6500 Series Virtual Switching Supervisor Engine 720 with 10
Gigabit Ethernet uplinks and IPv6 in hardware is an industry first. The new supervisor
engine combines high-density uplinks, system virtualization, and increased throughput
with scalable performance and a rich IP feature set. This supervisor engine is a key
component of the Cisco VSS 1440 Virtual Switching System, enabling high availability,
operational efficiency, and increased bandwidth with a greater ease of deployment.
The Cisco Catalyst 6500 Series Virtual Switching Supervisor Engine 720 with 10 Gigabit Ethernet
uplinks has a new forwarding engine that combines all the capabilities of its predecessor, the
Cisco Catalyst 6500 Series Supervisor Engine 720, with system virtualization and increased
throughput.
The Cisco Virtual Switching Supervisor Engine 720 with 10 Gigabit Ethernet uplinks includes the
following new features:
●
The Cisco VSS 1440 system virtualization technology pools multiple Cisco Catalyst 6500
Series Switches into one virtual switch. This provides several benefits:
Increases operational efficiency by simplifying the network
Scales system bandwidth capacity to 1.4 Tbps by using Multichassis EtherChannel
(MEC)
Boosts nonstop communications by way of interchassis failover and an EtherChannel
mechanism for link recovery
Eases deployment by using existing multilayer switching architecture
●
Two X2-based 10 Gigabit Ethernet uplinks are built into the supervisor engine, saving a slot
in the chassis for additional integrated services or high-density chassis.
●
All Gigabit Ethernet and 10 Gigabit Ethernet uplinks of the Cisco Virtual Switching
Supervisor Engine 720 can be active simultaneously, even for redundant systems (systems
with dual supervisor engines in the chassis).
●
The Cisco Virtual Switching Supervisor Engine 720 with 10 Gigabit Ethernet uplinks has a
new policy feature card (PFC) that increases throughput to 82 Mpps. As a result, the
system throughput increases to 450 Mpps for IPv4 traffic and 225 Mpps for IPv6 traffic.
●
The Cisco Virtual Switching Supervisor Engine 720 offers a deterministic, sub-second
failover. This results in faster switchover to a standby supervisor in a redundant
configuration.
