Low Priority TX Tag Assignment (Memory Block 1-16-09)
For frames marked at the ingress port by Memory Block 1-16-06 as Low
Priority, this memory block setting on the egress port assigns a value (0 ~7) to
the priority field of the VLAN tag. The default is 0.
Port Mirroring Selection (Memory Block 1-16-10)
Use this Memory Block to specify whether or not Port Mirroring is enabled for
each HUB(8)-U( ) ETU. The source port and the target port must be members
of the same VLAN(s).
Mirroring Source Port Assignment (Memory Block 1-16-11)
When Port Mirroring is enabled in Memory Block 1-16-10 (Port Mirroring
Selection), use this Memory Block to specify a port with data to be monitored
on another port specified by Memory Block 1-16-12 (Mirroring Target Port
Assignment) for each HUB(8) -U( ) ETU. The source port and target port
must be in the same VLAN(s).
Mirroring Target Port Assignment (Memory Block 1-16-12)
When Port Mirroring is enabled in Memory Block 1-16-10 (Port Mirroring
Selection), use this Memory Block to specify a target port that monitors frames
transmitted on the source port specified by Memory Block 1-16-11 (Mirroring
Source Port Assignment) for each HUB(8) -U( ) ETU. The source port and
target port must be in the same VLAN(s).
VLAN Group to VLAN ID Assignment (Memory Block 1-16-13)
Use this Memory Block to create a list of valid VLAN IDs to be recognized by
the HUB(8)-U( ) ETU.
Port VLAN Group Membership (Memory Block 1-16-14)
Use this Memory Block to create a list of accepted VLANs for each port.
When Memory Block 1-16-04 (VLAN Mode Selection) is set to YS, each port
accepts frames tagged with VLAN IDs only when the port is programmed as a
member of that VLAN Group. Frames without VLAN tags are also permitted.
When Port Mirroring is used, the source and target ports must be members of
the same VLAN(s).
VLAN Tag Insertion Selection (Memory Block 1-16-15)
Use this Memory Block to specify whether or not the port should insert VLAN
tags in frames transmitted on this port. When this Memory Block is set to NO,
tags are deleted from frames of the same VLAN Group transmitted on this
port.
