Task 2: Configuring IP and Ethernet interfaces
VLAN Priority Bits configuration
VLAN Priority Bits Configuration feature allows the user to configure the three 802.1p
bits upon
assigning VLAN to an ingress packet. The priority bits configuration is
available for:
Default Port VID
Provider VID
MAC Address mapped Port VID
Management VID
Default Port VID
This VID is 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 QinQ).
The priority bits used in the Q-tag/C-tag are configurable. The configuration can be:
Promote IPv4/IPv6 priorityThe priority in the IP header is copied to the Q-
tag/C-tag.
Define prioritySpecify the priority in the range of 0 to 7. This value is used as
priority in the Q-tag/C-tag.
MAC Address Mapped VID
If a packet arrives at the SM that is sourced from a device whose MAC address is in the
table, then the corresponding VID is used for that frame’s Q-tag (Q port) or C-tag (QinQ
port). The priority bits used in the Q-tag/C-tag are configurable similar to default port
VID.
Provider VID
The provider VID is used for the S-tag. The priority bits used in the S-tag are
configurable similar to default port VID. Provider VID has an extra priority
configuration:
Copy inner tag 802.1p priorityThe priority in the C-tag is copied to the S-tag.
Management VID
This VID is used to communicate with AP and SM for management
purposes. The priority bits used in the Q-tag are configurable similar
to default port VID.
