Serial link Upgraded Do I need to change router setting 1

[999Dom999]

We have just upgraded our site to site serial kilostream link from 512 to 2mb. I can't see a speed setting on our 2600 routers, is this automatic or do I need to make a change? This is this output from sh int on the serial interface:

Thanks for any help

Well it looks like you are pushing out about 1.9 Mbps right now so I'd say the upgrade was a success. However there are errors showing on the interface that were probably caused when the telco was doing the upgrade. I would suggest clearing the interface statistics and see if those errors start appearing again.

As rburke stated, it appears to be working just fine. The speed setting is somewhat arbitrary and is used more for statistical purposes rather than funcitonality. I would change it regardless. To make the change, go the serial interface of your router via config mode and type the following command:

speed 2000

Speed" is not a valid command on a Cisco serial interface.

999Dom999, your telco is providing the clocking on this circuit and so you don't have to do anything.

Thanks a lot guys, I've cleared the counters on the interface and so far no more errors. All seems to working fine.
