Configuring ARP Cache Entries
You can add and delete entries in the ARP cache. To add or delete static ARP entries, enter
one of the following commands in Configure mode:
Add a static ARP entry.
Clear a static ARP entry.
Configuring Proxy ARP
The IA can be configured for proxy ARP. The IA uses proxy ARP (as defined in
RFC 1027) to help hosts with no knowledge of routing to determine the MAC address of
hosts on other networks or subnets. Through Proxy ARP, the IA will respond to ARP
requests from a host with a ARP reply packet containing the IA MAC address. Proxy ARP
is enabled by default on the IA.
To disable proxy ARP, enter the following command in Configure mode:
Disable Proxy ARP on
an interface.
Configuring DNS Parameters
The IA can be configured to specify DNS servers, which supply name services for DNS
requests. You can specify up to three DNS servers.
To configure DNS servers, enter the following command in Configure mode:
Configure a DNS server.
You can also specify a domain name for the IA. The domain name is used by the IA to
respond to DNS requests.
To configure a domain name, enter the following command in Configure mode:
Configure a domain name.
