Configuration manual

A port that receives an internally propagated configuration overwrites its local
configuration with the new parameter values.
When an auto-upstream port (besides the configuration source) receives and
overwrites its configuration with internally propagated information, one of the
following actions is taken:
• If the peer configuration received is compatible with the internally propagated
port configuration, the link with the DCBx peer is enabled.
• If the received peer configuration is not compatible with the currently
configured port configuration, the link with the DCBX peer port is disabled and
a syslog message for an incompatible configuration is generated. The network
administrator must then reconfigure the peer device so that it advertises a
compatible DCB configuration.
The configuration received from a DCBX peer or from an internally propagated
configuration is not stored in the switch’s running configuration.
On a DCBX port in an auto-upstream role, the PFC and application priority TLVs are
enabled. ETS recommend TLVs are disabled and ETS configuration TLVs are
enabled.
Auto-
downstream
The port advertises its own configuration to DCBx peers but is not willing to
receive remote peer configuration. The port always accepts internally propagated
configurations from a configuration source. An auto-downstream port that
receives an internally propagated configuration overwrites its local configuration
with the new parameter values.
When an auto-downstream port receives and overwrites its configuration with
internally propagated information, one of the following actions is taken:
• If the peer configuration received is compatible with the internally propagated
port configuration, the link with the DCBx peer is enabled.
• If the received peer configuration is not compatible with the currently
configured port configuration, the link with the DCBX peer port is disabled and
a syslog message for an incompatible configuration is generated. The network
administrator must then reconfigure the peer device so that it advertises a
compatible DCB configuration.
The internally propagated configuration is not stored in the switch’s running
configuration. On a DCBX port in an auto-downstream role, all PFC, application
priority, ETS recommend, and ETS configuration TLVs are enabled.
Configuration
source
The port is configured to serve as a source of configuration information on the
switch. Peer DCB configurations received on the port are propagated to other
DCBx auto-configured ports. If the peer configuration is compatible with a port
configuration, DCBx is enabled on the port.
On a configuration-source port, the link with a DCBx peer is enabled when the port
receives a DCB configuration that can be internally propagated to other auto-
configured ports.
The configuration received from a DCBX peer is not stored in the switch’s running
configuration.
