Cisco today released updates to its modular Catalyst 4500 and 6500 switch series to add more capacity, scalability and redundancy.

Architecturally 4500 and 6500 have a fair amount in common (compared to say nexus 9K or 7K) The only real design reason we used VSS/6500 was for Link Aggregation across chassis for hosts.

New Catalyst 4500 E-Series chassis and supervisor promise an easy onramp to 10Gig, while new Catalyst 6500 supervisor and Virtual Switching System remake redundant networking Today Cisco Systems ...

The VSS technology leverages Cisco’s Virtual Switching Supervisor Engine 720, which has integrated 10 Gigabit Ethernet uplinks; it can make two Cisco 6500s look and act like one, thereby ...

IIRC, the 4500-X is 10Gigabit while 3850 is single gig with 10G uplinks. You'll burn a couple of 10G ports if you want to do VSS. We run a couple of 4500Xs and, after a few revs of code, they run ...

We assessed VSS performance with three sets of tests measuring fabric bandwidth and delay, failover times, and unicast/multicast performance across a network backbone.

The enhancements include virtual switching for the Cisco Catalyst 6500 and essentially a refresh of the Catalyst 4500 line. The upgrades are intended to usher those two lines, which are long-in ...
