802.3 capabilities
Except for Power-via-MDI information, the Brocade device will advertise the following 802.3 attributes
when LLDP is enabled on a global basis:
• Link aggregation information
• MAC/PHY configuration and status
• Maximum frame size
• Power-via-MDI information (not automatically advertised)
Link aggregation TLV
The link-aggregation time, length, value (TLV) indicates the following:
• Whether the link is capable of being aggregated
• Whether the link is currently aggregated
• The primary trunk port
Brocade devices advertise link aggregation information about standard link aggregation (LACP) as well
as static trunk configuration.
By default, link-aggregation information is automatically advertised when LLDP is enabled on a global
basis. To disable this advertisement, enter a command such as the following.
device(config)#no lldp advertise link-aggregation ports e 2/12

The link aggregation 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 ).
Link aggregation: not capable
MAC and PHY configuration status
The MAC and PHY configuration and status TLV includes the following information:
• Auto-negotiation capability and status
• Speed and duplex mode
• Flow control capabilities for auto-negotiation
• maximum port speed advertisement
• If applicable, indicates if the above settings are the result of auto-negotiation during link initiation or of
a manual set override action
The advertisement reflects the effects of the following CLI commands:
• speed-duplex
• flow-control
• gig-default
• link-config
By default, the MAC/PHY configuration and status information are automatically advertised when LLDP
is enabled on a global basis. To disable this advertisement, enter a command such as the following.
device(config)#no lldp advertise mac-phy-config-status ports e 2/4 to 2/12
