SUMMARY: IXP switch software upgrade to support 10GE interfaces. Switch will
be rebooted and all services are down for max 60 minutes.
FICIX2-GE will be in full operation during the maintenance and members are
encouraged to move traffic as much as possible to FICIX2-GE before maintenance
starts.
Members should notify internal and external operational units about this
planned work, most important being NOC's and Helpdesks/Customer Services.

DETAILS: Current IXP switch is running software which doesn't support 10GE
interfaces. An upgrade is required to supply 10GE ports to members.
There are pending orders for 10GE connectivity.

Software upgrade require hardware reboot's. Tests indicate that the process
takes at minimum 20 minutes, and all services should revive withing 30 minute
timeframe. If problems arise and several reboot's are required, the maintenance
window may last full 60 minutes.
All ports are forced down during the maintenance to avoid flapping.

RISK ANALYSIS: Unpredicted and unexpected results may arise. Worst case scenario
for IXP switch is, that the upgrade is not succesfull and current software will
be restored. This would delay the 10GE service introduction.

FICIX2-GE will be in full operation during the maintenance. Please notice
that if routers connected to FICIX1-GE do not recognize port down situation
the time for rerouting may be significant (BGP default dead timer is 90 seconds).
To avoid significant routing black-holes connected members are encouraged
to move traffic as much as possible to FICIX2-GE before maintenance starts.

Members are also encouraged to make sure that networks connected FICIX2-GE are
capable to handle the required traffic flows during the maintenance, as well
as to make sure that backbones do survive the abnormal traffic patterns.

Members should notify internal and external operational units about this
planned work, most important being NOC's and Helpdesks/Customer Services.
