79.15 Firmware Upgrade
You can upgrade the Switch’s firmware through Web Configurator or NCC.
Firmware Upgrade Through NCC
In cloud management mode, NCC will first check if the firmware on the Switch needs to be upgraded. If
it does, the Switch will upgrade the firmware immediately. If the firmware does not need to be
upgraded, but there is newer firmware available for the Switch, then it will be upgraded according to
the firmware upgrade schedule for the Switch on the NCC.
On the NCC web portal, go to Site-wide > Configure > Firmware management to schedule the firmware
upgrade time.
Note: While the Switch is rebooting, do NOT turn off the power.
IP Address/Host
Name
Enter the IP address or host name of a device to which you want to perform a traceroute.
Click Trace Route to have the Switch perform the traceroute function. This determines the
path a packet takes to the specified device.
TTL Enter the Time To Live (TTL) value for the ICMP Echo Request packets. This is to set the
maximum number of the hops (routers) a packet can travel through. Each router along the
path will decrement the TTL value by one and forward the packets. When the TTL value
becomes zero and the destination is not found, the router drops the packets and informs the
sender.
Wait Time Specify how many seconds the Switch waits for a response to a probe before running
another traceroute.
Queries Specify how many times the Switch performs the traceroute function.
