Canopy System User Guide Configuring an SM for the Destination
pmp-0229 (Mar 2013)
311
Management VID
Enter the VID that the SM should share with the AP. The range of values is 1 to 4095. The default
value is 1.
SM Management VID Pass-through
Specify whether to allow the SM (Enable) or the AP (Disable) to control the VLAN settings of
this SM. The default value is Enable.
When VLAN is enabled in the AP to whom this SM is registered, the Active Configuration block
provides the following details as read-only information in this tab. In the Cambium fixed wireless
broadband IP network, each device of any type is automatically a permanent member of VID 1.
This facilitates deployment of devices that have VLAN enabled with those that do not.
Default Port VID
This is the VID that will be used for untagged frames and will correspond to the Q-Tag for 802.1Q
frames (if VLAN Port Type is Q), or the C-Tag for 802.1ad frames (if the VLAN Port Type is Q-
in- Q).
Port VID MAC Address Mapping
These parameters allow operators to place specific devices onto different VLANs (802.1Q tag or
802.1ad C-tag) based on the source MAC address of the packet. If the MAC address entry is 00-
00-00-00-00-00 then that entry is not used. If a packet arrives at the SM that is sourced from a
device whose MAC address is in the table, then the corresponding VID will be used for that
frame’s Q-tag (Q port) or C-tag (Q-in-Q port). If there is no match, then the Default Port VID will
be used. This table is also used in the downstream direction for removal of the tag based on the
destination MAC address so that an untagged (for Q port) or Q-Tagged (for Q-in-Q port) frame is
delivered to the end device. You may use wildcards for the non-OUI (Organizationally Unique
Identifier) portion of the MAC address, which is the last 3 bytes. MAC addresses contain 6 bytes,
the first 3 of which are the OUI of the vendor that manufactured the device and the last 3 are
unique to that vendor OUI. If you want to cover all devices from a known vendor’s OUI, you
would specify 0xFF for the remaining 3 bytes. So, for example, if you wanted all devices from a
specific vendor with an OUI of 00-95-5b (which is a Netgear OUI) to be on the same VID of 800,
you would specify an entry with MAC address 00-95-5b-ff-ff-ff. Then, any device underneath of
the SM with MAC addresses starting with 00-95-5b will be put on VLAN 800.
Provider VID
The provider VID is used for the S-tag. It is only used if the Port Type is Q-in-Q and will always
be used for the S-tag. If an existing 802.1Q frame arrives, the Provider VID is what will be used
for adding and removing of the outer S-tag. If an untagged frame arrives to a Q-in-Q port, then
the Provider VID will be the S-tag and the Default Port VID (or Port VID MAC Address
Mapping, if valid) will be used for the C-tag.
