Configuration Considerations - H3C S9500E Series Configuration Manual

To address business growth, scale up the network to extend its forwarding capability while protecting the
present investments of the customer. Ease of management and maintenance must also be ensured.

Configuration considerations

Device A is located at the distribution layer of the network. To improve the forwarding capability at
•
this layer, additional devices are needed. In this example, Device B is added.
To offset the risk of IRF fabric partition, configure MAD to detect multi-active collisions. In this
•
example, ARP MAD is adopted, and the ARP MAD packets are transmitted over dual links
connected to Device C. Enable the spanning tree function on the IRF fabric and Device to prevent
loops.
Configuration procedure
Configure Device A
1.
# Set the member ID of Device A to 1, create IRF port 2, and bind it to physical port Ten-GigabitEthernet
3/0/1.
<Sysname> system-view
[Sysname] irf member 1
Info: Member ID change will take effect after the switch reboots and operates in IRF mode.
[Sysname] irf-port 2
[Sysname-irf-port2] port group interface ten-gigabitethernet 3/0/1
[Sysname-irf-port2] quit
# Save the running configuration to the configuration file for next startup.
[Sysname] save
The current configuration will be written to the device. Are you sure? [Y/N]:y
Please input the file name(*.cfg)[flash:/cfa0516.cfg]
(To leave the existing filename unchanged, press the enter key):
flash:/cfa0516.cfg exists, overwrite? [Y/N]:y
Validating file. Please wait.....................................
The current configuration is saved to the active main board successfully.
Configuration is saved to device successfully.
# Change the operating mode of Device A to IRF.
