-> copy [e-mail]:sfilename kernel.f2k
-> sync
where xxx.xxx.xxx.xxx is the TFTP server IP address, sfilename is the server filename
of the kernel, and KERNEL.F2K is the name of the file. If you do not specify the server
address, a permanent or more recent override TFTP server address will be used, if
you have previously defined one.
CAUTION:
After the kernel is copied, do not power down the router until you have either issued a
sync command or rebooted the router. Otherwise, the file is not written to flash
memory.
Step 4 After successfully copying the kernel to the router, reboot the router from flash
memory via the reboot command. If a problem occurs during the upgrading process,
try the command again (do not reboot until you have successfully copied the kernel).
If you have altered the boot procedure order in any way, be sure to reset the router
system to boot from flash memory first. Verify the software revision number by
issuing the vers command.
The router system is now ready to be re-configured if necessary. The configuration
files are unchanged by the upgrade process.

Quality of Service (QOS)
Mission-critical and real-time Internet applications demand a network that provides
high bandwidth and low latency. Such applications cannot tolerate unpredictable
degradations of network services. Therefore, network services must contain features
that provide adequate assurance of sustained service levels. Quality of Service
features actively manage network resources to sustain service levels for priority
applications. Some of the benefits associated with Quality of Service include:
• Guaranteed available bandwidth and minimum delays to real-time Voice over
IP traffic
• Dynamic allocations of bandwidth to non-critical applications
• User control over network traffic levels, and potential cost-efficiencies
• Advanced differentiation of network services
• Measurement and reporting of network service levels
This router provides Quality of Service using two methods: Differentiated Services
Framework (DiffServ) and Weighted Fair Queuing (WFQ).
