[c-nsp] wireless lan controller and remote ap

Tue Jun 5 11:47:30 EDT 2007

The 8 AP H-REAP limitation has been lifted. You can have as many H-REAP AP's
on a controller as you like. The limitation was marketing driven, and as far
as I know, it was never enforced.

There are some limitations with H-REAP relating to RRM and location
services. Check out the deployment guide:

http://www.cisco.com/en/US/products/ps6521/products_tech_note09186a008073612
3.shtml#t7

However, with only 2 AP's per building (19bldgs/45AP's) RRM is not going to
be an issue and you will not have enough AP's for accurate location based
services. The Controller will report "rogue" AP's but you will have to go
hunt them down yourself. You may need to implement QoS on the WAN to meet
the latency requirements.

In my experiences most people pass on redundancy. The licenses are expensive
and wireless access is a convenience but not a core business requirement.
Just get smartnet on the controller.

Lightweight is beautiful! Once you try it you'll never go back to standalone
AP's.

If I had to be perfectly honest......I hate making changes to 24 AP....
50 would really be a pain.  If this is a School district..... why do
they have to have local access.  Is each school Firewalled?  

Someone did recommend multiple controllers for redundancy which is a
good Idea.  But if the schools are not Firewalled then you should be
able to make it work without HREAP.

Just my two cents.

Thanks for the info,

Well there is a few reasons that I wanted to go with cisco instead of a 
different company, but my mind isn't made up.

So as far as I can tell, i'm limited to 8 access points if i use 
H-REAP.  Controllers at each site is definitly out of the budget range.

I'm interested in the rouge access point security (I know some kid or 
better yet a staff member will try to bring in there own ap).  With 50 
AP's i'm not to worried about being able to push out configs to each 
access point.  If I had to make a change to all of them I could fine the

time.  The other concern I had is that without a controller what 
security options do I have?  Are there other things I should be looking 
into or planning for?

Thanks,
Dan.
