ASR5K-FLTR-AIR

ASR5K-FLTR-AIR is a Cisco item for ASR 5000 routing equipment: cisco ASR 5000 Spare Accessory ASR5K-FLTR-AIR.

The catalogue description for this part is brief, and rather than extend it with detail we cannot verify we would rather confirm the specification against the vendor’s own documentation before you order. That is a short job and it avoids the kind of mistake that only shows up on site.

What this platform is for. The ASR 5000 is a mobile packet core platform rather than a general-purpose router, handling the gateway and session functions behind a mobile network. 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.

One date here is worth knowing, because it is close. Cisco announced end of life for the ASR 5000 and 5500 software series in February 2025, with the last day to order on 31 March 2025 and last day of support on 31 July 2027. The hardware platform pages have not been retired in the same breath, which makes the position a little confusing, but the software horizon is the one that governs: a packet core you cannot get software support for is a problem regardless of what the chassis status says.

If you are running this platform, that date is inside most planning horizons and worth putting in front of whoever owns the migration. If you need licences or cards to carry an existing deployment to that point, we can supply them, and we would rather you bought them knowing the date than not.

What we need. The platform, the chassis and the software release this is going into, and what the node has to do. On a replacement, reading the part number off the hardware already installed is the most reliable starting point.

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.
