vtpVlanIfIndex
Module: CISCO-VTP-MIB
OID (symbolic): CISCO-VTP-MIB::vtpVlanIfIndex
OID (numeric): 1.3.6.1.4.1.9.9.46.1.3.1.1.18
Node type: OBJECT-TYPE
Type: InterfaceIndexOrZero
Access: read-only
Description: The value of the ifIndex corresponding to this VLAN ID. If the VLAN ID does not have its corresponding interface, this object has the value of zero.
What is vtpVlanIfIndex?
This read-only object reports the ifIndex of the interface that corresponds to a given VLAN ID, or zero if that VLAN has no associated interface, such as an SVI, on this device. An administrator uses this to map a VLAN back to its Layer 3 or management interface for further interface-level troubleshooting. For example, a VLAN reporting vtpVlanIfIndex as zero has no corresponding SVI on this switch, so the admin knows any Layer 3 issues for that VLAN must be handled elsewhere.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.46.1.3.1.1.18 snmpwalk -v2c -c public <target> CISCO-VTP-MIB::vtpVlanIfIndex
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.46.1.3.1.1.18.1 snmpget -v2c -c public <target> CISCO-VTP-MIB::vtpVlanIfIndex.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> vtpVlanIfIndex.1
