Description

The Catalyst 6816-X is a fixed 2RU backbone switch in the Catalyst 6800 family, built on the 6840-X platform. It is aimed at small and midsize campus backbones that need premium 10G services, and it can also act as an MPLS aggregator or an Instant Access controller, as well as a campus core or distribution aggregation switch.

This LE variant provides 16 native 10G SFP/SFP+ ports with up to 80 Gbps of full duplex switching capacity and up to 60 Mpps of forwarding performance. It uses standard LE table sizes: 128K MAC entries, 256K IPv4 and 128K IPv6 routes, 64K shared ACL entries and 512K NetFlow entries per system. Oversubscription is 2:1 by default and can be configured to 1:1 in performance mode. The chassis takes two hot-swappable 750W AC or DC power supplies in 1+1 redundancy.

Optics support covers SFP-10G-SR, LRM, LR, ER and ZR, DWDM-SFP10G, SFP-H10GB twinax cables up to 10m, and a range of 1G SFPs including GLC-SX-MM, GLC-LH-SM, GLC-ZX-SM and GLC-T. Virtual Switching System (VSS) is supported between 6840-X chassis, and the switch requires Cisco IOS 15.2(2)SY or later.
