Click the PDU and note the following information from the Outbound PDU Layer tab: Destination MAC Address: 00D0:BA8E:741A Source MAC Address. Switch to simulation mode and repeat the ping 10.10.10.2 command. If you want to configure static MAC address on a Cisco switch, then below are the command. Click 172.16.31.5 and open the Command Prompt. To change, use below command- Cisco-SW(config)#mac address-table aging-time ?Ĭisco-SW(config)#mac address-table aging-time 500 ? The easiest way to find your MAC address on Linux is to execute the ifconfig command with the -a option for all.
You can check using “ show mac address-table aging-time” command and change it as per your requirement.

Use the show ip interface brief command to view the endpoint-specific IP addresses on your router. Total Mac Addresses for this criterion: 4 If you want to check mac address for a particular port number, then you can use “ show mac address-table interface ” Cisco-SW#show mac address-table vlan 1 Total Mac Addresses for this criterion: 1 Cisco-SW#show mac address-table address 0050.7966.6800 If you know the specific mac address, then you can use below command to check mac address entry for that address using “ show mac address-table address “. First of all checking the mac address table by using “ show mac address-table“. To manage mac address table, we need to know a couple of commands in Cisco Catalyst switches.
