Replace Cisco Nexus 3132Q-V cluster switches

Contributors netapp-aoife netapp-martyh

You must be aware of certain configuration information, port connections and cabling requirements when you replace Cisco Nexus 3132Q-V cluster switches.

  • The Cisco Nexus 3132Q-V cluster switch is supported.

  • The number of 10 GbE and 40/100 GbE ports are defined in the reference configuration files (RCFs) available on the Cisco® Cluster Network Switch Reference Configuration File Download page.

  • The cluster switches use the Inter-Switch Link (ISL) ports e1/31-32.

  • The Hardware Universe contains information about supported cabling to Nexus 3132Q-V switches:

    • The nodes with 10 GbE cluster connections require QSFP optical modules with breakout fiber cables or QSFP to SFP+ copper break-out cables.

    • The nodes with 40/100 GbE cluster connections require supported QSFP/QSFP28 optical modules with fiber cables or QSFP/QSFP28 copper direct-attach cables.

    • The cluster switches use the appropriate ISL cabling: 2x QSFP28 fiber or copper direct-attach cables.

  • On Nexus 3132Q-V, you can operate QSFP ports as either 40/100 Gb Ethernet or 4 x10 Gb Ethernet modes.

    By default, there are 32 ports in the 40/100 Gb Ethernet mode. These 40 Gb Ethernet ports are numbered in a 2-tuple naming convention. For example, the second 40 Gb Ethernet port is numbered as 1/2. The process of changing the configuration from 40 Gb Ethernet to 10 Gb Ethernet is called breakout and the process of changing the configuration from 10 Gb Ethernet to 40 Gb Ethernet is called breakin. When you break out a 40/100 Gb Ethernet port into 10 Gb Ethernet ports, the resulting ports are numbered using a 3-tuple naming convention. For example, the breakout ports of the second 40/100 Gb Ethernet port are numbered as 1/2/1, 1/2/2, 1/2/3, 1/2/4.

  • On the left side of Nexus 3132Q-V is a set of four SFP+ ports multiplexed to the first QSFP port.

    By default, the RCF is structured to use the first QSFP port.

    You can make four SFP+ ports active instead of a QSFP port for Nexus 3132Q-V by using the hardware profile front portmode sfp-plus command. Similarly, you can reset Nexus 3132Q-V to use a QSFP port instead of four SFP+ ports by using the hardware profile front portmode qsfp command.

  • You must have configured some of the ports on Nexus 3132Q-V to run at 10 GbE or 40/100 GbE.

    You can break-out the first six ports into 4x10 GbE mode by using the interface breakout module 1 port 1-6 map 10g-4x command. Similarly, you can regroup the first six QSFP+ ports from breakout configuration by using the no interface breakout module 1 port 1-6 map 10g-4x command.

  • You must have done the planning, migration, and read the required documentation on 10 GbE and 40/100 GbE connectivity from nodes to Nexus 3132Q-V cluster switches.

    The Cisco Ethernet Switches page has information about the ONTAP and NX-OS versions supported in this procedure.
