ARP Information Menu
The Address Resolution Protocol (ARP) is the TCP/IP protocol that resides within the Internet layer. ARP resolves a physical address from an IP address. ARP queries computers on the local network for their physical addresses. ARP also maintains IP-to-physical address pairs in its cache memory.
In any IP communication, the ARP cache is consulted to see if the IP address of the router is present in the ARP cache. Then the corresponding physical address is used to send a packet.
 
[Address Resolution Protocol Menu]
find - Show a single ARP entry by IP address
port - Show ARP entries on a single port
vlan - Show ARP entries on a single VLAN
mgmt - Show ARP entries on for the management port
refpt - Show ARP entries referenced by a single SP
dump - Show all ARP entries
help - Show help on the fields of ARP entries
addr - Show ARP address list
The ARP information includes the IP address and MAC address of each entry, address status flags (see ARP Dump Flag Values), VLAN and port for the address, and port referencing information.

10.203.153.105 C 00:50:56:aa:52:cf
refpt <SP number (1-4)>
 
Displays the ARP entries referenced by a single SP. For a sample output, see /info/l3/arp/refpt Show ARP Entries on Referenced SP.
dump
 
Displays all ARP entries, including:
*IP address and MAC address of each entry
*Address status flag (see the description in the help entry in this table)
*The VLAN and port to which the address belongs
*The ports which have referenced the address (empty, if no port has routed traffic to the IP address shown)
help
 
Displays help on the ARP field entries. For example:
*IP address — IP address of ARP entry
*Flags
P — Permanent ARP entry (not obtained via an ARP request), for example: IP interface and VIP
R — Indirect ARP (cache) entry for IP address reachable via indirect routes (static/dynamic)
4 — Layer 4 IP address (VIP)
u — Unresolved ARP entry. The MAC address has not been learned.
*MAC address — MAC address of the ARP entry
*VLAN — VLAN of this ARP entry
*Port — Physical port where this IP address owner is connected
*Referenced SPs — SPs on which this ARP entry is present
addr
 
Displays the ARP address list: IP address, IP mask, MAC address, and VLAN flags.
