I have a Cisco C2900XL switch running the c2900XL-h2s-mz-112.8.2-SA6.bin. I have two questions regarding this switch as I am not that knowledgeable when it comes to cisco.
- First off is anytime I plug a serial cable from a windows box into the switch, it restarts? Prior to plugging in everything is running fine (4 machines plugged into this switch) and then nothing after plugging in the serial. So I bring up my hyperterminal and hit enter and it boots up.
- When I run ping commands from the boxes plugged into the cisco switch I get the following results on all boxes.

Every third attempt is significatly faster. Again this happens on all 4 boxes with the same results. Does cisco switches just function this way? I thought I would include the running config as it is right now. FYI this switch is the switch for all machines in the DMZ. It's plugged into a BSD firewall. I will admit my config is basic as I do not know cisco products that well.

I am sure there are ways to improve the configuration so that performance is better, but I need some direction please. This is an old switch that I would rather not have to replace.
