I have in the network switches 2960 and 3560, but don't can type in CLI the duplex full, speed command.
the IOS in the switches is 12.2(35)SE5
thanks.
SW_NEIV_01(config)#inter gigabitEthernet 0/2
SW_NEIV_01(config-if)#
SW_NEIV_01(config-if)#
SW_NEIV_01(config-if)#du
SW_NEIV_01(config-if)#duplex?

Solved! Go to Solution.

There is only full duplex with gigabit.
There is no such thing as gig/half-duplex. No matter if it is copper ports or fiber ports.

Maybe it's the IOS. I was able to change duplex and speed on another switch which had a gigabit copper sfp.

I had the same issue on my 3750 and found out that a port in routed state can be configured for speed and duplex and a switchport cannot be. Let me know if you find more information.

this teh configuration in the interfaces:
SW_NEIV_01#sh run inter gigabitEthernet 0/1
Building configuration...
Current configuration : 59 bytes
!
interface GigabitEthernet0/1
switchport mode trunk
end
if you need more information, please tell me

Can you please post results from : "sh run int gi0/2"
Thanks,

only had configured this:
SW_NEIV_01#sh run inter gigabitEthernet 0/2
Building configuration...
Current configuration : 59 bytes
!
interface GigabitEthernet0/2
switchport mode trunk
end

What's you media-type? Are you using fiber SFP? If so, you can't specify duplex because it's full duplex by nature.

Here's the output from my switch.
Full-duplex, 100Mb/s, link type is auto, media type is 10/100/1000BaseTX SFP.
I think you can still change the speed/duplex if the port is routed and not switchport.
02-25-2009 03:11 PM
I don understand what is a port routed or how is the configuration for put a switch port routed?
02-25-2009 03:01 PM
no, don't is fiber is utp pair twister
02-25-2009 03:02 PM
Change it to a non trunk port and then change the speed and duplex.
02-25-2009 03:15 PM
i tried change this but still don't works
SW_NEIV_01#sh run inter giga 0/2
Building configuration...
Current configuration : 59 bytes
!
interface GigabitEthernet0/2
switchport mode trunk
end
SW_NEIV_01#conf ter
Enter configuration commands, one per line. End with CNTL/Z.
SW_NEIV_01(config)#inter giga0/2
SW_NEIV_01(config-if)#no switchport mode trunk
SW_NEIV_01(config-if)#
SW_NEIV_01(config-if)#duplex

mqayoolsuhsc is right. Your media type shows that Gig 0/2 is using a GLC-TX. This SFP will NOT negotiate speed/duplex setting. GLC-TX SFP negotiates to speed 1000 and FULL Duplex, period.
Hope this helps.

i belive that the matter is for the IOS: 12.2(35)SE5
