12.4Configuration Example 3: Port Range Using ACL or Policy

Assuming we wish to filter on the following port ranges and remark the traffic to CoS level shown below:

•TCP dst-port 80-127 with CoS level of Gold

•UDP dst-port 2000-2047 with CoS level of Silver

As mentioned in section 3.3, a port range must start with an even minimum number while the maximum number rightmost consecutive 0’s are replaced with 1’s. The table shown below displays the valid ranges that can be configured.

Table 9: Port Range
