Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
LLDP-MED Fast Start Control
Syntax:
lldp fast-start-count < 1 - 10 >
An LLDP-MED device connecting to a switch port may use
the data contained in the MED TLVs from the switch to
configure itself. However, the
lldp refresh-interval
setting
(default: 30 seconds) for transmitting advertisements can
cause an unacceptable delay in MED device configuration.
To support rapid LLDP-MED device configuration, the
lldp
fast-start-count
command temporarily overrides the
refresh-
interval
setting for the
fast-start-count
advertisement interval.
This results in the port initially advertising LLDP-MED at
a faster rate for a limited time. Thus, when the switch detects
a new LLDP-MED device on a port, it transmits one LLDP
MED advertisement per second out the port for the duration
of the
fast-start-count
interval. In most cases, the default
setting should provide an adequate
fast-start-count
interval.
(Range:
1 - 10
seconds; Default:
5
seconds)
Note:
This global command applies only to ports on which a
new LLDP-MED device is detected. It does not override the
refresh-interval setting on ports where non-MED devices are
detected.
Advertising Device Capability, Network Policy, PoE Status
and Location Data
The medTlvEnable option on the switch is enabled in the default configuration
and supports the following LLDP-MED TLVs:
■
LLDP-MED capabilities: This TLV enables the switch to determine:
• whether a connected endpoint device supports LLDP-MED
• which specific LLDP-MED TLVs the endpoint supports
• the device class (1, 2, or 3) for the connected endpoint
This TLV also enables an LLDP-MED endpoint to discover what LLDP
MED TLVs the switch port currently supports.
■
network policy operating on the port to which the endpoint is connected
(VLAN, Layer 2 QoS, Layer 3 QoS)
■
PoE (MED Power-over-Ethernet)
