Setting the Type of Service

The type of service (ToS) for an IP packet determines how the network handles
the packet and balances its precedence, throughput, delay, reliability, and cost.
This information resides in the IP header. To set the ToS for packets in a particular
traffic class, use the set ip tos command in parameter map connection
configuration mode. The syntax of this command is as follows:
set ip tos number
Use the number argument to replace a packet's ToS byte value with the specified
value. Enter an integer from 0 to 255. For details about the ToS byte, see
RFCs 791, 1122, 1349, and 3168.
For example, to set a packet's ToS byte value to 20, enter:
host1/C1(config-parammap)# set ip tos 20
To reset the ACE behavior to the default of not rewriting the ToS byte value of an
incoming packet, enter:
host1/C1(config-parammap)# no set ip tos 20
