Let's talk about switches and ping

Question

Hi,&nbsp;Recently bought an additional GS108PEv3 switch to power up some Access Points.I accessed to its management interface to configure it (Static Ip, VLAN settings,...)After that, I put it where it belongs in my network.But then, as I couldn’t access this new GS108PEv3 switches web management interface from PC B, i made some tests.&nbsp;So, I have the following network situation (see image attached).For the purpose of the test, all devices were set with static IPs.&nbsp;Switches are set up with 4 different VLANs, and linked through 802.1q trunk ports.The entering port used for PC A and PC B are in the same VLAN.&nbsp;PC A&nbsp;:- Can ping all the switches, but not PC B.&nbsp;PC B&nbsp;:- PC B can ping the 24 ports switches, but gets no response from the 8 port switch.- PC B can ping PC A (but the other way around doesn’t work).&nbsp;Why is that&nbsp;? Is this layer 2, layer 3 related&nbsp;?&nbsp;&nbsp;

L2.&nbsp;Show us the VLAN and PVID config of all switch ports and the PC ports involved.

Thank you for your answer.Attached, you'll find 3 pictures to show you all the config.&nbsp;I probably found the reason why PC B didn't answer to ping =&gt; ICMP was off in its Firewall settings; so, this point is not an issue anymore..I still have no idea why I can't ping my 8 port switch, nor access to its management interface from afar (I must be directly plugged in one of its physical ports to do so).&nbsp;I tried to access the management interface in VLAN ID 10, like illustrated on my attached picture; but I tried on VLAN ID 1 too, with other physical ports, thinking that VLAN ID 1 (default) was maybe the management VLAN (but after some reserach in this forum, there seems not to be such a VLAN on this model; management interface should be accessible through all VLANs).&nbsp;I'm probably missing something trivial, but I just don't see it...

So, is the configuration of my VLANs ok ?Still no access to my GS108PEv3 Management Interface switch, when I'm not directly plugged on it.Where should I look next ?

Ok, it was partially my fault.I thought I had tried to access my switch through VLAN1, but had picked the wrong cable.So to access my switchs web administration page, I have to :- Put my PC on the same subnet as the static IP of my GS180PEv3 switch (of course)- Plug the cable of my PC directly in a physical port of my GS108PEv3 switch - In this case any port - any VLAN works.- Plug the cable of my PC in any switch of my network, but in a physical port belonging to VLAN 1.&nbsp;So VLAN1 seems to be default management VLAN for my GS108PEv3 switch, after all.
