9. Click Next. In the QoS Flow Types panel that appears, specify whether you want to
apply the flow to specific IP interfaces. Selecting No applies the flow to all IP
interfaces. Selecting Yes allows you to apply the flow to specific IP interfaces.
Source Mask Enter the network mask for which you are assigning a priority.
You can specify the mask using the traditional IP address
format (“255.255.0.0”). If you want to use the Classless Inter-
Domain Routing (CIDR) format
(“/16”), you may do so as discussed in the SmartSwitch Router
Command Line Interface Reference Manual.
If you specify ANY instead of a network mask, the SSR
assumes a wildcard “don’t care” condition. If you do not
specify a mask, then the SSR assumes a mask of
255.255.255.255. You cannot substitute the mask by entering
ANY. The option ANY is for the entire Source Address and
Source Mask pair.
Destination Mask Enter the destination network mask for which you are
assigning a priority. The same requirements and restrictions
for Source Mask apply to Destination Mask.
If you specify ANY instead of a network mask, the SSR
assumes a wildcard “don’t care” condition. If you do not
specify a mask, then the SSR assumes a mask of
255.255.255.255. You cannot substitute the mask by entering
ANY. The option ANY is for the entire Destination Address
and Destination Mask pair.
Type of Service Enter the TOS for which you are assigning a priority. Specify a
number from 0 to 15, or enter ANY to allow any value.
Protocol Enter the transport layer protocol (TCP or UDP) for which you
are assigning priority. If you specify ANY, priority is assigned
for both TCP and UDP.
