Clearing Interface Counters
The counters in the show interfaces command are reset by the clear counters command. This command does not clear the
counters any SNMP program captures.
To clear the counters, use the following the command.
• Clear the counters used in the show interface commands for all VRRP groups, VLANs, and physical interfaces or selected ones.
Without an interface specified, the command clears all interface counters.
EXEC Privilege mode
clear counters [interface] [vrrp [vrid] | learning-limit]
(OPTIONAL) Enter the following interface keywords and slot/port or number information:
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port/subport[/subport]
information.
• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
• For a Loopback interface, enter the keyword loopback then a number from 0 to 16383.
• For the Management interface on the stack-unit, enter the keyword ManagementEthernet then the slot/port information.
• 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.
