If a QoS service-policy is configured on a channelized interface on a PA-MC-T/E1 or PA-MC-T/E3
port adapter, entering the microcode reload global configuration command under heavy traffic
might result in a failure to forward packets for the interface.

If the clear counters EXEC command is entered from a Secure Shell (SSH) connection on a router
with E1/T1 controllers, a “SYS-3-CPUHOG” error message might be exhibited. This condition
occurs when the clear counters command fails on more than one E1/T1 controller with a
“POT1E1-3-MBOXSEND” error.

occurs when the clear counters command fails on more than one E1/T1 controller with a
“POT1E1-3-MBOXSEND” error.
Workaround: Clear each E1/T1 controller individually.

The Cisco 12000 series Internet router will incorrectly increment the input drops counter because of
an accounting issue. This action might not correctly reflect packets dropped because of congestion.
This situation might be seen on all Internet router interfaces, but has no effect on service or
functionality of the interfaces. There is no workaround.
