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.
Gigabit Ethernet Interface Module Switch Fabric and Forwarding Characteristics
The Cisco Catalyst 6500 Classic, CEF256, dCEF256 and CEF720 interface modules provide
Gigabit Ethernet with a choice of speeds and forwarding rates.
