Then what is mean by Byte limit and excess bits?? 2)The second output show queue depth = 3 what is the unit?? 3)Take a look on the access-list below(last one)- why they config "permit tcp any eq 102 any" in access-list 102?? can explain?? sin03#sh traffic serial 1/2 Interface Se1/2 Access Target Byte Sustain Excess Interval Increment Adapt VC List Rate Limit bits/int bits/int (ms) (bytes) Active - 102 64000 2000 8000 8000 125 1000 - sin03#sh traffic stat Access Queue Packets Bytes Packets Bytes Shaping I/F List Depth Delayed Delayed Active Se1/2 102 3 60581 50604741 37238 42926132 yes sin03#sh access-list Extended IP access list 102 permit tcp any eq smtp any permit tcp any eq 102 any (2270216 matches) permit tcp any any eq 102 (7253461 matches) permit tcp any any eq smtp _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
