6.2.7 FTP ALG Configuration
Most FTP servers allow the capability of listening on a non standard control port other than
TCP 21. When the policy associated with this non standard port is configured with the
application ftp qualifier, as configured in the solution to this recipe, it dynamically open the
pinholes for the data channel for such FTP sessions.

6.3 QoS
6.3.1 IP QoS
The DSL device provides a control mechanism that can provide different priority to different users
or data flows. The QoS is enforced by the QoS rules in the QoS table. A QoS rule contains two
configuration blocks: Traffic Classification and Action. The Traffic Classification enables you to
classify packets on the basis of various fields in the packet and perhaps the physical ingress port.
The Action enables you to assign the strict priority level and mark some fields in the packet that
matches the Traffic Classification rule. You can configure any or all field as needed in these two
QoS blocks for a QoS rule.
Fields on the first setting block of this page:
Field
Description
IP QoS
Enable/Disable the IP QoS function.
Source IP
The IP address of the traffic source.
Source Netmask
The source IP Netmask. This field is required if the source IP has been entered.
Destination IP
The IP address of the traffic destination.
Destination Netmask
The destination IP Netmask. This field is required if the destination IP has been
entered.
Protocol
The selections are TCP, UDP, ICMP and the blank for none. This field is required if
the source port or destination port has been entered.
