Why does the last octet of the subnet mask return to 0 regardless of what I set it to?
Certain versions of software for the Spectrum Master (MS2721B, MS2723B, and MS2724B), the VNA Master (MS2024A, MS2026A, MS2034A, and MS2036A) and the BTS Master (MT8222B) have an issue with the display of the last octet of the subnet mask. In these versions of the software, if you set the last octet of the subnet mask to a value other than 0, then view the setting when the ethernet is NOT connected to another device, the last octet of the subnet mask will be displayed as 0. However, the correct subnet mask is stored, and if you connect the ethernet connetion before powering up the tester, the subnet will be displayed correctly.
