The Supervisor Engine 6L-E delivers 24 Gbps per slot of switching capacity when deployed with the E-Series line cards in a Cisco Catalyst 4500 E-series chassis. You can mix and match classic line cards and E-Series line cards within a Cisco Catalyst 4500 E-series chassis with no performance degradation. When you deploy the Cisco Catalyst Supervisor Engine 6L-E with classic line cards, all of the features except the 24-Gbps per-slot switching capacity are inherited.

The Cisco Catalyst Supervisor Engine 6L-E also provides flexibility and an easy migration path to 10 Gigabit Ethernet uplinks with dual-purpose X2 slots that can accommodate wire-speed 10 Gigabit Ethernet optics or Cisco TwinGig Converter Modules, enabling Gigabit Ethernet SFP optics.
