Security Type
Description
EAPOL-based security
(IEEE 802.1X)
Enable the exchange of authentication information between any end

such as a RADIUS server.
IP manager list
Limit access to management features of the switch based on the
management station IP address.
SNMPv3
Enable access to the various services by using password authentication
(MD5), secure-hash algorithm, and encryption using the Data
Encryption Standard.
SSL
Provide a secure Web management interface.
SSH
Replace telnet and provide a secure access to the CLI.
For more information about specific security features, see Configuring
and Managing Security for Nortel Ethernet Routing Switch 4500 Series,
Software Release 5.0 (NN47205-505).
Port mirroring
with port mirroring, also referred to as conversation steering, you can
designate a single switch port as a traffic monitor for a specified port.
You can specify port-based monitoring for ingress and egress at a specific
port. You also can attach a probe device, such as a Nortel StackProbe*, or
equivalent, to the designated monitor port.
Note: Use the CLI or the Web-based Management Interface to
configure port mirroring.
Auto-MDI/X
The term auto-MDI/X refers to automatic detection of transmit and receive
twisted pairs.
When auto-MDI/X is active, any straight or crossover category 5 cable can
provide connection to a port. If autonegotiation is disabled, then auto-MDI/X
is not active.
Auto-polarity
Auto-polarity refers to the ability of the port to compensate for positive and
negative signals being reversed on the receive cables.
The Nortel Ethernet Routing Switch 4500 Series support auto-polarity. With
autonegotiation enabled, auto-polarity automatically reverses the polarity
of a pair of pins from positive to negative or negative to positive. This
