If the interface is in async mode then the highest it can go is
115.2Kbps. Only in sync mode can it go 128Kbps.

Is it a high speed serial interface, or is it a serial
asynchronous/synchronous? If it is a serial a/s, the highest speed that
you
can configure is 128k. This would be like on a 2520 that has two high
speed
and two a/s serial ports.

Hi there,

I'm trying to configure clock rate on frame relay switch as 256k. The
router

showed me an error message.

bb1(config-if)#clock rate 256000
%Error: Unsupported clock rate for this interface

when I used "?" it shows that I can configure till 4000000 ?

bb1(config-if)#clock rate ?
        Speed (bits per second)
  300
  1200
  2400
  4800
  9600
  14400
  19200
  28800
  32000
  38400
  56000
  57600
  64000
  72000
  115200
  128000

  <300-4000000> Choose clockrate from list above

Do I have to pick a value from the above list or a correct value between

300-4000000 ?

thanx
NetChild,
