Hi everybody,

I need some help, I need to do redundancy with 4 hp switchs.
You can see the network with the attach file.
If think it's quite simple but  want to know if I'm going wrong.
Do I need to enable rstp on every switch and do I need to do some port trunking ?
Also do I need to do something special with vlan configuration ?

PCs are linked to IP phone that are tagged by the omnipcx. No other special vlan, all machines need to communicate between them.

Thank you.

RSTP on every switch: yes
Trunking: no (unless you have insufficient bandwidth)
>Also do I need to do something special with vlan configuration ?
Not that I am aware of

Think about unplugging link 3; set the root/backup root bridge on switch 3 + 4 (set spantree priority 4096, set spantree priority 8192).

Who is the default gateway in your diagram? You might have to configure VRRP for default gateway redundancy....

Hi, thank you for the answer.
I don't need vrrp as I don't use layer 3 on the switchs.
There is just one WAN gateway, a cisco asa appliance.

It is just STP (Spanning Tree Protocol).

STP will determine the fastest path and then will disable the other redundant paths.  If the Active Path fails it will activate one of the others automatically.

Hi,
I don't understand the meaning of your post ?
Do you mean "You have to use stp" ?

STP is the Protocol that the Switches use to manage multiple redundant paths.

If you connect multiple paths without STP the whole thing stops working.  Only one path can be active at any one given moment,....and STP is what manages that.

Ok I already knew that but thank for your precision.
In fact for the moment only 3 paths are linked sw1-sw2/sw2-sw3/sw3-sw4
I will enable rstp, link the cables and see what's going on.
