hp procurve v1910 vlan lacp wlan trunk not working as expected

hi,

i have a rather simple setup with two v1910 switches here.

all the servers, the firewall and some printers are connected to the main switch with 24 ports

from the mainswitch 4 links are connected to the subswitch with 48 ports. all the clients are connected there

the zyxel usg 50 firewall is connected to port 10 on the mainswitch.

there are 3 vlans

1 - customer 1 vlan
2 - customer 2 vlan
40 - customer 1 guests wlan vlan

port 10 (firewall) is configured as trunk port, untagged 1, tagged 2,40

i configured vlan 2 and 40 as vlan interfaces on the firewall (internal interface)

the 4 links between the switches are configured using lacp and the bagg is configured as trunk, untagged 1, tagged 2,40

port 5+6+13+15 on the mainswitch are configured as access ports, untagged 2

port 41 on the subswitch is configured as access port, untagged 2
port 43 on the subswitch is configured as trunk port, untagges 1, tagged 2,40

there is an unmanaged poe switch (dlink) on port 43, where are 4 accesspoints (zyxel nwa5301) connected. these are managed by a zyxel nsc2500 and on these accesspoints there are 3 wlans:

company 1 (vlan1)
company 2 (vlan2)
company 1-guests (vlan40)

first problem:

if i connect a client to port 5 on the mainswitch, it gets an ip address for customer 2 and can access the server (connected to port 10) and the internet - fine

if i connect a client to port 41 on the subswitch, the client gets no ip and cannot reach anything. what have i done wrong?

second problem (related to 1 of course)

only company1wlan is working as expected. on the other wlans the clients don't get ip addresses.

thanks for your help

Hi, the v1910 is a HP Comware based switch you may need to add DHCP helpers if you are using the same server with multiple scopes for the various different vlans.

In comware 5 it should look something like this (obviously add your own info)

dhcp relay server-group 1 ip 192.168.2.1

interface Vlan-interface2
 ip address 192.168.1.1 255.255.255.0
 dhcp select relay
 dhcp relay server-select 1

Hope this helps
