Figure 15: Traffic Redirected by Fast Failover After VCP Link Failures in a
Topology with Multiple Rings
In this scenario, the Virtual Chassis configuration has three rings: two rings that use
dedicated VCPs and one ring that uses SFP uplink module VCPs. Fast failover works
independently on each ring. Each dedicated VCP in a ring is backed up by another
dedicated VCP. Similarly, each SFP uplink module VCP is backed up by another SFP
uplink module VCP. Fast failover does not support a ring topology consisting of a mix of
dedicated VCPs and uplink module VCPs.
Effects of Topology Changes on a Fast Failover Configuration
Once the fast failover feature has been activated, topology changes to the Virtual Chassis
configuration do not affect the fast failover configuration. In the event of a link or switch
failure, fast failover functions normally.
