Re: [nv-l] Removing devices

[Paul Stroud <nvladmin@gmail.com>]

It should happen automatically. There are certain things however,
mentioned previously, that will cause problems. If the device itself
does NOT remove the interfaces from the MIB table, NetView will
not remove them. Also, as Leslie mentioned, if the oid_to_type file
contains a captial S for the device type:

#  S    Treat the device as if it supports secondary addresses, but does
#       not report them via SNMP in its ip.ipAddrTable.  These devices
#       have interfaces that are added, deleted, and then re-added by
#       netmon in a regular pattern.   The S option prevents the deletion
#       of the secondary interfaces.

This could also cause netmon not to delete the interfaces.
