LMS 4.0 Discovery,

[adamgibs7]

Hello,

I have enabled PING and CDP for discovery, I ran a discovery and found swithes through CDP but i can't find firewall and branch routers through ICMP the seed devices for icmp module is the first devices (switch) which i added manually and it is seen in  DCR. Then i thought of doing alternate i.e.For firewall and branch Routers i added them manually they are successfully added but they are seen found by system not by icmp. WHY ?????????????????

All devices are pingable and all devices are reacheable through SNMP,

Thanks

The Discovery ping sweep module will do unicast pings of a subnet (based on your address ranges), then contact each reachable node with SNMP.  Those nodes that are SNMP reachable are added to DCR.  When you say you add them manually and it works, what exactly do you mean?  You can add any device to DCR manually, and it should succeed.  DCR does not contact devices.  The real test is if you can run an inventory report on the devices and see data.  If that works, then Discovery must not be able to ping the devices (or they are not responding quickly enough).

See https://supportforums.cisco.com/docs/DOC-9005#Troubleshooting_CSDiscovery .  If you enable debugging for the Ping Sweep and System modules, the ngdiscovery.log should indicate why the firewalls are not being discoverd.
