| 207 | | === Adding MIBs === |
| 208 | | |
| 209 | | Remember when you ran: |
| 210 | | |
| 211 | | $ snmpwalk <IP Address> .1.3.6.1.4.1.9.9.13.1 |
| 212 | | If you noticed, the SNMP client (snmpwalk) couldn't interpret all the OIDs coming back from the Agent: |
| 213 | | |
| 214 | | SNMPv2-SMI::enterprises.9.9.13.1.3.1.2.1 = STRING: "chassis" |
| 215 | | SNMPv2-SMI::enterprises.9.9.13.1.3.1.6.1 = INTEGER: 1 |
| 216 | | What is 9.9.13.1.3.1 ? |
| 217 | | |
| 218 | | To be able to interpret this information, we need to download extra MIBs: |
| 219 | | |
| 220 | | Download them now as follows: |
| 221 | | {{{ |
| 222 | | $ cd /usr/share/mibs |
| 223 | | $ sudo mkdir cisco |
| 224 | | $ cd cisco |
| 225 | | |
| 226 | | $ sudo wget http://www.ws.nsrc.org/downloads/mibs/CISCO-SMI.my |
| 227 | | $ sudo wget http://www.ws.nsrc.org/downloads/mibs/CISCO-ENVMON-MIB.my |
| 228 | | }}} |
| 229 | | |
| 230 | | Now we need to tell the snmp tools that we have the cisco MIBS it should load. So edit the file /etc/snmp/snmp.conf, and add the following two lines: |
| 231 | | {{{ |
| 232 | | mibdirs +/usr/share/mibs/cisco |
| 233 | | mibs +CISCO-ENVMON-MIB:CISCO-SMI |
| 234 | | }}} |
| 235 | | Save the file, quit. |
| 236 | | |
| 237 | | Now, try again: |
| 238 | | |
| 239 | | $ snmpwalk <IP Address> .1.3.6.1.4.1.9.9.13.1 |
