Traffic Snapshots; Displaying Accounting Data And Traffic Statistics - Nortel Versalar 15000 Troubleshooting Manual

Managing and Troubleshooting the Versalar Switch Router 15000
Traffic above the CIR has an upper bound, called the burst rate (BR), beyond
which all traffic is preferentially discarded. Thus, the burst rate prevents any one
type of service from consuming bandwidth contracted for other types of services.

Traffic Snapshots

The accounting function is embedded within the Versalar 15000. Snapshots of
traffic counts are taken periodically and stored in local memory. This collection of
snapshots is then used by external accounting applications to determine service
level usage per access port. The data consists of various packet and octet counts.
For each service class, the Versalar 15000 stores counters for inbound traffic;
below CIR, above CIR, and above BR packets and octets. For outgoing traffic,
only total octet and packet counts per service class are kept. The raw data is then
translated into SNMP MIB attributes, as well as data records, and can be
displayed using the BCC
