Configuring Client ARP 
Caching

You can configure the wireless device to maintain an ARP cache for associated 
client devices. Maintaining an ARP cache on the wireless device reduces the 
traffic load on your wireless LAN. ARP caching is disabled by default.

ARP caching on the wireless device reduces the traffic on your wireless LAN by 
stopping ARP requests for client devices at the wireless device. Instead of 
forwarding ARP requests to client devices, the wireless device responds to 
requests on behalf of associated client devices. 

When ARP caching is disabled, the wireless device forwards all ARP requests 
through the radio port to associated clients, and the client responds. When ARP 
caching is enabled, the wireless device responds to ARP requests for associated 
clients and does not forward requests to clients. When the wireless device receives 
an ARP request for an IP address not in the cache, the wireless device drops the 
request and does not forward it. In its beacon, the wireless device includes an 
information element to alert client devices that they can safely ignore broadcast 
messages to increase battery life. 

Optional ARP Caching

If a client device is associated to an access point in not a Cisco device and is not 
passing data, the wireless device does not know the client IP address. If this 
situation occurs frequently on your wireless LAN, you can enable optional ARP 
caching. When ARP caching is optional, the wireless device responds on behalf of 
clients with IP addresses known to the wireless device but forwards out its radio 
port any ARP requests addressed to unknown clients. When the wireless device 
learns the IP addresses for all associated clients, it drops ARP requests not 
directed to its associated clients.

Configuring ARP Caching

Beginning in privileged EXEC mode, follow these steps to configure the wireless 
device to maintain an ARP cache for associated clients:

1.

Enter global configuration mode.

configure terminal

2.

Enable ARP caching on the wireless device. 

•

(Optional) Use the 

optional

 keyword to enable ARP caching only 

for the client devices whose IP addresses are known to the wireless 
device.

dot11 arp-cache [ optional ]

3.

Return to privileged EXEC mode.

end

4.

Verify your entries.
