“Love hate relationship”

3.0
Mar 7, 2017
We have a love/hate with both Cisco and their ISR series. We've found the previous gen of HW (18xx) ws actually more powerful from a compute standpoint. Also, if you don't have a cookie cutter break/fix issue then it's almost impossible to get support.

Performance of Cisco ISR G2 Across Market Features

Cisco ISR G2 Likes & Dislikes

Like

IOS and the fact that Cisco is rock solid and their support is great.

Like

Reliability.

Like

We had a large deployment of Cisco products. Being a seasoned Cisco user, it makes it easy to deploy the ISR G2 in the network at different tiers. The variety of available interfaces and variable bandwidth as per platform makes the business case easy to use them as per requirement.

Dislike

Cisco costs a lot more than some of the other vendors.

Dislike

Difficulty in getting support with complex issues.

Dislike

The ISR G2 performance is really hit when used for the QoS because they use the same CPU for control and data plane

    1941 Routers - Dependable Work Horse

    4.0
    Dec 16, 2019
    Functional L3 device (1941), capable of Internet and WAN edge security, NAT and all expected IGPs. Problems were few & far between with issues arising due to poor usage of debug commands so definitely the CPU utilization max could be hit fairly easily for a router running WAN edge purposes. I believe that's to be expected with the low tier G2 offering.
