Configuring Ethernet Ports

LFP Application Example

This section provides an example of using LFP in a layer 2 network configuration, as shown in the
following sample topology:
Access
In this example:
•
When interfaces 2/1 and 3/1 on OS-1 are down, the access switch will keep interface 1/1 as active and
traffic will still be forwarded to OS-1 even though it has no network connectivity.
•
To allow the switch to use the standby interface the link on OS-1 would need to be disabled so that
interface 1/1 on the access switch leaves the LACP group.
