Polarity reverse (polrvs)
1 = polarity is reversed.
0 = polarity is not reversed.
MDIX Status (mdix_st)
1 = MDI
0 = MDI-X
Force Link (force_lnk)
1 = force link pass.
0 = normal operation.
Power Saving (pwrsave)
1 = disable power saving.
0 = enable power saving.
Remote (Near-End) Loopback (rlb)
1 = perform remote loopback at Port 2's PHY(RXP2/RXM2 ->
TXP2/TXM2. see Figure 15)
0 = normal operation

Broadcast Storm Protection Enable
1 = enable broadcast storm protection for ingress packets on the port.
0 = disable broadcast storm protection.
Diffserv Priority Classification Enable
1= enable DiffServ priority classification for ingress packets on the port.
0 = disable DiffServ function.
802.1p Priority Classification Enable
1= enable 802.1p priority classification for ingress packets on the port.
0 = disable 802.1p.
Port-Based Priority Classification
00 - ingress packets on port are classified as priority 0 queue if “DiffServ” or “802.1p” classification
is not enabled or fails to classify.
01 - ingress packets on port are classified as priority 1 queue if “DiffServ” or “802.1p” classification
is not enabled or fails to classify.
10 - ingress packets on port are classified as priority 2 queue if “DiffServ” or “802.1p” classification
is not enabled or fails to classify.
11 - ingress packets on port are classified as priority 3 queue if “Diffserv” or “802.1p” classification is
not enabled or fails to classify.
Note: “DiffServ”, “802.1p” and port priority can be enabled at the same time. The OR’ed result of
802.1p and DSCP overwrites the port priority.
Tag Insertion
1 = when packets are output on the port, the switch adds 802.1p/q tags to packets without 802.1p/q
tags when received. The switch will not add tags to packets already tagged. The tag inserted is the
ingress port’s “port VID”.
0 = disable tag insertion.
