ALFOplus 24GHz (North America) - Release 01.05.0x - MN.00395.E - 004 43
• IP: the priority is set based on the DSCP field of the either IPv4 or IPv6 (Native ToS/DSCP)
• Default: the priority is set in a static mode and its value is configurable based on the Entering LAN
interface. This Default configuration is a “Port Based” Priority with default priority value of 0 (lowest
priority). These priority values can be configured by the user within the range from 0 (lowest prior-
ity) up to 7 (higher priority). The Default mode is also used when all the other criteria are not ap-
plicable.
It is in addition possible to map the EXP quality of the MPLS label into the PCP field of the outer VLAN tag
(802.1p Rewrite with MPLS).
7.3.3 Ingress filtering policy (CIR/EIR according to MEF 10.2)
SIAE equipment allows limiting the ingress traffic rate on the basis of:
• LAN port (Bandwidth profile per UNI): a different profile is defined for each LAN port (VLAN ID and
priority are not considered in this case by the rate limiting algorithm)
• VLAN (Bandwidth profile per EVC): a different profile is defined for different VLANs (priority is not
considered in this case by the rate limiting algorithm). Up to 64 VLAN can be managed with different
profiles.
• VLAN + priority (Bandwidth profile per CoS): a different profile is defined for different couples
VLAN+priorities (up to 64 different cases can be managed). In this case the packet priority is always
considered by the rate limiting algorithm. More than one priority can be included in the same band-
width profile.
7.3.3.1 Not registered traffic default colour
Green (MEF Compliant)/Red policy
Refer to the Fig.13.
Fig.13 - Not registered traffic default colour
In case at least one CIR/EIR entry has been defined for filtering the traffic at a certain ingress port, the
user is allowed to specify the colour the not registered traffic has to marked with, i.e. all not registered
traffic could be marked as either “Green” or “Red” packets. In the latter case, the traffic will be immediately
discarded.
7.3.3.2 CIR/EIR configuration
In general different criteria can be defined for each port/VLAN/priority. Up to 64 Ingress Filtering Policy
resources can be defined and each bandwidth profile defined on the basis either of LAN port, VLAN or
VLAN+priority consumes 1 of such resources.
Basing on the above policies, it is possible to assign different traffic profiles (i.e. CIR/EIR profiles) to the
incoming Ethernet services.
