Patch Release Note

PCR: 31233

Module: L3F

Level: 2

A filter entry was lost when the SET SWITCH L3FILTER ENTRY command did not succeed. This issue has been resolved.

PCR: 31236

Module: IPV6

Level: 3

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.

PCR: 31239

Module: IPV6

Level: 3

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.

PCR: 31247

Module: VLAN, IPG

Level: 2

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.

PCR: 31253

Module: SWI, SW56

Level: 2

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.

PCR: 31258 Module: IPG, DHCP

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={ARPICMP}]

[other-parameters]

SET DHPC RANGE [PROBE={ARPICMP}] [other-parameters]

PCR: 31259 Module: DHCP

Level: 2

When the DHCP server rejected a DHCPRequest message, the requested IP address was not logged correctly. This issue has been resolved.

PCR: 31268

Module: IPG

Level: 2

PCR 31128 introduced an issue that occasionally caused a fatal error with IP flows. This issue has been resolved.
