Table 23 summarizes the command-line interface (CLI) commands you can use to monitor and troubleshoot aggregated Ethernet, Fast Ethernet, Gigabit Ethernet, and 10-Gigabit Ethernet interfaces. Commands are listed in alphabetical order.
Table 23: Ethernet Interface Operational Mode Commands
Task |
Command |
|---|---|
Clear dynamic VLAN interfaces. |
|
Clear learned MAC addresses from the hardware and MAC database. Static MAC addresses are not cleared. |
|
Clear statistics that are collected for every MAC address, including policer statistics, on a given physical or logical interface. |
|
Clear statistics that are collected for interface sets. |
|
Clear Operation, Administration, and Management (OAM) connectivity fault management (CFM)linktrace database information. |
clear oam ethernet connectivity-fault-management linktrace path-database |
Clear all statistics maintained by CFM. (Routers that support IEEE 802.1ag OAM CFM) In addition, for interfaces that support ITU-T Y.1731 Ethernet frame delay measurement (ETH-DM), also clear any ETH-DM statistics and frame counts for CFM maintenance association end points (MEPs). |
|
Clear Operation, Administration, and Management (OAM) link fault management state information and restart the link discovery process on Ethernet interfaces. |
|
Clear Operation, Administration, and Management (OAM) statistics link fault management statistics for Ethernet interfaces. |
|
Check the reachability of a remote IEEE 802.1ag OAM maintenance association end point (MEP) or maintenance association intermediate point (MIP). |
|
Force LACP link switchover. |
|
Display status information about aggregated Fast Ethernet or Gigabit Ethernet router interfaces. |
|
Display information about IP demultiplexing interfaces using an underlying Ethernet interface. |
|
Display the transceiver temperature, laser bias current, laser output power, receive optical power, and related alarms for 10-Gigabit Ethernet dense wavelength-division multiplexing (DWDM) interfaces. |
|
Display status information about Fast Ethernet interfaces. |
|
Display status information about 10-Gigabit Ethernet router interfaces. |
|
Display information about Gigabit Ethernet or 10-Gigabit Ethernet router interface sets. |
|
Display information about Gigabit Ethernet or 10-Gigabit Ethernet router interface set queues. |
