You can send packets marked with ip TOS using extended
ping:

router1#ping
Protocol [ip]:
Target IP address: 10.20.20.200
Repeat count [5]:
Datagram size [100]:
Timeout in seconds [2]:
Extended commands [n]: y
Source address or interface: 10.10.10.101
Type of service [0]: 5
Set DF bit in IP header? [no]:
Validate reply data? [no]:
Data pattern [0xABCD]:
Loose, Strict, Record, Timestamp, Verbose[none]:
Sweep range of sizes [n]:
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.20.20.200,
timeout is 2 seconds:
