vStpInsNextBestRootPortNumber

Module: ALCATEL-IND1-VLAN-STP-MIB

OID (symbolic): ALCATEL-IND1-VLAN-STP-MIB::vStpInsNextBestRootPortNumber

OID (numeric): 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.1.1.12

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: The ifindex of the next port which offers the lowest cost path from this bridge to the root bridge for this spanning tree instance. This port will become root port if the actual root port goes down.

What is vStpInsNextBestRootPortNumber?

This read-only field shows the interface index of the backup port that would become root port if the primary root port failed. Network engineers inspect this to ensure redundant paths exist and failover is possible. If this is missing or has a very high cost, the topology lacks sufficient redundancy.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.1.1.12
snmpwalk -v2c -c public <target> ALCATEL-IND1-VLAN-STP-MIB::vStpInsNextBestRootPortNumber

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.1.1.12.1
snmpget -v2c -c public <target> ALCATEL-IND1-VLAN-STP-MIB::vStpInsNextBestRootPortNumber.1
