Smart Ma5600T Ntp Time Problem Caused Synchronized Time Abnormally - Huawei MA5600 Manual

NGN Cases
3. Further check the parameters and commands related to the board and find that the
PIR value set for the traffic profile is very small. This may be the root cause of the packet
loss and the poor multicast quality:
//Configure the VCI33 VPI1 multicast service
igmp user add port 0/1/21 adsl 1 33 video 1 33 no-auth quickleave immediate
//The traffic profile of VCI33 VPI1 is rx 9 tx 15
service-port 103 vlan 401 adsl 0/1/21 vpi 1 vci 33 single-service rx-cttr 9 tx-cttr 15
//Settings of the traffic profile
traffic table ip index 9 cir 2944 cbs 96208 pir 3968 pbs 192416 priority 6 priority-policy
local-setting
traffic table ip index 15 cir 384 cbs 14288 pir 768 pbs 28576 priority 6 priority-policy
local-setting
The pri value of the profile in traffic-table 9 is 3968 kbps = 3968*1024 = 4063232 bps =
507904 byte/s.
//Check on the LSW the number of frames that pass the port in the downstream direction
each second:
BCM.0> show c
......
Omitted
GRMCA.ge7 : 10,243,109 +426,416 390/s
Omitted
......
Here, 390/s is the number of frames that pass this GE port in the downstream direction
each second. If each fragment is calculated as 1410 bytes, we can figure out:
390 * 1410 byte = 549900 byte/s > 507904 byte/s. Thus, a large number of packets are
lost.
Handling Proces
It is suggested that the onsite engineer modify the settings to enlarge the traffic profile.
