Level 1
A heavy processor load could lead to queuing RSTP BPDUs, which in turn
could lead to even more processor load, resulting in more queued BPDUs.
This issue has been resolved by improving the efficiency in the interaction
between RSTP TCN BPDUs and the hardware tables.
This issue has been resolved. (PCR number: 40672)
When failover occurred between a redundant pair of Load Balancing
devices, host ARP caches were not updated with the new Master's MAC
address, thus causing the hosts to lose connectivity until their ARP caches
timed out the stale entry. This issue has been resolved. (No PCR number.)
A reboot could occur while ageing out Firewall sessions when the device
was under heavy load and had many active Firewall sessions.
This issue has been resolved. (No PCR number.)
Level 1 This issue will cause significant interruption to network services, and
there is no work-around.
Level 2 This issue will cause interruption to network service, however there
is a work-around.
