AIR INTERFACE FOR FIXED BROADBAND WIRELESS ACCESS SYSTEMS

IEEE Std 802.16-2001

5.2.6 IEEE Std 802.1Q-1998 VLAN specific part

This CS shall be employed when IEEE Std 802.1Q-1998 tagged VLAN frames are to be carried over the IEEE Std 802.16-2001 network.

5.2.6.1 IEEE Std 802.1Q-1998 VLAN CS PDU format

The format of the IEEE Std 802.1Q-1998 VLAN CS PDU shall be as shown in Figure 14.

5.2.6.2 IEEE Std 802.1Q-1998 CS classifiers

The following parameters are relevant for IEEE Std 802.1Q-1998 CS classifiers:

LC classification parameters—zero or more of the LLC classification parameters (Destination MAC address, source MAC address, Ethertype/SAP).

IEEE Std 802.1D-1998 Parameters—zero or more of the IEEE classification parameters (IEEE Std 802.1D-1998 Priority Range, IEEE Std 802.1Q-1998 VLAN ID).

For IP over IEEE Std 802.1Q-1998 VLAN, IP headers may be included in classification. In this case, the IP classification parameters (11.4.9.3.6.2—11.4.9.3.6.7) are allowed.

5.2.7 IP specific part

This subclause applies when IP (IETF RFC 791, IETF RFC 2460) is carried over the IEEE Std 802.16-2001 network.

5.2.7.1 IP CS PDU format

The format of the IP CS PDU shall be as shown in Figure 15 (when header suppression is not applied) or Figure 16 (with header suppression).
