NOTE: If you bring a FEB offline (or remove it), interfaces on FPCs
connected to the FEB are deleted. When you bring the FEB back online, the
interfaces are restored.
Plan FEB redundancy groups according to your network requirements.
A FEB redundancy group is a named collection of two or more Forwarding Engine
Boards (FEBs) that can improve interface availability. You can design your redundant
FEB configuration to provide backup on a one-to-one basis, or you can provide one
backup for multiple FEBs. Each FEB redundancy group can contain only one primary
FEB.
To create or edit FEB redundancy groups, use the
feb-redundancy group group-name
Change the default assignments of FPCs to FEBs according to your network
requirements. By default, each FPC is assigned to the FEB of the same identifying
number; for example, FPC 1 is assigned to FEB 1.
To assign an FPC to a FEB, use the
hierarchy level. You can also map an FPC to
mapped to any FEB. (When an FPC is configured not to connect to any FEB, interfaces
on that FPC are not created; however, no alarm is triggered.)
To view which FPCs are mapped to which FEBs and the status of each link, enter
