Dear all,
I have question about "SNMP IFALIAS" of interface, what is it about?
And how I configure it?

I receive order from HPOV admin;since she wants to see my router via HPOV
And asked me to configure interface alias. The full order is:


i want you to modify the "SNMP IFALIAS" for each interface based on the following schema:

[MG][L2|L3|MPLS][DESTINATION]

{MGL2SDESTINATION, MGL3DESTINATION, MGMPLSDESTINATION}

MG: abbreviation for flag management
L2: Layer 2 connectivity
L3: Layer 3 Connectivity
MPLS: Multiprotocol Label Switching
DESTINATION: Connection Destination


Examples:

Router1 has a layer 3 interface that is connected to Router2
MGL3ROUTER2

Router1 has a layer 2 interface that is connected to a customer Customer1
MGL2CUSTOMER1

Router1 has an MPLS featured interface that is connected to a customer Customer1
MGMPLSCUSTOMER1



Who can help me??

SNMP typically reads the Interface Name (ie. GigabitEthernet0/1) for this information. If you have assigned a description or name to the interface, then it should pick that up as the ifALIAS information instead. VLAN's will have a NAME associated with them when they are created. Interfaces do not. The ifALIAS and ifNAME values should be basically the same if one is used.

Try the following:
ENABLE
CONFIG T
INT G0/0 (or what ever interface you are chaning)
DESCRIPTION MGL3ROUTER2 (example from your post)
EXIT
DO SHOW RUN

Review the change above.

If you have already configured the SNMP- SERVER RO community name, then have your people rescan the router for the change.
