Figure 28 shows a configuration with two trunks, each in a different Failover Trigger. Switch 1 is
the primary GbE2c for Server 1 and Server 2. Switch 2 is the primary GbE2c for Server 3 and
Server 4. VLAN Monitor is turned on. STP is turned off.
If all links go down in trigger 1, Switch 1 disables all downlink ports that reside in VLAN 1. If all
links in trigger 2 go down, Switch 1 disables all downlink ports that reside in VLAN 2.
Figure 28 Two Trunks, with Each in a Different Failover Trigger
Figure 29 shows a configuration with two trunks. VLAN Monitor is turned off, so only one Failover
Trigger is configured on each switch. Switch 1 is the primary for Server 1 and Server 2. Switch 2 is
the primary for Server 3 and Server 4. STP is turned off.
If all links in trigger 1 go down, Switch 1 disables all internal links to server blades.
