Hi all
I have the following setup:
Vlans:
1: default vlan
10: admin
20: guest
Hardware:
1 x CISCO RV180 router (DHCP server - vlan 10: 192.168.1.0/24 - vlan 20: 192.168.2.0/24)
1x HP 1810-24 (port 23/24 Trunk static (untagged in Vlan1) - port 1-12 vlan 10 (TR1 en TR2: tagged)- port 13-22 vlan 20 - (TR1 en TR2: tagged)
5x HP 1810-8 (port 7/8 Trunk static (untagged in Vlan1) - port 1-3 vlan 10 (TR1 en TR2: tagged)- port 4-6 vlan 20 - (TR1 en TR2: tagged)
Connection of the switches:
Cisco-RV180 port 1 (vlan 10) connected to 1810-24 (switch ip 192.168.1.30) port 8 (vlan 10)
Cisco-RV180 port 3 (vlan20) connected to 1810-24 (switch ip 192.168.1.30) port 22 (vlan 20)
1810-24 (switch ip 192.168.1.30) TR1 connected to 1810-8 (switch ip 192.168.1.31) and TR2 to 1810-8 (switch ip 192.168.1.32)
1810-8 (switch ip 192.168.1.31) TR1 connected to 1810-8(switch ip 192.168.1.33) and TR2 to 1810-8 (switch ip 192.168.1.34)
1810-8 (switch ip 192.168.1.32) TR1 connected tot 1810-8 (switch ip 192.168.1.35)
I've made sure that all the links between the switches are the same speed and type.
I've stacked them on top of one another on my desk, connected the switches and router and everything works fine. I tried all vlan ports on all the switches to get a correct IP form the CISCO, no problem everything is OK. The trunk prots show up as active.
When I tried this setup in the actual situation, the trunk ports remain down. I've tested the CAT6 cable running between the swiches and it is fine. When I connect say port 8 on the 1810-24 (switch ip 192.168.1.30) with port 3 on an 1810 (switch ip 192.168.1.31) in the actual situation, both ports show up as active.
I can't figure out what is wrong.
Help would be appriciated!
