Using LLDP

Note that using the keyword all may cause undesirable effects on some ports. The configuration
will be applied to all ports, however, the ports that are not members of any VLAN will not send VLAN
name advertisements.Maximum frame size
Maximum frame size TLV
The maximum frame size TLV provides the maximum 802.3 frame size capability of the port. This
value is expressed in octets and includes the four-octet Frame Check Sequence (FCS). The default
maximum frame size is 1522. The advertised value may change depending on whether the
aggregated-vlan or jumbo CLI commands are in effect.
By default, the maximum frame size is automatically advertised when LLDP is enabled on a global
basis. To disable this advertisement, enter a command such as the following.
Brocade(config)#no lldp advertise max-frame-size ports e 2/4 to 2/12
The maximum frame size advertisement will appear similar to the following on the remote device,
and in the CLI display output on the Brocade device (show lldp local-info).
Maximum frame size: 1522 octets
Syntax: [no] lldp advertise max-frame-size ports ethernet port list | all
For port list, specify the ports in the format [slotnum/]portnum, where slotnum is required on
chassis devices only. You can list all of the ports individually, use the keyword to to specify a range
of ports, or a combination of both. To apply the configuration to all ports on the device, use the
keyword all instead of listing the ports individually.
Note that using the keyword all may cause undesirable effects on some ports. The configuration
will be applied to all ports, however, the ports that are not members of any VLAN will not send VLAN
name advertisements.Maximum frame size
Displaying LLDP statistics and configuration settings
You can use the following CLI show commands to display information about LLDP settings and
statistics:
• show lldp – Displays a summary of the LLDP configuration settings.
• show lldp statistics – Displays LLDP global and per-port statistics.
• show lldp neighbors – Displays a list of the current LLDP neighbors.
• show lldp neighbors detail – Displays the details of the latest advertisements received from
LLDP neighbors.
• show lldp local-info – Displays the details of the LLDP advertisements that will be transmitted
on each port.
LLDP configuration summary
To display a summary of the LLDP configuration settings on the device, enter the show lldp
command at any level of the CLI.
The following shows an example report.
