etsysMstpPortExtnLoopProtectBlocking

Module: ENTERASYS-MSTP-MIB

OID (symbolic): ENTERASYS-MSTP-MIB::etsysMstpPortExtnLoopProtectBlocking

OID (numeric): 1.3.6.1.4.1.5624.1.2.28.1.4.4.1.3

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-write

Description: The state of this port on this MSTI with respect to the Loop Protect feature.

true(1) - this port is being held in the blocking state by the Loop Protect feature.

false(2) - this port is not being held in the blocking state by the Loop Protect feature.

When this object has a value of true(1) setting its value to false(2) will cause the Loop Protect feature to no longer hold the port in the blocking state.

All other set operations on this object are undefined and MUST NOT have any effect.

What is etsysMstpPortExtnLoopProtectBlocking?

Shows whether Loop Protect is actively holding this port in the blocking state (true); an admin can clear a stuck block by setting this back to false once the underlying issue is resolved, but setting it to true has no defined effect.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5624.1.2.28.1.4.4.1.3
snmpwalk -v2c -c public <target> ENTERASYS-MSTP-MIB::etsysMstpPortExtnLoopProtectBlocking

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.5624.1.2.28.1.4.4.1.3.1
snmpget -v2c -c public <target> ENTERASYS-MSTP-MIB::etsysMstpPortExtnLoopProtectBlocking.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.5624.1.2.28.1.4.4.1.3.1 s <value>
