On the standalone switch #1:

VSS-Sw1(config)#switch virtual domain 101

VSS-Sw1(config-vs-domain)# switch 1

VSS-Sw1(config-vs-domain)# exit

VSS-Sw1(config)#

On the standalone switch #2:

VSS-Sw2(config)#switch virtual domain 101

VSS-Sw2(config-vs-domain)# switch 2

VSS-Sw2(config-vs-domain)# exit

VSS-Sw2(config)#

Step 4: Configure the Virtual Switch Link (VSL).

The VSL is a critical component of the Virtual Switching System. For each physical switch you must select a

unique port-channel number identifying the same VSL. This allows the switch to maintain a separate identity for

the interfaces used when making traffic forwarding decisions. This example uses port-channel number 63 on

switch 1 and port-channel number 64 on switch 2. The PortChannel interface numbers are arbitrary and should

be adapted to best suit your deployment. The chosen values reflect the highest values supported across all

VSS platforms validated in this release. You must configure channel-group mode on for the VSL port channel

because it is an infrastructure link actively managed withing the VSS using Virtual Switch Link Protocol (VSLP).

This example uses the 10-Gigabit Ethernet interfaces on the supervisor of a Cisco Catalyst 6500-E Series switch

for the EtherChannel member ports of the VSL.

On standalone switch #1:

VSS-Sw1(config)#interface port-channel 63

VSS-Sw1(config-if)#switch virtual link 1

VSS-Sw1(config-if)#no shutdown

VSS-Sw1(config)#interface range tengigabit 5/4-5

VSS-Sw1(config-if)#channel-group 63 mode on

VSS-Sw1(config-if)#no shutdown

On standalone switch #2:

VSS-Sw2(config)#interface port-channel 64

VSS-Sw2(config-if)#switch virtual link 2

VSS-Sw2(config-if)#no shutdown

VSS-Sw2(config)#interface range tengigabit 5/4-5

VSS-Sw2(config-if)#channel-group 64 mode on

VSS-Sw2(config-if)#no shutdown

At this point you should be able to see that port-channel 63 and 64 are up, and both links are active on

standalone switch #1 and standalone switch #2, respectively. The switches are not in VSS mode yet.

VSS-Sw1# show etherchannel 63 port

VSS-Sw2# show etherchannel 64 port
