Configuring Interfaces

Configuring ISL between Two Switches

Note Ensure the FC cable is connected between the ports and do a no-shut on each port.

E-port mode is used when the port functions as one end of an Inter-Switch Link (ISL) setting. When you set the port mode to E, you restrict the port coming up as an E port (trunking or non-trunking, depending on the trunking port mode).

switch# conf t --------> Enter configuration commands, one per line. End with CNTL/Z.

switch(config)# interface fc <Slot No/Port No> switch(config-if)# switchport mode E switch(config-if)# end

Ensure you follow this on both the switches between which you are attempting to bring up the ISL link.

Configuring 10-Gbps FC Mode

The 48-port 8-Gbps Advanced Fibre Channel module (DS-X9248-256K9) and the 32-port 8-Gbps Advanced Fibre Channel module (DS-X9232-256K9)can switch between two speed modes—the 1-, 2-, 4-, 8-Gbps or 10-Gbps. By default, the modules are online in the 1-, 2-, 4-, and 8-Gbps modes when they are loaded for the first time. There are two ways to change the ports to the 10-Gbps speed mode:

Using the 10G-speed mode command, which is the recommended method.

Using the generic speed configuration switchport speed command which has certain constraints. The following conditions apply when the ports in the module can be configured to 10-Gbps speed mode:

The ports in the module can be configured to 10-Gbps speed only when the DS-13SLT-FAB3 module bandwidth is 256-G. Any other combination of fabric modules will not let the ports come up in 10-Gbps.

When in 10-Gbps mode, the ports in the module that are not 10-Gbps capable are disabled and will be in out-of-service state.

The ports function only in full rate mode. They cannot be moved to shared rate mode.

The ports cannot be configured in any other speed.

Ports that are capable of 10-Gbps that are disabled or out-of-service cannot be put back in service using the no out-of-servicecommand. To put these ports back in service, all ports in the module first have to be moved to the out-of-service state. Then they can be brought back to the in service state.

Local switching must be disabled, otherwise, ports cannot be configured in dedicated mode.

Only certain ports on the 48-port and 32-port 8-Gbps Advanced Fibre Channel modules are 10-Gbps capable. When running in 10-Gbps mode, the non-10-Gbps ports cannot be operational. They have to be either in shut state or out-of-service state.
