lsLoopDetectAction

Module: LINKSWITCH-MIB

OID (symbolic): LINKSWITCH-MIB::lsLoopDetectAction

OID (numeric): 1.3.6.1.4.1.43.17.4

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: If a station appears to be on two ports, Address Filter thrashing will occur. Detection of this situation is possible, and this object controls the action to be taken when the situation is detected. Default is shutport. no-action means that no action will be taken, but this means Ethernet and FDDI networks will be flooded. NOTE: control of traps indicating the condition is not affected. DURABLE.

What is lsLoopDetectAction?

Controls what the LinkSwitch does when it detects Address Filter thrashing caused by a station appearing on two ports at once (a loop): shutport(1) (the default) shuts down the first port where the duplicate was detected, shuteths(2) disables all Ethernet ports while leaving FDDI up, shutunit(3) shuts down all media interfaces, and no-action(4) does nothing, which floods both networks. Traps for the condition are still sent regardless of this setting, and the value is DURABLE.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.17.4
snmpwalk -v2c -c public <target> LINKSWITCH-MIB::lsLoopDetectAction

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.43.17.4.1
snmpget -v2c -c public <target> LINKSWITCH-MIB::lsLoopDetectAction.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.43.17.4.1 i <value>
