Dynamic Counters
By default, counting is enabled for IPFLOW, IPACL, L2ACL, L2FIB.
For the remaining applications, the system automatically turns on counting when you enable the application, and is turned off when you
disable the application.
NOTE: If you enable more than four counter-dependent applications on a port pipe, there is an impact on line rate
performance.
The following counter-dependent applications are supported:
• Egress VLAN
• Ingress VLAN
• Next Hop 2
• Next Hop 1
• Egress ACLs
• ILM
• IP FLOW
• IP ACL
• IP FIB
• L2 ACL
• L2 FIB
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 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.
• For a port extender (PE) Gigabit Ethernet interface, enter the keyword peGigE then the pe-id / stack-unit / port-id
where pe-id is a port-extender ID number from 0 to 255; unit-number is a PE stack-unit number from 0 to 7; port-id is a port
number from 1 to 48.
• For a port extender 10-Gigabit Ethernet interface, enter the keyword peTenGigE then the pe-id / stack-unit / port-id
information. The pe-id range is from 0 to 255; the stack-unit unit-number range is from 0 to 7; and the port-id range is 25 to 28 or
49 to 52 depending on the PE.
• (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.
