Hi Guys,
Just had a question in regards to AP discovery when the controllers are deployed in a L2-cluster & L3-cluster.
In the version 8 guide it states the following: "At boot time, the AP builds a list of managed device IP addresses and then tries these addresses in order until it successfully reaches a managed device."
I understand the AP does ADP, DHCP, and then DNS resolution in order to discover the controller.
My question is that if two controllers are deployed in a L2 cluster how does the AP recieve the list of IPs for the managed devices. On the DHCP server can you define multiple IPs for option 43? On the DNS server can you define multiple IP's to resolve to aruba-master. I usually do not touch the DHCP or DNS server, the client normally has this configured as per what we tell them. My question here really is around the DHCP/DNS server having multiple entries?
My other question is if a client had a L3-cluster:
Area 1 with controller 1 - this AP subnet resolves to both MC's, but it sees the closet one first. Would this work?
Area 2 with controller 2 - this AP subnet resolves to both MC's, but it sees the closet one first. Would this work?
I hope my second question makes sense.
On version 6 installs I usually advised clients to use DHCP and point all AP's to the master and then push the AP's to the local controllers based on the ap-system profile
Thanks,
