Hi,
We currently have 2 PowerConnect 2724 network switches that we use on one of our subnets. They are connected together with one connected to our primary firewall and the other connected to our secondary firewall. The firewall uses Nokia VRRP protocol to cluster them together.
Also on these switches I have a port-based VLAN in which one of our leased line is connected to one switch and the other leased line to the other. Also connect together and each switch VLAN connect to the internet port on the firewall.
Last weekend one of the switches failed however when it did it brought both switches down at the same time. The engineer report that the switch appeared operational until he power cycled the switch in which then it failed to power up again. At that time access to the subnet was restored.
What would have caused this?
