snmp monitoring[OT]

[Atul Gosain]

Sir

snmpwalk -c public my.ip  .1.3.6.1.4.1.9.9.13.1

I tried this ,but could not get more than this
SNMPv2-SMI::enterprises.9.9.13.1.1.0 = INTEGER: 6
SNMPv2-SMI::enterprises.9.9.13.1.3.1.2.1 = STRING: "chassis"
SNMPv2-SMI::enterprises.9.9.13.1.3.1.6.1 = INTEGER: 1
SNMPv2-SMI::enterprises.9.9.13.1.5.1.2.1 = STRING: "Internal Power Supply"
SNMPv2-SMI::enterprises.9.9.13.1.5.1.3.1 = INTEGER: 1
SNMPv2-SMI::enterprises.9.9.13.1.5.1.4.1 = INTEGER: 3

Does this output means that environmental monitoring is enabled on my 
cisco. (Allthough i dont think so )

Im monitoring cisco 2610, cisco 3620, cisco 5300

Thanks
Atul
