Hello all,
I am trying to get my SS5 to trunk to my Cisco 2940 switch. I followed a guide in a book however it was based around trunking 2 bonded connections. Can someone if possible give a base guide on how to trunk it. I have looked around the GUI but nothing stood out. I assume this is possible as they can both use dot1q trunking?

It's probably called "tagging" on the juniper not trunking. Cisco often confuses people with this as "trunking" in cisco terms is used to apply tagged vlans to a port, to the rest of the world it's creating load sharing groups. Most non Cisco devices refer to tagging for adding multiple VLANs to a port.
Have a look in the VLAN port assignment settings and see if you can set VLANs to be tagged on a specific port. That should sort you out.
 
On the SSGs you have to create a sub interface and assign the VLAN tags to that, you can't do it on a physical Interface itself. You just need to go to the Interface list then in the top right there is a dropdown box - set that to Sub-IF and hit new. You then pick the physical interface to make a sub interface from where you can do the usual stuff like set an IP address but from there you can also specify VLAN tag values.

Hi Guys many thanks for the replies. I have tried but cannot set this up, pics below show my current settings, I have tried configuring the VLAN's with IP's but to no avail

Ideally I would like to trunk down 2 Vlans on seperate Subnets to my Switches(s)

First VLAN would be 192.168.1.1/24

second 192.168.3.1/24 for wireless clients, this would only be allowed limited outgoing ports and could not access the other VLAN

Any chance you can give me some more pointers please :-)

you are using eth0/5 for your sub interface when there is no link on this port or an address assigned so not surprised this isn't working.

You got 192.168.1.1/24 assigned to bgroup0 which holds eth0/2, eth0/3, eth0/4 and eth0/6.
You need to create the sub interfaces with the VLAN tags on the bridge group if this is where you need that subnet and then add the wireless as well.
