dsu bandwidth
For T3 controllers only
This command specifies the peak allowable bandwidth used by the T3/E3 port. DSU bandwidth
configuration must match the remote configuration and it is important that you know the
bandwidth value set on the remote port. For example, if you reduce the bandwidth to 7,000 kbps
on the local port, you must do the same on the remote port. This command reduces bandwidth by
padding the T3/E3 frame.
For E3 ports in bypass framing mode, DSU bandwidth defaults to 34,368 kbps.
Even though the XSR lets you configure a continuous range of bandwidths in sub‐rate modes,
vendors support bandwidths only in certain values. So, the XSR sets the user‐configured
bandwidth to the closest vendor‐supported bandwidth (refer to
) and a message
displayed showing the new bandwidth. Use the
show controller
command to view the
vendor‐supported bandwidth the XSR sets.
Syntax
dsu bandwidth bandwidth
Syntax of the “no” Form
The no form of this command sets the DSU bandwidth to the default:
no dsu bandwidth
Note: DSU bandwidth is configurable only for an unchannelized T3/E3 port.
