Port Trunking
N o t e
Using more than one media type and/or link speed in a port trunk is not
supported. The console interface allows only links of the same media type
within the same trunk. Similarly, it is recommended that all links in the same
trunk have the same speed. You should also apply these rules when using a
network management application to configure a port trunk.
A configured trunk appears as a single port (labeled Trk1, Trk2...Trk6)
on other configuration screens, such as the Spanning Tree and Port VLAN
Assignment screens. Also, when assigning a port trunk to a VLAN, all ports in
that trunk must be assigned to that same VLAN.
When trunks are used in conjunction with filters and port monitoring, if a
port is removed from the trunk, the filters and port monitoring for that port
are returned to their default configuration settings.
How To Configure the Port Trunk: Use the Ports Configuration screen to
configure trunks.
