Cisco Catalyst 1300 issues
by Corey Thompson 30 Mar '26

30 Mar '26

I've been using NAV for well over a decade with very few issues... Recently, we've integrated a few Cisco Catalyst 1300 series switches to our network and I do not get cam data from them, nor do I get Multicast or Broadcast packet metrics Looking at ipdevpoll log only see theses warnings: [WARNING zen.pynetsnmp.agentproxy] Packet for x.x.x.x has error: Unknown oid. OIDS: [OID('.1.3.6.1.4.1.9.9.117.1.1.2.1.2.67109505')] [WARNING nav.mibs.power_ethernet_mib.powerethernetmib] [statuscheck 192.168.3.20] device response has bad table index .17.2.99 in POWER-ETHERNET-MIB::pethPsePortTable, ignoring Which seemingly shouldn't cause the issues I'm seeing, but maybe.. Nearly 500 devices on our NAV, and I've never had to do this deep of troubleshooting with it, wondering where to start, and if anyone else has Cisco Catalyst 1300s in their NAV? Corey Thompson

Announcement: NAV 5.18.0 released
by Morten Brekkevold 30 Mar '26

30 Mar '26

The first feature release of the 5.18 series of NAV is now out! The source code is available for download at GitHub [1]. New packages for 11 (Bullseye), Debian 12 (Bookworm) and 13 (Trixie) are available in our APT repository [2]. ## Security - The CSRF cookie is now marked as secure when needs_tls is enabled in webfront.conf, matching the existing behavior of the session cookie. (#3829) - Passwords are no longer leaked in cleartext in Django error emails when LDAP authentication crashes. (#3870) ## Removed (developer-centric) - Removed obsolete Docker-based test environment. Replaced by test suite changes that can run in 'normal' development environments. (#3849) ## Added - Rooms and locations can now have multiple names (aliases). Aliases are searchable throughout NAV -- in the navbar, global search, device history, maintenance, netmap, network explorer, status widgets, and the REST API. Aliases can be managed in *SeedDB* and via bulk import/export. They are displayed on room/location detail pages, in search results, and in SeedDB list views. (#3314, #3315, #3815, #3818, #3819, #3820, #3821, #3822, #3823, #3836, #3840, #3841, #3844, #3851, #3852, #3868, #3880, #3895) - Added support for two-factor authentication (TOTP), OAuth2, OIDC, and SAML login via django-allauth. Authentication can be configured through the new TOML config file webfront/authentication.toml. (#3622, #3676, #3834, #3862, #3873, #3889, #3934, #3936) - Added a report of devices without a known uplink in the topology. - Debug log runtimes of individual NAVbar search providers. ## Changed - Auditlog entries can now be sorted by individual columns. Hyperlinks to more details are now provided for actors, objects and targets that still exist in the NAV database. (#3776) - Updated markdown dependency to 3.8.1. (#3812) - Downgraded spammy WARNING log about alerts referencing deleted objects to DEBUG level. (#3927) ## Changed (developer-centric) - Standardize vendored JavaScript library management. Vendored JS files now follow a consistent <name>-<version>.min.js naming convention and are tracked as npm dependencies for easier version management. A vendor.py tool is included to automate installing and copying vendored files. (#2470) - Tox environments and GitHub workflows switched over to uv for dependency management. (#3859) ## Fixed - Fix network explorer search not working after the first search per page load. (#3853) - Fixed l2trace crash when tracing through a netbox with no associated prefix. (#3866) - LDAP login no longer crashes with a 500 error when a user cannot be found during group membership verification. (#3871) - Fix report column tooltips ($explain_) not showing when the column also has a $name_ override. (#3876) - Fixed a crash in SeedDB bulk import when IP addresses contain trailing whitespace. (#3884) ## Release notes We always advise you to have a look at NAV's accompanying release notes [3] before upgrading. Happy NAVing everyone! ## Links [1] https://github.com/Uninett/nav/releases [2] https://nav.uninett.no/install-instructions/#debian [3] https://nav.readthedocs.io/en/latest/release-notes.html#nav-5-18 -- Best regards Morten Brekkevold Senior engineer, The Data and Infrastructure Division Phone: (+47) 735 57 802 Sikt – Norwegian Agency for Shared Services in Education and Research www.sikt.no

Announcement: NAV 5.17.1 released
by Morten Brekkevold 27 Feb '26

27 Feb '26

The first maintenance release of the 5.17 series of NAV is now out! The source code is available for download at GitHub [1]. New packages for Debian 12 (Bookworm), 11 (Bullseye) and 13 (Trixie) are available in our APT repository [2]. ## Fixed - Fix collapsed multiselects in status tool filters (#3797) - Event engine now yields to overdue scheduler callbacks between processing queued events, preventing long event batches from blocking time-critical tasks. (#3798) - Added missing index on netboxentity.deviceid to speed up lookups by device. (#3794) - Fix crash when rendering navlet error responses due to missing navlet ID (#3802) - Fixed a session crash (UpdateError) on the login page that could leak cleartext passwords in Django error emails. (#3803) - Fix chart widget failing to load images from URLs without query parameters (#3805) - Fixed sc.05.16.0001.sql migration failure on PostgreSQL 14 caused by ambiguous || operator when concatenating an integer without an explicit ::TEXT cast. (#3806) - Fixed a crash in Netmap when the topology graph exceeds memcached's max item size. The graph is now returned successfully even when it cannot be cached. (#3795) - Improved active IP collector query performance (~10x) by utilizing partial database indexes on the arp table more effectively. (#3793) - PortAdmin's "commit configuration" endpoint now returns 503 instead of 500 when the device is unreachable or does not support configuration commits, and no longer triggers spurious admin error emails for these expected operational failures. (#3801) - Turned support for REMOTE_USER back on. Regression caused by the new auth-system and its complicated route to the finish line. ## Release notes We always advise you to have a look at NAV's accompanying release notes [3] before upgrading. Happy NAVing everyone! ## Links [1] https://github.com/Uninett/nav/releases [2] https://nav.uninett.no/install-instructions/#debian [3] https://nav.readthedocs.io/en/latest/release-notes.html#nav-5-17 -- Sincerely, Morten Brekkevold Sikt – Norwegian Agency for Shared Services in Education and Research

Unable to upgrade nav 12 in debian 11 to any upper version.
by Secundino Grau 17 Feb '26

17 Feb '26

Hello, I have a fully working nav 5.12 instance and when I try to upgrade to 5.13, 5.14, 5.15, always have a lot of internal server errors 500 , and I'm unable to get graphite work again. If the process of upgrade is always within debian 11 packages, no success. I tested upgrading from debian 11 to 12, and then upgraded NAV but not success! Please, does anyone know if there are some steps in the upgrade process that I have missed? Thanks in advance, S. Grau

Announcement: NAV 5.17.0 released
by Morten Brekkevold 13 Feb '26

13 Feb '26

The first feature release of the 5.17 series of NAV is now out! The source code is available for download at GitHub [1]. New packages for Debian 12 (Bookworm), 11 (Bullseye) and 13 (Trixie) are available in our APT repository [2]. Please be sure to check the release notes [3] before upgrading, as there may be recommended changes to your config files. ## Security - Enable CSRF protection in entire NAV web UI (#3395) ## Added - DHCP usage statistics graphs are now shown on VLAN and prefix pages when found in Graphite (#2373) - Added "more than" / "less than" option to the "Last Seen" filter on the Room view interface list (#3313) - Added hyperlink to management profile options in SeedDB netbox form (#3643) - Added browse tree and description search for easier maintenance task component selection (#3778) - Added support for SNMP v3-based CAM data collection on Cisco switches (Adds support for SNMP v3 context switching for logical MIB instances) (#2811) - Added script to generate GitHub, blog and e-mail release announcements from CHANGELOG.md ## Changed - Finally switched from NAV's homegrown authentication system to Django's own. This makes NAV compatible with a lot of 3rd party libraries, and is a necessary step to support MFA. This is a big change. Test thoroughly before putting this version into production. This is especially important if you have configured REMOTE_USER authentication. NAV's classic REMOTE_USER support has a lot of bells and whistles that Django's support lacks. We have added support for NAV's config options but it is a little used feature. There should be no need to update the confg file. (#3626) - Allow users to set a subscribed dashboard as their default (#3572) - Refactored dhcpstats backend. Users beware: option user_context_poolname_key in dhcpstats.conf renamed to user_context_groupname_key and its default value changed from name to group. (#3766) - Upgraded jQuery library to version 4 (#3730) - Upgraded Marionette to V4 in the IPAM tool (#1873) - Refactored dashboard navlets to use HTMX for rendering and updates (#3635) - Stopped CI testing on Python 3.12 by default (#3741) ## Fixed - Re-enabled sorting by actor in auditlog table, now actually working robustly! (#3581) - Fixed breadcrumbs missing from JWT Create and Edit frontend pages (#3682) - Fixed bug where Netmap views could not be created or updated (#3737) - Ensure that the auditlog entries for deleting accounts behave like other entries. (#3738) - Fixed IP Device select in Add New Service form (#3749) - Filtering on SeedDB Patch and Cable pages now searches all visible columns instead of only the jack field (#3760) - Popover arrow is now correctly positioned when aligned to the end (#3770) - Fix bug where Getting Started tour does not highlight the correct element (#3771) - PortAdmin's save feedback modal now appears instantly instead of being delayed by a network round-trip (#3772) - Add global CSRF token handlers for all HTMX and jQuery AJAX POST requests, to ensure things do not break unintentionally when CSRF validation is enabled - Fixed a crash in nav config where when no config file directory could be found ## Release notes We always advise you to have a look at NAV's accompanying release notes [3] before upgrading. Happy NAVing everyone! ## Links [1] https://github.com/Uninett/nav/releases [2] https://nav.uninett.no/install-instructions/#debian [3] https://nav.readthedocs.io/en/latest/release-notes.html#nav-5-17 -- Sincerely, Morten Brekkevold Sikt – Norwegian Agency for Shared Services in Education and Research
