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.
