Can you do Wireless Networking in HA Clustering with a Spark appliance

Eikkichi — Thu, 27 Jun 2024 11:15:37 GMT

HI All,

Im trying to setup a cluster with 2 x 1575 Units .

But trying to cluster the Wireless networks that is centrally managed.

FWA

WIFI : 172.16.101.252/24

Cluster IP : 172.16.101.2

FWB

WIFI : 172.16.101.253/24

Cluster IP : 172.16.101.2

This gives out DHCP , Security zone was set to internal and then no zone . No traffic was allowed out.

But it seems in a tcpdump there are arp requests and the cluster IP of .2 isnt responding to any of internal IPs

For awareness in sk178604 we see the following limitation.

SMB-2286 In Centrally Managed appliances, the standby member does not bring down the wireless networks.
