Figure 14: Traffic Redirected by Fast Failover After SFP Uplink Module
VCP Link Failure
In a ring topology that uses SFP uplink module VCPs, there are four ports per module.
Consecutive pair of ports are automatically configured as backup ports for each other.
For example, if a Virtual Chassis member has an SFP uplink module installed, uplink
module VCPs
ge-0/1/0
and
ge-0/1/1
are automatically configured as the backup port
for the other port in the pair. Similarly, ports
ge-0/1/2
and
ge-0/1/3
are automatically
configured as the backup port for the other port in the pair.
Similarly, in a ring topology that uses XFP uplink module VCPs, there are only two ports
per uplink module. Each port is automatically configured to back up the other port in the
uplink module (for example,
xe-0/1/0
is the backup for
xe-0/1/1
).
Fast Failover in a Virtual Chassis Configuration Using Multiple Ring Topologies
Fast failover is supported in a Virtual Chassis configuration with a multiple-ring topology,
as shown in Figure 15 on page 941.
