7.2 LOOPS
To control the equipment correct operation a set of local and remote loops are made available. The com-
mands are forwarded by the WEBLCT program. The available loop facilities are:
• Line Loop (Ethernet Port Loop)
• Baseband loop
• RF loop (only for GB8xxxx)

7.3 RATE LIMITING AND INGRESS FILTER POLICING
7.3.1 Rate limiting
In SIAE equipment it is possible to apply the Rate Limit, i.e. to limit the total rate passing through an in-
terface. It is possible to apply the rate limiting from 64 kbit/s up to the maximum port speed (up to 1GE).
The values that can be inserted are pre-fixed from 64 kbit up to 10Mbit (64Kb, 128kb, 256kb, 512kb, 1Mb,
2Mb, 3Mb, 4Mb, 5Mb, 6Mb, 7Mb, 8Mb and 9Mb), In the range from 10Mbit/s up to 1Gbit/s the limiting val-
ues can be chosen by the user with a 10Mbit/s step. i.e. the minimum selectable granularity is 10Mb/s.
7.3.2 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.
