We have identified a security bug within the core firmware installed and running on the following access switches within our network:
primary-sw.r02
backup-sw.r02
primary-sw.r03
backup-sw.r03
primary-sw.r04
backup-sw.r04
Due to the nature of this security bug we have had little option but to immediately update these devices. This update required the above switches to be reloaded so the new IOS could be loaded. Services with a redundant network links to other parts of our network would have seen no disruption.
Other switches are unaffected and this work is now complete.
We apologise for any inconvenience caused.
