Level
1 Previously, if trunk ports were configured and/or STP was enabled, the CPU
flooded GARP frames in an incorrect manner, which could cause network loops.
This issue has been resolved. GMRP frames are (correctly) flooded, and GVRP
frames are now only flooded if GARP is disabled.
1 If the switch had learned a very large number of routes from BGP and the
interface went down, IP ran out of memory when recalculating the best routes
to use. This was exacerbated when the high memory usage triggered the BGP
backoff mechanism which in turn disabled the BGP peers, which caused IP to
recalculate even more routes. The switch eventually rebooted due to memory
exhaustion.
This issue has been resolved by improvements to memory allocation and IP route
queuing, and by enforcing limits on the number of IP routes.
1 When PIM6 was configured on the switch, and it received an IPv6 multicast
stream for which it had no downstream interface to forward the stream to, a
reboot could occur.
This issue has been resolved.
