mrtg configuration
Hi all,
1. Does anyone know how to configure mrtg to exclude monitoring some interfaces on the switch? My switches have 24 ports, I want mrtg to monitor only fastethernet 0/1interfaces on every swicth. I do not want to see on web page all the interfaces (24) of all switches (32) :cry:

You can edit mrtg configuration file to remove all unwanted interfaces. Each config starts with Interface 1, Interface 2 etc. For example here is line for interace # 4 on 192.168.1.254 (just remove all following line
 :Code:
Target[192.168.1.254_4]: 4:public@192.168.1.254: SetEnv[192.168.1.254_4]: MRTG_INT_IP="" MRTG_INT_DESCR="nas0" MaxBytes[192.168.1.254_4]: 1250000 Title[192.168.1.254_4]: Traffic Analysis for 4 -- PageTop[192.168.1.254_4]: <H1>Traffic Analysis for 4 -- </H1> <TABLE> <TR><TD>System:</TD> <TD> in </TD></TR> <TR><TD>Maintainer:</TD> <TD></TD></TR> <TR><TD>Description:</TD><TD>nas0 </TD></TR> <TR><TD>ifType:</TD> <TD>ethernetCsmacd (6)</TD></TR> <TR><TD>ifName:</TD> <TD></TD></TR> <TR><TD>Max Speed:</TD> <TD>1250.0 kBytes/s</TD></TR> </TABLE>

First find out the OIDs used by Cisco for CPU and Memoey. You can get list from ftp.cisco.com.
Then locate CPU related OID and test it using nmpwalk command: Code:
snmpwalk -v1 -c public SWITCH-IP OID-TO-POLL-CPU-INFO Code:
Target[16-CPU]: 1.3.6.1.4.1.9.2.1.57.0&1.3.6.1.4.1.9.2.1.57.0:public@172.16.1.222 MaxBytes[16-CPU]: 100 Title[16-CPU]: Router CPU Load PageTop[16-CPU]: <h1>Router CPU Load </h1> Unscaled[16-CPU]: ymwd YLegend[16-CPU]: Utilization % ShortLegend[16-CPU]: % LegendI[16-CPU]: CPU LegendO[16-CPU]: Options[16-CPU]: gauge,growright
