This article shows two ways to do a v3 SNMPwalk from the AMP command line.
In AirWave 6.2 and later you can use the s3w alias:
# s3w <AMP_device_ID> [optional_OID]
To get the AMP_device_ID, go to the AMP web GUI and bring up a page for the device you want to walk (its Monitor page, for example). Look at the end of the URL for the page, you will see id=.. The number after id= is the AMP_device_ID.
This command uses the credentials that are configured in AirWave for that device.
The command defaults to walking the sysName OID if no other OID is provided.
Prior to AirWave 6.2 you will need to use the longer version:
# snmpwalk -v3 -u <v3 user> -A <auth pw> -a md5 -l AuthPriv -X <prviacy pw> <ip.address.of.controller> <OID>
# snmpwalk -v3 -u ampuser -A '<pwd>' -a sha -l AuthPriv -X '<pwd>' -x [des|aes] <ip.address.of.controller> <OID>
