Correct ACL rules to isolate WiFi traffic from other VLANs?

Since you want to permit WAN traffic, matching only any, you need to have a permit any any at the end. Basically, you want to deny traffic in and out of the Wi-Fi VLAN. For each of the other VLANs you ...

Is temperature sensor on zero enough to prove PoE Control Module is failed?

(converted from comments) The "Total Power" figure should show what the PSU can deliver, regardless of what's currently in use. The "0 W" pretty clearly shows there's something wrong. Possibly, the ...

DHCP option 43 on switch Dell PowerConnect 5500

You will have difficulties towards configuring dhcp on the dell 5524 which is a layer 2 switch. A good switch in my experience, but it isn't a layer 3 switch. You should use a layer 3 switch that ...

How to prioritize ICMP time exceeded packets

A switch forwards in hardware but ICMP messages are handled by the CPU - so you'd need to look at the CPU load, not the amount of regular traffic. OSPF messages are created and parsed by the CPU as ...

Dell PowerConnect 5548P no power to Ubiquiti ER-X

I'm dumb and didn't think of the voltage coming from the switch. An adapter is needed to transform 48V from switch to 24V.

Stacking Pair of Dell PC2724 Switches

I don't think the 2724 switches support stacking (making both chassis act as a single switch). If more bandwidth is required than a single link provides, you can create a link aggregation group (LAG) ...

Dell PowerConnect 5548P no power to Ubiquiti ER-X

Ubiquiti is very loose with the term PoE. The ER-X uses a proprietary 24V variant (as PD and PSE). It's not compatible with IEEE PoE as provided by the PowerConnect 5548P.

PowerConnect 5500 Series VLAN routing problem

VLAN 1 is the flat 192.168.69.0/24 VLAN 10 is 192.168.0.0/16 192.168.69.0/24 is a subnet of 192.168.0.0/16, making your routing ambiguous. You'll need to separate that properly, ie. without overlap.

Do I have to change to /16 instead of /24 to set up these VLANs

Setting the subnet to a /16 might cause some issues with broadcasts. Remember that your broadcast traffic is always the last address (the .255). I'm not sure what else might happen. Haven't tried ...

Dell N2000: switch will not respond on configured in-band IP

The only thing that I have spotted at the moment is that you have no default route. Currently you have traffic only destined to x.x.8.164/30 routed out of VLAN 4010. If this interface goes to the ...
