------------------ 0/3/0/1000 238.1.1.2 122 W 2011-06-09 2011-06-09 1 192.168.1.2 11:30:31+08:00 DST 11:38:26+08:00 DST 0/3/1/100 238.1.1.2 122 W 2011-06-09 2011-06-09 1 192.168.1.3 11:29:51+08:00 DST 11:37:57+08:00 DST ------------------------------------------------------------------------------ Total: 2 Note: P(Mode) indicates preview, W(Mode) indicates watch N(Mode) indicates no authority F(Mode) indicates preview times full outAssume that the log record is user. To query all the log records of all IGMP users, do as follows:
