Deleting an FCIP circuit

You can delete individual FCIP circuits using the portCfg fcipcircuit command with the delete

option. The command syntax is as follows:

portcfg fcipcircuit ve_port delete circuit_id

For full details on syntax and using this command, refer to the Fabric OS Command Reference

Manual.

Virtual Fabrics

The 1GbE ports (7800 switch and FX8-24 blade), 10GbE ports (FX8-24 blade only), and VE_Ports

can be part of any logical switch. They can be moved between any two logical switches unless they

are members of a circuit configuration. In addition, ports do not need to be offline when they are

moved. However, because GbE ports and VE_Ports are independent of each other, both must be

moved in independent steps. You must delete the configuration on VE_Ports and GbE ports before

moving them between logical switches.

As a recommendation and best practice, leave GE and XGE interfaces in the default logical switch

context and do not move them. There is no reason to move them because any context used by the

VE_Port can use an Ethernet interface in the default switch.

For details on creating virtual switches and fabrics on Brocade switches, refer to the Fabric OS

Administrator's Guide.

Brocade 7800 Switch considerations and limitations

Following are considerations and limitations of a 7800 Switch with configured to support virtual

fabrics:

• Although you can create up to four logical switches on a Brocade 7800 switch, a base switch

cannot be created. Therefore you cannot use the logical switches for XISLs.

• Up to two logical switches will support FICON CUP.

• FCR is not supported on a Brocade 7800 switch enabled with logical switches because the

7800 has no base switch to support EX_Ports.

• A Brocade 7800 switch configured with multiple logical switches cannot be downgraded to a

prior release without deleting all of the non-default logical switches and configurations.

Port sharing

In Fabric OS v 7.0 and later, VE_Ports in different logical switches can share a single GbE port

(1GbE or 10GbE) on the default switch.

NOTE

In prior Fabric OS versions, in order to use a GbE port for an FCIP tunnel, that port needed to be in

the same logical switch as the VE_Port for the tunnel.

With GbE port sharing, you can have the following configuration, as an example:

• Default switch has port GbE0
