InterfacesTo configure egress, port channel, time domain, and UDP, use these interface commands.Topics:• Basic Interface Commands• Port Channel Commands• Enhanced Validation of Interface Ranges• ip http source-interfaceBasic Interface CommandsThe following commands are for Physical, Loopback, and Null interfaces.clear countersClear the counters displayed in the show interfaces commands for all virtual router redundancy protocol (VRRP) groups, virtual local areanetworks (VLANs), and physical interfaces, or selected ones.Syntax clear counters [interface | vrrp {vr-id | ipv6 vr-id} | learning-limit | vlanvlan-id]Parameters interface (OPTIONAL) Enter any of the following keywords and the interface information to clearcounters from a specified interface:• For IPv4 access-group counters, enter the keyword ip.• For IPv6 access-group counters, enter the keyword ipv6.• For a Loopback interface, enter the keyword loopback then a number from 0 to16383.• For MAC access-group counters, enter the keyword mac.• For a Port Channel interface, enter the keywords port-channel then a number.• For the management interface, enter the keyword ManagementEthernet thenslot/port information.• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet thenthe stack/slot/port/subport information.• For a 25-Gigabit Ethernet interface, enter the keyword twentyFiveGigE then thestack/slot/port/subport information.• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the stack/slot/port[/subport] information.• For a 50-Gigabit Ethernet interface, enter the keyword fiftyGigE then the stack/slot/port/subport information.• For a 100-Gigabit Ethernet interface, enter the keyword hundredGigE then thestack/slot/port information.21Interfaces 663
