SRW2024 port utilization OID/MIB

Hi


Now when going into webview in this switch, under statistics-> Port Utlization you see a % for every port ,

now that is the value i want but i cannot find the MIB/OID to use to get that value. I believe there is none

that port utlization is a calculation  of possibly a number of OID's to get that value, but what does linksys

use to achieve that. Looking at google for port utilization calculations comes up with the following:


The purpose of knowing utilization is to know whether a link in the network is overloaded. Thus, the bar graph for a port shows utilization for the busiest half-link (Rx or Tx) on the port. For example, using a port configured for 100Mbps, full-duplex, if the port was transmitting at 35% utilization on one half-link and receiving at 10% on the other half-link, the port would show a 35% utilization.

Utilization is calculated by the formula

utilization % = (data bits x 100) / (bandwidth x interval)

Thus, on a 10Mbps half-duplex port, a 3-second measurement of 6,000,000 bits would indicate a 20% utilization of the port.


So am i right do we have to find OID for every bit in the above calculation  if so are they all available. It would be much

simpler for me to have one OID to did this so that i could put together in MRTG.


thanks

Hi cchospital,


Do a search on this site for ' mib srw'  and i believe a couple of my colleagues have  suggested a couple of approaches you can use.

Great.

This mibs also apply just fine for SPS series.

To test them with net-snmp (linux, bsd, etc):

download and unpack to some directory (i.e. srw_mib)

cd srw_mibs

snmpwalk -v2c -M +. -c .
