6.7.4 Configuration Examples for Classification and Queuing
Figure 6-6 Common Network with Cisco Router on page 6-20
an example of a Cisco router configuration.
This document provides a general description of VoIP technology, but it does not discuss individual
manufacturer solutions. This sample configuration is provided as a common scenario. It is a good example
of how QoS can be implemented on a router.
NEC does not endorse or provide support on any third party equipment unless it is supplied by NEC.

See Table 6-6 Cisco Router Configuration Example on page 6-21
the Cisco 2621 router. A description of key commands follows.
6-20
84-10-02 Priority – 0=Lowest ~ 7=Highest
(ToS bits: 0~2)
84-10-03 Delay – 0=Normal, 1=Low
(Tos Bit: 3)
84-10-04 Throughput – 0=Normal, 1=High
(Tos Bit: 4)
84-10-05 Reliability – 0=Normal, 1=High
(ToS Bit: 5)
ToS Bit 7: Always 0
Typically, only one of bits 3~6 is set to 1 and the other three bits are set to 0. For example,
to maximize route reliability, set 84-10-05 to 1 and leave 84-10-03, 84-10-04 and 84-10-06
at 0 (default).
84-10-07 DSCP Value in Decimals: 0~63
(ToS bits: 0~5)
ToS Bits 6 & 7 are not evaluated
