Setting Ve_Ports To Persistently Disabled State; Configuring Vex_Ports; Configuring The Media Type For Gbe Ports 0 And 1 (7800 Switch Only) - Brocade Communications Systems 8 Administrator's Manual

Setting VE_ports to persistently disabled state

VE_Ports used on an FCIP tunnel must be persistently disabled before you can configure FCIP
tunnels. You must change their state from persistently enabled to persistently disabled. Once the
FCIP tunnels have been fully configured on both ends of the tunnel, you can persistently enable the
ports.
1. Enter the portCfgShow command to view ports that are persistently disabled.
2. Enter the portCfgPersistentDisable command to disable any VE_ports that you will use in the

Configuring VEX_ports

If you are going to use a VEX_port in your tunnel configuration, use the portCfgVEXPort command to
configure the port as a VEX_port. VEX_Ports can be used to avoid merging fabrics over distance in
FCIP implementations.
If the fabric is already connected, disable the GbE ports and do not enable them until after you
have configured the VEX_Port. This prevents unintentional merging of the two fabrics.
VEX_Ports are described in detail in the Brocade Fabric OS Administrator's Guide, in the chapter
titled Using the FC-FC Routing Service. Please refer to that publication if you intend to implement a
VEX_Port.
The following example configures a VEX_port, enables admin, and specifies fabric ID 2 and
preferred domain ID 220:

Configuring the media type for GbE ports 0 and 1 (7800 switch only)

Two media types are supported for GbE ports 0 and 1 on the 7800 switch; copper and optical. The
media type must be set for GbE ports 0 and 1 using the portcfggemediatype command. The
command options are as follows:
ge0|ge1
copper|optical
The following example configures port 1 (ge1) in optical mode.
When you enter this command without specifying <media_type>, the current media type for the
specified GbE port is displayed as in the following example.
