Validating discovery
Discover the topology of the network. If the deployment includes a single
IP Availability Manager
on a large or extra large platform, discover the network in limited
portions: for example, discover groups of one thousand managed network devices. Monitor the discovery process and review the discovered topology after each discovery.If the network includes Hot Standby Router Protocol (HSRP) groups or virtual
routers, ensure that they are discovered.
For
IP Availability Manager
and Performance Manager, validate the discovered topology by reviewing a segment of the network that is well known. Always
confirm possible discovery errors: if an expected device does not appear in the topology, ping the device to ensure that it is accessible. It is not unusual for discovery to find more devices than you expect; if this is the case, confirm that the
devices exist.
