With IPHost Network Monitor you can run simple snmp requests against a Nortel device in your network.
mod Vcs Acc Opt Table
Accounting information is owned by the Vc System; it is stored in the Vc Accounting component, which itself is considered to be a component on the switch. The Accounting Component contains a bit map indicating which of the accounting facilities are to be spooled in the accounting record - for example, bit '0' if set indicates that the accounting facility with facility code H.00 should be spooled if present in the Vc for accounting purposes. The data contained in the Vc Accounting must be identical network wide even though the component can be changed and upgraded on a module by module basis.
