Switching

Hi

 

I am new an switches and i try to make a trunk over a aggregatte interface and an "normal" one.

 

when i do:

 set interfaces ge-0/0/21 unit 0 family ethernet-switching port-mode trunk
set interfaces ge-0/0/21 unit 0 family ethernet-switching vlan members all

 

then the interface is no more shown under default vlan.... 

 

run show vlans
Name           Tag     Interfaces
default      
                       ae0.0*, ge-0/0/1.0*, ge-0/0/2.0, ge-0/0/3.0, ge-0/0/4.0, ge-0/0/5.0, ge-0/0/6.0,
                       ge-0/0/7.0, ge-0/0/8.0, ge-0/0/9.0, ge-0/0/10.0, ge-0/0/11.0, ge-0/0/12.0,
                       ge-0/0/13.0, ge-0/0/14.0, ge-0/0/15.0, ge-0/0/16.0, ge-0/0/17.0, ge-0/0/18.0,
                       ge-0/0/19.0, ge-0/0/20.0
vlan100        100   
                       ge-0/0/21.0*
vlan200        200   
                       ge-0/0/0.0*, ge-0/0/21.0*

 

why ?? and how to get the default vlan also over the interface???

 

thanks

The documentantion states "... If you use the default factory configuration, all traffic originating on the VLAN is untagged and has a VLAN identifier of 0 ..."

So untagged frames (the ones in the "default vlan") won't travel over a trunk interface.

I would try one of the following three alternatives:

1. Build a "new-default" VLAN, assign a VLAN-ID to it and make all ports currentlly in the "default" VLAN members on this "new-default" VLAN
2. Try to assign a VLAN-ID to the predefined "default" VLAN. (set vlan default vlan-id xx)
3. Try to define the VLAN-ID 0 as the native-vlan for the trunk interface (set interfaces ge-0/0/21 unit 0 family ethernet-switching native-vlan-id 0)

I don't have access to any EX box so I'm not sure if 2 or 3 will work.

hi

 

i have rebootet the switch and now it works on one interface:

 set interfaces ge-0/0/21 unit 0 family ethernet-switching port-mode trunk
set interfaces ge-0/0/21 unit 0 family ethernet-switching vlan members all
set interfaces ge-0/0/21 unit 0 family ethernet-switching native-vlan-id default

 

now i try the same on int ae0 ...error with commit:

ethernet-switching'
    Access interface ae0.0 cannot have native-vlan-id
error: configuration check-out failed

 

bug in software?

 

version 9.3R4.4

 

cheers

Ok error found... my fault...

 

i have to delete  "delete vlans default interface ae0"

 

thanks

This works for me !!!

 

3. Try to define the VLAN-ID 0 as the native-vlan for the trunk interface (set interfaces ge-0/0/21 unit 0 family ethernet-switching native-vlan-id 0)
