Additional notes

Ifindex Calculation for VLAN:
IfIndex for VLAN is (10000 + vlan id)
E.G If VLAN-ID is 1050, ifIndex is 10000+1050 = 11050.

Ifindex Calculation for MLT:
IfIndex for MLT is (8192 + MLT id)
E.G MLT 1 = index 8193, for MLT 2, 8194, and so on.

To display all ifIndex values on EDM:
EDM -> Configuration -> Administration -> MIB Web Page, enter ifIndex OID name and walk on it.
