Message: On Monday, April 20 from 5:00 – 6:00 a.m. PT, the ITS Wireless team will be upgrading ResNet Wireless LAN Controllers RES-B-9800-80 and RES-M-9800-80 from IOS-XE 17.15.3 to 17.15.5, the current Cisco recommended release. This upgrade addresses recent software defects that caused controller instability. ResNet wireless clients (excluding Ridge Walk Living and Learning) may experience a brief disconnection during Access Point failover. Devices will reconnect automatically. Impact is expected to be minimal due to pre-staging steps completed prior to the maintenance window, including AP image pre-download to expedite rejoin times.
Please contact ITS Service Desk at (858)246-HELP(4357) or servicedesk@ucsd.edu if you have any questions or concerns.
