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... :-) -----Original Message----- From: Cisco Clean Access Users and Administrators [mailto:[EMAIL PROTECTED] On Behalf Of Nancy Watson Sent: Tuesday, October 07, 2008 16:57 To: [email protected] 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.
