Device Profiles (v2)
Saved profiles
Ready.
Profiles are stored on the backend. Use Docker volume mapping to persist them across restarts.
Create new profile
How it works:
- Fill in configuration in SNMPv3, NTP, and AAA tabs
- Return here and enter a profile name
- Click Save profile — all form values will be captured
The profile stores: SNMP credentials, NTP servers, AAA/TACACS+ settings.
Want to edit an existing profile? Select it from the list and click Load — the editor will appear.
