Patch Release Note

Patch 86241-05 for Software Release 2.4.1

C613-10340-00 REV E

The virtual MAC address was used as the source MAC for all packets 
forwarded on an interface associated with a Virtual Router (VR). This was 
confusing when multiple VRs were defined over the same interface because 
only one virtual MAC address was ever used. The other virtual MAC 
addresses (for the other VR's) were only used if the source IP address 
matched the VR’s IP address. To avoid this confusion, the system MAC 
address is now always used unless the source IP address of the packet is the 
same as the VR’s IP address.

When route aggregation was enabled, the atomic aggregate was not being 
set. This issue has been resolved.

HTTP requests from a fixed IP address were erroneously reported as a host 
scan attack in the Firewall deny queue. This issue has been resolved.

The following issues have been resolved:

The RESET PIM INTERFACE=VLAN command was not working 
correctly.

Packets with Time to Live (TTL) set to less than 4 were not being 
forwarded.

VLAN tags were not being inserted into IP multicast packets on multi-
tagged ports. 

A fatal error occurred when PIM and RIP were both running.

ARL message interrupts have been re-enabled after a software table rebuild 
to fix synchronisation of the software forwarding database with the 
hardware table.

The CREATE CONFIG command did not save the SOURCEPORT 
parameter to the configuration file when the low value of the source port 
range was set to zero. This issue has been resolved.

Report sending and default routes were not working correctly. Also, the 
SHOW CONFIGURATION DYNAMIC and SHOW 
CONFIGURATION=DVMRP commands were not working correctly. These 
issues have been resolved.

TELNET sessions are now closed with “^D” only when the session is in the 
login state. 

DHCP now processes Discover messages smaller than 300 bytes.
