tnExtMstpCistPortAutoEdge

Module: TN-XSTP-MIB

OID (symbolic): TN-XSTP-MIB::tnExtMstpCistPortAutoEdge

OID (numeric): 1.3.6.1.4.1.868.2.5.111.2.3.1.2

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-write

Description: Controls whether the bridge should enable automatic edge detection on the bridge port. This allows operEdge to be derived from whether BPDU's are received on the port or not.

What is tnExtMstpCistPortAutoEdge?

Enables automatic Edge-port detection on this bridge port, so operEdge is derived dynamically from whether BPDUs are actually being received rather than a fixed admin setting. Useful on ports where you're not certain in advance whether an end device or another switch will be connected.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.868.2.5.111.2.3.1.2
snmpwalk -v2c -c public <target> TN-XSTP-MIB::tnExtMstpCistPortAutoEdge

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.868.2.5.111.2.3.1.2.1
snmpget -v2c -c public <target> TN-XSTP-MIB::tnExtMstpCistPortAutoEdge.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.868.2.5.111.2.3.1.2.1 s <value>
