•
AP200 using per station BSSID Vcell (There are no problems if AP200 is using shared
BSSID Vcell)
•
AP300 using per station BSSID Vcell
•
AP200 and AP300 on the same channel (There are no problems if AP200 and AP300
are on different channels)
•
AP200 and AP300 on the same controller (There are no problems if AP200 and AP300
are on different controllers and each controller has a unique "controller index"
configured.)
Best Practices for networks that are made up of AP200s and AP300s.
•
Try to avoid having AP200 and AP300 deployed in the same physical location,
Regionalize them
•
If the APs do have overlapping coverage, care must be taken to make sure the ESSID
profiles on both AP types are unique. The example below shows 2 scenarios first is
supported while the second is not supported.

New 11n-only Deployments
The general recommendation is to deploy 40 MHz channels in 5GHz bands, 20MHz in 2.4 GHz
band. Dedicate 5GHz to 11n-only clients. Support 11b/g clients on a single 11b/g channel on
separate AP/radio. Need to use Cat-5e (or better) Ethernet cable for APs.
HIGH AVAILABILITY DEPLOYMENTS
All controller models support a variety of redundancy options. This sections outlines a
number of ways in which high availability can be implemented.
Link-layer Redundancy
Every controller has the ability to support link-layer redundancy. This is where two or more
Ethernet ports are used in either an active-active or an active-standby configuration. In an
active-active configuration different VLANs are trunked (802.1q tagged) on the ports. In an
active-standby configuration the secondary port (e. g. G2) is in standby mode until link in lost
on the primary port (e. g. G1). In the event that the primary port goes down, the secondary
port takes over.
