Adding and removing ports on a logical switch

Adding and removing ports on a logical switch

This procedure explains how to add and remove ports on logical switches.

All ports in a chassis must be assigned to a logical switch. All ports are initially assigned to the 
default logical switch. 

When you create a logical switch, it has no ports assigned to it. You add ports to a logical switch by 
moving the ports from one logical switch to another. See 

on page 220 for port restrictions.

If you want to remove a port from a logical switch, you cannot just remove it from the logical switch; 
you must move the port to a different logical switch.

When you move a port from one logical switch to another, the port is automatically disabled. Any 
performance monitors that were installed on the port are deleted. If monitors are required in the 
new logical switch, you must manually reinstall them on the port after the move.

If the logical switch to which the port is moved has fabric mode Top Talkers enabled, then if the port 
is an E_Port, fabric mode Top Talker monitors are automatically installed on that port.

NOTE

If you are deploying ICLs in the base switch, then all ports associated with those ICLs must be 
assigned to the base switch. If you are deploying ICLs to connect to default switches (that is, XISL 
use is not allowed), then the ICL ports should be assigned (or left) in the default logical switch. 

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

2. Enter the following command to move ports from one logical switch to another:

lscfg --config fabricID -slot slot [ -port port ] [ -force ] 

The ports are assigned to the logical switch specified by fabricID and are removed from the 
logical switch on which they are currently configured.

If the -port option is omitted, all ports on the specified slot are assigned to the logical switch.

Specify the -force option to execute the command without any user prompts or confirmation.

NOTE

On the Brocade DCX, the lscfg command does not allow you to add ports 48–63 of the FC8-64 
blade to the base switch. These ports are not supported on the base switch. The Brocade 
DCX-4S does not have this limitation.

3. Enter y at the prompt.

The ports are automatically disabled, then removed from their current logical switch and 
assigned to the logical switch specified by fabricID.

Example 

sw0:FID128:admin> lscfg --config 5 -port 18-20
This operation requires that the affected ports be disabled.
