Why MA5600T cannot manage Upstream QoS ?
OLT version: V800R007C00SPC304+ HP0009
The traffic discarded for Upstream overload doesn't follow configured QoS rules.
We set 11 different upstream traffic streams.
2x Priority 5
2x Priority 4
2x Priority 2
5x Priority 0
Each traffic is 96Mbps full duplex
Each stream is configured on a different OPFA port.
The traffic analysis shows a 10% of loss on all streams.
The expected results is to have packet loss only on Streams marked with priority 0
The system is not able to mark priority correctly on Stacking VLAN architectures that adopt outer ethertype forced to 88a8
traffic table ip index 1010 name "Cos_to_Tos" cir off priority user-cos 0 priority-policy tag-in-package
traffic table ip index 1011 name "Tos_to_Cos" cir off priority user-tos 0 inner-priority user-tos 0 priority-policy tag-in-package
Service port example:
service-port 0 vlan 1002 eth 0/1/0 multi-service user-vlan 1035 tag-transform translate-and-add inner-vlan 100 inbound traffic-table index 1011 outbound traffic-table index 1010
1:1 Cos Queue Mapping. 1 different queue for each priority
Queue uses Strict Priority
