Huawei S1700 series switch products debut, high performance network to help the construction of small and medium-sized enterprises

A leading telecom solutions provider Huawei in 2013 Ansett letter Partner Conference launched four new type S2700 series enterprise switch products (gigabit network management POE switches S1700-10GF-2P-PWR, S1700-28GFR-4P-PWR, Ethernet network management POE switch S1700-28FR-2T2P-PWR, Gigabit network switch without S1700-24GR). The new products are mainly aim at the small and medium-sized enterprise users, in addition to enhance the functionality and performance, especially optimize the convenient operation , attention by the majority of partners in the field.
With the arrival of the era of Gigabit Ethernet, small and medium-sized enterprise access switch forwarding capability and safety performance is bound to face challenges. Comparison of S1700 and similar products, has a higher packet forwarding, multi-service access ability, good expansibility, QoS (Quality of Service), a powerful guarantee multicast replication capacity and operational reliability, and can be widely applied to small and medium-sized enterprises, Internet cafes, hotels, schools, Ethernet access scene.
In the market of small and medium enterprises, the user for convenient and easy to use attention have different emphasis than the professional market, can provide “fool” operation more vulnerable to small and medium enterprises. This second congress commercial distribution of new S1700 series of enterprise switches display area is Huawei launched a new generation of green energy-saving switch, convenient management and maintenance methods, PC of simple operation, “one-click” button. At the same time provide function of traffic statistics based on the interface, support for IP network fault detection and location technology. In addition, S1700 is an intelligent PoE (Power over Ethernet) function, can provide low power supply to meet the data communication function at the same time, direct power supply for terminal, terminal no longer need wiring problem considering the power system, in the access network at the same time can be achieved for electrical equipment.
In the unified Internet Pavilion in this meeting, the enterprise core switch S9700 series as T bits high performance routing and switching machine during the same period at.

How to Delete a Console Login Password?

After receiving an ICMP Request packet, a switch does not send it to the ICMP protocol stack but directly returns an ICMP Reply message. This process is called fast ICMPM reply. Switches cannot accurately calculate the delay or jitter of ping packets that require high real-time performance. The protocol stack adds the sending and receiving timestamps to ping packets. The packets need to enqueue frequently between the protocol stack and hardware. This task switching cannot ensure real-time performance of timestamps. In versions earlier than V100R006, fast ICMP reply is a common task. When a switch processes a large volume of service traffic, the reply delay is long due to task switching. In V100R006 and later versions, fast ICMP reply is a super task with a high priority. In most cases, the reply delay is about 1 ms. The actual delay depends on the CPU usage and is shorter than 100 ms. NOTE: By default, box switches have fast ICMP reply enabled in all versions.

The default aging time of ARP entries is 20 minutes. You can run the arp expire-time command to change the aging time.
You can also change the number of ARP probes by running the arp detect-times command. The default number of ARP probes is 3.
When the aging time of an ARP entry expires, the device sends a probe packet to the corresponding IP address every 5 seconds. If the device does not receive any response after the specified number of probes, it deletes the ARP entry.
For example, the aging time of ARP entries is set to 60s and the number of ARP probes is set to 6.
After 60s since an ARP entry is generated, the device sends an ARP probe every 5s. If the device does not receive any response after sending six probes, it deletes the ARP entry. Therefore, the actual aging time of the ARP entry is (60 + 6 x 5) = 90s.
NOTE:
For V100R002 version, the S2700/S3700/S5700/S6700 supports the 1/2 probe time and 3/4 probe time. The numbers of probes on the two time points are both 3 and cannot be changed. For example, if the aging time is 20 minutes (1200s) and the number of ARP probes is 6, the SS2700/S3700/S5700/S6700 sends three ARP probes at an interval of 5s after 10 minutes. After 15 minutes, the S2700/S3700/S5700/S6700 also sends three ARP probes at an interval of 5s. After 20 minutes, the S2700/S3700/S5700/S6700 sends six ARP probes at an interval of 5s. If the S2700/S3700/S5700/S6700 does not receive any response, it deletes the ARP entry.

Basic Configuration on the Device at First Login for Huawei Switches

Huawei Switches Basic Configuration:  How to first login the device on console port or mini USB port.
Here, we will describe how to configure the time and date, device name, management IP address, and the user level and authentication mode for Telnet users at first login through the console port or mini USB port. This configuration apply to all the Huawei switches, such as the popular switch: Huawei S5700,S3700, S2700…

Procedure


1 Set the time and date on the device.

Run:
system-view
The system view is displayed.

Run:
clock timezone time-zone-name { add | minus } offset
The time zone is set.

By default, the system uses the Coordinated Universal Time (UTC) time zone.
add: adds the specified time zone offset to the UTC. That is, the sum of the default UTC time zone and offset equals the time zone specified by time-zone-name.
minus: subtracts the specified time zone offset from the UTC. That is, the remainder obtained by subtracting offset from the default UTC time zone equals the time zone specified by time-zone-name.

Run:
quit
Return to the system view.

Run:
clock datetime HH:MM:SS YYYY-MM-DD
The current time and date are set.
If the time zone is not set, the time set using this command is considered as the UTC time. Before setting the current time, you are advised to confirm the current zone and set the correct time zone offset.

Run:
system-view
The system view is displayed.

Run:
clock daylight-saving-time time-zone-name one-year start-time start-date end-time end-date offset
Or clock daylight-saving-time time-zone-name repeating start-time { { first | second | third | fourth | last } weekday month | start-date1 } end-time { { first | second | third | fourth | last } weekday month | end-date1 } offset [ start-year [ end-year ] ]
Daylight saving time (DST) is set.
By default, DST is not configured.

NOTE:
If you configure periodic DST, the combination of the DST start time and end time can be any of the following: date+date, day of the week+day of the week, date+day of the week, and day of the week+date.
When DST is used, you can run the clock timezone time-zone-name { add | minus } offset command to set the time zone. The time zone in the output of the display clock command is, however, the name of the DST time zone. When DST ends, the system displays the original time zone.

2, Set the device name and management IP address.

Run:
sysname host-name
The device name is set.
By default, the device name is HUAWEI.
When the network management tool needs to obtain the network element (NE) name of a device, you can run the sys-netid command to set an NE name for the device.

Run:
interface interface-type interface-number
The interface view is displayed.
In addition to the management interface on the device, you can also assign the management IP address to Layer 3 interfaces such as VLANIF interfaces on the device.

Run:
ip address ip-address { mask | mask-length }
The management IP address is assigned.
NOTE:
The management IP address is used to maintain and manage the device. Configure the IP address and routes based on the network plan to ensure that the routes between the terminal and device are reachable.

3 Set the user level and authentication mode for Telnet users.

Run:
telnet [ ipv6 ] server enable
The Telnet server is enabled.
By default, the Telnet server is disabled.

Run:
user-interface vty first-ui-number [ last-ui-number ]
The VTY user interface view is displayed.

Run:
protocol inbound { all | telnet }
he VTY user interface is configured to support the Telnet protocol.
By default, a VTY user interface supports the SSH protocol.

Run:
user privilege level level
The Telnet user level is set.
By default, users who log in through the VTY user interface can access commands at level 0.

Run:
authentication-mode aaa
The authentication mode for Telnet users is set to AAA authentication.
By default, no authentication mode is configured for the VTY user interface.
NOTE:
The system provides three authentication modes: AAA authentication, password authentication, and non-authentication modes. AAA authentication requires both the user name and password, and is therefore more secure than password authentication. Non-authentication mode is not recommended because it cannot ensure system security. This section describes how to configure AAA authentication..

Run:
aaa
The AAA view is displayed.

Run:
local-user user-name password irreversible-cipher password
The user name and password for login through Telnet are configured.
The value of password can be a plain-text string of 8 to 128 characters or a cipher-text string of 68 characters.
A too simple password may cause a potential security risk. To enhance the security strength, the password entered in plain text must contain at least two of the following: uppercase letters, lowercase letters, digits, and special characters. In addition, the password cannot be the same as the user name or the mirror user name.

Run:
local-user user-name service-type telnet
The login mode is set to Telnet.

4, Save the configuration.

After basic configuration is complete, you are advised to save the configuration. If the configuration is lost, the connection and configuration for the first login must be performed again.

Run:
return
Return to the user view.

Run:
save
The configuration is saved.
