Configuring Protocol Conditions with Ports
Use the following configuration statements
to add general protocol conditions with ports to a classify-traffic
condition:
- policies group name list name rule name traffic-condition name protocol-port-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 ;
- }
- policies group name list name rule name traffic-condition name protocol-port-condition
destination-port port {
- port-operation port-operation ;
- from-port from-port ;
- }
- policies group name list name rule name traffic-condition name protocol-port-condition
source-port port {
- port-operation port-operation ;
- from-port from-port ;
- }
To add general protocol conditions with
ports to a classify-traffic condition:
- From configuration mode, enter the protocol port condition
configuration. For example:
- user@host# edit policies group junos list
bodVpn rule pr traffic-condition ctc protocol-port-condition
- Configure the protocol matched by this classify-traffic
condition.
- [edit policies group junos list bodVpn rule pr traffic-condition
ctc protocol-port-condition]
- user@host# set protocol protocol
- Configure the policy to match packets with the protocol
that is either equal or not equal to the specified protocol.
- [edit policies group junos list bodVpn rule pr traffic-condition
ctc protocol-port-condition]
- user@host# set protocol-operation protocol-operation
- (Optional) Configure the value of the IP flags field in
the IP header.
- [edit policies group junos list bodVpn rule pr traffic-condition
ctc protocol-port-condition]
- user@host# set ip-flags ip-flags
- (Optional) Configure the mask that is associated with
the IP flag.
- [edit policies group junos list bodVpn rule pr traffic-condition
ctc protocol-port-condition]
- user@host# set ip-flags-mask ip-flags-mask
- (Optional) Configure the value of the fragment offset
field.
- [edit policies group junos list bodVpn rule pr traffic-condition
ctc protocol-port-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 junos list bodVpn rule pr traffic-condition
ctc protocol-port-condition
- user@host# set packet-length packet-length
- (Optional) Enter the destination port configuration for
the protocol port configuration.
- [edit policies group junos list bodVpn rule pr traffic-condition
ctc protocol-port-condition]
- user@host# edit destination-port
- (Optional) Configure the policy to match packets with
a port that is either equal or not equal to the specified port.
- [edit policies group junos list bodVpn rule pr traffic-condition
ctc protocol-port-condition destination-port port]
- user@host# set port-operation port-operation
- (Optional) Configure the destination port.
- [edit policies group junos list bodVpn rule pr traffic-condition
ctc protocol-port-condition destination-port port]
- user@host# set from-port from-port
- (Optional) Enter the source port configuration for the
protocol port configuration.
- user@host# up
- [edit policies group junos list bodVpn rule pr traffic-condition
ctc protocol-port-condition]
- user@host# edit source-port
- (Optional) Configure the policy to match packets with
a port that is either equal or not equal to the specified port.
- [edit policies group junos list bodVpn rule pr traffic-condition
ctc protocol-port-condition source-port port]
- user@host# set port-operation port-operation
- (Optional) Configure the source port.
- [edit policies group junos list bodVpn rule pr traffic-condition
ctc protocol-port-condition source-port port]
- user@host# set from-port from-port
- [edit policies group junos list bodVpn rule pr traffic-condition
ctc protocol-port-condition source-port port]
- user@host# up
- (Optional) Verify your protocol condition configuration.
[edit policies group junos list bodVpn rule pr traffic-condition ctc protocol-port-condition]
user@host# show
protocol 17;
protocol-operation 1;
ip-flags ipFlags;
ip-flags-mask ipFlagsMask;
fragment-offset ipFragOffset;
packet-length packetLength;
destination-port {
port {
port-operation eq;
from-port service_port;
}
}
source-port {
port {
port-operation eq;
from-port service_port;
}
}
