Rate + User Tagged Mode

Features:

•No Network port learning

•User port learning is based on MAC

•TDMoIP & Managers traffic must be tagged.

Table 1-11. Rate+User Tagged Mode

Frame Action	Switch Action
A tagged frame enters the Network port	Switched to User port without changing the
	frame***
A tagged frame enters the User port
Both User and Network ports are members of	Switched to Network port without changing the
frames’s VLAN	frame*
	Subject to rate limiting
Either the User or Network port is not a	Discarded
member of frames’s VLAN
An untagged frame enters the Network port	Switched to User port without changing the
	frame***
An untagged frame enters the User port**	Discarded

Note	*	The switch may decide not to pass the frame to the other port, based on its
		learning.
	**	A priority-tagged frame (frame with a tag and VLAN-ID 0) is treated just like an
		untagged frame. This includes rewriting the priority field with 0.
	***	Learning is disabled; therefore, every frame is switched. The network port is
		typically connected to another switch.

Rate + User Untagged Mode

Features:

•Network port learning is based on MAC + VLAN number

•User port learning is based on MAC + VLAN number

•TDMoIP & Managers traffic must be tagged.
