Protected link groups
NOTE
If you do not explicitly configure an active port, the Brocade device automatically assigns one
as the first port in the protected link group to come up.
These commands configure port e1 as the active port and ports e2 – e4 as standby ports. If port 1
goes down, the Brocade device enables the first available standby port, and switches the traffic to
that port. Since the above configuration consists of a statically configured active port, the active
port pre-empts other ports in the protected link group. Refer to “About active ports” on page 691.
Syntax: [no] protected-link-group <group-ID> ethernet <port> to <port>
The <group-ID> parameter specifies the protected link group number. Enter a number from 1 – 32.
Each ethernet <port> to <port> specifies the ports in the protected link group. Specify the port
variable in one of the following formats:
• FWS, FCX, and ICX stackable switches – stack-unit/slotnum/portnum
• FSX 800 and FSX 1600 chassis devices – slotnum/portnum
• ICX devices – slotnum/portnum
• FESX compact switches – portnum
[no] protected-link-group <group-ID> active-port ethernet <port>
The <group-ID> parameter specifies the protected link group number. Enter a number from 1 – 32.
The active-port ethernet <port> defines the active port. Specify the port variable in one of the
following formats:
• FWS, FCX, and ICX stackable switches – stack-unit/slotnum/portnum
• FSX 800 and FSX 1600 chassis devices – slotnum/portnum
• ICX devices – slotnum/portnum
• FESX compact switches – portnum
