To display how the switch builds an ARP table and learns MAC addresses for devices on a specific VLAN and associated member ports, use the following command:
show ip-security arp learning {vlan} vlan_nameTo view the ARP table, including permanent and DHCP secured ARP entries, use the following command:
show iparp {ip_address | mac | vlanvlan_name | permanent} {vrvr_name}The following command disables DHCP secured ARP learning on port 1:1 of the VLAN learn:
disable ip-security arp learning learn-from-dhcp vlan learn ports 1:1
This command was first available in ExtremeXOS 11.6.
This command is available on the Summit X450-G2, X460-G2, X670-G2, X770, and ExtremeSwitching X440-G2, X620, X690, X870 series switches.
