5503.0. "PROBLEMS WITH SNMP COUNTERS" by DRAC::DSMAIL () Thu Aug 19 1993 05:22

	Hello;

	I am studing a network using DECmcc. 
    
	I have a router CISCO with SNMP.  I have customized an historial
	to get information about it performance. I notice that when the
	figures are not very big, the stadistic information is correct

		"Xmitd Octet + Rcvd Octet" = Total Octet

	but when the figures are bigger this is wrong, seem like if the counter
	of Total Octet, would has a maximun arround  43 E+06 , and after that
	it makes a reset and starts again, and I can't  get real information
	from the counters.
	  
	This are some dates from the CISCO:

                        *************************
                        CIEMGW_INTERFACE_SERIAL_3
                        *************************
           

		   Total          Rcvd           Xmitd          

                   Octet          Octet          Octet          Octet Rate

	Is this true ?

	Will the next version increase the size of this counter ?


	I am using:
	
		DECmcc 1.3 
		vms 5.5-2 
		cdd 5.1 
		rdb 4.2 
		decgraph 1.6a 
		dtr 6.0

	Thank in advance;
