Identifier). In LLC encapsulation, the LLC header specifies the protocol being

Traffic shaping options for the CellPipes
The traffic shaping feature in the CellPipes allows you to specify the transmit rate and
priority for each VC you define. You specify traffic shaping by choosing a Service
Type and Service Rate for each connection profile. The Service Rate is the number of
cells/per second. The Service Type can be either “Unspecified” or “Constant.”
Specifying “Constant” means that the traffic will transmit at a pre-defined constant bit
rate. The default Service Type is “Unspecified” and the default Service Rate is “0.”
With this default, transmission will be based on a best effort method.
For example, you can set up a connection profile where the Service Type is
“Constant” and the Service Rate is 1000 cells/per second. You can set up a second
profile where the Service Type is also “Unspecified” but the service rate is set to 500
cells/per second.
Depending on the Encaps options you chose (ATM or PPP), you can specify the
Service Type and Service Rate from the Configure > Ethernet > Encaps options...
menu option or the Configure > Ethernet > Interface options... menu option.
Note:
If you are setting up multiple connection profiles and you specify the Service
Type as “Constant” for each profile, make sure the total Service Rate for the profiles
is less than or equal to the maximum upstream rate.
