A Set of clustered S3300-28X need a bit of guidance
Hi All As the title states in my work office we have 3 S3300 Switched linked together and they all work great we have a link cable going into SW1 and it shares the access across the switches ...
Welcome to the community!
Would it be possible if you could provide a network topology (what ports are the switches connected to each other)?
You would generally configure a LAG on the switches for redundancy.
Lastly, please let us know what configurations are done to the switches (are there LAGs or VLANs involved).

Thank you for the reply.
I will try answer all your questions.
I can add screen grabs of the switch info from the webgui if that'd be easierThese are our core switches
We have three
Switch 1 is our ustairs office
Switch 2 is for our servers and customers serversswitch 3 is for our workshop.
on The Switches we use Ports 25+26 to connect to each othercurrently there is a main link to our Firewall plugged into switch 1
we would like to plug a backup link into switch 3
We have many VLANS spread acrtoss the switches
Currently it does not appear as though we have LAG enabled on any ports and there appears to be STP configured.
This setup was inherited by myself, I t was not setup by me.Hi ChayneC,
For the switches, is this how the connection goes? Please see the following:
p25 of Switch 1 connects to p25 of Switch 2
p26 of Switch 2 connects to p25 of Switch 3
p26 of Switch 3 connects to p26 of Switch 1
If these aren't the case, it would be best to provide a network topology to better assist you. Also, please confirm if all switches are using RSTP since the SRX uses RSTP by default unless that was configured differently.

Morning Jerald
Thank you for the further information
Using your information and some i gathered online
What i did was.
Created two Lags spread across SW1+SW3 (Lag1 = Sw1/g23 + Sw3/g23) (Lag2 = Sw1/g24 + Sw3/g24)
I also enabled Local Preference mode on both Lags.
After setting this up I plugged link cables from the relevant FW in each.
and all is good,
no dropped pakcets and no sensor warnings on any of our hostsed and internal servers.
