With a configuration of multiple Vlans, ( Native, data, voice, dmz, etc.) I'm using Cisco 2821 ISR for routing and Zone based firewall (ZBF). If I monitor data network, I can see all PC's/Servers, main switch and router. If I monitor DMZ, only router and dmz switch, In neither can I see the native vlan. I'd like to monitor all switches, routers on the net. Should I monitor only native vlan? Or should I create a ZBF rule to allow specific ports between native and data vlans?
(not desireable due to security) Any directions / suggestions would be appreciated.
I don't think enabling the ZBF should affect the discovery process, unless you're disallowing the specific access method you are using to access the router/switch(i.e., telnet,ssh,snmp...) I'm assuming you are only seeing the clients/devices on the same VLAN you have placed the ON100 on? What kind of switches are connecting the clients?
Let me know if you would like to setup sometime to chat, it might be a bit quicker to talk through this in realtime.
