18Patch Release Note

PCR: 01242

Module: CORE, SNMP

Network affecting: No

The switch now delays sending link traps immediately after a restart to give the link to the trap host time to come up. A similar change has been made for the cold start trap. After a 10s delay, all interfaces which are UP have a link trap generated for them. After that, link traps are sent as normal.

PCR: 01244

Module: SWI, CORE, IPG

Network affecting: No

Processing invalid UDP packets caused a memory leak. This issue has been resolved. Additional debugging facilities were added.

PCR: 01246

Module: SWI

Network affecting: No

The default setting for the switch port parameter INFILTERING is now OFF, as specified in IEEE802.1Q. A VLAN will still reject these packets if they are not from valid VLAN member ports.

PCR: 01247

Module: IPG

Network affecting: No

The IGMP snooping forwarding process now correctly selects outgoing ports when DVMRP is managing the multicast routing information.

PCR: 01248

Module: SWI

Network affecting: No

A configuration problem prevented trunking of gigabit ports at 100Mbit speeds. This issue has been resolved. The A39 gigabit copper uplink reverted to autonegotiation after a restart, even if it was configured to a fixed speed. This issue has been resolved. When the port has been configured for a fixed speed, the mode is now set to MDIX, not MDI.

PCR: 01254

Module: PRI

Network affecting: No

When an M2 version of the AR020 PRI E1/T1 PIC was installed in a AR040 NSM it was not possible to select the T1 mode of operation regardless of the jumper setting. This issue has been resolved.

PCR: 01256

Module: Firewall

Network affecting: No

A fatal error occurred when the firewall discarded disallowed multicast packets. This issue has been resolved.
