Using the Command Line Interface

set ip ip-ppp vccn flush-routes { on | off }

Specifies whether the Cayman 3220-H should flush (delete) entries 
from its routing table when the specified virtual circuit is down and 
those routes are inaccessible. This command is only available when 
address mapping for the specified virtual circuit is turned off.

Your Cayman 3220-H maintains a dynamic Address Resolution 
Protocol (ARP) table to map IP addresses to Ethernet (MAC) 
addresses. Your Cayman 3220-H populates this ARP table 
dynamically, by retrieving IP address/MAC address pairs only when 
it needs them. Optionally, you can define static ARP entries to map 
IP addresses to their corresponding Ethernet MAC addresses. Unlike 
dynamic ARP table entries, static ARP table entries do not time out.

You can configure as many as 16 static ARP table entries for a Cayman 
3220-H. Use the following commands to add static ARP entries to the 
Cayman 3220-H static ARP table:

set ip static-arp ip-address ip_address

Specifies the IP address for the static ARP entry. Enter an IP address 
in the 

 argument in dotted decimal format. The 

 argument cannot be 0.0.0.0.

set ip static-arp hardware-address MAC_address

Specifies the Ethernet hardware address for the static ARP entry. 
Enter an Ethernet hardware address in the 

 argument in 

nn.nn.nn.nn.nn.nn

 (hexadecimal) format.

A static route identifies a manually configured pathway to a remote 
network. Unlike dynamic routes, which are acquired and confirmed 
periodically from other routers, static routes do not time out. 
Consequently, static routes are useful when working with PPP, since 
an intermittent PPP link may make maintenance of dynamic routes 
problematic.
