Data Center Firewall maintenance July 11, 5-7 am
During the 5-7 am maintenance window on Tuesday, July 11, ENCS and DCS will be performing maintenance on the Data Center Firewalls in Tower Rd and Computer buildings. This maintenance is being performed to re-enable jumbo frame capabilities which had been erroneously turned off during troubleshooting in a previous network event.
Panorama will be available throughout the maintenance, but please do not make any changes to rule sets during the July 11 maintenance window as those changes may not properly synchronize and cause complications.
Although every precaution will be taken to minimize impact to traffic flows during the maintenance, each firewall will need to be individually taken out of service, need configuration changed, need to be rebooted and need to be brought back in to service. As the firewalls are taken out of and in to service, there may be up to four individual disruptions of up to 35 seconds as the network re-converges. These outages will be spread across the maintenance window. Please monitor your applications and services to ensure that functionality is maintained or if corrective action is needed.
