This section provides important information about configuring Layer 2 Failover.
Note: Auto Monitor and Manual Monitor are mutually exclusive. They cannot both
be configured on the switch.
 Any specific failover trigger may monitor static trunks only or LACP trunks
only, but not both.
 All external ports in all static or LACP trunks added to any specific failover
trigger must belong to the same VLAN.
A maximum of two LACP keys can be added per trigger.

 When VLAN Monitor is on, the following additional guidelines apply:
All external ports in all static or LACP trunks added to a specific failover

trigger must belong to the same VLAN and have the same PVID.
Different triggers are not permitted to operate on the same VLAN.

Different triggers are not permitted to operate on the same internal port.

For each port in each trunk in a specific failover trigger, the trigger will

monitor the STP state on only the default PVID.
 A Manual Monitor can monitor only external ports.
Any specific failover trigger can monitor external ports only, static trunks only,

or LACP trunks only. The different types cannot be combined in the same
trigger.
 A maximum of two LACP keys can be added per trigger.
 Management ports, FC ports, and stacking ports cannot be monitored.
 Control ports for different triggers must not overlap. Monitor ports may
overlap.
