12.3. SNMPv3 Setup
You can create an SNMPv3 user with "auth" and "priv" level security. A new user created will use the
already existing "initial" group and existing "internet" and "restricted" views, based on the security level
selected.
Use "snmp-server user" commands to create the users.
You can use MegaVision™ SNMPv3 features to communicate with the device. The passwords used in user
creation must be at least 8 characters long. SNMPv3 passwords are stored encrypted. The EM316LNXNM
MAC address (which is unique for every NM) is used to encrypt the passwords. For this reason, it is
required to recreate the SNMPv3 passwords when a configuration file containing SNMPv3 passwords is
moved form one NM to another NM.
Example: The following commands create some SNMPv3 users.
fiberdriver(config)# snmp-server user fdrNoAuth
fiberdriver(config)# snmp-server user fdrMd5Auth auth md5 open-sesame
fiberdriver(config)# snmp-server user fdrMd5Priv auth md5 open-sesame priv
des close-sesame
fiberdriver(config)# snmp-server user fdrShaAuth auth sha open-sesame
fiberdriver(config)# snmp-server user fdrShaPriv auth sha open-sesame priv
des close-sesame
fiberdriver(config)#
In the above commands, "
open-sesame
" and "
close-sesame
" are passwords and usernames start
with "fdr". This section assumes familiarity with SNMPv3 concepts.
12.4. SNMP Disable
Security conscious users can selectively enable or disable SNMP v1/v2c/v3 agents using either of the
following commands:
• "
snmp-server (v1|v2c|v3)
"
• "
no snmp-server (v1|v2c|v3)
"
