As far as I can tell the only way to identify a device for a static lease on MikroTik is by MAC address? The ‘use src MAC address’ option I believe uses the Remote ID information but it still needs to be entered into the ‘MAC Address’ field of a static lease, meaning it can only accept standard MAC address format, not something like "SwitchA.0/1’
Is there a code to be able to enter standard or other text into the MAC field? i.e. 0x[HEX FORMAT] or some other escape character that would let something other than a MAC address be entered for identification
