Dial up modem upgrade 56kbit X2 to 56kbit K-Flex

Back when people primarily used dial up to connect to the internet, I had a 56 Kbit X2 US Robotics X2 modem. Unfortunately my Internet Service Provider (Etisalat in the UAE) only had  K-Flex modems. This meant that I could never really connect faster than around 33kbits /sec.

Since we were billed based on the number of hours of usage, I decided that upgrading to a K-Flex modem would give a potential speed increase up to 52kbits /sec. Not a huge increase, but it certainly did improve performance and a 10 megabyte download which previously took 41 minutes would now take 26 minutes.

Experimenting with Cacti and SNMP on my cisco router

I am trying to measure and graph interface speeds as well as router cpu usage, so decided to use Cacti and SNMP. The interface speeds seem to be working OK, but I am still having difficulty with the correct values for cpu usage.

I will post the graphs when I get a chance.
