Serial Cable Speed

In my home lab I have 2 2501's connecting to each other through a back to back serial cable to simulate a WAN between two separate LAN's.

My question is what is the fastest speed I can get out of this sort of connection. Is this set by the clockrate? I would like to share the Internet connection from the one side.

Thanks

The speed of the connection is directly controlled by the clock rate and is indirectly controlled by the kind of cable inteface that is used. The serial interrface of the 2501 supports several cable standards. If the cable is RS-232 you will have difficulty getting speeds much above 64 K where if you have a V.35 cable you can get speeds of T1 or E1.

Re: Serial Cable Speed

Hi,

the fastest speed is 4000 000 bps (4Mbps).

I confirm thatthis fast speed is set by clock rate.

GN-2500-YDE(config-if)#clock rate ?

Speed (bits per second)

1200

2400

4800

9600

19200

38400

56000

64000

72000

125000

148000

250000

500000

800000

1000000

1300000

2000000

4000000

<300-4000000> Choose clockrate from list above

GN-2500-YDE(config-if)#end
