CISCO CATALYST 6500 SERIES CLASSIC GIGABIT ETHERNET OPTICAL/MIXED MEDIA INTERFACE MODULES
Designed for distribution and core layers and for data-center and Web-hosting applications, Cisco Catalyst 6500 series Classic Gigabit Ethernet
interface modules provide line-rate forwarding with the following operational advantages and characteristics:
•
Backplane connection—Provide a 32 Gbps shared bus connection
•
Slot requirements—Can occupy any slot in any Cisco Catalyst 6500 Series chassis
•
Supervisor engine—Supported by the Supervisor Engine 1A, Supervisor Engine 2, or Supervisor Engine 720
•
Forwarding mode and performance—Uses the central CEF engine located on the supervisor engine to forward packets up to 15 Mpps per
system in the interface module’s base configuration
•
Distributed forwarding upgrade—None; Classic interface modules cannot be upgraded for distributed forwarding
•
Optics—Supports hot-pluggable gigabit interface converters (GBICs)
