sprotoTrunking

Module: CTATX-MIB

OID (symbolic): CTATX-MIB::sprotoTrunking

OID (numeric): 1.3.6.1.4.1.97.3.17.1.1.20

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Specifies whether SMC's trunking protocol (an extension to the standard Spanning Tree) is to be used over this port.

What is sprotoTrunking?

This read-write enumerated INTEGER specifies whether SMC's proprietary trunking protocol, an extension to standard Spanning Tree, is used over this port. An admin enables this when linking multiple SMC-compatible bridges together in a trunked topology that relies on this vendor extension. Enabling sprotoTrunking would be necessary when connecting this port to another SMC device configured to use the same proprietary trunking extension.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.97.3.17.1.1.20
snmpwalk -v2c -c public <target> CTATX-MIB::sprotoTrunking

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.97.3.17.1.1.20.1
snmpget -v2c -c public <target> CTATX-MIB::sprotoTrunking.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.97.3.17.1.1.20.1 i <value>

SNMPv3 example:

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