Skip updating port setting if no value is entered

[eroche]

So updating a script I did where I am updating a switchport settings as a whole instead of individually updating on each setting.

Say I want to update the following (names not correct syntax) :

• name
• enabled
• poe enabled
• vlan
• port type
• allowed vlans

If I select Access as port type it will skip the allowed vlans question but when I go the list out what I entered to verify as well as the updateDeviceSwitchPort command I get an error that allowed_vlans is blank and has no value assigned.

So is it possible to somehow skip the setting that are blank and not try to list or update?

Here is my code. API is an environment variable and switch SN is hardcoded but removed.

Thanks in Advance!
