Patch Release Note

To disable enhanced fragmentation for IP NAT, use the command

DISABLE IP NAT FRAGMENT={ICMPUDPOTHER}

To configure the number of fragments permitted per packet for Firewall, use the command:

SET FIREWALL FRAGMENT=8...50

To configure the number of fragments permitted per packet for IP NAT, use the command:

SET IP NAT FRAGMENT=8...50

TCP has been excluded from this enhancement because TCP has the MSS (Maximum Segment Size) parameter for segment size control. Also, for PPPoE interfaces with a reduced MTU of 1492, a previous enhancement in PCR 02097 ensures that TCP MSS values in sessions carried by a PPPoE interface are clamped to a value that prevents fragmentation.

PCR 02116

Module: IPG PING

Network affecting: No

When pinging to a remote IP address with two or more different cost routes, if the preferred route became unavailable, the ping failed to switch to the less preferred route until the ping was stopped and restarted. This issue has been resolved.

PCR: 02371

Module: FIREWALL

Network affecting: No

When the system time was set to a time that was before or significantly after the current time, Firewall sessions were prematurely deleted. This issue has been resolved.

PCR: 03011

Module: OSPF

Network affecting: No

When the router priority was changed on a dynamic OSPF interface, the new priority did not appear in the output of the SHOW OSPF NEIGHBOUR command on neighbouring routers. The new priority only showed after the RESET OSPF command was executed on the neighbouring routers. This issue has been resolved.

PCR: 03026

Module: IPG

Network affecting: No

After setting the IGMP query timer with the SET IP IGMP command, and saving the configuration, the IGMP Other Querier timeout was not set to the correct value after a restart. This issue has been resolved.

PCR: 03027 Module: DHCP

Network affecting: No

Entries in the process of being reclaimed as static entries (and waiting for the remote IP to become routable), were disrupting the reclaim process. This prevented further entries from being reclaimed. DHCP static entries are now fully subject to normal reclaim processing.

PCR: 03032

Module: SWI

Network affecting: No

If the ENABLE IP IGMP command was executed before the ENABLE SWITCH L3FILTER command, Layer 3 filtering did not discard packets destined for the CPU. This issue has been resolved.

PCR: 03035 Module: OSPF

Network affecting: No

Link state advertisements could incorrectly show an area as a stub area. This happened during the time when a Direct Route (DR) was removed from a configuration and before a Direct Backup Route (BDR), or an Other Direct Route (Other DR) was elected. This issue has been resolved.
