With IPHost Network Monitor you can run simple snmp requests against a Nortel device in your network.
frNniDlciEirPresent
Frame Relay Nni Dlci Eir Present
This attribute provides the actual Excess Information Rate (EIR) enforced for this DLCI. This number is in units of 800 bits/sec, since that is the internal resolution of Passport rate enforcement. If rateEnforcement is off, then this number does not have meaning. Normally, this attribute matches the provisioned EIR for the DLCI. But when Rate Adaptation is active, then this number will vary to represent the actual Allowed EIR at the moment that this attribute is collected.
