The following example shows how to enable Frequency Synchronization on an Ethernet interface: RP/0/ RSP0/CPU0:router# config RP/0/ RSP0/CPU0:router(config)# interface gigabitEthernet 0/5/0/0 RP/0/ RSP0/CPU0:router(config-if)# frequency synchronization RP/0/ RSP0/CPU0:router(config-if-freqsync)# The following example shows how to enable Frequency Synchronization on a SONET controller: RP/0/ RSP0/CPU0:router# config RP/0/ RSP0/CPU0:router(config)# controller sonet 0/4/1/0 RP/0/ RSP0/CPU0:router(config-sonet)# frequency synchronization RP/0/ RSP0/CPU0:router(config-sonet-freqsync)# The following example shows how to enable Frequency Synchronization in global configuration: RP/0/ RSP0/CPU0:router# config RP/0/ RSP0/CPU0:router(config)# frequency synchronization RP/0/ RSP0/CPU0:router(config-freqsync)# commit No carrier-delay information is displayed if carrier-delay has not been configured on an interface. In the case of very small interface state flaps, running the carrier-delay down milliseconds command prevents the routing protocols from experiencing a route flap.Įnter the show interface command to see the current state of the carrier-delay operation for an interface. If the carrier-delay down milliseconds command is configured on a physical link that fails and cannot be recovered, link down detection is increased, and it may take longer for the routing protocols to re-route traffic around the failed link. When you delay the processing of hardware link down notifications, the higher layer routing protocols are unaware of a link until that link is stable. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance. To use this command, you must be in a user group associated with a task group that includes the proper task IDs.

This module provides command line interface (CLI) commands for configuring Ethernet interfaces on the Cisco ASR 9000 Series Router. Show frequency synchronization interfaces Show frequency synchronization configuration-errors Show frequency synchronization clock-interfaces
If you have multiple bridge interfaces and want to narrow down the list to a specific bridge, here is the command.Ethernet Interface Commands on the Cisco ASR 9000 Series RouterĬlear frequency synchronization esmc statisticsĬlear frequency synchronization wait-to-restore This command will print the contents of the mac address table for all bridges. # MAC-ADDRESS VID ON-INTERFACE BRIDGE AGEġ DL EE:8A:XX:XX:XX:2A loopback0 loopback0Ģ D 00:08:XX:XX:XX:A0 ether10 MGMT_br. CLI command to show mac table interface bridge host print Flags: X - disabled, I - invalid, D - dynamic, L - local, E - external And in this scenario, separate mac address tables are maintained. You can actually have a valid configuration that uses both.
The two types of configuration are software switching (using bridge interfaces) and hardware switching. There are actually several commands that you should know, depending on how your router is configured. In addition to using the command line to show the mac address table, this tutorial I will also show you how to search for a specific MAC address and filter the table to show mac addresses learned through a specific port. Here are the commands to show the mac address table on a MikroTik Router.
