I need to enable the 4 Gigabit (Fiber) ports on the Switch for interconnectivity between switches.  When I try to determine if the ports are enabled, I enter this command: #show run interface Gigabitethernet 1, I get the response of % incomplete command.  When I try #show run interface Gigabitethernet 1/1 I get the response of % invalid input detected at marker "^" marker.  Can someone please assist me?

It would be "show run int g0/1"

Hassan, Thank you.  That allowed me to show all of my ports.  What would be the command(s) to enable these ports to pass IP traffic?

if you go for default layer 2 mode for the interface :

conf t

int g0/1
no shut


and you should be good to go :)

Hassan, That helped a lot, thank you.  I found that it was necessary to input: #int g1/0/1 (1-4) for one switch and g4/0/1 (1-4) for the second server.  I then typed "end".  Then I ran Copy system:running-config nvram:startup-config.  I did this on both switches.  I then connected a fiber patch cable between the two switches to test connectivity.  whn I connected my laptop to the switch that was not connected to the router, I could not get a dhcp ip from the router.  Am I missing a step (or 2)?  Thanks!  :)

i need to see the config for both switches and the router, so type # sh run
in every device and get me the result here.

I can not.  destination host unreachable.

I can ping 192.168.1.31 if I connect a cat 6 patch cord between SW1 and SW2 via a switch port.

i think you have problem of  unsupported GBICs here so The idea is most GBICs have almost the same architecture, and are supposed to work on almost all Vendors, but sometimes the IOS may not support that piece of hardware; a more recent IOS version might. but in any cases, here's how to make it work using these hidden commands


SW1(config)#service unsupported-transceiver
SW1(config)#no errdisable detect cause gbic-invalid

SW2(config)#service unsupported-transceiver
SW2(config)#no errdisable detect cause gbic-invalid

Hassan,  The solution that you provided worked perfectly!  Thank you so much!  I had a 4/21/2014 deadline to get these switches installed, configured and operational on the network.  Thanks to you, it looks like I'll make that deadline.  Again, many many, thanks!
