lldp enable
This command enables switch operation via LLDP.
The use of a negative form (no) of the command disables LLDP protocol usage by switch.
Syntax
[no] lldp enable
Parameters
The command contains no arguments.
Command mode
CONFIG
Example
ma4000(config)# lldp enable
lldp hold-multiplier
This command specifies the amount of time for the receiver to keep LLDP packets before dropping them.
This value will be transmitted to the receiving side in the LLDP update packets; and should be an increment for the LLDP timer. Thus, the lifetime of LLDP packets is calculated by the formula: TTL = min(65535, LLDP-Timer * LLDP-HoldMultiplier).
The use of a negative form (no) of the command sets the default value.
Syntax
lldp hold-multiplier <HOLD>
no lldp hold-multiplier
Parameters
<HOLD> – time, may take values [2 .. 10] seconds.
Default value
4 seconds
Command mode
CONFIG
Example
ma4000(config)# lldp hold-multiplier 5
lldp reinit
This command sets ninimum amount of time for the LLDP port to wait before LLDP reinitialization.
The use of a negative form (no) of the command sets the default value.
Syntax
lldp reinit <REINIT>
no lldp reinit
Parameters
<REINIT> – time, may take values [1 .. 10] seconds.
Default value
2 seconds
Command mode
CONFIG
Example
ma4000(config)# lldp reinit 3
lldp timer
This command specifies how frequently the device will send LLDP information updates.
The use of a negative form (no) of the command sets the default value.
Syntax
lldp timer <TIMER>
no lldp timer
Parameters
<TIMER> – time, may take values [5..32768] seconds.
Default value
30 seconds
Command mode
CONFIG
Example
ma4000(config)# lldp timer 60
lldp tx-delay
This commans specifies the delay between the subsequent LLDP packet transmissions caused by the changes of values or status in the local LLDP MIB database.
It is recommended that this delay be less than 0.25* LLDP-Timer.
The use of a negative form (no) of the command sets the default value.
Syntax
lldp tx-delay <TXDELAY>
no lldp tx-delay
Parameters
<TXDELAY> – time, may take values [1..8192] seconds.
Default value
2 seconds
Command mode
CONFIG
Example
ma4000(config)# lldp tx-delay 3
lldp lldpdu
This command sets the LLDP packet processing mode when LLDP is disabled.
The use of a negative form (no) of the command sets the default value (filtering).
Syntax
lldp lldpdu <MODE>
no lldp lldpdu
Parameters
<MODE> – LLDP packets processing mode:
- filtering – LLDP packets are filtered if LLDP is disabled on the switch;
- flooding – LLDP packets are transmitted if LLDP is disabled on the switch.
Command mode
CONFIG
Example
ma4000(config)# lldp lldpdu flooding
lldp mode
This command sets the operating mode of the LLDP protocol for a specific interface.
The use of a negative form (no) of the command sets the default value.
Syntax
lldp mode <MODE>
no lldp mode
Parameters
<MODE> – operation mode of LLDP on interface:
- disabled – denies operation via LLDP;
- transmit-only – allows only the transmission of packets via LLDP;
- receive-only – allows only the reception of packets via LLDP;
- transmit-receive – allows transmission and reception of packets via LLDP.
Default value
transmit-receive
Command mode
FRONT-PORT
Example
ma4000(front-port-all)# lldp mode receive-only
show lldp configuration
This command allows to view the LLDP configuration of all physical interfaces of the device or specified interfaces.
Syntax
show lldp configuration [front-port <RANGE>]
Parameters
<RANGE> – interface number. The range of values and numbering rules are described in Table 4.1. If you specify the value 'all' in the command, all interfaces of the given type will be specified.
You may specify the list of numbers using comma ( , ) or specify the range using hyphen ( - ).
