Operating notes on using TCP/UDP port ranges
-
Only 6 concurrent policies are possible when using unique ranges. The number of policies allowed is less if ACLs are also using port ranges.
-
No ranges allowed that include any port numbers configured as part of another QoS application port number policy.
-
An error message is generated if there are not enough hardware resources available when configuring a policy.
-
The entire range of configured port numbers must be specified when using the
noform of the command, for example:switch(config)# qos udp-port range 1300 1399 dscp 001110 switch(config)# no qos range 1300 1399
Configuration for TCP and UDP port prioritization
The following example displays the following configuration for TCP and UDP port prioritization:
|
TCP/UDP port |
802.1p priority for TCP |
802.1p priority for UDP |
|---|---|---|
|
TCP Port 23 (Telnet) |
7 |

|
UDP Port 23 (Telnet) |
