Regardless of terminal width FS switches always split known VLAN ranges into multiple lines of at most twenty numbers when showing configuration. Do the same in our config template to avoid reporting changes when there are none. Allowed VLANs for tagged ports are displayed similarly but even worse, with the first line specifying `allowed vlan only` for the first twenty numbers and subsequent lines adding the remaining VLANs. Not sure if configuring a switch this way – as opposed to a single long `allowed vlan only` line – could disrupt traffic. Instead we simply allow all VLANs on uplink ports, marked in NetBox as 'tagged-all'. For downlink tagged ports the number of allowed VLANs is unlikely to exceed twenty. Ansible now reports no fictional changes for all existing access switches. The only remaining issue is removing known VLANs, which has to be done manually on each switch. |
