Description
With this release, you can configure deny mac
addresses on a global level or on a per port level.
Fragmented IP packets with undersized fragments
and overlapping fragments are dropped.
Packets with IP options in their header are
automatically dropped. Enabling the ip
ip-option-process command allows the device to
process packets that use IP options.
You can use IPv4 ACLs to filter the packets intended
for the management processor to protect the
management module from being overloaded with
heavy traffic that was sent to one of the Layer 3
Switch IP interfaces.
Static routes can be configured with tag values.
In this release, you can configure IPv4 MTU to be
greater than 1500 bytes.
The following have been implemented to enhance the
password features in the device:
•
New rules for enable and user passwords
•
Users are now required to accept the message
of the day
•
Users are locked out if they reach the maximum
number of login attempts and have not logged in
successfully.
•
Previous passwords used are now stored in the
CLI. When users change their password, they
must select a password that has not been
stored in the CLI.
•
A password can now be set to expire
