MES1000, MES2000 Ethernet Switches 103
Table 5.98 —EXEC mode commands
Request the information on erps general status or specified
ring status.
5.16.9 LLDP protocol configuration
The basic function of Link Layer Discovery Protocol (LLDP) is the exchange of information on status
and specifications between network devices. Information gathered with LLDP is stored on devices and can
be requested by the master computer via SNMP protocol. Thus, this information allows to model the
network topology on the master computer.
Switches support transmission of standard and optional parameters, such as:
Device name and description
Port name and description
MAC/PHY information
etc.
Global configuration mode commands
Command line request in global configuration mode appears as follows:
console(config)#
Table 5.99 —Global configuration mode commands
Enable LLDP utilization by the switch.
Disable LLDP utilization by the switch.
Define the frequency of LLDP information updates
transmission by the device.
Restore the default value.
lldp hold-multiplier number
Define the amount of time for the receiving device to keep
LLDP packets before dropping them.
This value will be transmitted to the receiving side in LLDP
update packets; is a divisibility for LLDP timer. Thus, LLDP
packet lifetime is calculated by the equation TTL = min(65535,
LLDP-Timer * LLDP-HoldMultiplier)
Restore the default value.
Minimum amount of time, that LLDP port will wait before LLDP
reinitialization.
Restore the default value.
Define the delay between the subsequent LLDP packet
transmissions, initiated by changes of values or status in local
LLDP MIB database.
It is recommended to set this delay less than 0.25*
LLDP-Timer.
Restore the default value.
lldp lldpdu
{filtering | flooding}
Define the LLDP packet processing mode, when LLDP is
disabled on the switch:
- filtering—LLDP packets are filtered, if LLDP is disabled on the
switch
- flooding—LLDP packets are transmitted, if LLDP is disabled
on the switch
Restore the default value.
lldp med fast-start repeat-
count number
Set the PDU LLDP repetition quantity for quick start defined by
LLDP-MED.
no lldp med fast-start
repeat-count
Restore the default value.
lldp med network-policy
number application
number: (1..32);
application: (voice,
Define the rule for network-policy parameter (device network
policy). This parameter is optional for LLDP MED protocol
