•When you set any trunk member to Disabled (not active) through the Port

Configuration screen or through network management, the trunk member is

removed from the trunk. The trunk member has to be reconfigured to rejoin

the trunk through the Trunk Configuration screen on the CI menus, or anothe r

management system. A screen prompt precedes this action when you are

using CI menus. A trunk member cannot be disabled if there are only two

trunk members on the trunk.

•You cannot configure a trunk member as a monitor port (see Chapter 3).

•Trunks cannot be monitored by a monitor port; however, trunk members can

be monitored (see “Port-based mirroring configuration”).

•All trunk members must have identical IGMP configurations.

•If you change the IGMP snooping configuration for any trunk member, the

IGMP snooping settings for all trunk members change.

How the MultiLink Trunk reacts to losing distributed trunk members

If your MultiLink Trunk (Figure42) spans separate units in a stack configuration

and any of those units (or trunked MDAs) becomes inactive from a loss of power

or unit failure, the unaffected trunk members remain operational.
