here's our current setup
50Mbps Docsis 3.0 cable -->ASA5505 -->SMC 802.11n bridge --->Cisco AP1252 -->2960G 8 port - with a 24 port unmanaged daisychained to it ...right now clients only connect on the 5ghz only using MSRADIUS PEAP for client connects to MS WIN2008 PDC & Wireless bridge is WPA2-PSK on 2.4GHZ
obviously not the best setup... some things are monitored with CNA others ASDM
the first question is 891w -vs- SA520W main differances in IPS functionality performance/throughput etc.. the ASA5505 appears to have lower specs in VPN/Firewall throughput (150mbps & 50mbps for VPN ) -vs- the SA520W at 200 & 65.... The IPS module for the asa5505 what additional things does it cover ... the SA520W appears to have all 100/1000 ports -vs- the more expensive 891w which only has 10/100 ports... while it's true the WAN is only 50mbps Docsis 3.0 does support up to 300 it appears that the new 890 routers are almost outdated and should have included 100/1000 ports.
can the 520W wireless bridge using WPA2-PSK to either an AP1252 or an AP541N
we are thinking of the following setup
Cable modem --->SA520W --->AP541N -->ESW540-24P-K9 (or use the AP1252 Dual Radio's... would it support Standard POE with this ESW switch ? or require MCS be turned down in power to support both radios.?. or just be able to use a single Radio? as we were told a 3750G switch would be needed for full 18.5W POE
instead of using 2.4ghz for the bridge & 5ghz for the clients.. (since the AP541N only support 2.4 or 5GHZ switchable not both) can both the clients & bridge all use MS Radius PEAP to Win2008 PDC or would we be forced to use WPA2-PSK
can this all be managed using a single tool...? and if so what are the differances between CCA & CNA as they basically appear to do the same thing?
our other thoughts were an intergrated router with Cable modem 802.11N & Gigabit in a single box.
we looked at the 1941W problem is it doesn't support a Docsis 3.0 HWIC and it's much more expensive.
thanks again for your assistance as Cisco appears to have many overlapping products.
