Viewing the Address Resolution Protocol Table
The system provides a mechanism for viewing Address Resolution Protocol (ARP) table information to a specific node
or for an entire context. This information can be used to verify that when the system sends an ARP packet, it receives
valid responses from other network nodes. The command has the following syntax:
or for an entire context. This information can be used to verify that when the system sends an ARP packet, it receives
valid responses from other network nodes. The command has the following syntax:
show ip arp [ arp_ip_address ]
arp_ip_address specifies a specific network node for which to display ARP information. The address can be entered in
IPv4 dotted-decimal or IPv6 colon-separated-hexadecimal notation. If this keyword is not specified, all entries within
the context’s ARP table are displayed.

the context’s ARP table are displayed.
Important:
Restarting the VPN Manager removes all interfaces from the kernel which in turn removes all ARP
entries. However, the NPU still retains all of the ARP entries so that there is no traffic disruption. From a user point of
view, show ip arp is broken since this command gathers information from the kernel and not the NPU.
