ieee8021MstpCistPortMacOperational

Module: IEEE8021-MSTP-MIB

OID (symbolic): IEEE8021-MSTP-MIB::ieee8021MstpCistPortMacOperational

OID (numeric): 1.3.111.2.802.1.1.6.1.3.1.11

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-only

Description: In a Bridge that supports the MAC Operational parameter, the current state of the MAC Operational parameter. True(1) indicates the MAC is operational.

What is ieee8021MstpCistPortMacOperational?

True(1) if this port's underlying MAC is currently operational; a false value here typically corresponds to the physical link being down, which forces the CIST port role for this port to reset.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.6.1.3.1.11
snmpwalk -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpCistPortMacOperational

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.6.1.3.1.11.1
snmpget -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpCistPortMacOperational.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ieee8021MstpCistPortMacOperational.1
