LLDP System Commands

See the 7705 SAR Interface Configuration Guide, ‟7705 SAR Interfaces”, for LLDP Ethernet port commands.

lldp

Syntax

lldp

Context

config>system

Description

This command enables the context to configure system-wide Link Layer Discovery Protocol (LLDP) parameters.

message-fast-tx

Syntax

message-fast-tx time

no message-fast-tx

Context

config>system>lldp

Description

This command configures the interval between LLDPDU transmissions by the LLDP agent during a fast transmission period.

The fast transmission period begins when a new neighbor is detected. During the fast transmission period, LLDPDUs are transmitted at shorter intervals than the standard tx-interval to ensure that more than one LLDPDU is sent to the new neighbor. The first transmission occurs as soon as the new neighbor is detected. The length of the fast transmission period is determined by the number of LLDPDU transmissions (configured by the message-fast-tx-init command) and the interval between them.

The no form of the command reverts to the default value.

Default

1

Parameters

time

specifies the interval between LLDPDU transmissions in seconds

Values

1 to 3600

message-fast-tx-init

Syntax

message-fast-tx-init count

no message-fast-tx-init

Context

config>system>lldp

Description

This command configures the number of LLDPDUs to send during a fast transmission period.

The fast transmission period begins when a new neighbor is detected. During the fast transmission period, LLDPDUs are transmitted at shorter intervals than the standard tx-interval to ensure that more than one LLDPDU is sent to the new neighbor. The first transmission occurs as soon as the new neighbor is detected. The length of the fast transmission period is determined by the number of LLDPDU transmissions and the interval between them (configured by the message-fast-tx command).

The no form of the command reverts to the default value.

Default

4

Parameters

count

specifies the number of LLDPDUs to send during the fast transmission period

Values

1 to 8

notification-interval

Syntax

notification-interval time

no notification-interval

Context

config>system>lldp

Description

This command configures the minimum time between change notifications. A change notification is a trap message sent to SNMP whenever a change occurs in the database of LLDP information.

The no form of the command reverts to the default value.

Default

5

Parameters

time

specifies the minimum time, in seconds, between change notifications

Values

5 to 3600

reinit-delay

Syntax

reinit-delay time

no reinit-delay

Context

config>system>lldp

Description

This command configures the time before reinitializing LLDP on a port.

The no form of the command reverts to the default value.

Default

2

Parameters

time

specifies the time, in seconds, before reinitializing LLDP on a port

Values

1 to 10

tx-credit-max

Syntax

tx-credit-max count

no tx-credit-max

Context

config>system>lldp

Description

This command configures the maximum number of consecutive LLDPDUs that can be transmitted at any time.

The no form of the command reverts to the default value.

Default

5

Parameters

count

specifies the maximum number of consecutive LLDPDUs transmitted

Values

1 to 100

tx-hold-multiplier

Syntax

tx-hold-multiplier multiplier

no tx-hold-multiplier

Context

config>system>lldp

Description

This command configures the multiplier of the transmit interval defined by the tx-interval command.

The transmit interval time multiplied by the tx-hold-multiplier is the TTL value in the LLDPDU. The TTL value determines the amount of time the receiving device retains LLDP packet information in local information databases before discarding it.

The no form of the command reverts to the default value.

Default

4

Parameters

multiplier

specifies the multiplier of the transmit interval

Values

2 to 10

tx-interval

Syntax

tx-interval interval

no tx-interval

Context

config>system>lldp

Description

This command configures the LLDP transmit interval time.

The no form of the command reverts to the default value.

Default

30

Parameters

interval

specifies the LLDP transmit interval time in seconds

Values

5 to 32768
