Define Policy Map

This procedure helps you define a policy map and associate it with traffic class you configured previously in
Define Class, on page 214
Purpose
• Type 3: match protocol {protocol-value |min-value -max-value}
• Type 4: Create two class-maps: one with source-port and another with
destination-port:
◦ match source-port {source-port-value |min-value -max-value}
◦ match destination-port {destination-port-value |min-value
-max-value}
Note
• Type 5: match destination-port {destination-port-value |[min-value -
max-value]}
• Type 6: match source-port {source-port-value |[min-value - max-value]}
• Type 7: match {ipv4}icmp-code {value |min-value -max-value}
• Type 8: match{ipv4}icmp-type {value |min-value -max-value}
• Type 9: match tcp-flag value bit-mask mask_value
• Type 10: matchpacket length {packet-length-value |min-value
-max-value}}
• Type 11: match dscp {dscp-value |min-value -max-value}
• Type 12: match fragment-type { is-fragment }
• Type 13: match ipv4 flow-label {value |min-value -max-value}
