We are looking to double the bandwidth on one of our circuits from 300Mbps to
600Mbps. We currently use a Cisco 7206VXR with an NPE-G1 card. These seem like
very popular routers so I'm hoping a few
people on this list have them deployed. If you or a customer have these
deployed, how much bandwidth have you seen them handle? This will be handling
dorm traffic at a college so it's mostly download.
The 7206 handles our 300 Mbps circuit just fine, but we are moving it to our
600Mbps circuit. At peak we've seen the following numbers for that circuit:
30 second input rate 559982000 bits/sec, 55809 packets/sec
30 second output rate 55429000 bits/sec, 32598 packets/sec
267756984712 packets input, 333325152556755 bytes, 0 no buffer
This is the interface that connects to our provider. As you can see its almost
all download traffic. Our ASR1002 handles it without a sweat but I'm a little
skeptical of whether the 7206 will hold up.
This depends on multiple variables. The 7200 is a single-CPU platform where CPU
can go sky-high when using features like ACL's, QoS, IPv6 and you name it..
Also, changing from IOS 12.4 to 15 increased
our CPU usage with another 10%+. Stick to the bare minimum of features you
really need and you will be fine.
I do share the same thoughts as Remco. We've actually several NPE-G1 in
production environments with full BGP feed. We saw a decrease in
forwarding performance since 12.4T and up. We also recently disabled
some features like netflow and ip inspection, which seemed relatively
CPU intensive.
I do remember we were able to forward around ~700Mbps of 1500 bytes
traffic with old IOS images and no ACLs.
