Gigabit Ethernet Applications and Key Features
Cisco Catalyst 6500 series mixed media/fiber-based gigabit Ethernet interface modules are used in
distribution and core layers, data-center and Metro Ethernet applications. These gigabit Ethernet
interface modules deliver wire-speed switched connectivity and support several switch fabric
connections and traffic forwarding options, these include: Classic, CEF256, dCEF256 and CEF720.
With a range of port densities and modular physical layer interfaces, these modules also offer a
choice of packet buffer depths for traffic shaping, and QoS granularity with varying number of queues
and drop threshold options. These key features are important aspects to in determining best module
for a given network application (Table 1).

Superior Traffic Management and Queuing Characteristics of Catalyst 6500 series Gigabit
Ethernet Modules
The Cisco Catalyst 6500 Series Gigabit Ethernet modules support multiple queues per port for
Quality of Service. Each port supports Weighted Random Early Detection (WRED) for congestion
avoidance within each queue, and Weighted Round Robin (WRR) for scheduling between queues
and a strict priority queue for voice traffic. Additionally, multiple thresholds can be configured to
manage differentiated levels of service.
Ideal for handling mission-critical, bursty, or low latency traffic such as enterprise resource planning
(ERP) or voice applications, these interface modules, including the CEF720-based WS-X6724-SFP,
scale network performance and intelligent services. These modules also feature transmit and receive
packet buffers and a strict priority transmit queue.
Cisco EtherChannel Technology—Increases Link Resiliency and Provides Scalable Bandwidth
Aggregation
The Catalyst 6500 can aggregate up to eight physical Fast Ethernet, Gigabit Ethernet or 10Gigabit
Ethernet links into a single virtual link using Cisco’s Port Aggregation Protocol (PAgP) or IEEE
802.3ad technology. This provides network managers a reliable high-speed solution for the campus
network backbone.
The Cisco Catalyst 6500 Series also supports multimodule channeling technology, providing even
greater resiliency by creating channels across ports on separate modules in the same chassis. As a
result, connectivity is maintained even if one module (and corresponding ports) fails. This is ideal for
deployments requiring scalable, flexible bandwidth within the network. An additional benefit of Cisco
EtherChannel capabilities include automatic recovery and redistribution of loads across remaining
links; easing management; and making the technology transparent to network applications. The
same Cisco EtherChannel technology can be used across Cisco Systems industry-leading 10-
Gigabit Ethernet modules, providing increased aggregation as well as resiliency against link failure.

* Mode-conditioning patch is required. Using an ordinary patch cord with MMF, 1000BASE-LX/LH SFP/GBICs,
and a short link distance (10s of meters) can cause transceiver saturation resulting in an elevated bit error rate
(BER). In addition, when using the LX/LH SFP/GBIC with 62.5 micron diameter MMF, you must install a mode-
conditioning patch cord between the SFP and the MMF cable on both the transmit and receive ends of the link.
The mode-conditioning patch cord is required for link distances greater than 300 m (984 ft).
** 1000BASE-ZX-SFP can reach up to 100 km by using dispersion-shifted SMF or low attenuation SMF; the
distance depends on fiber quality, number of splices and connectors.
For more information refer to Cisco GBICs and SFP datasheets.
