Configuring SNMP Settings
On the SNMP Settings screen of the Initial Setup Wizard, you can configure Simple Network Management
Protocol (SNMP) for network management and monitoring.
1. If not already done, from the Credentials screen, click Next.
The SNMP Settings screen appears.
2. In the SNMP Mode field, select Enabled to configure SNMP.
3. In the SNMP Community String field, enter the string that grants access to the statistics of the
switch.
4. Click Next. The next wizard screen depends on the device mode:
• For Programmable Multiplex mode and FN MXL devices, proceed to the Summary screen.
• For all other device modes, proceed to the Uplink Failure Detection screen.
Configuring Uplink Failure Detection
On the Uplink Failure Detection screen of the Initial Setup Wizard, you can configure Uplink Failure
Detection (UFD). UFD provides detection of the loss of upstream connectivity. If there is a link failure, the
I/O Aggregator device disables downlink interfaces.
NOTE: This screen does not apply for devices in Programmable Multiplex mode or FN MXL devices.
1. If not already done, from the SNMP Settings screen, click Next.
The Uplink Failure Detection (UFD) screen appears.
2. To configure uplink failure detection, select Enabled or select Disabled to disable it.
3. If you select Enabled, configure a timer setting that prevents unwanted flapping of downstream ports
when the uplink port channel goes down and comes up. The configured value in seconds is how
long the device waits for the upstream port channel (LAG 128) to come back up before it disables the
server ports. Select one of the following:
• Default Defer Timer (10 sec)
NOTE: If you select this setting, if the uplink goes down, the device disables the downlink
within 10 seconds.
• Custom Defer Timer (enter a setting in seconds from 0 to 100)
4. Click Next and proceed to the Network Time Protocol screen.
Configuring Network Time Protocol
On the Network Time Protocol screen of the Initial Setup Wizard, you can configure an NTP time-serving
host to synchronize with the switch. With NTP, the switch can act only as a client to an NTP clock host.
NOTE: This screen does not apply for devices in Programmable Multiplex mode or FN MXL devices.
1. If not already done, from the Uplink Failure Detection screen, click Next.
The NTP screen appears.
2. From the Time Zone drop-down menu, select the time zone
3. Select Enable NTP Server.
4. In the Preferred NTP Server IP Address or URL field, enter the host name or IP address of the primary
NTP server.
5. In the Secondary NTP Server IP Address or URL (optional) field, enter the host name or IP address of
a secondary or backup NTP server.
