Configuration and switch management
Optivity network management software consists of views, most of which are maps that illustrate the interconnections between the segments, rings, and nodes of your network. The views allow you to analyze network performance and fault conditions on the individual segments and specific areas in your network. They can also alert you when a problem has occurred in a specific location. For further information about Optivity, contact your Nortel Networks sales representative

Untagged member-a port that has been configured as an untagged member of a specific VLAN. When an untagged frame exits the switch through an untagged member port, the frame header remains unchanged. When a tagged frame exits the switch through an untagged member port, the tag is stripped and the tagged frame is changed to an untagged frame
