[ixpmanager] some questions re: IXP 5

[Athanasios Douitsis]

Hello everyone,

We (GR-IX) have a few questions regarding the upgrade from an existing
4.8 installation to version 5.2.

- We have setup the latest BirdsEye in our route servers and have
  successfully integrated with a test 5.2 installation. The looking
  glass in our 5.2 installation detects prefixes that are being
  filtered, by examining their BGP large community. All good as far as
  we can tell. However, when we look at the "filtered prefixes" tab in
  any member's page, we see no filtered prefixes. Can we inquire as to
  which exactly is the interdependency between what is seen in the
  looking glass and what is seen in the per-member "filtered prefixes"
  tab? How do we get to see (if possible) the filtered prefixes in the
  tab?
- Does the update-l2database.pl script still stand as the way to fill in
  the dynamic mac addresses in the macaddresses table?  The
  https://docs.ixpmanager.org/usage/switches/#automated-polling-snmp-updates
  and the https://docs.ixpmanager.org/features/cronjobs/ pages do not
  mention it, but https://docs.ixpmanager.org/features/layer2-addresses/
  does mention it. Running it periodically certainly does not cause
  trouble.
- Going from 4.8 to 5.2 using the artisan subcommands to bring the
  database up to date, does not create the telescope-related tables.
  What is the recommended way to create them?
- Likewise, how is the cache table (if one chooses to use a database
  cache instead of files or memcached) supposed to be created and
  initialized?
- This is a trifling matter, but the field last_updated in the routers
  table will be left NULL if going from 4.8 to 5.2, which will cause a
  5xx error in the application. We are not sure this is mentioned
  explicitly in any documentation page.

If any of the above has been asked again, my apologies for the
duplicate. Any help with any item will be highly appreciated.

Kind regards,
