Controllerless Networks

Hi All 

I am looking for answers of below queries. Customer have Aruba controllers in Active/Standby without MM. Appreciate if anyone can clarify below queries. 

Aruba Controller Port Channel Queries:

There is no Mobility Master and Aruba Controllers are acting as Active/Standby

·        What kind of fail-over method Aruba support on Port Channels on 7210 Controllers.

o   Active/Active (Load Sharing between both physical interface)

o   Active/Standby (One physical port active at a time, if physical port fails it will use other physical port in port channel bundle)

·        Can we load balance traffic between both physical interface bundled in single Port channel.

·        Is it possible to forward control plane traffic to dedicated physical interface and data plane traffic to the other physical interface, when both interface are bundled in single Port channel. 

·        in case if there isn't cross connectivity between Active customer network devices and Aruba Controllers. Primary customer network devices in physically connected with Active 7210 controller in port channel and secondary customer network devices has physical connectivity with standby controller. If primary customer network devices fails, how does Aruba Controller and AP will behave during customer primary network device fail-over. 

·        In above scenario where primary customer network devices is connected with Active Controller and customer secondary network devices is connected with Aruba standby Controller. Do i need to create single port channel or separate port channel between customer and Aruba Controllers. 

Regardless of whether a Mobility Conductor is in use or not, the managed device can be configured to use a Port Channel. It is based upon the LACP standard detailed in 802.3AD. Both interfaces are Active/Active. You cannot segregate specific traffic within a Port Channel to a specific interface. For the event of a failure of a controller and how the AP will failover to the standby member will determine on the configuration of the redundancy that you decide upon. Whether this is HA, VRRP, LMS/BLMS etc.
