Specifying Dsu Bandwidth - Cisco 10000 Series Configuration Manual

Chapter 15 8-Port Unchannelized E3/T3 Line Card Configuration

Specifying DSU Bandwidth

Use the dsu bandwidth command to specify the full-rate or subrate bandwidth for an E3 or T3 interface
using the following format:
dsu bandwidth bandwidth
[no] bandwidth
Where:
•
•
Use the no form of this command to return to the full-rate default values.
In the following example, the full-rate bandwidth for an E3 interface is set to 34368:
Router(config)# interface serial 2/0/0
Router(config-if)# dsu bandwidth 34368
Creating a Subrate E3 or T3 Interface
You can create a subrate E3 or T3 controller interface by specifying a bandwidth value that is less than
full-rate for the near end DSU.
In the following example, the subrate dsu bandwidth for a T3 interface is set to 16000:
Router(config)# interface serial 4/0/6
Router(config-if)# dsu mode cisco
Router(config-if)# dsu bandwidth 16000
When you specify a bandwidth, the software sets that bandwidth to the closest acceptable bandwidth
Note
value based on the time-slot size for the current DSU mode. See the
E3 or T3 Interface"
Encapsulation Command
Use the encapsulation command to specify the type of encapsulation for the interface using the
following format:
encapsulation encapsulation-type
Where encapsulation-type is:
•
•
•
The default encapsulation is hldc.
The following example sets the encapsulation type as ppp:
Router(config)# interface serial 4/0/6
Router(config-if)# encapsulation ppp
OL-8834-04
bandwidth = 0 to 44210 kbps for a T3 interface
The default value for a T3 interface is 44210 (full-rate)
–
bandwidth = 0 to 34368 kbps for an E3 interface
The default value for an E3 interface is 34368 (full-rate)
