Hi everyone!

I´m still trying to fix the problem on monitoring each virtual station on my
frame relay link. I verified the information of the message below, but I
still having problems.. It follows the passage of the file .conf and the
error returned. Thank´s again for any help!

I believe both Cisco and 3Com use the RFC1315 Mib definitions in their
products. The OID strings would then be: = FECNs Received = BECNs Received = Frames Sent = Octets Sent = Frames Received = Octets Received
    x is the snmp interface number
    y is the DLCI number

If you can do a mibwalk of a router, you'll see the "snmp interface number"
associated with a readable description. For example, Serial 0/0 might be
snmp interface number 3 (or whatever). The value is determined by your
router and what interfaces you have defined on your router. No one will be
able to tell you what that value is; you have to find it.

If you do a mibwalk (getnext) on, you will see
those snmp interface numbers. If you do a mibwalk (getnext) on, you will see the DLCI numbers. If you do a
mibwalk (getnext) on, it will tell you which
DLCIs are Invalid (1), Active (2), or InActive (3). Using mrtg to poll
the Active DLCIs is what you are looking for.

I'd suggest using mrtg to chart the Octets Sent & Received, and FECNs &

Hope that helps...
