View
System view
Parameter
dialer-number: Number of the dialer access group, corresponding to the parameter
group-number in the dialer-group group number command in DCC interface view. The
argument ranges from 1 to 255.
protocol-name: Network protocol such as IP, IPX, bridge.
permit: Permits the packets of the specified protocol.
deny: Denies the packets of the specified protocol.
acl acl-number: Number of the access control list to which the access control group
corresponds.
Description
Use the dialer-rule command to configure the conditions of the data packet that can
trigger a DCC call.
Use the undo dialer-rule command to cancel the setting.
By default, no conditions of packet-triggering DCC calls are set for dial interfaces.
This command is used to set the DCC call packet-triggering control to which an access
control group corresponds. And a dial interface can be placed in an access control
group through the dialer-group command. Thereby, the DCC call’s packet-triggering
on the DCC interface can be controlled.
If an access control group cannot find the corresponding dialer-rule, DCC will regard
the packets as packets which do not comply with the “permit” conditions in ACL rule and
just drop them. No DCC call will be originated.
Related command: dialer-group.
Example
# Set a dialer-rule.
