View the port ip Address: (first find the mac address under the Port and then query the IP address through the arp table)

Display mac-address GigabitEthernet 0/0/39

Display arp | include 94de-806b-e6b7

Or directly query the arp table:

Display arp | include 192.168.20.220

When an arp attack is received, clear the arp table:

Reset arp {all | dynamic [ip-address [vpn-instance-name] | interface-type interface-number [ip-address] | static}

For example:

Reset arp interface GigabitEthernet 0/0/22
