The switch port is disabled and it will not receive or transmit any
frames. disabled
The switch examines all frames, learning source addresses (SA)
from all good frames (except those from MGMT frames) and re-
ceives and transmits all frames as a normal switch. forwarding
Only MGMT frames are allowed to enter (ingress) or leave (egress)
a Blocked port. All other frame types are discarded. Learning is
disabled on Blocked ports. blocking
Only MGMT frames are allowed to enter (ingress) of leave (egress)
a Learning port. All other frame types are discarded but learning learning
takes place on all good non-MGMT frames that are not discarded
owing to being filtered.
Frame mode
Ethernet Frame mode control defines the expected Ingress and the generated
Egress tagging frame format for this port as follows:
Normal Network mode uses industry standard IEEE 802.ac Tagged
or Untagged frames. Tagged frames use an Ether Type of 0x8100. normal
Ports that are expected to be connected to standard Ethernet
devices should use this mode.
Inactive options are not required. DSA
Provider mode uses user definable Ether Types per port (see
Ether type parameter) to define that a frame is Provider Tagged. provider
Ports that are connected to standard Provider network devices,
or devices that use Tagged frames with an Ether Type other than
0x8100 should use this mode.
Frames that ingress this port with an Ether Type that matches the
port's
Ether Type parameter will be considered tagged, will have
the tag's VID and PRI bits assigned to the frame (i.e. they will be
used for switching and mapping), and will have the Provider Tag
removed from the frame. If subsequent Provider Tags are found
following the 1st Provider Tag, they too will be removed from the
frame with their VID and PRI bits being ignored. Modified frames
will be padded if required.
Frames that ingress this port with an Ether Type that does not
match the
Ether Type parameter will be considered untagged. The
ingressing frames are modified so they are ready to egress out
Customer ports (Normal Network Frame Mode ports) unmodified.
Frames that egress this port will always have a tag added (even
if they were already tagged). The added tag will contain this port's
Ether Type as its Ether Type. The PRI bits will be the Frame Priority
assigned to the frame during ingress. The VID bits will be the
source port's Default VID bits (if the source port was in Normal
Network mode), or the VID assigned to the frame during ingress
(if the source port was in Provider mode).
Inactive options are not required. ether type

MTU [B]
MTU determines the maximum frame size allowed to be received or transmitted
from or to a given physical port. This implies that a Jumbo frame may be allowed
