Hi,
We used to use 4 x dell 5324 switches.
Then we discovered VLANs
We changed to 1x5324 switch which has 4 vlans.
However when the switch is flooded with traffic on the internet facing vlan (e.g. by a big port scan/attack) then the other vlans drop ports/ have problems.
Is this normal?
How can we stop this happening?
The internet vlan(vlan1) goes to our firewalls which then goes to vlans 2,3 and 4.
Do we need to use a separate switch for traffic from the internet (from multiple routers) to our firewalls (multiple HA)?
Or is this something to do with tagging? I set all ports to Untagged.
Thanks
Simon
