Creating a multicircuit tunnel (example)

Enabling persistently disabled ports

It is strongly recommended to disable ports while they are being configured to prevent unwanted

fabric merges.

1. Connect to the switch and log in using an account assigned to the admin role.

2. Enter the portCfgShow command to view ports that are persistently disabled.

3. After identifying the ports, enter the portCfgPersistentEnable command to enable the ports.

4. Enter the portCfgShow command to verify the port is persistently enabled.

Disabling ports with fmsmode enabled

If you enter portCfgPersistentEnable and receive “command not allowed in fmsmode” or

“command not found” messages, fmsmode may be enabled. You cannot use

portCfgPersistentEnable or portCfgPersistentDisable commands with fmsmode enabled. Use

portenable and portdisable commands instead.

You can determine if fmsmode is enabled by using the ficoncupshow fmsmode command.

For more information on using Fabric OS commands, optional arguments, and command output

refer to the Fabric OS Command Reference Manual.

Creating a multicircuit tunnel (example)

This section provides procedures and applicable commands to create a tunnel containing six

circuits between two switches or blades. Figure 13 illustrates an example of these circuits between

two FX8-24 blades inside a DCX chassis.

FIGURE 13 FCIP tunnel example with six circuits

Six circuits per tunnel are configured in the example. Note that you can create a tunnel with six

FCIP circuits for the 7800 switch and ten circuits per 10 GbE port on a FX8-24 blade. You can,

however, create less circuits if you desire. For additional requirements on the number of circuits

allowed per tunnel and port, refer to “FCIP circuits” on page 18. To create multiple circuits, refer to

the following sections of this guide:

• “Configuring a GbE or XGE port IP address” on page 40

• “Configuring an IP route” on page 41
