How to view the Mac of a core switch
Now, do a show mac-address command on the core switch or router. (from what I know you can check that by Switch#sh mac-address-table command) I mean say you are on switch1 what command do you use to check swicth1's mac address? 2) Does each switchport interface have a separate mac addresses for each. When performing troubleshooting or maintenance tasks on an enterprise network, it is sometimes necessary to identify the MAC address of particular devices (hosts, other switches, other network devices) that are connected to the network. On smaller networks, this is somewhat simple to achieve. To find the MAC Address on a Cisco switch port, we use the command show mac-address-table. Let's understand the step by step process under different scenarios. Connect to the Switch/Router by using a console cable or a terminal emulator like Putty or Secure CRT. If you are successful it should look something like this.

Disable one MAC address on the core switch
Issue the mac access-list extended ACL_name cmd, add the host MAC (s) or addresses that you want to block. How can I block a dynamically learned MAC address on the switch? I need to block a specific MAC address that has been learned by the switch. 02-15-2025 01:58 AM Befor mac add to table You can use 802. 1x which make SW prevent add mac into table until this mac is authc You cqn use port-secuirty add. Hi, We are using ProCurve 2530s and E3800 as our core switch. What I am wondering is how to block. There is "lockout-mac": HP-2920-48G (config)# lockout-mac help Usage: lockout-mac <MAC-ADDR>. Another option is to enable MAC security and to set the maximum MAC addresses allowed. The following is the example on ES3510MA. Topology: Here's the configuration: Setting "network-access mac-filter" Console (config)#network-access mac-filter 2 mac-address 00-E0-4C-68-01-5A Console. Dynamic DHCP (D-DHCP) is defined and a device can obtain different IP addresses with in the short period lease. I can't use ACL's because of DDHCP.
