Configuring ICMP Conditions (SRC CLI)
Use the following configuration statements to add ICMP conditions to a classify-traffic condition:
policies group name list name rule name traffic-condition name icmp-condition
{protocol protocol ; protocol-operation protocol-operation ; ip-flags ip-flags ; ip-flags-mask ip-flags-mask ; fragment-offset fragment-offset ; packet-length packet-length ;icmp-type icmp-type ; icmp-code icmp-code ; }
Because the protocol is already set to ICMP, do not change the protocol or protocol-operation options.
To add ICMP conditions to a classify-traffic condition:
- From configuration mode, enter the ICMP configuration.
For example: user@host# edit policies group bod list input rule pr traffic-condition ctc icmp-condition
- (Optional) Configure the value of the IP flags field in
the IP header.[edit policies group bod list input rule pr traffic-condition ctc icmp-condition]user@host# set ip-flags ip-flags
- (Optional) Configure the mask that is associated with
the IP flag.[edit policies group bod list input rule pr traffic-condition ctc icmp-condition]user@host# set ip-flags-mask ip-flags-mask
- (Optional) Configure the value of the fragment offset
field. [edit policies group bod list input rule pr traffic-condition ctc icmp-condition]user@host# set fragment-offset fragment-offset
- (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 bod list input rule pr traffic-condition ctc icmp-condition]user@host# set packet-length packet-length
- (Optional) Configure the ICMP packet type on which to
match. The packet type must be supported by the router or CMTS device. [edit policies group bod list input rule pr traffic-condition ctc icmp-condition]user@host# set icmp-type icmp-type
- (Optional) Configure the ICMP code on which to match.
The ICMP code must be supported by the router or CMTS device. [edit policies group bod list input rule pr traffic-condition ctc icmp-condition]user@host# set icmp-code icmp-code
- (Optional) Verify the ICMP condition configuration.
[edit policies group bod list input rule pr traffic-condition ctc icmp-condition] user@host# show protocol icmp; protocol-operation 1; ip-flags ipFlags; ip-flags-mask ipFlagsMask; fragment-offset ipFragOffset; icmp-type icmpType; icmp-code icmpCode;
