some of those numbers weird. like:
Interface Se1/0
Access Target Byte Sustain Excess Interval Increment Adapt
VC List Rate Limit bits/int bits/int (ms) (bytes)
Active
- 48000 1992 7968 7968 166 996
R6(config-if)#traff rate 56000
R6(config-if)#do sh traff
Interface Se1/0
Access Target Byte Sustain Excess Interval Increment Adapt
VC List Rate Limit bits/int bits/int (ms) (bytes)
Active
- 56000 1988 7952 7952 142 994 -
and some others...Where does it get the byte limit and TC for these?
48000/32 = 1500.
