Atu Setup - RACOM RAy3 User Manual

5.5.4.4. ATU setup

The Address Translation Unit (ATU) in the device supports user commands to access the contents of
the MAC address database.
There is one static record which cannot be deleted. This is the management CPU record. The unicast
frames directed to management are allowed to access the CPU port. The "VLAN tunnel" parameter is
also used to enable the AP frames to access the CPU port.

• FID
Forwarding Information Database number. If multiple address databases are not being used, this
parameter must remain zero. If multiple address databases are being used, this parameter is used
to set the desired address database number that is to be associated with this ATU Entry's MAC Ad-
dress. When frames ingress the switch, the VID assigned to the frame is used to access the VTU.
The VTU returns the FID associated with that VID for MAC address lookups in to the ATU.
• MAC
MAC address associated with this ATU entry in the database number defined by the FID.
• Label
A custom string label for a STU entry.
• Entry state
The Entry state parameter is used to determine the entry's age or its type as follows:
○ static — Use for ordinary static entry.
○ static policy — Use for "Policy DA" and/or "Policy SA" (menu Advanced/Monitoring/Policy).
○ static non rate limiting — Use for "SA non rate limit" and/or "DA non rate limit" (menu Interface/PIRL).
○ static management — This value is used for the mapping of the DA even if the "DA mapping"
parameter is disabled (menu Advanced/ATU settings).
