I upgraded to 7.2.1 and with it my SB3's firmware today. I got this message from the Office of IT:
Dear Simon, A device attached to the campus network is responding incorrectly to IP broadcast traffic. The traffic is from hardware address: 0:4:20:12:48:7d which is registered as the wireless address of the device. [viz., my SB3] When this device receives an IP broadcast packet from the campus and it decides that it is not interested in the packet (or that something is in fact wrong with the packet), the device responds by sending an ICMP error message. This is not correct behavior; no device should ever send an ICMP error message in response to broadcast or multicast traffic. That's because when many devices behave in this erroneous fashion, it creates very large traffic spikes on the network, degrading network service for everyone. On large networks, such as many that compose the campus network, this is a real danger.(In certain situations, such behavior can even result in self-sustaining broadcast storms that keep the network unusable.) This sort of behavior can be caused by a bug in the device's IP stack, requiring a bug fix from the vendor of the device. (In some unusual situations, it may also be possible for a device to exhibit this behavior as a result of incorrect configuration, but this is uncommon.) Because this erroneous traffic degrades network service, OIT has blocked it from using the campus wireless service. If you have any questions, please call the Help Desk or visit the Solutions Center. The Help Desk is open 24 hours a day, 7 days a week. The Solutions Center is open to walk-ins from 9am to 3pm, Monday through Friday. Regards, OIT Help Desk ~~~ It seems unlikely that these events (the upgrade and subsequent ICMP errors) are unrelated; so: there is likely a bug in the latest firmware. I thought I should post this here so as someone can investigate it further.
