Follow this procedure to configure SNMPv3, which supports Ethernet switch health monitoring (CSHM).
The following commands configure an SNMPv3 username on Broadcom BES-53248 switches:
-
For no authentication:
snmp-server user SNMPv3UserNoAuth NETWORK-OPERATOR noauth -
For MD5/SHA authentication:
snmp-server user SNMPv3UserAuth NETWORK-OPERATOR [auth-md5|auth-sha] -
For MD5/SHA authentication with AES/DES encryption:
snmp-server user SNMPv3UserAuthEncrypt NETWORK-OPERATOR [auth-md5|auth-sha] [priv-aes128|priv-des]
The following command configures an SNMPv3 username on the ONTAP side:
cluster1::*> security login create -user-or-group-name SNMPv3_USER -application snmp -authentication-method usm -remote-switch-ipaddress ADDRESS
The following command establishes the SNMPv3 username with CSHM:
cluster1::*> system switch ethernet modify -device DEVICE -snmp-version SNMPv3 -community-or-username SNMPv3_USER
-
Set up the SNMPv3 user on the switch to use authentication and encryption:
show snmp statusShow example
(sw1)(Config)# snmp-server user <username> network-admin auth-md5 <password> priv-aes128 <password> (cs1)(Config)# show snmp user snmp Name Group Name Auth Priv Meth Meth Remote Engine ID ----------------- ------------------ ---- ------ ------------------------- <username> network-admin MD5 AES128 8000113d03d8c497710bee -
Set up the SNMPv3 user on the ONTAP side:
security login create -user-or-group-name <username> -application snmp -authentication-method usm -remote-switch-ipaddress 10.231.80.212Show example
cluster1::*> security login create -user-or-group-name <username> -application snmp -authentication-method usm -remote-switch-ipaddress 10.231.80.212 Enter the authoritative entity's EngineID [remote EngineID]: Which authentication protocol do you want to choose (none, md5, sha, sha2-256) [none]: md5 Enter the authentication protocol password (minimum 8 characters long): Enter the authentication protocol password again: Which privacy protocol do you want to choose (none, des, aes128) [none]: aes128 Enter privacy protocol password (minimum 8 characters long): Enter privacy protocol password again:

Configure CSHM to monitor with the new SNMPv3 user:
system switch ethernet show-all -device "sw1" -instanceShow example
cluster1::*> system switch ethernet show-all -device "sw1 (b8:59:9f:09:7c:22)" -instance Device Name: sw1 IP Address: 10.228.136.24 SNMP Version: SNMPv2c Is Discovered: true DEPRECATED-Community String or SNMPv3 Username: - Community String or SNMPv3 Username: cshm1! Model Number: BES-53248 Switch Network: cluster-network Software Version: 3.9.0.2 Reason For Not Monitoring: None <---- should display this if SNMP settings are valid Source Of Switch Version: CDP/ISDP Is Monitored ?: true Serial Number of the Device: QTFCU3826001C RCF Version: v1.8X2 for Cluster/HA/RDMA cluster1::*> cluster1::*> system switch ethernet modify -device "sw1" -snmp-version SNMPv3 -community-or-username <username> -
Verify that the serial number to be queried with the newly created SNMPv3 user is the same as detailed in the previous step after the CSHM polling period has completed.
