[comp.dcom.sys.cisco] SNMP problem?

Hello,
	I have been using SNMP to grab output statistics so that
I can find the utilization of a serial line. Last Tue. I got the
following two numbers for output bytes:


Tue Jun 18 15:13:14 1991 
_mgmt_mib_interfaces_ifTable_ifEntry_ifOutOctets_2	0xf361395f	4083235167

Tue Jun 18 15:33:14 1991 
_mgmt_mib_interfaces_ifTable_ifEntry_ifOutOctets_2	0xf4c1ca52	4106340946

Which works out to 23105779 Octets in 1200 seconds. Which means that
on average, this link was passing :

4106340946-4083235167 = 23105779 Octets
23105779*8 bits per octet = 184846232 bits
184846232/1200 seconds = 154038 bps

Truly amazing for a 128kb circuit!

Has anybody else seen suspect numbers from a Cisco? The configuration is?
