Protected link groups
• FastIron WS and Brocade FCX Series devices support protected link groups consisting of Gbps
fiber ports, 10/100/1000 copper ports, and 10/100 ports, or any combination thereof. These
devices do not support protected link groups on 10-GbE ports.
• This feature is supported with tagged and untaggedports.
• This feature is supported with trunk ports.
• The protected link groups feature is not supported with LACP.
• There is no restriction on the properties of ports in a protected link group. For example,
member ports can be in the same VLAN or in different VLANs.
• When two switches are connected together with links in a protected link group, and the ports
connecting the switches together are part of a protected link group, you must configure two
connecting ports (one port on each switch) as active ports of the protected link group. The
following example illustrates this scenario.
The configuration for the above illustration is as follows.
Switch 1
Brocade(config)# protected-link-group 1 e 1/3 e 1/6
Brocade(config)# protected-link-group 1 active-port 1/3
Switch 2
Brocade(config)# protected-link-group 1 e 1/12 e 1/15
Brocade(config)# protected-link-group 1 active-port 1/12
Creating a protected link group and assigning
an active port
Follow the steps given below to create a protected link group.
1. Specify the member ports in the protected link group. Enter a command such as the following.
Brocade(config)#protected-link-group 10 e 1 to 4
2. Optionally specify which port will be the active port for the protected link group. Enter a
command such as the following.
Brocade(config)#protected-link-group 10 active-port 1
Port1/1
Port1/2
Port1/3
Port1/4
