Use to display information about ARP.
Field descriptions
Address IP address of the entry
Age Time to live for this entry in seconds
Hardware Addr Physical (MAC) address of the entry
Interface Interface-specifier of the entry (for example, fastEthernet6/0 is
an Ethernet interface on slot 6, port 0)
* Indicates that an ARP entry was added because of an arp validate
command, rather than just an arp command.
Example
host1#show arp

Use to display the configured hold-down time allotted after an initial routing
table change for the accumulation and subsequent distribution of a set of routing
table updates to the line modules. The default value is 3 seconds; the range of
values is 0–30 seconds.
A higher hold-down setting can enhance SRP performance; however, a higher
setting can also delay the implementation of routing table changes on the line
modules.
A hold-down timer value of zero (0) distributes an update after each change to
the routing table.
Example
host1#show forwarding-table route-holddown
Hold-down timer value is 3 seconds.
