Hi All,

Im banging my head against a wall here.

Im trying to stack 3 switches together (2 x 2610-24 and a E2620-48), two are already stacked both 2610-24's and im trying to add a E2620-48.

I've gotten onto the console of the switch and set everything up as identical as i could to the other two

Created VLANS, Given the switch a different IP assigned the same Vlan as the default as the two existing switches.

Configured PORT's 49 and 50 as the trunk ports (TRUNK 1), and tagged them in each VLAN.

when I patch the cables into the new switch, i can no longer ping the first two switches and the network goes down until i remove the cables and patch them back to the way they used to be.

Ok, what ports are you using to connect each switch to each switch?

I can see that you've got a trunk between switch 1 and 2 via ports 25 and 26 on each switch, but what ports are you using to connect the new switch, and to which of the two switches are you connecting it to?

Currently:
Swich1 Port 25 goes to Switch2 26
Switch2 Port 26 goes to Switch1 25

What im trying to do is:
Cable from Switch1 Port 26 to Switch2 Port 25
Cable from Switch2 Port 26 to Switch3 Port 49
Cable from Switch3 Port 50 to Switch1 port 25

Highfive Gives IT Their Time Back

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

Hmmm you can't do that as you can't create trunks between dissimilar switches.  If the switches were truly stacked this would probably be possible in some circumstances, but this is uplinking not stacking.

You have to connect all ports in the trunk to the same remote switch.  Both ends should have the same configuration.

So do i create a "Trunk2" on the first switch and add the 3rd?

Yes, that would be the way to go.  You would need to connect the third switch to a new trunk on the first or second switch - whichever you want to connect it to.

So, connect switch1 ports 27-28 to switch3 ports 51-52...

Switch1
trunk 27-28 Trk2 Trunk
vlan 1
   name "DEFAULT_VLAN"
   no ip address
   no untagged 1-24,Trk1,Trk2
   exit
vlan 200
   name "Core"
   untagged 1-2,4-17
   ip address 10.0.200.1 255.255.255.0
   tagged Trk1,Trk2
   exit
vlan 250
   name "Voice"
   untagged 3
   no ip address
   qos priority 6
   tagged 2,Trk1,Trk2
   exit
vlan 210
   name "Clients"
   untagged 18-24
   ip address 10.0.210.1 255.255.255.0
   ip helper-address 10.0.200.33
