Chapter 13: High Availability 42C4911, January 2007
Figure 13-3 shows a configuration with two trunks. VLAN Monitor is turned off, so only one
Failover Trigger is configured on each switch. GbESM 1 is the primary switch for Server 1 and
Server 2. GbESM 2 is the primary switch for Server 3 and Server 4. STP is turned off.
If all links in trigger 1 go down, GbESM 1 disables all internal links to server blades.
