Patch Release Note

PCR: 02003

Module: FIREWALL

Network affecting: No

The timeout value for ICMP session entries in the firewall can now be adjusted via the OTHERTIMEOUT parameter of the SET FIRE POLICY command. Note: if the value for OTHERTIMEOUT is set to more than 10 minutes the timeout used for ICMP sessions will default to 10 minutes.

PCR: 02007 Module: DHCP

Network affecting: No

When a DHCP server received a DHCP DISCOVERY packet passed by a relay agent, requesting an IP address that did not belong to the subnet the client and the relay agent were attached to, it offered the requested address if it was available. The DHCP server will now only offer an IP address from the subnet that connects the client and the relay agent.

PCR: 02008

Module: TRIGGER

Network affecting: No

The first periodic after day trigger boundary (i.e. midnight) did not occur. A range check error occurred due to an incorrect comparison. These issues have been resolved.

PCR: 02011

Module: PING

Network affecting: No

Stopping a trace route using STOP TRACE occasionally caused a fatal error.

This issue has been resolved.

PCR: 02012

Module: IPG, VLAN, SWI

Network affecting: No

IGMP reflooded packets with VLAN tagging were not processed correctly.

This issue has been resolved.
