VSF split

A VSF split can occur due to a VSF link failure where all ports in the VSF link go down or any member is power-

cycled or crashes in the chain topology. This failure results in independent VSF fabric fragment each having its

own Commander role. It is recommended to configure a Multiple Active Detection (MAD) mechanism to avoid

duplicate IP addresses, routing issues and traffic forwarding problems when a VSF split occurs.

Figure 107: VSF split

In the preceding figure, after the split, Member 1 will be elected as the new Standby in the previous Commander

fragment. Previous Standby will failover and become Commander. Member 2 will be elected as a new standby to

that fragment. Once the fragment become inactive, all front plane ports except VSF links will be brought down. A

limited set of CLI commands will be available on the inactive fragment.

VSF merge occurs on connecting two different VSF fragments having the same domain-ID through VSF links.

One of the VSF fragments reboots to merge with the other fragment and forms one VSF fabric. Devices merge

only if they have the same domain ID.

NOTE: Only two fragments can be merged at a time.
