through these ports may be disrupted for a short period of time. In addition to the commands for enabling
and disabling trunking, you can also use the following E_Port commands for administering EX_Port Frame
Trunking:
• Use portCfgSpeed and switchCfgSpeed to set speed for a port or switch.
• Display lists of trunks and members of trunks with the trunkShow command.
• Use trunkDebug to list link characteristics for troubleshooting.
• Use the switchShow command to display the trunking information on the EX_Ports.
For details about using these commands, see ”Administering ISL Trunking” on page 129and individual
commands in the Fabric OS Command Reference.
To display EX_Port trunking information:
1. Log in as an admin and connect to the switch.
2. Enter the switchShow command to display trunking information for the EX_Ports.
fcr_switch:admin_06> switchshow
The following is an example of a master EX_Port and a slave EX_Port displayed in
switchShow.

Configuring LSANs and zoning
An LSAN consists of zones in two or more edge or backbone fabrics that contain the same devices. LSANs
essentially provide selective device connectivity between fabrics without forcing you to merge those fabrics.
FC routers provide multiple mechanisms to manage interfabric device connectivity through extensions to
existing switch management interfaces. You can define and manage LSANs using Advanced Zoning or
Fabric Manager.
Use of administrative domains with LSAN zones and FCR
You can create LSAN zones as a physical fabric administrator or as an individual administrative domain
(AD) administrator. The LSAN zone can be part of the root zone database or the AD zone database. FCR
harvests the LSAN zones from all administrative domains. If both edge fabrics have the matching LSAN
zones and both devices are online, FCR triggers a device import. To support legacy applications, WWNs
are reported based on the administrative domain context. As a result, you must not use the network
