WebView Switches
Learning Mode
Defines the locked port type. The
Learning Mode
field is enabled only if
Locked
is selected
in the
Interface Status
field. The possible field values are:
Classic Lock
•
Locks the port using the classic lock
mechanism. The port is immediately locked, regardless
of the number of addresses that have already been
learned.
Limited Dynamic Lock
•
Locks the port by deleting
the current dynamic MAC addresses associated with
the port. The port learns up to the maximum addresses
allowed on the port. Both relearning and aging MAC
addresses are enabled.
In order to change the Learning Mode, the Lock Interface
must be set to
Unlocked
. Once the mode is changed, the
Lock Interface can be reinstated.
Max Entries
Specifies the number of MAC addresses that
can be learned on the port. The
Max Entries
field is enabled
only if
Locked
is selected in the
Interface Status
field. In
addition, the Limited Dynamic Lock mode is selected. The
default is
1
.
Action on Violation
Indicates the action to be applied to
packets arriving on a locked port. The possible field values
are:
Discard
•
Discards packets from any unlearned source.
This is the default value.
Forward Normal
•
Forwards packets from an unknown
source without learning the MAC address.
Discard Disable
•
Discards packets from any unlearned
source and shuts down the port. The port remains shut
down until reactivated, or until the device is reset.
Enable Trap
Enables traps when a packet is received on
a locked port.
Trap Frequency
The amount of time (in seconds)
between traps. The default value is
10
seconds.
Security > Multiple Hosts
The
Multiple Hosts
screen allows network managers to
configure advanced port-based authentication settings
for specific ports and VLANs.
Security > Multiple Hosts
Port
Displays the port number for which advanced port-
based authentication is enabled.
Enable Multiple Hosts
When checked, indicates that
multiple hosts are enabled. Multiple hosts must be
enabled in order to either disable the ingress-filter, or to
use port-lock security on the selected port.
Action on Violation
Defines the action to be applied to
packets arriving in single-host mode, from a host whose
MAC address is not the supplicant MAC address. The
possible field values are:
Discard
•
Discards the packets. This is the default
value.
Forward
•
Forwards the packet.
Discard Disable
•
Discards the packets and shuts
down the port. The ports remains shut down until
reactivated, or until the device is reset.
Enable Traps
When checked, indicates that traps are
enabled for Multiple Hosts.
Trap Frequency
Defines the time period by which traps
are sent to the host. The Trap Frequency (
1–1,000,000
)
field can be defined only if multiple hosts are disabled.
The default is
10
seconds.
The table contains the following additional fields:
Status
Indicates the host status. If there is an asterisk (*),
the port is either not linked or is down. The possible field
values are:
Number of Violations
Indicates the number of packets
that arrived on the interface in single-host mode, from
a host whose MAC address is not the supplicant MAC
address.
