Cisco Catalyst 6500

The Cisco Catalyst 6500 is a chassis switch with a complex buffer architecture that varies significantly by supervisor and line card combination. It deserves its own analysis rather than a single row in the main table.

Key characteristics:

• Multiple supervisor engine options (SUP720, SUP2T, etc.) with very different architectures
• Line cards with per-port and shared buffer configurations
• VoQ is used on some line card/supervisor combinations

For detailed information, refer to Cisco's QoS documentation for the specific line card and supervisor engine combination in use.
