Nexus 9636 line cards

Introduced December 2016

Broadcom Jericho is here. Two cards - C-R has QSFP28 ports while Q-R has 40 Gb/s QSFP ports. The cards go into one of the 950x chassis, but require their own crossbar cards. After some paid teeth knashing from Nick Lippis in 2013 about how custom ASICs are better than merchant silicon, well, here we are with a merchant based design.

The 100 Gb/s line card has six Jericho ASICs while the 40 G/s version has 3. Like its Jericho brothers, queuing is on the input side of the switch fabric. This is a VoQ design. Cisco has produced a white paper
