Patch Release Note
Patch 86241-05 for Software Release 2.4.1
C613-10340-00 REV E
Features in 86241-06
Patch 86241-06 includes all issues resolved and enhancements released in
previous patches for Software Release 2.4.1, and the following enhancements:
When more than two firewall policies were configured, an unexpected
switch restart sometimes occurred. This issue has been resolved.
Dynamic Port Security allows for dynamic MAC address learning on a
switch port. If a MAC address is unused for a period of time, it will be aged
from the database of currently accepted MAC addresses. This allows the
learning of new MAC addresses. Dynamic Port Security is useful because
port security allows the number of devices that are connected to a
particular switch port to be limited.
For more information on Dynamic Port Security, see “Dynamic Port
Security” on page 29 of this patch release note.
PIM join messages were being sent by a switch connected to an upstream
and a downstream switch or router in the same VLAN when a multicast
group had no members. This issue has been resolved.
The switch did not always advertise its preferred routes to destinations that
were affected by flapping routes. In these conditions, a BGP network does
not run efficiently. This issue has been resolved.
A switch port belonging to an enabled STP instance would not respond to
ARP requests if the port had been disabled from STP operation. This
prevented the flow of some types of traffic into affected switch ports. This
issue has been resolved.
When a connection is made by Telnet, or directly through the ASYN port, a
TTY session is created with:
■
an idle timeout time. The default idle time is zero, which means the TTY
session will not time out if there is a lack of activity. If a server is
configured on the switch, and the idle time attribute value pair (AVP) is
configured on the server and is received by the switch, the value
of the idle time from the server is used to set the TTY session.
■
a timeout of zero, which means that the TTY session will not time out. If a
server is configured on the switch, and the timeout attribute
value pair (AVP) is configured on the server and received by the
switch, the value of the timeout from the server is used to set
the TTY session timeout. After the timeout period has elapsed, the user
will either be disconnected by termination of their TTY connection (the
default setting), or have their privilege level reduced to USER (the lowest
privilege level). If the user’s privilege level is already at the lowest level,
then the user will be disconnected by termination of their TTY connection.
If the user’s privilege level is reduced, the TTY session timeout count is
reset to its initial value.
