vStpInsDesignatedRoot
Module: ALCATEL-IND1-VLAN-STP-MIB
OID (symbolic): ALCATEL-IND1-VLAN-STP-MIB::vStpInsDesignatedRoot
OID (numeric): 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.1.1.8
Node type: OBJECT-TYPE
Type: BridgeId
Access: read-only
Description: The bridge identifier of the root of the spanning tree as determined by the Spanning Tree Protocol as executed by this instance. This value is used as the Root Identifier parameter in all Configuration Bridge PDUs originated by this node for this instance.
What is vStpInsDesignatedRoot?
This read-only bridge identifier shows which switch is the root of this spanning tree instance, used to compute path costs. Network engineers verify this matches their design intent; if wrong, they adjust bridge priorities on core devices. For example, a production network expects the core switch to be root, not an access switch.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.1.1.8 snmpwalk -v2c -c public <target> ALCATEL-IND1-VLAN-STP-MIB::vStpInsDesignatedRoot
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.1.1.8.1 snmpget -v2c -c public <target> ALCATEL-IND1-VLAN-STP-MIB::vStpInsDesignatedRoot.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> vStpInsDesignatedRoot.1
