32 Patch Release Note
Patch 86231-10 for Software Release 2.3.1
C613-10328-00 REV J
When a Rapier CPU was handling a large amount of traffic and a busy
egress port went down, it was possible for the transmission of packets by
the CPU to cease. This issue has been resolved.
Support for the AT-40/41 100Mbit fibre uplink modules has been added.
On Rapier “i” series models, outgoing packets (originating from the CPU)
consisting of chained buffers were corrupted by the insertion of four bytes
at the end of the first buffer in the chain. This affected L2TP calls over an
Ethernet connection. This issue has been resolved.
On the Rapier 48 in certain circumstances (e.g. a routing update or ARP
deletion) the layer 3 switching table became corrupted and the wrong
egress port was used for flows. This issue has been resolved.
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.
A fatal error occurred when forwarding IP packets with VRRP enabled. This
issue has been resolved.
When trunking was in operation, in some instances the switch transmitted
tagged packets on untagged trunk ports. This issue has been resolved.
When the speed of one or more switch ports was forced to a half duplex
setting and the ports were then added to a trunk group configured for full
duplex operation, the port settings were not overridden by the trunk group
speed setting. The trunk group speed setting will now take precedence over
the port speed setting.
PAC cards with the Hifn 7951 chipset now operate correctly on Rapier
switches. PAC cards with the older Hifn 7751 chipset are not supported on
Rapier switches.
The checksum in VRRP advertisements was not being calculated correctly.
The calculation was not compatible with the RFC. This issue has been
resolved.
