Hi everyone
I have a 3550 and the customer that returned it said that port 7 was
bad. How exactly do i go about testing the port? any command that will
show the statuses of each port?
Thank You

Put port 7 as an access port in a vlan (pick one), connect a pc or
laptop to it. Connect another PC in another port (pick one), but
ensure that it is set as an access port in the same vlan as port 7.
Put both nodes in the same layer 3 network (192.168.0.1 and
192.168.0.2 as an example - with 255.255.255.0 netmask), and run ping
tests. If that works, then layer 2 is working appropriately. Its
possible that it has a higher level problem with port 7, but
unlikely. Make sure you match speed/duplex settings as well on ports/
pcs or laptops.

Show ip int brief will show ports. Show interface f0/7 or g0/7 should
show interface statistics to see if something obvious is wrong. If
the port refuses to come up when you do the stuff above, then the port
may indeed be bad (make sure you put 'no shut' on both ports).

Thanks for your reply. I am really a newbie at this stuff. Would it be
possible for you to give me step by step instructions. I am starting
for my CCNA like in a few months and all I do at this company is
usually small stuff like password recovery and show versions and stuff
like that. If its not too much to ask could u give me step by step
command instructions? thank you

Just my personal opinion, but: IMHO, Yes, it -is- too much to ask
for step by step command instructions to test everything that might
be wrong about a port on a 3550. The 3550 is a "Layer 3 Switch",
which means that it is really a router, with the usual layer 2
operations and routing; and it has extensive QoS facilities as well.
Your customer might have seen anything from link failures to
spanning tree problems, right up to QoS problems. Detailing all
of the commands to check all of the possibilities would be a lot of
work.

Someone in your company must have dealt with the customer; what
did the customer say was wrong with the port?

If you do not have a Cisco CCO web site access you should register

cco.cisco.com


You may want to check out the Cisco doc "Resetting Catalyst Switches
to Factory Defaults"

I got it to factory settings thats not the issue im having. I also am
registered at Cisco. I just need someone to please tell me how to ping
test a C3550, as in step by step commands and what all I need to do
it. This one is returned and according to the customer, Port 7 is bad
and I need to test that to verify. Thank you

config t
int f0/1
switchport mode access
switchport access vlan 2
no shut
int f0/7
switchport mode access
switchport access vlan 2
no shut

May need to go into vlan database mode and create vlan 2, else just
use vlan 1 or whatever. Plug the nodes into both ports (make sure
speed/duplex matches), if its auto on pc side, make sure its auto on
switch side).

IP the nodes per my previous posting, and ping. See what happens.
However, I completely agree with the other posters that this ONLY
verifies basic layer 2/3 connectivity, and who knows what your
customer was trying to do. Could be trunking, QoS, or any number of
things. Could also just be a lack of knowledge of what they were
doing. Things to keep in mind.....

Like Walter has said, the switch is also a layer 3 switch, which
providing step by step instructions to test is impossible.

If you have the switch set to factory defaults:

Test layer 2 connectivity, plug a PC in port 7 and another PC in any
other port, setup each PC on the same network and ping each other, if it
works then layer 2 is working fine.

Your client may have just enabled a configuration that disabled port 7.

THANK YOU EVERYONE I GOT IT WORKING
special thanks to trendkill

With the limited knowledge you have of the device, it becomes
increasingly important that you get a clear indication from the
customer, what constitutes "bad".

What did they see, what did they experience that lead them to their
conclusion?
