Patch 86222-21 For Rapier Switches and AR800 Series Modular Switching Routers

5

Lost OFFER messages on the server are now handled correctly.

The DHCP server now correctly handles DHCP clients being moved to a different interface on the DHCP server after they’ve been allocated an IP address.

PCR: 02203

Module: IPG

Network affecting: No

Responses to DNS requests received by a DNS relay agent, and forwarded to the DNS server, were returned to the requester with a source IP address of the DNS server rather than the DNS relay agent. This issue has been resolved.

PCR: 02208

Module: LOG

Network affecting: No

Log messages are no longer stored in NVS.

PCR: 02214

Module: IPG

Network affecting: No

A buffer leak occurred when a large number of flows (over 4000) were in use and needed to be recycled. This issue has been resolved.

PCR: 02215

Module: FILE

Network affecting: No

When the only feature licence in the feature licence file was disabled, the licence file stored on FLASH memory did not change. This was due to a previous enhancement in PCR 02184 which prevented existing files being deleted before a new version was stored. This issue has been resolved.

PCR: 02220

Module: SWI

Network affecting: No

The EPORT parameter in the ADD SWITCH L3FILTER ENTRY and SET SWITCH L3FILTER ENTRY commands was matching multicast and broadcast packets with software filtering. This issue has been resolved.

PCR: 02224

Module: SWI

Network affecting: No

Some switch chip register values have been changed to improve QoS support on Rapier G6 and Rapier G6f switches.

PCR: 02229

Module: IPG

Network affecting: No

The PURGE IP command now resets the IP route cache counters to zero.

PCR: 02242

Module: IPG

Network affecting: No

On a Rapier 24, adding an IP interface over a FR interface caused an

ASSERT debug fatal error. This issue has been resolved.

PCR: 02246

Module: VRRP

Network affecting: No

The ARL entry for the virtual router MAC was incorrectly showing a numerical value. The entry now shows the CPU’s port value.

PCR: 02250

Module: FIREWALL

Network affecting: No

Sometimes the Firewall erroneously used NAT. This issue has been resolved.

PCR: 02259

Module: DHCP, IPG

Network affecting: No

A dual Ethernet router was incorrectly accepting an IP address from a DHCP server when the offered address was on the same network as the other Ethernet interface. An error is now recorded when DHCP offers an address that is in the same subnet as another interface.
