Bandwidth Management
Parameters entered at Cisco StrataView Plus when adding connection. Bandwidth performance
monitored by viewing selected statistics at Cisco StrataView Plus NMS.
Bandwidth Efficiency
Since voice traffic is time sensitive, and low-speed voice connections can result in SGW cells being
sent with only a single packet placed in the cell in order to avoid excessive delay between cells. It
may be necessary to use the cnfcmb command on the interface shelves in order to configure the
packet combining timeout rate for a particular application.
Statistics
Enabled and monitored via Cisco StrataView Plus.
