[SM4] QoS Technology in NP-SM4 Switches

QoS technology in NP-SM4 switches is programmed to provide a good result for the most scenarios with default
settings.

Amount of queues in the interface:4

Queues servicing mechanism:WRR (Weighted Round Robin)

Traffic classification: by six high-order IP TOS and IPv6 TC bits

Classification table:

Queque number

Beginning of the Range

End of the Range

0

0x00

0x0f

1

0x10

0x1f

2

0x20

0x2f

3

0x30

0x3f

Queque 3 has the biggest weight, queque 0 – the least one.

Make sure that IP-phones mark voice traffic with DSCP values, which correspond to queques 2 or 3 to ensure a
prioritization of a voice traffic.
