Address Resolution Commands

get-arp-tbl

Shows ARP table. The Address Resolution Protocol (ARP) table
contains information that shows the maping of IP addresses to MAC
addresses and interface numbers.

SYS_console>get-arp-tbl

IfIndex IpAddress MAC Address

SYS_console>

del-arp-entry

SYS_console>del-arp-entry {<IPaddress>|*}

Deletes entries from the ARP table. If an IP address is specified, the
matching arp entry will be deleted. If * is specified, the entire ARP
table will be flushed. This command should be used if the network
topology has physically changed, e.g. if a management station has
been moved from one segment to another, thus changing its
interface number.
