22 Patch Release Note
Patch 86251-08 for Software Release 2.5.1
C613-10356-00 REV I
If the firewall received a packet with an incorrect TCP checksum and ACK
number, the packet was sent to the client. Such packets are now rejected by
the firewall. This patch fixes the problem.
Packet throughput was reduced if an incoming packet did not match the
first entry of the IP filter table. This issue has been resolved.
When IP filters were deleted, the corresponding IP flow cache was not
invalidated. This issue has been resolved.
A fatal error occurred when a device received a PKI certificate that exceeded
the CERTSTORELIMIT parameter in the SET PKI command. This
parameter sets the maximum number of certificates that can be stored on
the device. This issue has been resolved.
A fatal error occurred if the number of DVMRP interfaces being added
exceeded the limit. This issue has been resolved.
Occasionally a fatal exception may have occurred when sending BGP
aggregate routes. This issue has been resolved.
IGMP snooping entries were not being deleted from the hardware table.
This issue has been resolved. Also, port timers are now updated when the
IGMP timeout is changed.
The output of the SHOW DVMRP FORWARDING command did not
display the forwarding ports. This issue has been resolved.
When adding a port to a VLAN, any STP ports that had been disabled in the
default STP were re-enabled. This issue has been resolved.
When the DELETE DHCP RANGE command was executed, DHCP
attempted to reclaim the addresses in that range. It also tried to reclaim
addresses in that range that were not allocated at that time, resulting in
duplicate addresses appearing on the free list for allocation. This has been
resolved by allowing DHCP to reclaim only those addresses that are
currently in use by one of its clients.
The list of multicast groups for each Rendezvous Point occasionally became
corrupted, and this could cause a fatal error. This issue has been resolved.
