Documentation Updates

Update to the “Configuring IEEE 802.1x Port-Based Authentication” Chapter

This guideline was added to the “802.1x Authentication” section of the “Configuring IEEE 802.1x

Port-Based Authentication” chapter.

• When IP phones are connected to an 802.1x-enabled switch port that is in single host mode, the

switch grants the phones network access without authenticating them. We recommend that you use

multidomain authentication (MDA) on the port to authenticate both a data device and a voice device,

such as an IP phone.

Update to the “Configuring Embedded Event Manager” Chapter

Embedded Event Manager 3.2

Embedded Event Manager (EEM) is a distributed and customized approach to event detection and

recovery offered directly in a Cisco IOS device. EEM offers the ability to monitor events and take

informational, corrective, or any desired EEM action when the monitored events occur or when a

threshold is reached. An EEM policy is an entity that defines an event and the actions to be taken when

that event occurs.

EEM 3.2 is supported in Cisco IOS Release 12.2(52)SE and later releases, and introduced many new

features.

EEM 3.2 introduces the following new event detectors:

• Neighbor Discovery—Neighbor Discovery event detector provides the ability to publish a policy to

respond to automatic neighbor detection when:

–

a Cisco Discovery Protocol (CDP) cache entry is added, deleted, or updated.

–

a Link Layer Discovery Protocol (LLDP) cache entry is added, deleted, or updated.

–

an interface link status changes.

–

an interface line status changes.

• Identity—Identity event detector generates an event when AAA authorization and authentication is

successful, when failure occurs, or after normal user traffic on the port is allowed to flow.

• Mac-Address-Table—Mac-Address-Table event detector generates an event when a MAC address is

learned in the MAC address table.

Note The Mac-Address-Table event detector is supported only on switch platforms and can be used

only on Layer 2 interfaces where MAC addresses are learned. Layer 3 interfaces do not learn

addresses and routers do not usually support the mac-address-table infrastructure needed to

notify EEM of a learned MAC address.

EEM 3.2 also introduces new CLI commands to support the applets to work with the new event detectors.

For further details about EEM 3.2 features, see the Embedded Event Manager 3.2 document.
