Brocade FastIron Ethernet Switch Platform and Layer 2 Switching Configuration Guide - Manual (Page 146)

Syntax: [no] enable { ethernet stack/slot/port [ to stack/slot/port ] [ ethernet stack/slot/port ] | port-
name name }
Use the ethernet option with the appropriate stack/slot/port variable to specify a Ethernet port within
the LAG that you want to enable.
Use the port-name option with the appropriate name variable to specify a named port within the LAG
that you want to enable.
To enable a port belonging to a keep-alive LAG, you need to configure from the interface level.
Brocade(config-lag-test)#interface e 7/8
Brocade(config-if-e1000-7/8)#enable
Brocade(config-if-e1000-7/8)#
Adding a Port to Currently Deployed LAG
Ports can be added to a currently deployed LAG. Adding a port to a deployed LAG uses the same
procedures as described in
Adding Ports to a LAG or Deleting Ports from a LAG on page 142. When
you add ports to a deployed LAG, the MAC address of the port being added is changed to that of the
primary port of the LAG to which it is being added.
When you add a new secondary port to a currently deployed LAG, the IP directed-broadcast
configuration and all other configuration of the new port should be the same as that of the primary port
of the LAG.
NOTE
In an operational dynamic LAG, adding a port causes port flapping for all LAG ports. This may cause
loss of traffic.
Deleting a Port from a Currently Deployed LAG
Ports can be deleted from a currently deployed LAG. Deleting a port in a currently deployed LAG uses
the same procedures as described in
Adding Ports to a LAG or Deleting Ports from a LAG on page
142. However, when deleting ports from a currently deployed LAG you must consider the following:
• The primary port cannot be removed.
• If removal of a port will result in the trunk threshold value becoming greater than the number of
ports in the LAG, the port deletion will be rejected.
• When you remove a port from a deployed LAG, the port is disabled automatically.
To delete port 1/3/1 which is in the "enabled" state from a currently deployed LAG named "blue", use
the following command:
device(config)# lag blue static
device(config-lag-blue)# no ports ethernet 1/3/1
Syntax: [no] ports ethernet stack/slot/port [ to stack/slot/port ] [ ethernet stack/slot/port ]
NOTE
When a port is deleted from a currently deployed LAG, the MAC address of the port is changed back
to its original value.
