enterprises and service providers to offer new Layer 2 through 7 services and network capabilities to increase
revenue and user productivity without the need for major equipment upgrades.
The Cisco Catalyst 6500 Series 10 Gigabit Ethernet modules are designed for deployment in the distribution and
core of the campus and data center for traffic aggregation, or for interbuilding, points of presence (POPs), WAN
edge, and metropolitan area network (MAN) connections. These modules support IEEE 802.3ad link aggregation
and Cisco
®
distributed EtherChannel technology for fault-tolerant connectivity and bandwidth scalability of up to 80
Gbps per EtherChannel connection using any 8 ports in the same chassis. In addition, they support hardware-based
multicast replication, quality of service (QoS), access control lists (ACLs), jumbo frames, and low latency to enable
secure and predictable performance for bandwidth-intensive applications.
Applications
16-port 10 Gigabit Ethernet copper module: Data center access and switch-to-switch connectivity
16-port 10 Gigabit Ethernet fiber module: LAN campus and data center distribution and data center access,
where fanout and port density are important
8-port 10 Gigabit Ethernet fiber module: Data center core and distribution, LAN campus core and distribution,
and service providers
4-port 10 Gigabit Ethernet fiber module: Core, interbuilding connections, POPs, WAN edge, and MAN
connections, where no oversubscription and medium to low 10 Gigabit Ethernet density is required
