It would be easier with a diagram! Looks like you have some ProCurve/AOSS switches + at least one CX switch.
As a general comment, make sure all the switch-switch connection ports are configured the same way:
- a single untagged (aka native) VLAN with the same ID on both ports
- each additional VLAN is then tagged on the same ports
- make sure you allow the native VLAN in CX (or allow all)

Subject: Question on VLAN Configuration
I am new to this environment and currently troubleshooting an issue which appears to be a misconfiguration and needing some guidance as I am a bit confused on how this is partially working. The configuration is core -> switch1 -> switch2 -> switch3 -> devices
In the below configuration the devices on vlan 7 work but on vlan 1 do not.
Configuration
Switch 1 interface that connects to Switch 2
Running configuration:
interface 48
tagged vlan 5
untagged vlan 7
Switch 2 interface that connects to Switch 1
Running configuration:
interface 10
tagged vlan 7
untagged vlan 1
Switch 2 connects to Switch 3
Running configuration:
interface 10
tagged vlan 7
untagged vlan 1
Switch 3
interface 1/1/13
no shutdown
vlan trunk native 1
vlan trunk allowed all
If I make the below change the devices on vlan 1 works but on vlan 7 do not.
Switch 1 interface that connects to Switch 2
Running configuration:
interface 48
tagged vlan 7
untagged vlan 1
