ARP Table (CCU and EUM)
For each host (EUM or PC) in the system, the ARP (Address Resolution Protocol) Table
displays the following information:
Table 53 ARP Table Entries
The ARP Table is automatically built by the CCU or EUM based on traffic passing between the
Ethernet and Radio ports. This table displays the host IP and MAC addresses. After the CCU
or EUM recovers the destination IP address from an IP packet sent to the router layer, it looks
in the ARP Table to find the destination Ethernet MAC address. If the IP address does not
appear in the ARP Table, the CCU or EUM obtains the MAC address through an ARP request/
reply and adds it to the ARP Table. The only time a host IP address appears in the ARP Table,
is if the host has recently (in the past ten minutes or so) sent or received data. This can be
forced using a ping, Telnet, SNMP request, or by entering:
arp map <aaa.bbb.ccc.ddd>
where <aaa.bbb.ccc.ddd> is the host IP address.
To view the CCU ARP table:

flags
Refer to Routing Table (CCU and EUM) on page 184 for a description of
these flags.
Refcnt
Number of processes currently referencing this ARP entry. If a process
requires a MAC address, it looks it up in the ARP Table. When the ARP
entry is referenced by a process, refcnt will be incremented by one.
When the process is done with the ARP entry, refcnt will be
decremented by one.
Use
Number of times the ARP Table has been accessed for this network
element.
Interface
The type of interface, one of the following:
• esmc0: Ethernet
• rdr1: Radio
• lo0: Loopback
