• All trunk members must be configured into the same VLAN before the Trunk
Configuration screen's Trunk Status field can be set to Enabled (See "VLAN
Configuration" on page 3-22).
• When an active port is configured in a trunk, the port becomes a trunk member
as soon as the Trunk Status field is set to Enabled. After the Trunk Status field
is set to Enabled, the spanning tree parameters for the port will change to
reflect the new trunk settings.
• If spanning tree participation of any trunk member is changed (enabled or
disabled), the spanning tree participation of all members of that trunk is
changed similarly (see
• When a trunk is enabled, the trunk spanning tree participation setting takes
precedence over that of any trunk member. When a trunk is active, the trunk
STP setting can be changed from either the Trunk Configuration screen or the
Spanning Tree Configuration screen.
• If the VLAN settings of any trunk member are changed, the VLAN settings of
all members of that trunk are changed similarly.
• When any trunk member is set to Disabled (not active) through the Port
Configuration screen or through network management, the trunk member is
removed from the trunk. The removed trunk member has to be reconfigured
through the Trunk Configuration screen to rejoin the trunk. A screen prompt
precedes this action. A trunk member cannot be disabled if there are only two
trunk members on the trunk.
• A trunk member cannot be configured as a monitor port (see "Port Mirroring
Configuration" on page 3-41).
• Trunks cannot be monitored by a monitor port; however, trunk members can
be monitored (see
• All trunk members must have identical IGMP Snooping configurations.
• If the IGMP Snooping configuration for any trunk member is changed, the
IGMP Snooping settings for all trunk members are changed.
