The plugin you are using should be updating the names by resolving the
IP addresses back to names using DNS. If that's not happenning, check
that both the device, and each interface, have the 'Auto DNS' option
turned on.
The included plugin called "DeviceIpNamesFixed" uses the main device
name (not necessarily the SysName value) for all IP addresses. You
should be able to easily write your own version of that plugin to use
SysName instead.
