Address Resolution Protocol (ARP) is a protocol for mapping an IP address to a device address
recognized in the local network. An address is 32 bits long. In an Ethernet local area network,
however, addresses for attached devices are 48 bits long. (The physical machine address is also
known as a MAC address.) A table, usually called the ARP cache, is used to maintain a correlation
between each MAC address and its corresponding IP address. ARP provides the protocol rules for
making this correlation and providing address conversion in both directions.
To view an Access Point’s ARP statistics:
1. Select the Statistics menu from the Web UI.
2. Select System from the navigation pane (on the left-hand side of the screen). Expand a RF
Domain, select a controller or service platform, and select one of its connected Access Points.
3. Select Network and expand the menu to reveal its submenu items.
4. Select ARP Entries.

The Route Entries screen displays the destination subnet, gateway, and interface for routing
packets to a defined destination. When an existing destination subnet does not meet the needs of
the network, add a new destination subnet, subnet mask and gateway.
IP Address Displays the IP address of the client resolved on behalf of the Access Point.
ARP MAC Address Displays the MAC address corresponding to the IP address being resolved.
Type Lists the type of ARP entry.
VLAN Displays the system assigned VLAN ID where an IP address was found.
