• 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
The MAC/PHY configuration 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
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.
NOTE
On 48GC modules in non-jumbo mode, the maximum size of ping packets is 1486 bytes and the
maximum frame size of tagged traffic is no larger than 1581 bytes.
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.
device(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
).
