Can't get HP1810 VLAN to work

Wed Oct 01, 2014 11:43 pm

I try to configure my router RB2011UiAS-IN to work with vlan from HP 1810 24g switch. I've made a small test to verify if it works based on the information from this site which has the setup I aim for : ... -dhcp.html

Currently on HP switch port 1-10 are respektive untagged and tagged on trunk port 23. One vlan for each port.
Trunk port 23 is then connected to router on ether5.
Ether1 is WAN, Internet
Ether2-4 has printers and wifi AP connected.

I have created interfaces, ip adresses and pool, dhcp server for vlan with help from the above blog.

What I try to accomplish is to get internet connectivity in respective vlan and currently I don't get any ip from dhcp when I test to connect a computer to port3 on the switch. (I have just created one vlan1101 on router for test purpose)

Can someone helpful guide me through my issues?

Re: Can't get HP1810 VLAN to work

Thu Oct 02, 2014 5:43 pm

you don't provide full info, however... it seems you are using ether5 as trunk port to your 1810 switch. If so, then:
a) to simplify things, ether5 should not be member of any bridge, every vlan is added "on top of it";
b) wire from ether5 goes to trunk port 23 on 1810 switch. That port should be tagged "T" with same vlans as you export from Mikrotik;
c) if your port #1 on switch 1810 is untagged "U" on vlan 1101, then make sure PVID on that port is also 1101 (if that dumb switch allows such config);
d) make sure save config on 1810, afaik it's web managed switch that looses config upon reboot ;)
e) forget DHCP, sort out things with static IPs first. You should get ping to gw from PC connected to switch;
f) if you want to go outside to internet, you should add SNAT or MASQUERADE rule on /ip firewal nat using ether1 as your outgoing interface.
g) enjoy.

I noticed that "dhcp1101" server is configured on ether5 interface, but in this case it should be on "lgh1101" vlan interface.
