elarp is a tool to display and delete MAC-to-ATM address ARP
cache entries and associated Switch Virtual Circuits (SVCs).
Used in conjunction with the ATM Forum LAN Emulation Client
(LEC).
- show
- The -elan flag will display all LANE ARP
entries for elan elan. If the -mac flag is
used, the ARP entry for MAC address MAC is
displayed. The time to live (TTL) in seconds
for both the connections and address mappings
are displayed. If no flags are given, all
current LANE ARP entries are displayed. If
more than one MAC address is associated with
an ATM address, then all the MAC-to-ATM
address mappings are shown in a single entry.
- delete
- The -all and - elan flags will delete all
dynamic address mappings from the ARP cache
and close all SVCs to all hosts in the cache,
or all hosts on elan elan, respectively. The
-mac flag will delete the single dynamic
address mapping and SVC for MAC.
The unit number entered is the configured adapter unit
number of an ELAN. The unit number displayed is the adapter
unit number of a connection. The connection unit number may
differ from the configured unit number if UNI loadbalancing/failover
is enabled.
In takeover mode, the elarp command only affects the arp
entries of ELANs on the live filer, and in partner mode the
elarp command only affects the arp entries of ELANs on the
failed filer. The unit number in displayed is always the
adapter unit number on the live filer, even in partner mode.
The following examples display an address mapping for a host
on elan my_elan.
