SMG Digital Gateway

In factory configuration, switch ports may not access each other.
Device switch is equipped with 3x
1
or 4x
2
electrical Ethernet ports, 2x optical ports and 1x port for CPU
interactions:
GE port
— electrical Ethernet ports of the device.
SFP port
— optical Ethernet ports of the device.
CPU —
internal port linked to the device CPU.
Switch Settings
Enable VLAN
— when checked, enable 'Default VLAN ID', 'Override' and
'
Egress' settings for this
port.
Default VLAN ID
— when an untagged packet is received at the port, this will be its VID; when a
tagged packet is received at that port, its VID is considered to be specified in its VLAN tag.
VID override — when checked, it is considered that any received packet has a VID, defined in
'default VLAN ID'
row. True for both untagged and tagged packets.
Egress:
–
unmodified
— packets will be sent by the port without any changes (i.e. as they came to
another switch port).
–
untagged
— packets will always be sent without VLAN tag by this port.
–
tagged
— packets will always be sent with VLAN tag by this port.
–
double tag
— each packet will be sent with two VLAN tags — if received packet was
tagged and sent with one VLAN tag — if the received packet was untagged.
IEEE mode - sets security mode for received tagged frames processing.
