LevelOne GSW-1290 Gigabit Layer2 SNMP Switch
Figure 4- 25. 802.1Q Port Settings and entries table
Configure the 802.1 Port Settings:
Parameter Description
Unit Select the relevant Switch for configuration.
From [ ] To [ ]
Use these drop-down menus to specify the range of ports that will be
included in the VLAN.
Ingress Check
This field can be toggled using the space bar between Enabled and
Disabled . Enabled enables the port to compare the VID tag of an
incoming packet with the PVID number assigned to the port. If the two are
different, the port filters (drops) the packet.
Disabled disables Ingress
filtering. Ingress Checking is disabled by default.
Frame Type
Allows you to specify the action the Switch will take when a packet is
received. If you specify
Admit_all the Switch will receive and forward all
packets to this VLAN regardless of whether or not the packet has an
802.1Q VLAN tag or not. If you specify
Tagged_only the Switch will drop
and untagged packets it receives for this VLAN.
PVID
A Port VLAN Identifier is a classification mechanism that associates a port
with a specific VLAN and is used to make forwarding decisions for
untagged packets received by the port. For example, if port 2 is assigned
a PVID of 3, then all untagged packets received on port 2 will be assigned
to VLAN 3. This number is generally the same as the VID number
assigned to the port in the Edit 802.1Q VLANs window above.
