Obtain a tree of information from a network device using automatic SNMP GETNEXT commands. In NetMRI’s administrative shell version of the snmpwalk command, you can specify the SNMP version, the community string, and the desired Root Object ID (OID).
For SNMP v3, you can additionally specify the encryption protocol from the following:
- aes-128
- aes-192
- aes-192C (for Cisco devices only)
- aes-256
- aes-256C (for Cisco devices only)
- des
- 3des
Syntax
The following is the command syntax:
snmpwalk 22
Example
The command prompts for further information before executing (if only one network view exists in the NetMRI appliance, you will not be prompted to enter that value):
SA4-17> snmpwalk
Enter SNMP hostname or IP address []: 172.19.4.192
Enter Network View []: MGMT
Enter SNMP version (1, 2c, 3) [2c]: 3
Enter SNMP Username [ ]: aes_username
SNMP Authentication [no]: yes
Enter SNMP Authentication Passphrase [ ]: my_passwd
Enter SNMP Authentication Protocol [MD5]: sha
SNMP Privacy [no]: yes
Enter SNMP Privacy Passphrase [ ]: my_aes_passwd
Enter SNMP Privacy Protocol [DES]: aes-256
Enter Root OID to start walk [system]:
Use legacy snmpwalk tool [n]:
