Serial Line Speed Limit!! open original image

I have a Cisco2801, two serials configured as a frame-relay switch. On serial 0/2/0, there's an 805 attached with a back-to-back cable. On serial 0/2/1 there's a 2612 also with a back-to-back cable. The 2612 circuit comes up fine. On the 805 however, I get the SPEED EXCEEDS 512K INTERFACE SHUTDOWN message. I wonder how I can make the 2801 serial interface behave as a 512K....



Weird thing is I'm able to get an HDLC link with no complains from the



805, but not a frame-relay one.


Any comments will be appreciated.


Thank you. Charles.

I seem to recall (very vaguely) that at one time there were some low end routers that were 'licensed' for use up to a certain line speed.

Maybe this is one of those?

Yes this is a router with a serial capable of only 512K. They are pretty recent though, but a low end product from Cisco. Model Cisco

805. Anyhow I was able to bring the main router (2801) down to 512K with Merv's tip.

Thank you all!!
