Overview of Installation and Configuration

How do Pri and ToS Override Affect My Inbound and Outbound frames?

How do Pri and ToS Override Affect My Inbound and Outbound frames?

Consider the following command.

lanadmin -V create vlanid VID pri PRI tos TOS pri_override PO tos_override TO 6

This command will create a VLAN interface on PPA 6, with VID as the VLAN ID, PRI as the 802.1p priority, TOS as the IPv4 ToS value.

•All frames transmitted via the newly created interface will be VLAN tagged.

•The VLAN ID field in the tag will be VID without exception.

•Please note that non-IP packets are not affected by PO, TO, and TOS settings. Outbound non-IP packets are always tagged with VLAN ID VID and 802.1p priority PRI.

The following information applies only to inbound and outbound IP traffic.

•The 802.1p priority value in the VLAN tag is determined by the PRI, PO, and TOS settings as shown in Table 2-4.

•The ToS value of an inbound IP packet header is determined by TOS, TO, and PRI settings as shown in Table 2-5.
