80-Series QoS
Assign a priority of 2 to all TCP traffic
that has a:
• Source IP address in the 1.1 subnet
• Source port that is greater than 24
• Destination IP address in the 6.6
subnet
• Destination port of 23
access-list MyAccessList2 3 permit
use-priority 2 tcp 1.1.0.0 0.0.255.255
gt 24 6.6.0.0 0.0.255.255 eq 23
• 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.
access-list MyAccessList2 4 permit
remark l2 mask ip host
199.93.238.83 any
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
access-list MyAccessList2 5 permit
remark 24 icmp host 2.2.2.2 host
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 su b net
• Destination port of 1
access-list MyAccessList2 6 permit
use-priority 6 tcp 10.10.10.0
0.0.0.255 11.11.11.0 0.0.0.255 eq 1
Use the layer 2 priority in the packet
to classify all UDP traffic access-list MyAccessList2 7 permit
use-l2 udp any any
• 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
access-list MyAccessList2 8 permit
use-l2 tcp 5.5.5.0 0.0.0.255 6.6.6.0
0.0.0.255 lt 2 established
