Here is an example of searching ARP records for mac address:
show arp | include 10fe.ed58.0555
Viewing ARP over IP, MAC, VLAN:
sh ip arp 192.168.1.22
sh ip arp 01ac:bc11:1100
sh ip arp vlan 100
View the table of mac addresses in the specified VLAN:
show mac address-table vlan 100
Search mac addresses in the table:
show mac-address-table address 20cf.30bd.d1fe
Viewing duplicate mac addresses:
sh mac-address-table duplicate only
View the mac address range of modules in the device:
show module
If you need to remove the MAC or IP from the tables, then:
clear ip arp 192.168.1.5
clear mac-address-table dynamic address 6872.5104.aaaa
clear arp-cache
