I need to create a trunk between a Cisco 3560 and a Juniper EX4200
I am perfectly happy with the the Cisco side and want to only allow 1 vlan across the trunk, which I was going to configure on the 3560 side.
Has anyone any experience on trunking to a Juniper Ex4200
Looking at the Juniper side it looks like I just set the port as a L2 uplink.
Thanks

You can allow certain vlan(s) on the trunk by using the memeber command:
here is the command:
user@switch1> show configuration
interfaces {
ge-0/0/13 {
unit 0 {
family ethernet-switching {
port-mode trunk;
vlan {
members [10 20 30 40];

Hello Roger,
EX-4200 are multi layer switches. The most important difference is that Vlans/broadcast domains have names and need to be associated to an 802.1Q Vlan-id.
the following commands can be of help
ex-4200> configure
ex-4200# set vlans INTER-SWITCH vlan-id 100
ex-4200# set interface ge-0/0/0 unit 0 family ethernet-switching port-mode trunk
ex-4200# set interface ge-0/0/0 unit 0 family ethernet-switching vlan members INTER-SWITCH
ex-4200#commit
ex-4200#exit
the default is that no vlans are allowed on the trunk on the EX-4200. multilple Vlans can be permitted by using the last command that refers to the vlan object name and not the to the 802.1Q vlan-id
commit is required to apply the change in junos
Hope to help
