In the exhibits, what is the reason for the tail drops in queue 0?
A.
The interface cannot physically handle 3.37 Gbps of traffic.
B.
The default network-control scheduler is taking bandwidth from the best-effort scheduler.
C.
The default queue 0 scheduler does not allocate enough buffer size for 3.37 Gbps of traffic.
D.
The default queue 0 scheduler does not allocate enough transmit rate for 3.37 Gbps of traffic.
Explanation:
How is this determined?
Te answer is C because the device uses the default scheduler settings:
[edit class-of-service]
schedulers {
network-control {
transmit-rate percent 5;
buffer-size percent 5;
priority low;
drop-profile-map loss-priority any protocol any drop-profile terminal;
}
best-effort {
transmit-rate percent 95;
buffer-size percent 95;
priority low;
drop-profile-map loss-priority any protocol any drop-profile terminal;
}
}
drop-profiles {
terminal {
fill-level 100 drop-probability 100;
}
}
the default scheduler that BE have 95% buffer-size
Why is not enough for 3.37G?
3618165696/1024/1024/1024 = 3.369 Gbps or as listed approx 3.37Gbps
