docsDevSTPControl
Module: DOCS-CABLE-DEVICE-MIB
OID (symbolic): DOCS-CABLE-DEVICE-MIB::docsDevSTPControl
OID (numeric): 1.3.6.1.2.1.69.1.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object controls operation of the spanning tree protocol (as distinguished from transparent bridging).
If set to stEnabled(1), then the spanning tree protocol is enabled, subject to bridging constraints.
If noStFilterBpdu(2), then spanning tree is not active, and Bridge PDUs received are discarded.
If noStPassBpdu(3), then spanning tree is not active, and Bridge PDUs are transparently forwarded.
Note that a device need not implement all of these options, but that noStFilterBpdu(2) is required.
What is docsDevSTPControl?
Controls whether the device runs the spanning tree protocol: stEnabled turns STP on, noStFilterBpdu disables STP and silently drops received BPDUs (the required minimum behavior), and noStPassBpdu disables STP but transparently forwards BPDUs through. An admin sets this to noStPassBpdu on a cable modem that should let a customer's own switch loop-detection frames pass through untouched.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.69.1.1.5 snmpwalk -v2c -c public <target> DOCS-CABLE-DEVICE-MIB::docsDevSTPControl
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.69.1.1.5.1 snmpget -v2c -c public <target> DOCS-CABLE-DEVICE-MIB::docsDevSTPControl.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.2.1.69.1.1.5.1 i <value>
