MAC/PHY configuration status
The MAC/PHY configuration and status TLV includes the following information:
• Auto-negotiation capability and status
• Speed and duplex mode
• Flow control capabilities for auto-negotiation
• Port speed down-shift and 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.
PowerConnect(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 Dell PowerConnect device (show lldp local-info).
Syntax: [no] lldp advertise mac-phy-config-status ports ethernet <port-list> | all
For <port-list>, specify the ports in one of the following formats:
• PowerConnect B-Series FCX stackable switches – <stack-unit/slotnum/portnum>
You can list all of the ports individually, use the keyword to to specify ranges 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. For example, if you configure all ports to advertise their VLAN name, and
the configuration includes ports that are not members of any VLAN, the system will warn of the
misconfigurations on non-member VLAN 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
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.
PowerConnect(config)#no lldp advertise max-frame-size ports e 2/4 to 2/12
