CR00014778 VLAN, Bridging 4 It was possible to specify a value of 0 for the ageingtimer parameter in the
command add and set vlan=vlan bridge, even though this value was
meaningless.
This issue has been resolved. The lowest valid value for ageingtimer is 1.

CR00015080 ATM 4 When an SHDSL or ADSL interface re-trained after having been in a “link up”
state, spurious error messages could appear on the console.
This issue has been resolved. The messages were not genuine error messages and
no longer appear.

CR00015130 Switch 4 The following commands have been deprecated in software versions 2.9.1 and
later, and therefore (correctly) have no effect on the switch:
set switch port=number thrashlimit=value
set switch port=number thrashrefill=value
Previously, if a user entered these commands, the switch incorrectly displayed an
“Operation successful” message.
This issue has been resolved. The switch now displays a warning message
indicating that the commands are deprecated.
For information about the commands that replace these commands, see the
“Limiting Rapid MAC Movement” section of the Switching chapter of the
Software Reference.
