Morning guys,
still working on my A5500 and now that the IRF is working fine I'd like to confirm/check some things before doing something wrong.
First of all : VLANs
I will have 4 1910 switches connected with LACP to my 5500 stack.
On each 1910 I will have several VLANs configured ....all carried by the 5500s.
1 - I assume that I shall configure the VLAN/VLAN interface on the 5500 and then configure the ports on the 1910 to match the existing VLANs created on the core. I am right here?
2 - I see the words "hybrid", "tagged" and "untagged". What does hybrid stands for? If a port is untagged on VLAN 1on the 1910...will the 5500 be able to route the traffic coming from VLAN 2 to the VLAN 1?
I assume that I have to tag every vlan on every 1910 port wich have an LACP uplink to the 5500...but want to check with you folks.
DHCP Relay :
I will create one DHCP pool for each VLAN I have on my DHCP server to provide each subnet with a proper IP@ and my 5500 will be the DHCP-Relay.
1 - Should I enable the DHCP snooping on the 5500 & 1910? [dumb question....]
2 - Will that be a problem to have all the subnets redirected to the same DHCP server by the 5500?
Many thanks to you all!

Solution1) Yes
2) The ports between the 5500 and 1910 should be mode trunk (tagged). Hybrid is a mode where you can have more than 1 untagged vlan on a trunk, kind of confusing. But trunk it is.
1) Depends. If you will have clients/users connected to the 5500 then both. Otherwise just the 1910.
2) Thats no problem, the server will know which IP do give out based on the IP of the relayed vlan.

Re: A5500 - DHC Relay & VLANs
Hey Fredrik,
thank you very much for your concise answer!
If I'm correct it's the second time you help me out of trouble :)
Just have a last question though : port on 1910 AND 5500 should be tagged [link between IRF stack & 1910]?
I'll do the conf' now for test-environment and let you know how it goes!
Cheers & enjoy your WE!

Re: A5500 - DHC Relay & VLANs
Hi,
I hope everything goes as planned :). Yes the link between the 5500 stack and the 1910 should be tagged if you have multiple VLANs spanning over it.

Re: A5500 - DHC Relay & VLANs
Ola!
Everything went as planned....but not quite :)
Actually thing is I have 2 VLANs [100 & 101] on a 1910 and the VLAN interfaces are on my 5500.
PVID on ports between the 1910 and 5500 is 1
Ports are tagged 100 & 101
Vlan1 - 1910 IP@ : 10.10.10.1 /24
Vlan1 - 5500 IP@ : 10.10.10.254 /24
They both ping each other with I have the following issue for my other Vlans.
In a few word :
On 5500:
VLAN interface 100 : 192.168.100.254
Port 1 HYBRID Tagged 100 -101 / untagged 1
OSPF : 192.168.100.0 /24 directly connected - Nexthop is Interface vlan 100 on 127.0.0.1
On 1910 :
Vlan 100 is created without an interface
Port 24 access vlan 100
Port 1 HYBRID tagged 100 - 101 / untagged 1
Computer plugged on port 24 [IP 192.168.100.1 /24]
Computer can ping the Gateway on the 5500......but 5500 can not ping the computer.
I'm a bit lost here...
Do you have a clue? :)
Is the Hybrid mode the issue? [does not make sens to me]
EDIT : Yes was hybrid...I'm dumb.... :=)
EVERYTHING IS NOW FINE!!!
Cheers!

Re: A5500 - DHC Relay & VLANs
Actually.....It's failing again.
I can ping all my VLAN interfaces on my 5500 from all my VLANs but the 5500 does not forward traffic from a VLAN to another....
Help still needed :)
Many thanks.

Re: A5500 - DHC Relay & VLANs
PCs got the 5500 as default gateway? Can you post a display route from the 5500.

Re: A5500 - DHC Relay & VLANs
Yes, PCs have their Vlan interface on 5500 as their gateway [and so default route on route print].
Dis route on my 5500 does not show anything....

Am i missing something?
Plus, on the 1910 I can't access the management mode via CLI [_cmdonline-mode on does not take my super password] so I've made port 1/0/1 on 1910 trunk + tagged for vlan 2-201
Edit :
On 5500 HTTP interface in IPv4 routing I see all my vlan interfaces ==>

Re: A5500 - DHC Relay & VLANs
Remove all the ip-subnet-vlan from the VLANs, its not needed for intervlan routing, might mess things up.
