BreezeNET DS.11 Series User Manual

3-10

♦ Filtering/Forwarding packets received on the BU’s Ethernet port:

 The unit accepts from the Ethernet port only data frames with a destination

on the Wireless port side (an associated RB).

 If the destination RB is configured as Hybrid port (VLAN ID = 65535), both

tagged and untagged data packets will be forwarded to the RB without any

change.

 If the destination RB is configured as Access port, only data packets with a

matching VLAN ID will be forwarded. The VLAN tag is removed. All other

data frames (with a non-matching VLAN ID or with no VLAN tag) are not

accepted.

♦ Filtering/Forwarding packets received on the BU’s Wireless port:

 If the source RB is configured as Hybrid port, all data packet are forwarded

to the bridging mechanism.

 If the source RB is configured as Access port, data packets with a VLAN tag

are dropped. Data packets without VLAN are forwarded to the bridging

mechanism with the VLAN ID and VLAN Priority of the source RB.

 Data packets that were forwarded to the bridging mechanism, whose

destination is on the Ethernet port, are forwarded to the Ethernet port

without any change.

 Data packets that were forwarded to the bridging mechanism, whose

destination is an RB on the wireless port side that is configured as Hybrid

port, are forwarded to the Wireless port without any change.

 A data packet that was forwarded to the bridging mechanism, whose

destination is an RB on the wireless port side that is configured as Access

port, is forwarded to the wireless port only if it is tagged with a VLAN ID

that matches the VLAN ID configured for the destination RB. The VLAN tag

is removed.

NOTE:

Because of the rules above it is possible that some broadcast packets will be transmitted twice on the

wireless port: Once with a VLAN tag and another time without VLAN. This may happen when the

broadcast packet has a VLAN tag, some of the destination RBs are configured as Hybrid ports and

some of the destination RBs are configured as Access ports with a VLAN ID that matches the VLAN ID

of the broadcast packet.
