Dimension
Step 4. Then the switch applies the port filter to finish the forwarding decision. This means that frames may be dropped even if the SVLAN says to forward them. Frames might also be dropped if they are sent to a CPE (customer premises equipment) DSL device that does not accept tagged frames.
Untagged Frames
Step 1. An untagged frame comes in from the LAN.
Step 2. The switch checks the PVID table and assigns a temporary VID of 1.
Step 3. The switch ignores the port from which the frame came, because the switch does not send a frame to the port from which it came. The switch also does not forward frames to “forbidden” ports.
Step 4. If after looking at the SVLAN, the switch does not have any ports to which it will send the frame, it won’t check the port filter.
23.4.12VLAN1Q SVLAN Delentry Command
Syntax:
ras> sys sw vlan1q svlan delentry <VID>
where
<VID> = The VLAN ID [1 – 4094].
This command deletes the specified VLAN ID entry from the static VLAN table The following example deletes entry 2 in the static VLAN table.
ras> sys sw vlan1q svlan delentry 2
