4 Patch Release Note
Patch 86253-07 for Software Release 2.5.3
C613-10382-00 REV E
A filter entry was lost when the SET SWITCH L3FILTER ENTRY command
did not succeed. This issue has been resolved.
Link-local addresses can only be unicast addresses. If a link-local address
was added as an anycast address, no error message was returned. This issue
has been resolved. Now, an error message is returned stating that a link-
local address must be a unicast address.
The Maximum Transmission Unit (MTU) was not always set to the MTU
value in the ICMP Packet Too Big Message sent from the device. This issue
has been resolved.
After IGMP snooping was disabled, multicast data was not flooded to
VLANs. This was because the multicast route forwarding port map was
cleared. This issue has been resolved.
The forwarding database table sometimes did not update correctly when
multiple packets with the same MAC source address were sent to the switch
via different ports. This issue has been resolved.
If DHCP clients do not respond to echo requests, the DHCP server can not
detect an addressing conflict, so may offer inuse addresses to clients. This
issue has been resolved.
This PCR introduces a new parameter, PROBE, to the CREATE DHCP
RANGE and SET DHCP RANGE commands. This parameter allows for
address probing using ARP requests and replies instead of the normal ping
mechanism. This feature is limited to clients on the same subnet (broadcast
domain) as the DHCP server, and therefore can not be used with the
GATEWAY parameter.
The new syntax is:
CREATE DHCP RANGE=name [PROBE={ARP|ICMP}]
[other-parameters]
SET DHPC RANGE [PROBE={ARP|ICMP}] [other-parameters]
When the DHCP server rejected a DHCPRequest message, the requested IP
address was not logged correctly. This issue has been resolved.
PCR 31128 introduced an issue that occasionally caused a fatal error with IP
flows. This issue has been resolved.
