Hi Juan,

the difference is useful by example if you have between your netview box and 
the router a firewall which gives you access to only one ip network to manage 
the router. You won't be able to ping the other interfaces (e.g. ip-adresses) 
of the router to check if they are up. SNMP-Poll queries the MIB-Table of the 
devices to see if the interfaces are all up and, hopefully, the snmp 
implementation of the router is telling the correct status so you are able to 
check those interfaces without having an ip route to them.

Hope this helps

In my experience, a demandpoll on an snmp-status-polled node does
indeed check the status of each interface. Instead of showing the list
of interface addresses being pinged at the top of the output, it shows it
further down, by interface index number, with ifAdminStatus and
ifOperStatus
for each interface. If it is not doing this for you, you should call
Support.
If I have not understood the question, please ask again....

Cordially,

Subject:  [NV-L] demandpoll in Netview 6.0





Hi all,

     I've just tested Netview 6.0 and I found that demandpoll on a
SNMP-polled device is different to demandpoll on a IP-polled device. The
latter polls (with ping) all discovered interfaces but the former doesn't
poll any interface. Does anybody know why it is done like this? advantages?
replacement for missing functions (other than using MIB browser)?

Regards,
Juan
