Spectrum hotfix patch H03 and higher introduced a password encryption for Network Configuration Manager (NCM) passwords.

Upgrading to this release on a single SpectroServer and then bringing this server online while other servers are still older than H03 will cause the passwords to get garbled.


To resolve this issue, simply change the NCM Device family password and enable password to something else and then change it back to the correct password.


  • Set password to "test" and save.
  • Set enable password to "test" and save.
  • Now, set both passwords back to the original correct passwords and save.

Once this is done, captures will now succeed.
