All of the upgrades below are scheduled to occur, July 26, 6:00 a.m. - 12:00 p.m.
Campus Switch Firmware Upgrades [CHG0035940]
The Access Layer Team will be performing firmware upgrades on Cisco Catalyst 9200, 9200L, 9300, and 9300L switches. The switches are expected to be down for 15 minutes while they reboot, during which all devices connected to the switch will be down. There is a possibility that if there is an unexpected error, a few switches could be down for longer (1-4 hours) if the switch does not boot back up properly. Attached is a list of switches, along with their locations, that will be affected. These buildings could be fully Cat9k or partially Cat9k. If you have questions about what will go down in a specific building in this list, please either check the attached Excel file for the exact switches (there are multiple sheets in the file) or reach out to me via Email or Teams. We have excluded switches in GTPD, GT Savannah, dedicated DGMS switches, and SCADA switches at this time. They will be coordinated individually at a later date given their high sensitivity.
Moving Wireless Controller Cabling to new Hardware [CHG0035810]
The wireless controllers which support all wireless networking for the Atlanta and Savannah campuses will be re-cabled and connected to new network switches during the maintenance window. This will cause a brief 5 minute disruption in wireless network connectivity (this includes the eduroam, GTother, and GTvisitor SSIDs) when the cabling is moved to the new hardware. Most wireless client devices will automatically reconnect, but some devices may need to be disconnected from and reconnected to eduroam if connectivity is not automatically re-established.
eduroam Client Network Changes [CHG0035809]
A portion of the IP address space used in the eduroam client networks will be re-configured to support a larger number of connected devices ahead of the upcoming Fall semester. Most users/devices will not experience any disruption as a result of this work, though some devices may need to be disconnected from and reconnected to eduroam if connectivity is not automatically re-established.
Rebooting campus-border-pa firewall to restore logging services [CHG0035902]
The OIT Network Engineering firewall team will be conducting a failover procedure from the primary border firewall to the secondary unit, and subsequently rebooting the primary unit once failover is complete to restore logging services. This change is non-impactful and will not result in user connectivity disruption at any point. Once the primary firewall has fully rebooted and all functionality is restored, technicians will fail the firewall back to the primary unit in order to revert to normal operations. This failback will also happen without disruption to user connectivity or services.
