Custom NVUE Configuration Snippets

Netris allows administrators to deploy custom configuration to switches running Cumulus Linux using NVUE configuration snippets. These snippets are YAML files that define specific configurations to be applied to the network devices.

Example:

  1. Stage desired configuration using NVUE commands

nv set system snmp-server state enabled
nv set system snmp-server listening-address all vrf mgmt
nv set system snmp-server listening-address all-v6 vrf mgmt
nv set system snmp-server readonly-community clear_text access any

  1. Retreive the YAML version of the configuration diff

nv config diff

- set:
   system:
     snmp-server:
       listening-address:
         all:
           vrf: mgmt
         all-v6:
           vrf: mgmt
       readonly-community:
         $nvsec$bc2dea2ea717f9e9aef0265a8f09f949:
           access:
             any: {}
       state: enabled

  1. Create a file under /opt/netris/etc/nvue/ with the YAML content you retrieved in step 2. For example, create the file /opt/netris/etc/nvue/50-snmp.yaml with the content above.


  1. Check if the configuration on the file is correct:

nv config patch /opt/netris/etc/nvue/<file>
nv config diff

  1. Check for any configuration errors by applying manually

nv config apply
