Hello Folks,
i am searching for a solution of following problem. I have to
connect an 2900 XL Series Switch and an 3600 Router. in my 3600
are two 10base/t modules. when i connect a 100mbit device to the
switch, all works fine. when i connect my 3600 eth 0/0 to the
2900-switch... no link!

i tried to connect the 3600 to another (noname-)switch - and it
works.
i allready played with speed, duplex, keepalive and so on... but
no success.

if anyone can give me a helpfull hint?

TIA

Samz

If you're sure both the switch and router are good, and you don't get any lights
at all when you connect them, then you're using the wrong cable.  Remember that
you need to use a "normal" straight-thru ethernet cable to connect a router to a
switch.  If you're using a crossover cable, it won't work.  Some 3rd-party
switches do auto-crossover and will work with either cable, but Cisco doesn't.

If that's not it, post the relevant interface sections of both configs, along
with results of "sh int" commands for them.

Hi Samz,

Would have to advise that you start at the begining...

Set switchport to auto and check that the ports are up and data can pass

likewise for the router.. if the 3600 has ip address can you ping devices in
the range ? (pc connected directly to the router)
have u applied any config to any of the devices..? if so what is it.. can u
utilise  x -over cable between both ports on the 3600..?
do u get a link ?
