arp log
This command enables the logging of dynamic and static ARP entries in the ARP cache.
The ARP cache contains mappings of switch ports, VLAN IDs, and IP addresses to physical
MAC addresses for hosts.
This command can display the MAC addresses in the ARP log either using the default
hexadecimal notation (HHHH.HHHH.HHHH), or using the IEEE standard hexadecimal
notation (HH-HH-HH-HH-HH-HH).
Use the no variant of this command to disable the logging of dynamic and static ARP
entries in the ARP cache.
Syntax arp log [mac-address-format ieee]
no arp log [mac-address-format ieee]
Default The ARP logging feature is disabled by default.
Mode Global Configuration
Usage You have the option to change how the MAC address is displayed in the ARP log message,
to use the default hexadecimal notation (HHHH.HHHH.HHHH), or the IEEE format
hexadecimal notation (HH-HH-HH-HH-HH-HH) when you apply the mac-address-format
ieee parameter.
Enter the arp log command without the optional mac-address-format ieee parameter
specified for MAC addresses in the ARP log output to use the default hexadecimal
notation (HHHH.HHHH.HHHH).
Enter the arp log mac-address-format ieee command for MAC addresses in the ARP log
output to use the IEEE standard format hexadecimal notation (HH-HH-HH-HH-HH-HH).
Use the no variant of this command (no arp log) without the optional mac-address-
format ieee parameter specified to disable ARP logging on the switch
Use the no variant of this command with the optional mac-address-format ieee
parameter specified (no arp log mac-address-format ieee) to disable IEEE standard
format hexadecimal notation (HH-HH-HH-HH-HH-HH) and revert to the default
hexadecimal notation (HHHH.HHHH.HHHH) for MAC addresses in the ARP log output.
To display ARP log messages use the show log | include ARP_LOG command.
Parameter Description
mac-address-format ieee Display the MAC address in hexadecimal notation
with the standard IEEE format (HH-HH-HH-HH-HH-
HH), instead of displaying the MAC address with the
default hexadecimal format (HHHH.HHHH.HHHH).
