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.
