used to allow the interface port(s) to accept tagged or untagged frame.
-
all
: The port accepts all frames, tagged or untagged.
-
tagged
: The port accepts only tagged frames.
-
untagged
: The port accepts only untagged frames.
switchport allowed vlan [add x
|
remove x | forbidden add x | forbidden
remove x]
command will add the interface port(s) to VLAN x, remove the
interface port(s) from VLAN x, as forbidden port(s) to VLAV x, not forbidden
port(s) to VLAN x. “
x
” is the VLAN ID and its valid value is 2~-4094.
switchport ingressfilter
command is used to enable VLAN ingress filter
function on the ports. “
no switchport ingressfilter
“ command is used to
disable it.
switchport mode [c-port | s-custom-port | s-port | unaware]
command is
used to set Port Type of the ports. "Port Type" defines the port type in the
provider bridge(Q-in-Q) model. Customer VLAN has TPID == 0x8100 and
Service VLAN has TPID == 0x88A8. For the applications that there is no Q-
in-Q support, S-port and S-custom -port could be ignored.
-
c-port
: When a port is setup as C-port, tagged frames will be classified to
the VLAN based on this tag of the frames. This is for 802.1Q VLAN trunk.
-
s-custom-port
: When a port is setup as S-custom -port, the TPID in tag of
egress frame are always customized TPID as Service VLAN. This is for Q-
in-Q uplink connection.
-
s-port
: When a port is setup as S-port, the TPID in tag of egress frame are
always 0x88A8 as Service VLAN. This is for Q-in-Q uplink connection.
-
unaware
: When a port is setup as Unaware. Incoming frames will be
treated as untagged. Even when an incoming frame is tagged, this tag is
treated by the switch as payload. And the frame will be classified to port
based VLAN
— PVID. This for 802.1Q access connection or Q-in-Q downlink
connection. If Port-
based VLAN is used, please set ports as “Unaware” with
the same PVID.
switchport native vlan [none | x]
command is used to assign VLAN ID of the
native VLAN for classifying
untagged frames on ingress port. “
x
” is the port
VLAN ID (PVID) and its valid value is 1~4094. “
none
” is used when this is
VLAN trunk port.
When untagged packet is received, PVID of the ingress port will be used as
its working VLAN ID. PVID is also us ed as the VLAN ID for tag adding when
untagged packet is translated to tagged packet.
switchport tx_tag [tag_all | untag_all | untag_pvid]
command is used to
define how frame will be tagged on the egress direction -- when frame is sent
out of the switch from this port.
-
tag_all
: this is a tagged egress port. All egress packets are tagged.
-
untag_all
: this is a untagged egress port. All egress packets are
