- System Capabilities—Primary functions of the switch, and whether or
not these functions are enabled in the switch. The capabilities are
indicated by two octets. Bits 0 through 7 indicate Other, Repeater, Bridge,
WLAN AP, Router, Telephone, DOCSIS cable device, and station,
respectively. Bits 8 through 15 are reserved.
- 802.3 MAC-PHY—Duplex and bit rate capability and the current duplex
and bit rate settings of the sending device. It also indicates whether the
current settings are due to auto-negotiation or manual configuration.
- 802.3 Link Aggregation—Whether the link (associated with the port on
which the LLDP PDU is transmitted) can be aggregated. It also indicates
whether the link is currently aggregated, and if so, provides the
aggregated port identifier.
- 802.3 Maximum Frame Size—Maximum frame size capability of the
MAC/PHY implementation.
- Management IP Address—Management IP address of the switch.
STEP 4 Click Apply. The LLDP port settings are modified, and the Running Configuration is

Configuring LLDP MED Network Policy
LLDP Media Endpoint Discovery (LLDP MED) is an extension of LLDP that provides
the following additional capabilities to support media endpoint devices. Some of
the features of the LLDP MED network policy are:
• Enables the advertisement and discovery of network policies for real-time
applications such as voice and/or video.
• Device location discovery to allow creation of location databases and, in
the case of Voice over Internet Protocol (VoIP), Emergency Call Service
(E-911) by using IP Phone location information.
NOTE The switch automatically advertises the policy according to user configuration;
however, the user must also manually configure the switch to use that policy.
An LLDP MED network policy is a related set of configuration settings for a
specific real-time application such as voice or video. A network policy, if
configured, will be included into the outgoing LLDP packets to the attached LLDP
media endpoint device. The media endpoint device should send its traffic as
specified in the network policy that it receives.
