Cisco Catalyst 9400 Series
Cisco’s Catalyst 9400 Series introduced this summer do look promising, but it’s still missing a few highlights:
Complete support for redundant supervisors; unavailable according to the release notes dated July 31, 2017
The supervisor module (hardware) supports redundancy, but the software does not. The associated route processor redundancy (RPR) and stateful switchover (SSO) features are also currently not supported. Redundacy[sic] in software will be supported in a later release.
Multigigabit line cardSFP+ line card, and possibly- QSFP/QSFP+ line cards
Visio stencils for chassis, power supplies, supervisor, and line cards
The release notes and data sheets are unclear on the supervisor’s ability to perform as a mobility agent.
So far the Catalyst 4500E Series seems more developed than the new Catalyst 9400 Series.
