Port Channel interface

[vsabariraja]

Hi,

What is the purpose of enabling port channel interface using "int port-channel".

Before enabling this port, I can able to ping my destination, but now i can't.

With the following configuration, I can able to ping my destination and can use both the interface for load sharing.

interface FastEthernet0/2

channel-protocol lacp

channel-group 1 mode active

switchport mode trunk

!

interface FastEthernet0/3

channel-protocol lacp

channel-group 1 mode active

switchport mode trunk

These are L2 etherchannels and would need something to route for them. The "int port-channel " is created when the port channel comes online. You're using lacp above which should be negotiating to whatever is connected on the other side.

The port-channel can be converted to l3 by issuing the "no switchport" under each of these interfaces and the adding an ip address under the l3 "int po1" (in your case).

The port channel interface (int pox) is also seen by spanning-tree as a single interface and treats it as a single link when doing calculations.

HTH,
John
