NETGEAR 8800 Chassis Switch CLI Manual
ARP requests and replies. By disabling ARP learning and adding a permanent entry or
configuring DHCP secured ARP, you can centrally manage and allocate client IP addresses
and prevent duplicate IP addresses from interrupting network operation.
To manually add a permanent entry to the ARP table, use the following command:
configure iparp add <ip_addr> {vr <vr_name>} <mac>
To configure DHCP secure ARP as a method to add entries to the ARP table, use the
following command:
enable ip-security arp learning learn-from-dhcp vlan <vlan_name_ ports [all | <ports>]
{poll-interval <interval_in_seconds>} {retries <number_of_retries}
Displaying ARP Information
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_name>
To view the ARP table, including permanent and DHCP secured ARP entries, use the
following command:
show iparp {<ip_addre> | <mac> | vlan <vlan_name> | permanent} {vr <vr_name>}
Note:
DHCP secured ARP entries are stored as static entries in the ARP
table.
Example
The following command disables ARP learning on port 1:1 of the VLAN learn:
disable ip-security arp learning learn-from-arp vlan learn ports 1:1
disable ip-security arp learning learn-from-dhcp
disable ip-security arp learning learn-from-dhcp {vlan} <vlan_name> ports [all | <ports>]
Description
Disables DHCP secured ARP learning for the specified VLAN and member ports.
