Adding SNMP switches
Prerequisites
Create an SNMP Profile with the proper SNMP configuration as used on this device. If applicable, create a Credential Profile with the proper SSH username / password that will be used to run commands on this device. As needed, create Commands and Command Groups to assign to this device.
SNMP Device Configuration
All SNMP devices are managed via SNMP using the Python EasySNMP and pysnmp library. You will need to create the proper SNMP Read/Write configuration to allow OpenL2M to work on supported devices. ::doc::Please see the section with SNMP examples for more details.<snmp_configs>
Please refer to your device snmp documentation for more details.
OpenL2M Configuration
From the top-right Admin menu, go to Administration, and then click on Switches, or click the “+ Add” option
Configure the name to show in the menu (does not need to be the switch hostname), and add a description if so desired.
Add the IP v4 address or resolvable DNS name used to connect to the device.
Note
HPE Comware switches are fully Read-Write supported via SNMP, as are older Cisco switches. Most Aruba AOS-CX devices have minimal write capability via SNMP (use REST API for control). Juniper switches are Read-Only via SNMP.
In the Connection Configuration section, set:
Connector Type: to
SNMP: for fully snmp manageable devices (Cisco, HP/Procurce, HPE).
SNMP Profile:
Select the proper SNMP profile is this is an SNMP managed switch.
Credentials Profile:
Select the proper profile, required for Commands, API, PyEZ, NetConf, etc. If you want to allow ‘show/display’ commands, you need to add a profile here!
Group Membership section:
For this device to be visible to users (including Admin) in their menu, you need to add it to at least one Group!
Optional settings
In the Commands Configuration section, set:
Command List:
Select the command list desired, if any. See here for more <commands>
In View Options section, set:
Indentation Level:
If > 0, will add some spaces in the menu before the switch name; this can look nicer !
Default View:
The Default View setting defines the opening tab when a user clicks on the switch. Setting this to Details is useful for routers, so that ARP and LLDP information are loaded immediately. Note that it then take a little longer to render the page, due to the extra data that needs to be read from the device.
In the Access Options section, set:
Status:
Note: switches will only show in the list if their status is Active. For SNMP devices, devices need to have an SNMP Profile applied! Likewise, if a switch does not have a Credentials profile, interface commands and global commands options will not show.
Read-Only:
If a switch is marked Read-Only, no user (not even admin), can change settings on the switch. However, if commands are configured, they can be executed. This is useful for e.g. routers.
Bulk-Edit:
The Bulk Edit setting is enabled by default. If disabled (un-checked), this switch will not allow multiple interfaces to be edited at once.
Poe-Toggle:
If selected, users can toggle PoE on all ports, including those ports on vlans they do not have access to. (e.g this is useful for Wifi Access Points, VOIP Phones, etc.)
Edit description:
Enabled by default. If not selected, users cannot edit the interface descriptions on this device (regardless of rights!)
Group Membership section:
Finally, at the end you can add this new device to one or more groups.
