VLAN 1 is not working on stack mode

[julien_ange]

Dear All,

First off please excuses me English isn't my native language.

We have two of Brocade ICX7250-48P stacked, the idea behind is to accomplish a failover , whenever switch one is down we will remain online because each server will have two ports connected to each switch.

the issue is Switch number is working fine so ive configured the second switch as stack see below

the issue as next, when I connect the cable to switch 1 doesn't matter which ports I received IP from VLAN1, when I connect it to the second switch I don't get any ip.

I don't know what I have done wrong can someone please point me to the right direction ?

this the output of VLAN1

PORT-VLAN 1, Name DEFAULT-VLAN, Priority level0, Spanning tree Off

this is output of the brief interface

@jijo_panangat Thank you for your answer, when I connect PC on the primary switch they received the IP.

when I connect to the second switch the IP is not receiving with the same device.

the switch is a Layer 3 switch and I was wondering If I can configure the web gui to have a clean idea of what in happening in the switch.

the switch has layer 3 and has already extern IP, I was wondering if I can configure the gui even the switch already has extern IP.

Ok. But, how is the PVID (VLAN 141) on this port ("show interface ethernet brief")?

Screenshot just shows that stack is managed by switch 1, and second available management module is standby. It is as it should be.

To have redundancy, you need to have all services available in case of one switch failure. It means not only that client PCs are connected to port with proper VLAN configured, but also they can reach DHCP, DNS, target services.

Also, when you connect server by 4 ports to 2 switches, it is important how are configured this ports on switch and on server, otherwise nothing will work. If server is ESXI server, for example, with multiple VLANs used, you probably want to create static LAG agregate on stack, which includes 2 ports from one switch and 2 from another switch, as well as agregate on server. Agregates must include all neccessary VLANs on both sides  (all tagged, except one).

Where is located DHCP server -- on that servers? Where is connection to Internet connected? Redundancy needs planning, otherwise you may end with nothing working because of attempt to get redundancy...

Looking on your posts, looks most probable, that NICs on server are not configured as agregate, so just the 1st NIC works, other are not used at all. Than your server is really connected to just 1 switch and that's it.  Check server NIC configuration (LAG or NIC Teaming, depending on OS you have installed on server).

By the way, from my experience main reason of switch going down is missing power, so having 2 PSU in same switch connected to different power sources (2 UPSes) hugely improves reliability. Of course, switch can fail in many different ways, but it usually happens on reboot and not that often. Windows 10 OS fails not comparably more often, than switch, and it can't be helped, as it is so by design...

Thank you for your answer.

are you suggesting to change the PVID in order to have the VLAN1 working on each ports? if yes why its working on the first switch and not second switch even the PVID is the same?

as I mentioned even a normal Windows 10 is not receiving ip from the DHCP neither from VLANS when I tag the interface.
