Configuring Protocol Conditions with Parameters (SRC CLI)

Use the following configuration statements to configure classify-traffic conditions that contain a parameter value for the protocol:

policies group name list name rule name traffic-condition name parameter-protocol-condition {protocol protocol ; protocol-operation protocol-operation ; tcp-flags tcp-flags ; tcp-flags-mask tcp-flags-mask ; spi spi ; ip-flags ip-flags ; ip-flags-mask ip-flags-mask ; fragment-offset fragment-offset ; packet-length packet-length ; }
policies group name list name rule name traffic-condition name parameter-protocol-condition proto-attr {icmp-type icmp-type ; icmp-code icmp-code ; igmp-type igmp-type ; }
policies group name list name rule name traffic-condition name parameter-protocol-condition proto-attr destination-port port {port-operation port-operation ; from-port from-port ; }
policies group name list name rule name traffic-condition name parameter-protocol-condition proto-attr source-port port {port-operation port-operation ; from-port from-port ; }

To configure a protocol condition that contains a parameter value for the protocol:

  1. From configuration mode, enter the parameter protocol condition configuration. For example:
    user@host# edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition
  2. Assign a parameter as the protocol matched by this classify-traffic condition.

    Before you assign a parameter, you must create a parameter of type protocol and commit the parameter configuration.

    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition]user@host# set protocol protocol
  3. (Optional) Configure the policy to match packets with the protocol that is either equal or not equal to the specified protocol.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition]user@host# set protocol-operation protocol-operation
  4. (Optional) Configure the value of the TCP flags field in the IP header.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition]user@host# set tcp-flags tcp-flags
  5. (Optional) Configure the mask associated with TCP flags.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition]user@host# set tcp-flags-mask tcp-flags-mask
  6. (Optional) Specify the authentication header (AH) or the encapsulating security payload (ESP) security parameter index (SPI).
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition]user@host# set spi spi
  7. (Optional) Configure the value of the IP flags field in the IP header.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition]user@host# set ip-flags ip-flags
  8. (Optional) Configure the mask that is associated with the IP flag.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition]user@host# set ip-flags-mask ip-flags-mask
  9. (Optional) Configure the value of the fragment offset field.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition]user@host# set fragment-offset fragment-offset
  10. (Optional) Configure the packet length on which to match. The length refers only to the IP packet, including the packet header, and does not include any layer 2 encapsulation overhead.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition]user@host# set packet-length packet-length
  11. (Optional) Enter the protocol attribute configuration.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition]user@host# edit proto-attr
  12. (Optional) Configure the ICMP packet type.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition proto-attr]user@host# set icmp-type icmp-type
  13. (Optional) Configure the ICMP code.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition proto-attr]user@host# set icmp-code icmp-code
  14. (Optional) Configure the IGMP packet type on which to match.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition proto-attr]user@host# set igmp-type igmp-type
  15. (Optional) Enter the destination port configuration.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition proto-attr]user@host# edit destination-port port
  16. (Optional) Configure the policy to match packets with a port that is either equal or not equal to the specified port.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition proto-attr destination-port port]user@host# set port-operation port-operation
  17. (Optional) Configure the TCP or UDP destination port.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition proto-attr destination-port port]user@host# set from-port from-port
  18. (Optional) Enter the source port configuration.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition proto-attr destination-port port]user@host# up [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc param-proto-condition proto-attr]user@host# edit source-port port
  19. (Optional) Configure the policy to match packets with a port that is either equal or not equal to the specified port.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition proto-attr source-port port]user@host# set port-operation port-operation
  20. (Optional) Configure the TCP or UDP source port.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition proto-attr source-port port]user@host# set from-port from-port [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition proto-attr source-port port]user@host# up [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition proto-attr source-port]user@host# up [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition proto-attr]user@host# up [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition]user@host# up
  21. (Optional) Verify the parameter protocol configuration.
    [edit policies group junose list dhcp rule forward-dhcp traffic-condition ctc parameter-protocol-condition]
    user@host# show 
    protocol protocol;
    protocol-operation is;
    tcp-flags 0;
    tcp-flags-mask 0;
    ip-flags 0;
    ip-flags-mask 0;
    proto-attr {
      icmp-type 255;
      icmp-code 255;
      destination-port {
        port {
          port-operation eq;
          from-port outsidePort;
        }
      }
    }
