====== How to map port name from ifTable to a dot1QVLAN ID and Name ======


THe following steps can be used to map an ifIndex to a dot1QVLAN ID. This helps with ISP customers of Trisul who also want to see the VLAN ID in the same table as the interface names.


  - Retrieve the full dot1dBasePortTable (.1.3.6.1.2.1.17.1.4 )  ''snmpwalk .17.1.4'' 
  - Lookup the ifIndex in the column  dot1dBasePortIfIndex (.1.3.6.1.2.1.17.1.4.1.2) and locate the table index dot1dBasePort(.1.3.6.1.2.1.17.1.4.1.1)
  - Retrieve the full  dot1qPortVlanTable(.1.3.6.1.2.1.17.7.1.4.5) ''snmpwalk 17.7.1.4.5''
  - Lookup the dot1dBasePort from step 2 as the index and get the dot1qPvid (.1.3.6.1.2.1.17.7.1.4.5.1.1). 
  - This is the VLANID for the ifIndex 
  - To retrieve the name of the VLAN . get the full .dot1qVlanStaticTable (.1.3.6.1.2.1.17.7.1.4.3)  ''snmpwalk .1.3.6.1.2.1.17.7.1.4.3''
  - Get the dot1qVlanStaticName .1.3.6.1.2.1.17.7.1.4.3.1.1 against the table index.
