Firewall

When only NAT was enabled on the firewall, during some TCP connections in

which either end of the connection sends FIN (finished) messages immediately

after sending some data and the other end ACKs (acknowledges) the data and

the FIN message consecutively, the firewall sometimes incorrectly interpreted the

first ACK message (intended for the data) as belonging to the FIN message and

prematurely shut the connection down. This could prevent the firewall from

opening up new connections using the same port numbers.

This issue has been resolved.

BGP,

When BGP learned new best routes for a particular destination, it did not always

clear any active IP flows that used the previous best route. Therefore, the router

or switch continued to forward traffic sub-optimally.

This issue has been resolved. Now, when BGP inserts new routes into the IP route

table, it deletes all active route flows, so any active flows change to using the new

route. The time taken to delete a full table of IP flows has also been greatly

reduced.

Switch

Sometimes IP routed traffic would be sent out the correct port, but with the

destination MAC of another device on the network. This issue was most likely to

occur in configurations that use multi-homed interfaces on multiple VLANs for

end devices.

This issue has been resolved.

Switch

2

When the command enable ip macdisparity was used, and a static ARP entry

was configured with an L2 multicast MAC address, the switch should have

broadcast traffic to that multicast MAC address out all ports in the VLAN. This

was not happening.

This issue has been resolved.

VRRP

After manually disabling the master VRRP router, sometimes a backup router that

should assume master status would not do so, and VRRP would cease to function

properly.
