Cisco ISR4351-V/K9 Router

Cisco ISR4351-V/K9 Router is a Cisco router bundle from the ISR 4000 family: 200Mbps-400Mbps system throughput, 3 WAN/LAN ports, 3 SFP ports, multi-Core CPU,2 service module slots, Security, Voice, WAAS, Intelligrnt WAN, OnePK, AVC. A bundle is a chassis supplied with a defined set of cards, licences and sometimes software, ordered as one part number instead of a dozen.

Bundles are usually cheaper than the same parts bought separately, and that is the point of them. The trade-off is that you take the vendor’s view of what belongs together. Where the bundle matches your requirement it is the efficient way to buy; where it does not, you end up paying for something you will not use, or buying an item twice because the bundle’s version was not quite right.

What to check on a bundle specifically. Exactly which licences are included, because security and throughput entitlements are the usual contents and also the usual gap. Whether the memory and flash suit the software release you intend to run. And whether the interface cards included are the ones you actually want, since a bundle built around a card you will not use is worse value than the headline suggests.

What this platform is for. The ISR 4000 is a branch and regional-office router from Cisco’s current Integrated Services line, where throughput is licensed in tiers rather than fixed. Knowing the family’s intended role is usually more useful than the part number when you are working out whether something fits: a chassis built for one job will do another, but rarely well, and the cost of that mismatch tends to show up as throughput or feature limits rather than as an outright failure.

Three questions worth answering before any router purchase, whatever the model. What the throughput requirement actually is with your feature set enabled, rather than the datasheet figure measured without it. Whether the features you need are licensed as well as present, since on most platforms security and performance are separate entitlements. And how many slots or ports you will need in three years, because adding capacity is cheap and replacing a chassis is not.

A point about end-of-life notices on a platform like this, because it causes real confusion. Cisco publishes these per part number, not per family. The ISR 4000 family is not retired, but individual line cards, route processors and software releases within it have their own notices, and some of them have passed. So “is the platform current?” and “is this specific card still supported?” are two different questions with potentially different answers.

That is why we check the exact part number rather than the family before quoting. Send us the code you are looking at and we will tell you where that specific item stands, not where the platform stands.

Send us what the site actually needs and we will tell you whether this bundle fits it or whether the parts bought separately come out better. We would rather do that arithmetic for you than have you find it out afterwards.

Green Code Technologies is a supplier of Cisco, and we supply Huawei and Juniper networking alongside HPE, Dell, Samsung, Netgear, Ubiquiti and Asus. We would rather tell you a part is no longer supported, or that we need to check it, than take an order for something that will not do what you need.
