To. . .
• Replace the existing DSCP of
packets with a DSCP of 12 for all
traffic that has a source IP address of
199.93.238.83.
• Mask the three least significant bits
of the DSCP.
Replace the existing DSCP of the
packet with a DSCP of 24 for all
ICMP traffic that has a:
• Source IP address of 2.2.2.2
• Destination IP address of 4.4.4.4
Assign a priority of 6 to all TCP traffic
that has a:
• Source IP address in the 10.10.10
subnet
• Destination IP address in the
11.11.11 subnet
• Destination port of 1
Use the layer 2 priority in the packet
to classify all UDP traffic
• Use the layer 2 priority in the packet
to classify all TCP traffic that has a:
— Source IP address in the 5.5.5
subnet
— Destination IP address in the
6.6.6 subnet
— Destination port that is less
than 2
• Permit TCP connections that meet
this criteria
