Understanding Layer 2 Protocol Tunneling

In an SP network, you can use Layer 2 protocol tunneling to enhance the creation of EtherChannels by

emulating a point-to-point network topology. When you enable protocol tunneling (PAgP or LACP) on

the SP switch, remote customer switches receive the PDUs and can negotiate the automatic creation of

EtherChannels.

For example, in

the SP network. When the network tunnels PDUs, switches on the far ends of the network can negotiate

the automatic creation of EtherChannels without needing dedicated lines. See the

Tunneling for EtherChannels" section on page 1-15
