Selecting SNMP in the left panel of the Options tab provides the following view, which enables you to configure SNMP options.
Changing a value from the system default causes a Default Value button to appear. Selecting this button changes the field back to the system default value.
These options apply to all users. For these settings to take effect, the ExtremeCloud IQ Site Engine Server must be restarted.
Configuration
- Length of SNMP Timeout
- The amount of time ExtremeCloud IQ Site Engine waits before trying to
contact a device again. The default value for this setting is 5 seconds. The value for this setting must be between 1 and 60 seconds.
Override this value on a per-device basis in the SNMP Timeout field in the Configure Device window.NOTE: When SNMP requests are redirected through the server, all SNMP timeouts are extended by a factor of four (timeout X 4) to provide time for the delays incurred by redirecting requests through the server.
- Number of SNMP Retries
- The number of attempts made to contact a device after an attempt at contact fails. The default setting is 0 retries, which means that ExtremeCloud IQ Site Engine does not retry contacting a device after the initial attempt is made. The value for this setting must be between 0 and 10 retries.
Override this value on a per-device basis in the SNMP Retries field in the Configure Device window.
- Use NetSNMP IPv6
- The Use NetSNMP IPv6 option enables you to use SNMP to manage network devices to which IPv6 addresses are assigned. You must have this option selected in order to be able to add a device with an IPv6 address.
MIB Directories on Server
- Use MyMibs Directory on the Server
- Select this checkbox to enable the ExtremeCloud IQ Site Engine Server to also use the
MyMibs directory (e.g. the MIBs are included in the SNMP server stack). This MIB information is then distributed to the ExtremeCloud IQ Site Engine
remote clients.
- Use Third-Party Directory on the Server
- Select this checkbox to enable the ExtremeCloud IQ Site Engine Server to also use the
third-party directory, where proprietary, client-based FlexViews and MIB Tools (Enterprise MIBs owned by other companies) are stored, not standard IETF or IEEE MIBs. This MIB information is then distributed to the ExtremeCloud IQ Site Engine
remote clients.
| CAUTION: | Do not use the MyMibs or third-party directories unless it is required on your network, as selecting these options can cause ExtremeCloud IQ Site Engine Server instability and undesirable consequences. |

Manage SNMP Configuration
- Enable
- Select this checkbox to enable SNMP access to the ExtremeCloud IQ Site Engine server for the profiles you select in the SNMP Profile(s) drop-down list. Deselecting this checkbox only enables SNMP access to the ExtremeCloud IQ Site Engine server for the credentials you configured when you installed ExtremeCloud IQ Site Engine.
- SNMP Profile(s)
- Select the profiles with SNMP access to the ExtremeCloud IQ Site Engine server. The type of SNMP access (e.g. read-only or read-write) is configured for the profile by assigning a set of SNMP credentials to the profile on the Administration > Profiles tab.
You can also configure these options directly by editing the /etc/snmp/snmpd.conf file.
| NOTE: | There are certain cases when these options are not available. In the event that these options are unable to be edited, configure the options directly via the snmpd.conf file. |
