○ For a port channel interface, enter the keywords port-channel then a number.
○ For a VLAN interface, enter the keyword vlan then a number from 1 to 4094.
○ (OPTIONAL) To clear statistics for all VRRP groups configured, enter the keyword vrrp. Enter a number from 1 to 255
as the vrid.
○ (OPTIONAL) To clear unknown source address (SA) drop counters when you configure the MAC learning limit on the
interface, enter the keywords learning-limit.
When you enter this command, confirm that you want Dell EMC Networking OS to clear the interface counters for that
interface.

Discard Counters
The Dell Networking OS discard counters counts the packets or frames which are legitimate but dropped due to lack of
operation of the higher layer protocol. The discard counters do not count the errors such as runts, giants, throttles, CRC,
overrun, underrun, symbol error, etc.
For example, when an OSPF packet is received on a switch which has OSPF disabled, the packet gets dropped due to filter
processor (FP) entry and the discard counter gets incremented. However, the packets that are forwarded to the CPU are
dropped at the interface level and a copy of the packet is forwarded to the CPU. Therefore, the discard counter is increased
when a packet matches an FP entry, irrespective of the action defined in the FP entry to avoid pipeline processing in the
hardware.
