Configuring an SM for the Destination Configuring for the Destination
310
pmp-0229 (Mar 2013)
In the VLAN tab of an SM, you may set the following parameters.
Always use Local VLAN Config
Enable this option before you reboot this AP as an SM to use it to perform spectrum analysis.
After the spectrum analysis is completed and before you reboot this module as an AP, disable this
option.
VLAN Port Type
By default this will be simply Q, indicating that it is to operate in the existing manner. The other
option is Q-in-Q, which indicates that it should be adding and removing the S-Tag, and adding a
C-Tag if necessary for untagged packets. The VLAN Port type corresponds to the Ethernet port of
the SM. Currently, the internal management interfaces will always operate as Q ports.
Accept QinQ Frames
This option is valid for the Q-in-Q port so that the user may force blocking of existing 802.1ad Q-
in-Q frames. This way, only untagged or single tagged packets will come in and out of the
Ethernet interface. If a Q-in-Q frame is about ingress or egress the Ethernet interface and this is
disabled, it will be dropped and a filter entry will show up on the VLAN Statistics page as
DVLAN Egress or DVLAN Ingress.
Dynamic Learning
Specify whether the SM should (Enable) or should not (Disable) add the VIDs of upstream
frames (that enter the SM through the wired Ethernet interface) to the VID table. The default value
is Enable.
Allow Frame Types
Select the type of arriving frames that the SM should tag, using the VID that is stored in the
Untagged Ingress VID parameter. The default value is All Frames.
VLAN Aging Timeout
Specify how long the SM should keep dynamically learned VIDs. The range of values is 5 to 1440
(minutes). The default value is 25 (minutes).
NOTE:
VIDs that you enter for the Untagged Ingress VID and Management VID
parameters do not time out.
