ARP Cache Stati

The ARP cache buffers MAC addresses and the associated IP addresses (determined with an ARP request). In this dialog box, you can see the mapping that the station has determined and entered into its ARP cache.

The MAC address and the associated IP address are displayed. A resolve counter and an expiry counter are also provided.

Resolve

The resolve counter indicates the time after which the ARP request is repeated if no response was received.

Expiry

If a MAC address was determined for the IP address, the mapping is retained in the ARP cache for a specific length of time (expiry time) and is used for other send jobs. When the Expiry counter expires, the entry is deleted from the ARP cache. If the IP address is needed for a MAC address again later, a new ARP request is sent. This ensures that changes in the network can be detected and reflected by sending new ARP requests.

Adapter

Number of the network adapter used for handling the ARP functions.
