Version 89273-02 for AT-8900 and AT-9900 series switches 3
Software Maintenance Release note for Software Release 2.7.3
C613-10443-00 REV A
When either the Firewall was enabled or multiple L2TP tunnels were
configured, and a default route existed over an L2TP tunnel, it was possible
for an infinite internal packet loop to be created when a packet was sent
over the L2TP tunnel after the underlying interface route to the remote IP
had gone down. This caused a reboot to occur.
This issue has been resolved. (No PCR number.)
Level 2
Previously, the forwarding database was flushed instead of being aged out
when an STP topology change notification was received.
This issue has been resolved. (PCR number: 40185)
Previously, when a port or ports was moved from one VLAN to another, the
switch would reset both STP/RSTP instances that control the VLANs. This
behaviour is now changed to only reset the STP process on the STP instance
that the port(s) is joining. The switch will now also retain the port(s) edge-
port setting during the moving process.
This issue has been resolved.
A switch, lock-up could occur after enabling the use of QoS Counters via the
command SET SWITCH ENHANCEDMODE=QOSCOUNTERS.
This issue has been resolved.
When IP NAT was configured, a restart could occur if a TCP RST packet was
received with flags in addition to ACK.
This issue has been resolved.( PCR number: 40728)
The "SET IPV6 MLD ?" command was not displaying the correct parameters
on the command-line.
This issue has been resolved.
PPP TCP mss clamping was always fixing the mss to 1372. This issue is now
fixed, so that if the MTU or MRU is less than 1472, then mss clamping
clamps the mss to the correct size.
This issue has been resolved.
PPPoE has been modified so that a single host can be attached to multiple
access concentrators without a conflict of session ID's.
