The N8000 and Cisco switch 802.3ad interconnection configuration method

Publication Date:  2012-11-27 Views:  143 Downloads:  0

Issue Description

While the N8000 takes the 802.3ad (i.e. bond mode=4) to make port binding and improve the bandwidth, the corresponding switch port also needs to initiate the 802.3ad protocol, then we take the Cisco 6509 switch as an example, and illustrate the Cisco switch 802.3ad configuration method.

Alarm Information


Handling Process

The detail configurations are as followed:
Step 1. C6509#conf t --------------------------------enter in the switch’s configuration mode
Step 2. C6509(config)#interface port-channel 1  --------------create the “port-channel” virtual interface, the number “1” denotes the interface ID, Cisco 6509 supports the maximum of 256 virtual interface.
Step 3. C6509(config)#interface gigabitEthernet 1/25     --------------enter in the switch port connecting with the N8000 and using the 802.3ad protocol.
Step 4. C6509(config-if)#channel-group 1 mode active   -----------------start the LACP protocol compulsively.
Remarks: If there are multiple ports need binding, we should implement the step 3 and step 4 repeatedly.
Step 5. C6509(config-if)#end ----------------------------------exit and enter in the switch’s privilege mode.
Step 6. C6509#show run -----------------------------view the configuration information via the “show run” command.
Step 7. C6509#show interfaces etherchannel   ---------------view the work status of the 802.3ad between the switch port and the interconnected N8000 network card.
Step 8. C6509#write    -----------------------------through the “write” command to save the configuration.

Root Cause

The actualization of the 802.3ad protocol is the LACP protocol, and Cisco takes the Ether Channel to actualize LACP.
