Static ARP Settings
Your Cayman 2E-W maintains a dynamic Address Resolution Protocol
(ARP) table to map IP addresses to Ethernet (MAC) addresses. Your
Cayman 2E-W 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
2E-W. Use the following commands to add static ARP entries to the
Cayman 2E-W 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
ip_address
argument in dotted decimal format. The
ip_address
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
MAC_address
argument in
nn.nn.nn.nn.nn.nn
(hexadecimal) format.
Static Route Settings
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.
You can configure as many as 16 static IP routes for a Cayman 2E-W.
Use the following commands to maintain static routes to the Cayman
2E-W routing table:
