TOS service allows users to achieve QoS on IP network.

---------------------------------------------------------------

usr/config$ tos

IP Packet ToS(type of Service)/Differentiated Service configuration Usage:

tos [-rtptype dscp] tos [-sigtype dscp] tos -print

[-rtpreliab mode] tos -print

Example:

tos -rtptype 7 -sigtype 0

---------------------------------------------------------------

In QoS, a modification of the type of service byte. Six bits of this byte are being reallocated for use as the DSCP field, where each DSCP specifies a particular per-hop behavior that is applied to a packet. Support for DSCP still is lacking in some network equipment, please refer to RFC 2474

Note:

1.The value of rtptype and sigtype is from 0 to 63.

2.Users should be aware that TOS is effective only when network devices (for ex: router, switch.. etc.) support TOS.
