Controllerless Networks

Hello Team,

I have 18 instant 205 already working which VIP IP 192.168.0.100 relies on vlan 1 untagged from the switches as well.

Settings on this is DHCP for each AP and configured only VIP 192.168.0.100 with NO custom settings.All good so far...

Clients reside on the vlan 2 which is another network 172.16.1.0/21 with no issues 

Customer wants to change the mgmt vlan to another vlan than 1 .

Let's say vlan 100  which has another subnet 192.168.100.0/24 network .

The plan is to change the Virtual IPs on all vlans and tag the traffic from the HP siwtches .

How can I do that to all APs at once with minimum downtime ?

I have tried bringing down the POE, configure the switch to add tag vlan the MGMT network , bringing up the POE .This brought one APs up with new mgmt IP but with VIP from the old network , then changed the settings , reboot and tried with another AP.When the 2nd AP came up with new mgmt IP did the same thing but could not take the config from the other one.

Thank you in advance .

Do you say that I should bring down all APs , start one , change the VIP by adding vlan VIP id and then power on one by one ?

Yes, to avoid problems where different IAP's on different VLAN's are trying to elect themselves as the master due to not being able to communicate with the master IAP you made your changes on. When I've completed this before it is easier to shutdown all the IAP's except one, make all the changes you require then power the rest of the AP's up in this VLAN.

The IAP which you have made your changes on would've already elected its self as the master and the remaining IAP's in the VLAN would download their configuration from this master IAP.
