More to the point, cfgmaker blithely reports whatever the host claims as it's speed from either the ifSpeed or the ifHCSpeed OID. If you manually walk the switch, do you get sensible values in those two slots? > > That said, you MUST use version 2 SNMP counters as Steve suggested in > order to graph anything over 110mpbs in a 5-minute span. If the correct value is not in ifSpeed, cfgmaker will not check ifHCSpeed unless you are running snmp v2 or v3. -- Daniel J McDonald, CCIE #2495, CISSP #78281, CNX Austin Energy http://www.austinenergy.com
