How can I enable the SFP ports of a ICX6450%3F

Hello,

 

I´m new in the world of switches, I hope you can help me...

 

I have two ICX6450, I need to connect them through fiber usinfg SFP transceivers.

 

I configured the switches, assigned IP addresses to both and I made a succesful test through copper (ping between the devices) to check communication.

 

Now, I am trying to communicate them using the GBIC's, but with no succesful results so far... 

 

I used the command sh int e 1/2/1 ( that is the slot/port that appears on the CLI when I insert the GBIC), the text that shows up says that the 10GigabitEthernet is down. I tried to use the command portenable 1/2/1 , but the CLI marks it as invalid...

 

How can I change the status to "UP" in order to achieve communication?

 

Thanks in advance

What SFP's do you have? If they are 1G you will have to do the following

 

int e 1/2/1

speed 1000-full

enable

 

Depending on code level you may then have to write memory and reload.

Re: How can I enable the SFP ports of a ICX6450%3F

So i guess i ran into the same Problem:

 

Setup:

1 ICX7450-24 with 3 * 40G Modules (1 * 10GB 1/2/1  & 8*1GB (1/3/1 - 1/4/4)

1 ICX6450-48 with 1 * 10GB in 1/2/1

2 ICX6430-48 as stack with 4 * 1 GB in 1/2/2 + 1/2/4 & 2/2/2 + 2/2/4 , aswell as a direct kable in 1/2/3 + 2/2/3 fpr the stack

1 ICX6430-48 with 2* 1GB in 1/2/2 & 1/2/4

 

Each Switch is updated to 8030c and got an ip from 192.168.103.210 - 213/22

 

I managed to get the stack working and to get the 10GB connection working.

 

I cant use 1/2/1 on the 6430s for the ocnnection to 1/3/x pr 1/4/x on the icx7450 or can i? (i get nan error when i try to use the int eth 1/2/1 command, something about only for stacking or uplink)

 

So from what i read now i have to set the Speed for the 1 GB Ports to 1000-full and enable them and it should work?

 

but i also would need to create a trunk for the 4 connections from the stack and the 2 from the single ICX6430 wouldnt i? Whats the command to do that?

The 6430 is setup for stacking out of the box

 

From the stacking guide

 

When stacking is enabled, ports 1 and 3 are dedicated to stacking and cannot be used for data ports. Use the stack-port command to select only one of these default ports as the stacking port. If you do not select a defaultport as the stacking port, both default ports operate as stacking ports.

 

On the 6430, if it's not a stack, and won't be is to unable stacking, no stack enable, then reload, this will likely wipe your config so be sure to save a copy to reconfigure your switch

 

If you just want to use 1/2/1, and not 1/2/3, could could just do

 

conf t

stack-port 1/2/3

wr mem

 

Then you should be able to manage that port as a data port

 

You don't have to code speed on a 1G port, only if you're putting a 1G optic in a 10G port

 

I'm a little confused what topology you are trying to use so I can't answer about the trunk specifically

 

A diagram may help a bit
