First off, yeah Ive got some old switches, I know.

I have a Juniper EX4550 switch that I'm swapping some links over to, I have some Extreme switches, a Cisco ME 4924, a bunch of Netonix and UBNT switches and they all work fine.

Except the Cisco ME 3400 switches. I get a link up, but no traffic will pass through the trunk.

Heres a sample of the config:

EX4550:

ge-0/0/19 {

description KCC-Roscommon;

ether-options {

link-mode automatic;

}

unit 0 {

family ethernet-switching {

port-mode trunk;

vlan {

members [ 14 200 303 1212-1250 1333 2000 3521 ];

}

}

}

}

​

ME 3400:

interface GigabitEthernet0/1

switchport trunk allowed vlan 14,200,303,1212-1250,1333,3521

switchport mode trunk

media-type sfp

​

I have a laptop plugged into port 2 of the ME switch. Its an access port with vlan 1333.
If I create an access port on the Juniper, I pull an IP and pass traffic,
On the Cisco I get nothing.

I have this ME switch set up locally right now so I can view the console. But the 2 out in the wild wont pass traffic..
Im also going to be replacing them with Juniper switches soon, but Id like to get this up if I can..

Any suggestions?
