4-20 Discovery Protocol Configuration
Auto-Neg Supported/Enabled IEEE 802.3 Extensions MAC-PHY Configuration/Status TLV. Auto-
negotiation supported and enabled settings should be the same on the
two systems attached to the same link.
Auto-Neg Advertised IEEE 802.3 Extensions MAC-PHY Configuration/Status TLV. Lists the
configured advertised values on the port.
Operational Speed/Duplex/
Type
IEEE 802.3 Extensions MAC-PHY Configuration/Status TLV. Lists the
operational MAU type, duplex, and speed of the port. If the received TLV
indicates that auto-negotiation is supported but not enabled, these values
will be used by the port.
Max Frame Size (bytes) IEEE 802.3 Extensions Maximum Frame Size TLV. Value indicates
maximum frame size capability of the device’s MAC and PHY. In normal
mode, max frame size is 1522 bytes. In jumbo mode, max frame size is
10239 bytes.
Vlan Id IEEE 802.1 Extensions Port VLAN ID TLV. Value is port VLAN ID (pvid).
LAG Supported/Enabled/Id IEEE 802.3 Extensions Link Aggregation TLV. Values indicate whether the
link associated with this port can be aggregated, whether it is currently
aggregated, and if aggregated, the aggregated port identifier.
Protocol Id IEEE 802.1 Extensions Protocol Identity TLV. Values can include
Spanning tree, LACP, and GARP protocols and versions. Only those
protocols enabled on the port are displayed.
ECS ELIN LLDP-MED Extensions Location Identification TLV. Emergency Call
Services (ECS) Emergency Location Identification Number (ELIN) is
currently the only type supported. Value is the ELIN configured on this
port.
PoE Device LLDP-MED Extensions Extended Power via MDI TLV. Displayed only
when a port has PoE capabilities. Value is the Power Type of the device.
On a switch port, the value is Power Sourcing Entity (PSE).
PoE Power Source LLDP-MED Extensions Extended Power via MDI TLV. Displayed only
when a port has PoE capabilities. Value can be primary or backup,
indicating whether the PSE is using its primary or backup power source.
PoE MDI Supported/Enabled IEEE 802.3 Extensions Power via MDI TLV. Displayed only when a port
has PoE capabilities. Indicates whether sending the Power via MDI TLV is
supported/enabled. Value can be yes or no.
PoE Pair Controllable/Used IEEE 802.3 Extensions Power via MDI TLV. Displayed only when a port
has PoE capabilities. Indicates whether pair selection can be controlled on
the given port (refer to RFC 3621). Value for Controllable can be true or
false. Value of Used can be signal (signal pairs only are in use) or spare
(spare pairs only are in use).
PoE Power Class IEEE 802.3 Extensions Power via MDI TLV. Displayed only when a port
has PoE capabilities. Indicates the power class supplied by the port. Value
can range from 0 to 4.
PoE Power Limit (mW) LLDP-MED Extensions Extended Power via MDI TLV. Displayed only
when a port has PoE capabilities. Indicates the total power the port is
capable of sourcing over a maximum length cable, based on its current
configuration, in milli-Watts.
PoE Power Priority LLDP-MED Extensions Extended Power via MDI TLV. Displayed only
when a port has PoE capabilities. Indicates the power priority configured
on the port. Value can be critical, high, or low.
