Switching

Hello.

I need to use all four 10Gb port as network ports.

so I'd disabled xe2/3 as VC ports but link is still down

thanks!

Is this the procedure you are using to remove the port as a VC link?

 

https://kb.juniper.net/InfoCenter/index?page=content&id=KB17821

 

Is there another link still active to keep the VC traffic flowing or are you removing this completely from the VC?

spuluka

no, I used

request virtual-chassis vc-port delete pic-slot 1 port 2

request virtual-chassis vc-port delete pic-slot 1 port 3

 

should I use procedure from your link?

 

There was no any VC configured, only default config.

 

smicker

DAC is recognized - it's native juniper DAC and it works fine at xe-0/1

Assuming you mean xe-0/1/3, you can run show chassis hardware to confirm that the installed optic is recognized. If so you'll then want to check the cabling and its polarity as well as that of the end device connected to it.

I've always used the delete option--I think disable simply turns it off but leaves the port as a VC uplink.

What does 'show virtual-chassis vc-port' show?

smicker

show virtual-chasis show nothing - look at my first post.

and yes - I've used "delete" option, but no luck.

 

That isn't what I asked for.

sorry, my mistake.

I'm a little confused now over the exact nature of the current problem.

 

I assume this switch was a member of a VC and now is not.

You are trying to use the old XE VC port as a normal XE port.

 

What seems to be confusing is which port we are talking about your title has xe-2/3 which I assume is xe-0/2/3

your command in first post has xe-0/1/3

 

But in any case the VC command do show that no interface is currently setup as a VC port.

 

So I think the next step is to verify that your interface is seen:

Does the interface show up using 

show interfaces terse xe-#/#/#

this will verify that the device sees your hardware on the expected port

 

Is the optics module recognized:

port xe-0/2/3

show chassis pic fpc-slot 0 pic-slot 2 

or make pic slot 1 if the interface is xe-0/1/3

 

are there optics data

show interface diagnostics optics xe-0/2/3

Hi, spuluka.

I assume the main problem is my poor english. sorry.

No, this switch had never been member of VC  -it's standalone switch.

ports xe-0/1/0 and xe-0/1/1 are in use from the first day and xe-0/1/2 and xe-0/1/3 was empty until now.

 

and I'm talking about those ports and here is no any xe-0/2/x ports.

 

here is output:

Thanks for the update.  You appear to have a hardware problem.  This could be either the optic (DAC cable in your case) or the expansion module.

 

Try disconnecting the DAC if it is still inserted and running the port tests again.  If the port shows up the cable is defective.

 

If this is still down, try removing the expansion module.  Keep it out for 2 minutes and insert it again.  Now look for the interface again before inserting the DAC cable.

 

If this is still missing then the module is defective.

DAC is fine -  I have another ex3300 and tested DAC there - it's fine.

also I've tested this DAC at xe-0/1/1 of this ex3300 - it's working.

 

which expasion module your are talking about? ex3300 has four 10gbe builtin ports - there is no expansion modules.

 

This seems likely to be a hardware issue with the switch then.

 

One last check, are these combo ports that can go either ge or xe?

See if you have a configuration or a recognized port in the ge version.

show interfaces terse ge-0/1/2

show configuration interfaces ge-0/1/2

 

Assuming these are also not present then your hardware has failed.  You will need to open a JTAC ticket on the support site to verify and get an RMA replacement.

You are right - there was config for ge-0/1/2 and ge-0/1/3 ports.

but after deleting this xe-0/1/3 is still down.

will try to reconnect DAC a little later.

 

I have two more ex3300.

I'd deleted VC ports 0/1/2 and 0/1/3 at each of it.

and the same issue there.

only xe-0/1/0 and xe-0/1/1 are working as Network Ports.

I think that is not hardware malfunction.

it's software bug or something like that.

 

 

 

after you remove the ge-0/1/2 ge-0/1/3 configuration what interfaces if any show up in 

show interfaces terse

 

After the configuration removal can you insert the xe optic cable and run again

show interfaces terse 

to see if the interface shows up as xe

 

I've not use th ex3300 but on the acx platform with the dual ports the interface type ge verses xe is trigged by the optic being in the slot.

xe-0/1/3.0              up    down eth-switch

there no any ge-0/1/x =(

 

 

So I want to confirm that you have the DAC cable connected on both ends when this is taken so that there should be a link.

 

And if you move the DAC to port xe-0/1/1 the cable works and we show link up.

absolutely.

and I have two other EX3300 with exactly the same behavior.

 

 

Seems odd behavior and I don't see any mention of these ports being somehow unusable in the documentation.

 

The only other thing I can think to try is using standard sfp+ optics in the ports as a verification but with your DAC tested and working on the adjacent port it seems not likely to be the issue.

 

I think you will need to open a JTAC ticket on this unless someone else has seen this before.

I don't have active support contract, so I can't ask JTAC.

Problem solved  - at the other side was buggy Netgear M4300 switch.

changing FW fixed those box.
