NE05 cannot Normally Allocate PVC Bandwidth because of Configuration Fault

Publication Date:  2012-07-27 Views:  45 Downloads:  0
Issue Description
When configuring some PVC bandwidth resource of NE05, it prompts error.
Alarm Information
NE05(config-atm-pvc-Atm4/1/0.64-8/166)#vbr-nrt 1000 2000 512 
% Illogical VC service parameters
NE05(config-atm-pvc-Atm4/1/0.64-8/166)#vbr-nrt 2000 2000 512 
% No enough bandwidth available
Handling Process
Change peak rate 2000 as small to optimize configuration.
Root Cause
Actual bandwidth is not enough, so there is indication. The total bandwidth of the interface is 155M. Other PVC has occupied parts of bandwidth. When configuring PVC, the bandwidth is not enough. Check configuration and there have been 63 PVC. Each one configures 2M and occupies 126M. Although physical interface bandwidth is 155M, actual supporting bandwidth is about 120-130M because there is other overhead. When configuring the 64th PVC, the bandwidth is not enough.
Suggestions
Null
