BLADEOS 6.5.2 Application Guide

Enabling and Disabling DCBX

When CEE is turned on, DCBX can be enabled and disabled on a per-port basis, using the following commands:

RS G8124(config)# [no] cee port <port alias or number> dcbx enable

Note – DCBX and vNICs (see “Virtual NICs” on page 153) are not supported simultaneously on the same G8124.

When DCBX is enabled on a port, Link Layer Detection Protocol (LLDP) is used to exchange DCBX parameters between CEE peers. Also, the interval for LLDP transmission time is set to one second for the first five initial LLDP transmissions, after which it is returned to the administratively configured value. The minimum delay between consecutive LLDP frames is also set to one second as a DCBX default.

Peer Configuration Negotiation

CEE peer configuration negotiation can be set on a per-port basis for a number of CEE features. For each supported feature, the administrator can configure two independent flags:

￿The advertise flag

When this flag is set for a particular feature, the switch settings will be transmit to the remote CEE peer. If the peer is capable of the feature, and willing to accept the G8124 settings, it will be automatically reconfigured to match the switch.

￿The willing flag

Set this flag when required by the remote CEE peer for a particular feature as part of DCBX signaling and support. Although some devices may also expect this flag to indicate that the switch will accept overrides on feature settings, the G8124 retains its configured settings. As a result, the administrator should configure the feature settings on the switch to match those expected by the remote CEE peer.
