New Behavior
From Cisco IOS XE Release 3.1.0S onwards, if ingress-classification and oversubscription is enabled then
the counter for dropped packets due to oversubscription are displayed in the overrun field in the
show interface
atm slot/subslot/port
command output.
The following example shows the command output displaying the counter for dropped-packets in the
overrun
field:
Router# show interface atm 1/2/0
ATM1/2/0 is up, line protocol is up
Hardware is SPA-1XOC12-ATM-V2, address is 001a.3046.9460 (bia 001a.3046.9460)

Example of the show controllers Command
The following example shows an output of the
show controllers atm
command on a Cisco ASR 1000 Series
Routers with an ATM SPA installed in the second subslot of a SIP that is installed in slot 0:
Router#
