Table 275 General LLDP CLI Parameters
Parameter Input Type Permitted Values Description
tx-interval Number 5-3600 The interval, in seconds, at which LLDP
frames are transmitted. The default
value is 30.
hold-
multiplier Number 2-10 The TTL Multiplier, which is multiplied
by the Transmit Interval to determine
the TTL, in seconds, of LLDP frames. The
default value is 4.
notif-interval Number 5-3600 The interval, in seconds, between
transmission of LLDP notifications during
normal transmission periods. The
default value is 30.
Displaying the General LLDP Parameters (CLI)
To display the general LLDP parameters, enter the following command in root view:
root> ethernet lldp configuration-scalers-show
The following information is displayed:
•
Message Tx Interval - The interval, in seconds, at which LLDP frames are transmitted, as defined by
the ethernet lldp tx-interval-set tx-interval command. The default value is 30.
•
Message Tx Hold Multiplier - The TTL Multiplier, as defined by the
ethernet lldp tx-hold-
multiplier-set hold-multiplier
command. The TTL Multiplier is multiplied by the Transmit Interval to
determine the TTL, in seconds, of LLDP frames. The default value is 4.
•
Reinit Delay - The minimum time, in seconds, the system waits after the LLDP Admin status becomes Disabled
until it will process a request to reinitialize LLDP. In this release, this parameter is set at 2.
•
Notification Interval - The interval, in seconds, between transmission of LLDP notifications during normal
transmission periods, as defined by the
ethernet lldp notif-interval-set notif-
interval
command. The default value is 30.
•
Tx Credit Max - The maximum number of consecutive LLDPDUs that can be transmitted at any one time. In
this release, the Tx Credit Max is set at 5.
•
Message Fast Tx - The interval, in seconds, at which LLDP frames are transmitted during fast transmission
periods, such as when the unit detects a new neighbor. In this release, this parameter is set at 1.
•
Message Fast Init - The initial value used to initialize the variable which determines the number of
transmissions that are made during fast transmission periods. In this release, this parameter is set at 4.
The following commands set the Transmit Interval to 50 seconds with a TTL Multiplier of 5. This produces a TTL of
4 minutes and 10 seconds.
