Issue/Introduction

For interface bandwidth, you can use the MIB attributes listed in RFC1213 MIB as PacketShaper does not have a special OID created for interfaces.
 
 Input utilization =                     ^ifInOctetsx8x100
                        -----------------------------------
                        (number of seconds in ^)x IfSpeed
 
 Output utilization =            ^ifOutOctetsx8x100
                      -----------------------------------
                      (number of seconds in ^)x IfSpeed
 
 [^ refers to Delta] Because MIB-II variables are stored as counters, it is necessary to take two poll cycles and figure the difference between the two, hence, the delta used in the equation.

 .1.3.6.1.2.1.2.2.1.16,x      ifOutOctets
 .1.3.6.1.2.1.2.2.1.5.x        IfSpeed
 
 X refer to the number of interfaces for the unit.
