slow performance

htmltobing · ‎07-02-2003

hay Guys,

I have problem with my old switch 2924-xl.

Why every compaq I-PAQ connected to my old switch have very slow performance.

When I check there is many number of total packets dropped on the fast ethernet but no value on total error.

Can somebody be my savior.

Thanks you

Thomas

Check the duplex and speed settings.Try to hard code duplex and speed on both switch and machine.

Thanks

I already check the duplex and the speed settings, but I don't know how to hard code dulpex and speed, would you please tell me how..?

Thanks again

get into switch( thru console or telnet ) ,

sw#conf t

sw(conf)# int fa 0/1 ( put the no. on which machine is connected)

sw(conf-if)#duplex full

sw(conf-if)#speed 100

sw(conf-if))#exit

you can also try for other combination like half duplex and 10 Mbps ,but be sure that settings should be same at both side.

If your cable are hand-made (versus purchased), you need to have followed the correct cabling standard. Just putting the wires in the same order at each end is not good enough.

The color order should be (with the connector end facing away, clip down):

Green-White, Green, Orange-White, Blue, Blue-White, Orange, White-Brown, Brown.

This is EIA/TIA 568A, EIA/TIA 568B is also valid (and popular). 568B is the same order, with the green and orange pairs swapped (OW, O, GW, BL,BL-W, G, BR-W, BR).

Bad cabling frequently presents symptoms of slow performance, with indicators showing "Late Collisions" and "CRC Errors."

I agree that the likelyhood of bad cabling being the problem in your case is somewhat low, but it is frequently overlooked.

You may want to check to see that portfast is enabled for those ports as well, the connection delay may be confusing to the Ipaqs, or be the cause of the overall time-to-connect and communicate.

FWIW
