Interoperability and Performance Planning

This chapter describes the standards supported by the Cisco switches covered in this guide and provides performance specifications for these switches.

Compatible Standards

The Cisco switches described in this guide are designed to interoperate with switches that support the following standards:

•Private Network-to-Network Interface (PNNI) Version 1

•User-Network Interface (UNI) 3.0

•UNI 3.1

•UNI 4.0

•Integrated Local Management Interface (ILMI) 4.0

•ATM Inter-Network Interface (AINI) 1.0

•Interim Inter-Switch Protocol (IISP) 3.0 and 3.1

•Traffic Management (TM) 4.0

Specifications

Table 2-1lists PNNI network specifications for MGX switches and the MGX 8880 Media

Gateway.Table 2-2lists PNNI network specifications for SES equipped BPX switches.

Note The specifications listed in Table 2-1and Table 2-2are recommended or maximum limits that may be constrained by the memory requirements for other features. For example, the switches listed cannot simultaneously support the maximum number of connections, links, and logical interfaces.
