This LLDP TLV is used to advertise Priority Flow Control (PFC) configuration.
The various configuration parameters are:
| Field | Description |
|---|---|
| TLV Type | Size: 7 bits. Describes the Type of this TLV. This value is always 127 as this is a custom TLV. |
| TLV Information String Length | Size: 9 bits. This field indicates the size of the TLV information being passed. For this TLV this value is six (6). |
| 802.1 OUI | Size: 3 octets. The Organizationally Unique Identifier (OUI) assigned to the organization. This value is always 00-80-C2 for this TLV. |
| 802.1 Subtype | Size: 1 octet. This is an internally defined subtype. Its value is always eleven (11). This is assigned and managed by the organization. |
| Willing | Size: 1 bit. When set to one (1), it indicates that the station is willing to accept configuration from the remote peer. Set to zero (0) when the station is not willing to change its configuration. |
| MBC | Size: 1 bit. When set to zero (0), it indicates that the station is capable of bypassing MACsec processing when MACsec is disabled. When set to one (1), the station indicates that it is not capable of bypassing MACsec processing when MACsec is disabled. MACSec and MBC are not supported on SLX-OS, and this bit is disregarded. |
| Reserved | Size: 2 bits. Reserved for future use and is not used. |
| PFC Cap | Size: 4 bits. A 4 bit unsigned integer value. Indicates the device's limitation of how many traffic classes May simultaneously support PFC. SLX-OS supports PFC on all eight (8) traffic classes. |
| PFC Enable |
Size: 1 octet. The PFC Enable bit vector of 8 bits, one per priority.
