The new Catalyst 6840-X (released in early 2015) is the smallest device in the 6000 family, yes, it’s the smallest campus switch in the Catalyst 6000 family.
The Cisco Catalyst 6840-X comes in four configurations: 16x10G, 32x10G, 24x10G with two 40G uplinks, and 40x10G with two 40G uplinks.
All switches are Layer 2/3 IPv4/v6 devices with MPLS, VPLS, 256K IPv4 routes, 512K NetFlow flows, large buffers, TrustSec Security Group Tags, MACSec, LISP and support for Catalyst 6800 Instant Access switch clients.
The 40 ports of 10G SFP and SFP+ can be grouped into 10 ports of 40G QSFP for a total of 12 ports of 40G QSFP, Cisco says. Conversely, the two 40G QSFP uplinks can each be broken out into 4x10G SFP/SFP+.
The 6840-X ports can also support GLC-T transceivers for 10/100/1000Mbps over copper.
What does the Cisco 6840-X look like? Let’s get started with the Cisco Catalyst 6840-X Switch, the smallest one in the 6000 family.
