* When using the ifName or ifDescr as means to map discovered ports to
|
|
* known ports in the DB (think of port association mode) it's possible
|
|
* that we're facing the problem that the ifName or ifDescr polled from
|
|
* the device is unset or an empty string (like when querying some ubnt
|
|
* devices...). If this happends we have no way to map this port to any
|
|
* port found in the database. As reported this situation may occur for
|
|
* the time of one poll and might resolve automagically before the next
|
|
* poller run happens. Without this special case this would lead to new
|
|
* ports added to the database each time this situation occurs. To give
|
|
* the user the choice between »a lot of new ports« and »some poll runs
|
|
* are missed but ports stay stable« the 'ignore_unmapable_port' option
|
|
* has been added to configure this behaviour. To skip the port in this
|
|
* loop is sufficient as the next loop is looping only over ports found
|
|
* in the database and "maps back". As we did not add a new port to the
|
|
* DB here, there's no port to be mapped to.
|
|
*
|
|
* I'm using the in_array() check here, as I'm not sure if an "ifIndex"
|
|
* can be legally set to 0, which would yield True when checking if the
|
|
* value is empty().
