Cisco Catalyst 6500-E and 6807-XL VSS

The Cisco Catalyst 6500-E and 6807-XL chassis with the Supervisor Engine 2T are the premier distribution

layer platforms. Although the validation of the current release of the design includes the Cisco Catalyst 6807-XL

platform in the core, the Catalyst 6500-E platform is highlighted here, with the additional validation testing for

the 6807-XL in the distribution to be completed in the next release. More more information about the 6807-XL

configuration can be referenced in the Core Layer Platforms section.

• Cisco Catalyst 6500 VSS uses Cisco Catalyst 6500 Supervisor Engine 2T, which offers per slot

switching capacity of 80 Gbps in the Cisco Catalyst 6500-E Series chassis and delivers hardware-

enabled scalability and features. This level of performance enables the system to provide 40-gigabit

Ethernet uplinks for core layer connectivity.

• Adding an additional Cisco Catalyst 6500 Supervisor Engine 2T to each chassis in the VSS pair for

a total of four supervisors creates a Quad-Supervisor SSO (VS4O) configuration, offering the ability

to have an in-chassis standby supervisor capability. The in-chassis standby enables Enhanced Fast

Software Upgrades (eFSU) for minimal downtime during software upgrades, along with the ability to

recover from a degraded state of performance upon loss of a supervisor, without human intervention.

• Cisco 6500 Supervisor Engine 2T supports the line cards with Distributed Forwarding Card 4-E

(DFC4-E), including the WS-X6816-10G, WS-X6908-10G, and WS-X6904-40G-2T, which provide

enhanced hardware capabilities. The WS-X6908-10G provides eight 10-Gbps Ethernet ports with

1:1 oversubscription. The WS-X6904-40G-2T provides up to four 40-Gbps Ethernet ports or up to

sixteen 10-Gbps Ethernet ports using modular adapters and can be programmed to run in 2:1 or 1:1

oversubscription mode.

• The Supervisor Engine 2T supports DFC4-A based line cards, including the WS-X6824 and WS-X6848,

to provide gigabit Ethernet ports. The WS-X6724 and WS-X6748 gigabit Ethernet cards are also

supported when installed with CFC or DFC4-A modules.

• The Supervisor Engine 2T-based switch enhances support for Cisco TrustSec (CTS) by providing

MacSec encryption and role-based access control lists (RBACL), and delivers improved control plane

policing to address denial-of-service attacks.

• VSS effectively allows the merging of two physical chassis into a logical entity that can be operated as a

single device. This configuration provides redundant chassis, supervisors, line cards, and power supplies

and can provide the highest density of the product options for Gigabit Ethernet, 10 Gigabit Ethernet, and

40-Gigabit EtherChannel uplinks using Cisco Multi-chassis EtherChannel (MEC).

• Provides Stateful Switch-Over (SSO) to synchronize infrastructure and forwarding state between

chassis, along with Non-Stop Forwarding (NSF) for graceful-restart of L3 routing protocols, in the event

of a chassis failure. Also allows Enhanced Fast Software Upgrades (EFSU) with In-Service Software

Upgrades (ISSU) for minimizing downtime for system upgrades.

• The Cisco Catalyst 6500-E and 6807-XL chassis with the Supervisor Engine 2T are the premier

distribution layer platforms. They allow for high density aggregation of wiring closets connected with

Gigabit Ethernet and 10-Gigabit Ethernet, while providing an advanced feature set and the highest

resiliency of the available platforms.
