Symptom

For cat9200L the interval to update interface counter relaated OIDs is more than 5 sec. If we poll within a 5 sec interval we will see the same value: ade # snmpwalk -v 2c -c ww 10.48.74.85 .1.3.6.1.2.1.31.1.1.1.6.65 IF-MIB::ifHCInOctets.65 = Counter64: 401762 ade # snmpwalk -v 2c -c ww 10.48.74.85 .1.3.6.1.2.1.31.1.1.1.6.65 IF-MIB::ifHCInOctets.65 = Counter64: 401938 ade # snmpwalk -v 2c -c ww 10.48.74.85 .1.3.6.1.2.1.31.1.1.1.6.65 IF-MIB::ifHCInOctets.65 = Counter64: 401938 ade # snmpwalk -v 2c -c ww 10.48.74.85 .1.3.6.1.2.1.31.1.1.1.6.65 IF-MIB::ifHCInOctets.65 = Counter64: 401938 ade # snmpwalk -v 2c -c ww 10.48.74.85 .1.3.6.1.2.1.31.1.1.1.6.65 IF-MIB::ifHCInOctets.65 = Counter64: 401938 ade # snmpwalk -v 2c -c ww 10.48.74.85 .1.3.6.1.2.1.31.1.1.1.6.65 IF-MIB::ifHCInOctets.65 = Counter64: 401938 ade # snmpwalk -v 2c -c ww 10.48.74.85 .1.3.6.1.2.1.31.1.1.1.6.65 IF-MIB::ifHCInOctets.65 = Counter64: 403136
