when I run a snmpwalk, I get many error lines before the actual requested datas.
Example:
snmpwalk -v3 -u public 192.168.0.20 IF-MIB::ifHighSpeed

I use a very simple setup :
sudo apt-get install snmp
sudo apt-get install snmp-mibs-downloader
sudo gedit /etc/snmp/snmp.conf
( I comment out the 'mibs :' line )
sudo download-mibs
( I download the device MIBs, extract it and CD in )
sudo cp -R * /usr/share/snmp/mibs/
sudo bash -c 'echo "mibs ALL" >> /etc/snmp/snmp.conf'
Why do I get all these error lines ? If it's casual and unavoidable, is there a way to have them skipped from report? ( snmpwalk -Pe doesn't skipped them, ie : snmpwalk -Pe -v3 -u public 192.168.0.20 IF-MIB::ifHighSpeed )
