The New Routers Are Here! Cisco Catalyst 8000 Series
Cisco announced the new Cisco Catalyst 8000 Series
Routers Edge Platforms last week, so lets go over what was announced and what I expect to see in the future.
(Full Disclosure: I received a pre-briefing on this as part of being a Cisco Champion. I received no compensation, monetary or otherwise, to write this article. My viewpoints are my own and not that of Cisco’s marketing department.)
Over the past few years Cisco has released new small office/home office routers (ISR 1100) and a few new higher-end large campus/data center/aggregation routers (ASR 1000) but the mid-performance branch routers have been essentially the same since the introduction of the ISR 4000 series in 2013 & 2014. These routers have performed admirably over the past seven years, surviving the IWAN faux pas, and gaining SD-WAN capabilities from the Viptela acquisition. But there has been a bit of a performance gap between the higher-end 4000s (500Mb to 2Gb) and the non-modular ASR 1000s (5+Gb), especially when you start looking at SD-WAN encrypted throughput and QoS/DPI/Security. The Catalyst 8000 Edge Platforms now has filled that gap (and then some).
The new hotness
- Catalyst 8300 – Intel x86 based 1 & 2RU modular platform. There are currently four models available:
- C8300-1N1S-6T – 1RU, 1 NIM module slot, 1 SM module slot, 1 PIM module slot (for 4G/5G wireless WAN), and 6x 1GbE interfaces – Up to 1.9 Gbps SD-WAN throughput
- C8300-1N1S-4T2X – 1RU, 1 NIM module slot, 1 SM module slot, 1 PIM module slot, and 4x 1GbE interfaces + 2x 10GbE interfaces – Up to 15 Gbps SD-WAN throughput
- C8300-2N2S-6T – 2RU, 2 NIM module slots, 2 SM module slots, 1 PIM module slot, and 6x 1GbE interfaces – Up to 1.9 Gbps SD-WAN throughput
- C8300-2N2S-4T2X – 2RU, 2 NIM module slots, 2 SM module slots, 1 PIM module slot, and 4x 1GbE interfaces + 2x 10GbE interfaces – Up to 18 Gbps SD-WAN throughput
- Catalyst 8500 – Cisco QFP 3.0 ASIC based 1RU fixed platform. The QFP 3.0 is an evolution of the ASIC used in the ASR 1000 line. There are currently two models available:
- C8500-12X – 1RU, with 12x 1/10GbE interfaces – Up to 40 Gbps SD-WAN throughput OR 118 Gbps of standard forwarding throughput
- C8500-12X4QC – 1RU, with 12x 1/10GbE interfaces, 2x 40/100GbE interfaces, and 2x 40GbE interfaces – Up to 68 Gbps SD-WAN throughput OR 197 Gbps of standard forwarding throughput
- Catalyst 8000V – A virtual
routerplatform that is an evolution of both the CSR 1000v and the ISRv network functions virtualization (NFV) offerings. (Note: I still don’t understand why Cisco had both the CSR1kv and the ISRv. Seems like duplicated effort.) Data sheets state that the Cat8kv can be licensed for over 10Gbps of SD-WAN throughput. It will be available on AWS, Azure, and GCP public clouds as well as ESXi and KVM for on-prem.
If you talk to anyone at Cisco, they are very quick to point out that the Catalyst 8000 isn’t just a router, it’s a “platform”. This kinda makes sense when you dig into it. These devices have powerful CPUs (either Intel x86 or custom Cisco QFP) which enable them to do more than route data or voice (yes, UC gurus, the Catalyst 8000 can do that too). They can host containerized functions on board just like the Catalyst 9000 switches and some of the later ISRs. I expect to see the Wireshark container and a Snort IDS/IPS/FW container when they ship. I’m also waiting to see if they announce a ThousandEyes container or integration now that their acquisition has completed. The new switch module for the Catalyst 8300 has the same UADP ASICs as the Catalyst 9300 switches, so basically you have a branch-in-a-box.
Catalyst? I thought those were switches…
Yes, Timmy. Cisco marketing & branding got their way again. Just like they did with the newest generation of Cisco wireless, they have decided to swap the ISR/ASR name for Catalyst. The word on the street is that it is to create a “unified branding” across the enterprise portfolio. I don’t care what it’s called as long as it works.
Didn’t I read about some new Cisco 8000 routers last year?
You sure did Timmy. Cisco has been on a kick over the past few years naming multiple product lines with the same numeric identifier, mostly with 9000 (Nexus 9000, Catalyst 9000, ASR 9000, MDS 9000,…). Now they are starting with the 8s. It might be confusing briefly, but the Cisco 8000 routers are big Service Provider routers that cost the same as a small mansion (depending on your market). The Catalyst 8000s are priced, well, I don’t really know, but I would expect them to be in line with the ISR 4000s and the ASR 1000s.
Do I have to buy a subscription license for this?
Timmy, you will be (probably) unhappy to know that, yes, Cisco is requiring you to buy a subscription license to go along with the hardware. The license is broken up into 3 feature tiers and 4 bandwidth tiers. Cisco has at least simplified the bandwidth licensing so that is tiered instead of 7 or 8 bandwidth values.
So are the ISR 4000s & ASR 1000s going away?
Officially, no. There are no routers being retired with this announcement as the Catalyst 8000s are “complimenting” the ISRs and ASRs. There is a slide and a translation from the Cisco Schweiz Blog that shows that the Cat8300 is a replacement for the ISR 4431 & 4451 while the Cat8500 is a replacement for the ASR 1001-HX & 1002-HX.

I do believe that in addition to the eventual replacement of the ISR 4000s and ASR 1000s, the Catalyst 8000s also set up the end of the classic vEdge platforms. EoL/EoS has already been announced for the vEdge 100/100b/100m/1000 which leaves the vEdge 2000 & 5000, which are easily replaced with the Catalyst 8300/8500.
What do I expect to see in the future
(Note: I have no inside information on any future platforms or devices. These are just my deductions based off of past performance and a couple of public leaks.)
While this is an exciting launch, there are a few things (and numbers) missing. We don’t have any replacements for the ISR 42xx, 43xx, or 4461 routers. Nor do we have a replacement for the modular ASR 1000 routers. If I take a hint from the Catalyst 9000 line, this is what I would predict.
- Catalyst 8200 – A replacement for the lower-end ISR 42xx & 43xx routers (sooner than later)
- Catalyst 8300 – More SKUs to replace the rest of the ISR 43xx & 44xx routers (sooner than later)
- Catalyst 8500 – More SKUs
- Catalyst 8600 – A chassis based solution to replace the modular ASR 1000s (probably at least a couple of years away)
The little insight I have on this is from the publicly accessable CISCO-PRODUCTS-MIB.my and CISCO-ENTITY-VENDORTYPE-OID-MIB.my SNMP MIB files. Here is what I was able to find:
- C8200-1N-4T (A replacement for some of the 4300s?)
- 4xGE, 1 NIM, 1PIM, 8Core, 8G FLASH, 8G DRAM
- (ENTITY line 2018; PRODUCTS line 2645)
- C8200-L-4G (No NIM slot. A replacement for the 4221/4321?)
- Nobelium – AMD, 4xGE, 1PIM, 8Core, 8G FLASH, 8G DRAM
- (ENTITY line 2019)
- C8500L-8G4X (Less interfaces than the other Cat8500s but more than the 8300s. Possible replacement for the 4461?)
- Fugazi, 4x10GE SFP+, 8x1GE SFP, 12Core, 16G FLASH, 16G DRAM
- (ENTITY line 2026; PRODUCTS line 2651)
While I might not be a huge fan of naming everything “Catalyst” or reusing the same numbering scheme on multiple similar products, I am actually looking forward to getting my hands on some of the new Catalyst 8000
routers edge platforms to put them through their paces.
