Not recieving the full bandwitch on T!

Unanswered Question
Oct 14th, 2008

Upgraded Frac T1 from 768 to full T1 1544.Sub interface shows 768k.The main interface shows 1536. Any suggestions on how to verify actual bandwidth so I can go back to the Telco Provider and make them fix? Thanks in advance.

Hi,

rxload 245/255 already shows leaking is reaching to peak utilization.

Also clear the counter and see input rate & output rate, that will also give you fair idea,about throughput you are getting on this link

In addition you can use client-server application like "iperf" to test the bandwidth.

Jperf is the GUI for iperf.

HTH...rate if helpful..

you consider the actual bandwidth on the main serial interface (s0/3/0). you may want to configure bandwidth on the sub interface (s0/3/0.1) and monitor bandwidth via a network monitoring tool or using show interface command.
