when a new object type of "LAN" via Topology View - is created with, for example, the following parameters:
- "Subnet Address" for example "172.19.122.0"
- "Subnet Mask" for example "255.255.255.0"
Only "Subnet Address" is saved. The "Subnet Mask" will be "0.0.0.0" as default.
Release : 20.2.7 (10.4.3)
Component : Spectrum Core / SpectroSERVER
Support Engineer identified the root cause of issue and planned to fix it in a next future release 21.2.3 ( tentatively August time frame)
Workaround: use the Attribute editor. to change the LAN's object attribute called "Network_Mask" to the correct value.
