clear counters c e s Clear the counters used in the show interfaces commands for all VRRP groups, VLANs, and physical interfaces, or selected ones. Syntax clear counters [interface] [vrrp [{[ipv6] vrid | vrf instance}] | learning-limit] Parameters interface vrrp [[ipv6] vrid] vrrp [vrf instance] learning-limit (OPTIONAL) Enter any of the following keywords and slot/port or number to clear counters from a specified interface: • For a 1-Gigabit Ethernet interface, enter the keyword GigabitEthernet followed by the slot/port information. • For a Loopback interface, enter the keyword loopback followed by a number from 0 to 16383. • For a Port Channel interface, enter the keyword port-channel followed by a number: C-Series and S-Series Range: 1-128 E-Series Range: 1 to 32 for EtherScale, 1 to 255 for TeraScale and 1 to 512 for ExaScale. • For the management interface on the RPM, enter the keyword ManagementEthernet followed by slot/port information. The slot range is 0-1, and the port range is 0. • For a SONET interface, enter the keyword sonet followed by the slot/port information. • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet followed by the slot/port information. • For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE followed by the slot/port information. • For a VLAN, enter the keyword vlan followed by a number from 1 to 4094. (OPTIONAL) Enter the keyword vrrp to clear the counters of all VRRP groups. To clear the counters of VRRP groups on all IPv6 interfaces, enter ipv6. To clear the counters of a specified group, enter a vrid number from 1 to 255. (OPTIONAL) E-Series only: Enter the keyword vrrp to clear counters for all VRRP groups. To clear the counters of VRRP groups in a specified VRF instance, enter the name of the instance (32 characters maximum). IPv6 VRRP groups are not supported. (OPTIONAL) Enter the keyword learning-limit to clear unknown source address (SA) drop counters when MAC learning limit is configured on the interface. Note: This option is not supported on the S-Series, as the MAC learning limit is not supported Defaults Without an interface specified, the command clears all interface counters.
