140 Chapter 2 Network configuration
208700-C
• 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 another
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.
• Nortel Networks recommends that you do not enable MAC Address Security
(or BaySecure) on trunk ports.
How the MultiLink Trunk reacts to losing distributed trunk
members
If your MultiLink Trunk ( Figure 42 ) 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.
