According to the docs in-band is required for Wireless? We have four
WiSM with about 600 AP's, CCA works fine but we have been having
intermittent traffic issues that appear to be related to the WiSM,
TAC case still open. Going along just fine then the traffic will
drop to zero. We are NOT using the CAS for the DHCP with wireless.
We have a CNR DHCP server inside the private VLAN with the AP's. The
clients and the CAS are on the public network...
We are servicing around five thousand client machines in the
Residence Halls, wired, using the CAS as the DHCP server. The only
issue I see is functionality isn't as great as with the CNR DHCP
server. Can't work with individual leases, at least not from the CCA
GUI. An example would be a lease is given out without an expiration
date. The only thing I can do is block it until the client releases
it, then unblock it. CNR DHCP server can deactivate and force
available which causes the client to take some action to continue to
use the lease. Other than that CAS as DHCP server works quite well.
Hope that helps... :-)

Subject: Any issues using the CAS as the dhcp server
We are deploying the Cisco NAC, inband, real-ip gateway to replace our
Bluesocket solution for authentication. The plan is to use the HA-CAS
as the dhcp servers and configuring upwards in the 100's of vlans on
the
box for our LWAPP access points.
Does anyone know of any issues using the NAC servers as the dhcp
server
versus an external dhcp server? Is there issues with handling large
numbers of vlans?
We have 2 WiSM centrally located and will be moving to OOB and
posture
assessment in the future.
Thanks,
Nancy
