ieee8021MstpCistPortRestrictedTcn

Module: IEEE8021-MSTP-MIB

OID (symbolic): IEEE8021-MSTP-MIB::ieee8021MstpCistPortRestrictedTcn

OID (numeric): 1.3.111.2.802.1.1.6.1.3.1.13

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-write

Description: The current state of the restrictedTcn parameter for the Port. True(1) causes the Port not to propagate topology changes to other Ports.

What is ieee8021MstpCistPortRestrictedTcn?

Set to true(1) to stop this port from propagating topology-change notifications to other ports, useful for isolating a chronically flapping edge link so it doesn't repeatedly force MAC table flushes elsewhere in the network.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.6.1.3.1.13
snmpwalk -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpCistPortRestrictedTcn

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.6.1.3.1.13.1
snmpget -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpCistPortRestrictedTcn.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.111.2.802.1.1.6.1.3.1.13.1 s <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ieee8021MstpCistPortRestrictedTcn.1
