CISCO 3750 fiber switch need to change connection speed to 10baseT
All,
Is it possible to change an interface on a 3750 fiber switch to a 10 base T connection speed to accomidate an old device? I have been using a lot of question marks in my commands, but I have not been successful. Currently all interfaces show media 100 Mb/s and 100BaseFX. How can I set them to 10BaseFX?
Thanks,
CH

what does "speed ?" under an interface show?
ASKER
I might not be providing what you are looking for, but media type is 100BaseFX and I set the Bandwidth to 10000 Mb/s.
The reason I asked you to provide what "speed ?" show is because it will give you options available either 10/100/1000.
If you see 10 is available then you can change the speed to 10Mb by using "speed 10" command and "duplex full or half" following the command.

There is no speed mentioned when I do a show int.
config t
int gix/x
speed ? <enter>
It should show something like below:
10 Force 10 Mbps operation
100 Force 100 Mbps operation
1000 Force 1000 Mbps operation
auto Enable AUTO speed configuration
int gix/x
speed ? <enter>
It should show something like below:
10 Force 10 Mbps operation
100 Force 100 Mbps operation
1000 Force 1000 Mbps operation
auto Enable AUTO speed configuration

unrecognized command. It's looking bleak huh?
what does it not recognize? which line?
ASKER
Sorry, I should have explained better. entered the following:
config t = good
interface fastethernet 1/0/3 = good
speed ? = unrecognized command
This is a fiber switch with MT-RJ connectors. Maybe there would be someway to use a fiber WIC in an expansion slot that could be made into a 10 Base T?

Is this CatOS?
If then run this command to find out available speed.
show port capabilities 1/0/3
It will say something like this:
Model 3750
Port 1/1
Type 10/100BaseTX
Speed auto,10,100
Duplex half,full
To set the speed:
set port speed 1/0/3 10
set port duplex 1/0/3 full or half
If then run this command to find out available speed.
show port capabilities 1/0/3
It will say something like this:
Model 3750
Port 1/1
Type 10/100BaseTX
Speed auto,10,100
Duplex half,full
To set the speed:
set port speed 1/0/3 10
set port duplex 1/0/3 full or half
ASKER
It is, ver 12.2
show port capabilities 1/0/3 fails at capabilities
then I tried: show port that printed secure port numbers which is 0, and total available.
I then tried the: set port speed, but that was unrecognized command.
Then I tried: set port ? but that was unrecognized command.
I can set duplex, that command is: duplex half or full

Can you do "sh ver"?
If it is IOS then it should say this on the first line.
Core#sh ver
Cisco IOS Software, CxxxxE Software (CxxxxxE-UNIVERSALK9-M), Version 12.2(55)SE3, RELEASE SOFTWARE (fc1)
and also sh int status or sh ip int brief?

I just saw that it is "FastEthernet" which should support 10/100.
Not sure why it is not taking "speed" command.

You have bandwidth configured on fa1/0/3 and I think that is why you don't have speed option.
Try the other interface and see if you have "speed ?" option.
I would just do this.
config t
int fa1/0/3
no bandwidth 10
speed ?
(if 10/100 available)
speed 10
duplex full

You can not change the port speed of a fiber-optic module. If it's a 100-FX module, it will work at 100 only. The speed is a fixed value.
You will need to purchase a 10Mb SFP, as Infamus suggests.
