LLDP

lldp-show

This command is used to display Link Layer Discovery Protocol (LLDP) information on the switch. Link Layer Discovery Protocol (LLDP) allows Ethernet network devices such as switches and routers to receive and transmit device-related information to directly connected devices on the network that are also using the protocols, and to store the information that is learned about other devices.

Syntax   lldp-show local-port local-port-number chassid-id chassis-id-string port-id port-id-string

Specify any of the following options:

local-port local-port-number

Specifies the local port where the LLDP packet is received.

chassis-id chassis-id-string

Specifies the chassis ID of the switch.

port-id port-id-string

Specifies the port of the switch sending the LLDP packet.

Formatting Options

format fields-to-display

Display output using a specific parameter. Use all to display all possible output.

parsable-delim character

Display output formatted for machine parsing using a specified delimiter.

sort-asc

Display output in ascending order.

sort-desc

Display output in descending order.

show dups

Display duplicate entries in the output.

layout vertical|horizontal

Format the output in a vertical or horizontal layout.

show-interval seconds-interval

Repeat the show command at a specified interval.

show-headers|
no-show-headers

Display column headers or not.

limit-output number

Limit the display output to a specific number of entries.

count-output

Display the number of entries in the output. This is useful with vRouter show commands.

unscaled

Display full values in the output instead of scaled approximate values.

raw-int-values

Display integer values instead of mapped values

sum-by

Aggregate output by specific parameters. If sum-by fields are specified, records that have the same value in sum-by fields are combined and displayed as one aggregate record. NOTE: This option is only available for show commands that collect statistics such as connection-stats-show.

Defaults   None

Access   CLI

History   Command introduced in nvOS Version 2.0

Usage   Use this command to display LLDP information on the switch.

Examples  To display all LLDP information, use the following command:

CLI network-admin@switch > lldp-show
