Using the BayStack 450 10/100/1000 Series Switch

•All trunk members must have the same VLAN configuration before the Trunk Configuration screen’s Trunk Status field can be set to Enabled (see “VLAN Configuration” on page 3-24).

•When an active port is configured in a trunk, the port becomes a trunk member when you set the Trunk Status field to Enabled. The spanning tree parameters for the port then change to reflect the new trunk settings.

•If you change the spanning tree participation of any trunk member to Enabled or Disabled, the spanning tree participation of all members of that trunk changes similarly (see “ Spanning Tree Considerations for MultiLink Trunks” on page 1-72.

•When a trunk is enabled, the trunk spanning tree participation setting takes precedence over that of any trunk member. When a trunk is active, you can change the trunk STP setting from either the Trunk Configuration screen or the Spanning Tree Configuration screen.

•If you change the VLAN settings of any trunk member, the VLAN settings of all members of that trunk change similarly.

•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 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.

•You cannot configure a trunk member as a monitor port (see “Port Mirroring Configuration” on page 3-45).

•Trunks cannot be monitored by a monitor port; however, trunk members can be monitored (see “ Port-Based Mirroring Configuration” on page 1-77).

•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.
