NAME

elarp - Displays or manipulates MAC-to-ATM address mappings

SYNOPSIS

elarp show [ -elan elan -mac mac ] [ -unit unit ]

elarp delete -all -elan elan -mac mac [ -unit unit ]

DESCRIPTION

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).

COMMANDS

show

The -elanflag will display all LANE ARP entries for elan elan. If the -macflag 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 -alland -elanflags 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 -macflag 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 connec- tion unit number may differ from the configured unit number if UNI loadbalancing/ failover is enabled.

CLUSTER CONSIDERATIONS

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 displayed is always the adapter unit number on the live filer, even in partner mode.

EXAMPLE

The following examples display an address mapping for a host on elan my_elan.

% elarp show -elan my_elan

0:20:48:10:d:65 at 0x45.000580ffe1000000.f215149c002048100d65.02 ELAN=my_elan state=valid addrTTL=300 vcTTL=1200 unit=1 vpi/vci=0/49
