ASA/PIX Discovery in topology

Hi:

   I  am wondering whether there are any protocols/mibs that can be used for discovering ASA/pix in network just like CDP for Cisco Routers/Switches?

No. The best you can do is query the device with snmp to do things like retrieve the configuration and values of counters (input, output, etc.).

That's 'by design'. The theory is that firewalls should not be giving up too much information about themselves to discuvery type of tools. Some people even recommend turning off CDP on routers and switches - a bit extreme in general in my opinion good practive for publicly exposed devices / interfaces anyhow.

Marvin:

  Thanks for your response. I  do understand the design considerations of an ASA for not publishing through CDP. I  am interested in a way  to figure out all the connections ASA has with other devices in the network,  like interface info etc.

I am wondering whether there is any specific MIB or some other means to query for the connectivity info.

Thanks,

Chandra.

You can query the ASA using SNMP, if you have allowed it, and get information as noted in this document. Of particular use may be the following:

"

To get information about interfaces in either the admin or user context, you can use the IF-MIB's:

snmpwalk -v 2c -c public  ifDescr
IF-MIB::ifDescr.1 = STRING: Adaptive Security Appliance 'inside' interface
IF-MIB::ifDescr.2 = STRING: Adaptive Security Appliance 'outside' interface
IF-MIB::ifDescr.3 = STRING: Adaptive Security Appliance 'mgmt' interface

"
