4 Patch Release Note
Software Maintenance Release note for Software Release 2.7.3
C613-10443-00 REV A
A change was made in the 2.6.1 software release to reset the PPP idle timer
for received traffic as well as transmitted traffic to avoid a PPP link idling
out when receiving unidirectional traffic. However, this has undesirable
side effects as it is not possible to control the received traffic. This change
has been removed. Users can avoid a PPP link idling out for received
unidirectional traffic by setting the value of the IDLE parameter to OFF, or
in the case of received multicast traffic, setting the IDLE parameter to a
value greater than the multicast hello timer.
When PPP was configured over L2TP over PPPoE, and the firewall was
enabled, a restart could occur in some circumstances.
This issue has been resolved.
If RIP was configured to explicitly exchange packets with a neighbour in
another subnet, the RIP packets from that neighbour were dropped.
This issue has been resolved.
When routers and switches were using CIDR addressing, with a unicast
address coinciding with a network broadcast address of class A, B, or C,
then they could incorrectly forward traffic as directed broadcasts, even
though the traffic was unicast (only).
This issue has been resolved. (PCR number: 50069)
When the router was acting as an L2TP Access Concentrator (LAC) it would
fail to negotiate a Virtual tunnel to another vendor’s LNS. This was due to
invalid Proxy LCP AVPs being used within the ICCN message.
This issue has been resolved. (No PCR number.)
In some 8924/9924 network configurations deploying QoS and IPMC
traffic, the QoS may have periodically miss-classified the traffic.
This issue has been resolved.
When the firewall was configured and the firewall ident proxy feature was
disabled, or if the firewall was disabled, TCP port 113 was still left open.
This issue has been resolved.
QoS was incorrectly misclassifying packets for small periods of time.
This issue has been resolved
