After you’ve built a new storage environment you will probably want to monitor it and/or integrate the equipment in existing monitoring tools. SNMP is one of the protocols to use for this, but for some reason I always forget how to do a Cisco NX-OS SNMP v3 configuration. There’s a big difference in security between SNMP v2c and v3 and they’re configured quite differently: SNMPv2c uses community strings, SNMPv3 builds on the user accounts in the switch. This post will show you how to configure SNMP v3 in the DCNM SAN GUI and on the Cisco MDS NX-OS CLI.
Cisco Smart Zoning greatly reduces the time needed to zone servers to storage on Cisco NX-OS SAN switches. Instead of creating numerous zones that contain one single initiator and one single target, you can now classify a WWN as initiator, target or both and throw them all into one single zone. The switch then figures out which devices should be allowed to talk with each other (based on the parameter you set for each WWN). Not only does this speed up the entire zoning process but it also helps keep the zoning interface uncluttered and minimize the risk for errors. Let’s see how you can configure this in the DCNM-SAN GUI…
