Hi,
I have to configure three switches (One 2920 and two 2510).
I made it works but I have some questions in order to make it he right way.
First configuration :
My two 2510 are connected directly to the 2920. I made a lacp trunk on each 2510 and two on the 2920. I tagged the trunk on every VLAN and every switch. The layer 3 switch has a static IP address on each VLAN. IP routing is activated.
Each 2510 has a ip address acquired by DHCP on VLAN2. show IP address show me a correct IP. The 2510 have a default gateway (The IP of the 2920 on VLAN 2).
Configuration Two :
2920 is connected to a 2510. The other 2510 is connected to the first 2510.
If I tag my LACP Trunk (As I did just before) the last switch can't receive an IP address. If I give a static IP it can't be ping or ping other networking equipment).
To make it work, I had to tag my LACP trunk on every VLAN except the VLAN 2 on which the LACP trunk is untagged. In this case I can receive an IP address and ping every networking equipment in LAN (I also can give a static IP address).
In the other case i can untag ethernet port correctly and it works but I can't manage my Procurve by network.
My question are : How to configure it the right way? In my first configuration should I untag the trunk as I did in the other scenario? Is it correct to do it that way or will it cause networking problems ?
The only way in the configuration is to untag the trunk on the management VLAN?
Thank you !
