Switching

Hello, We have a Virtual-chassis in mixed mode with one ex-4550 and one ex-4200 in version 12.3R6.6 as recommanded by the J-TAC.

When I run the command show interface terse, there is no ge-0/0/0 also it's configured:

1> show interfaces terse
Interface Admin Link Proto Local Remote
ge-0/0/16 up up
ge-0/0/16.0 up up aenet --> ae1.0
ge-0/1/6 up up
ge-0/1/6.0 up up aenet --> ae0.0
ge-1/0/0 up up
ge-1/0/0.0 up up eth-switch
ge-1/0/1 up up
ge-1/0/1.0 up up eth-switch
ge-1/0/2 up up
ge-1/0/2.0 up up eth-switch
ge-1/0/3 up up
ge-1/0/3.0 up up eth-switch
ge-1/0/4 up up
ge-1/0/4.0 up up eth-switch
ge-1/0/5 up up
ge-1/0/5.0 up up aenet --> ae2.0
ge-1/0/6 up up
ge-1/0/6.0 up up aenet --> ae2.0

The configuration of the interface:

show configuration interfaces ge-0/0/0
unit 0 {
family ethernet-switching;
}

The switch show that it's recognize the tranciver:

show chassis pic pic-slot 0 fpc-slot 0
FPC slot 0, PIC slot 0 information:
Type 32x 1G/10G SFP/SFP+ Builtin

Uptime 2 days, 22 hours, 38 minutes, 57 seconds

PIC port information:

16 GIGE 1000LX10 SM FINISAR CORP. FTLF1318P2BTL-J1 1310 nm 0.0

Any ideas?

Hi Omer,

One possible reason for this is that the interface may be configured as a VC port.  You can confirm this with:

show virtual-chassis vc-port

 if you see 0/0 listed, then the port has been made into a VC port and will not show up even with ethernet-switching configured.  You can fix this with:

request virtual-chassis vc-port delete pic-slot 0 port 0

 Hope this helps

EDIT:

I just tried this on a QFX5100 (slightly different software architecture), and the port still didn't show up until after I rebooted the switch, which is a bit concerning.  Let me know how you get on with your EX4550.

Thanks!

That was the problem.

It's annoying there is no mention in the configuration that is a vc-port.

And I had to reboot the 4550 too, I remember I saw it in the release notes, I don't remember where.

Best regards,

Omer Shtivi
