cisco 3548 xl and ports broken

[kuismsu]

Hello could you please help me.

we have several ports broken in cat 3548 xl ( fast 35,37,38,39) when we are trying to connect new workstations to them, ports do not work.

there is over 80 procent packet loss.

all other ports work ok.

Do you konw if there is a known problem in cat 3548xl's. ( could not find anything in bug toolkit)

our version is flash:c3500XL-c3h2s-mz-120-5.3.WC.1.bin

Model number: WS-C3548-XL-EN

System serial number: FAB0534M322

i thank you in advance,

best regards,

Susanna

Hello Susanna,

do you get any POST errors when you boot up the switch (you can check that with the exec command ´show post´) ?

When you say ´packet loss´ are you referring to counters in the ´show interface FastEthernet´ output, and if so, which counters are you seeing that are increasing ?

What do you have connected to the malfunctioning ports ?

Have a look at the document below, it contains comprehensive troubleshooting procedures for the 3500XL:
