ieee8021MstpCistPortRestrictedRole

Module: IEEE8021-MSTP-MIB

OID (symbolic): IEEE8021-MSTP-MIB::ieee8021MstpCistPortRestrictedRole

OID (numeric): 1.3.111.2.802.1.1.6.1.3.1.12

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-write

Description: The current state of the restrictedRole parameter for the Port. True(1) causes the Port not to be selected as Root Port for the CIST or any MSTI.

What is ieee8021MstpCistPortRestrictedRole?

Set to true(1) to prevent this port from ever becoming the Root Port for the CIST or any MSTI, even if the normal spanning-tree calculation would otherwise select it — useful on an edge-facing uplink you never want carrying core traffic upstream.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.6.1.3.1.12
snmpwalk -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpCistPortRestrictedRole

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.6.1.3.1.12.1
snmpget -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpCistPortRestrictedRole.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.111.2.802.1.1.6.1.3.1.12.1 s <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ieee8021MstpCistPortRestrictedRole.1
