Dear everyone,
I has 4 sites: Site 1, Site 2, Site 3 and Site 4 (Data Center). Each sites has 1 x Primary internet link to connect to Site 4 and 1 x backup link to Internet. If primary link has problem, users connect to Internet through backup link.
I am going to propose the number AP:
Site 1: 10 x AP-115 and Secondary DC.
Site 2: 5 x AP-115 and Secondary DC
Site 3: 3 x AP-115 and Secondary DC
Site 4: 1 x Wireless Controller 3200 and Primary DC
Site 4 (Data Center) can point to point to Site 1, Site 2, Site 3. Wireless Controller put at Data Center to manage all APs at Site 1, 2,3. Site 1, Site 2, Site 3 can't connect together.
Questions:
- When the connection to controller is lost, AP can automatically authenticate users locally with Secondary DC and allow data traffic go out to Internet through back-up link at each site.
Which is the best solution for high availability without Redundant Controller?
Thanks,
Khang
