Problem with ATM/IMA

Hi all,

I have a problem with new ATM service.

All the interfaces are up. But the router can't ping itself, even though that the interface is UP UP.

Any help will be much appreciated. See config below.

Hello Mohammed,

atm interfaces are different then ethernet interfaces when pinging their own ip address.

verify with

sh atm pvc

and try to ping the remote end

pinging the router itself is not an important test here in this scenario.

In an atm interface pinging the interface itself implies that the packet is really sent out the interface to the remote end and received if the remote sends it back.

when you ping an ethernet interface the packet is not sent out the port but the controller answers if the the interface is up/up

Hope to help

Giuseppe

I noticed you have OAM turned off:

oam-pvc manage 0

When that is off the interface will always look up.
