negotiation priority

Function

The negotiation priority command configures the protocol that a MultiGE interface in auto-negotiation mode preferentially uses.

The undo negotiation priority command restores the default protocol that a MultiGE interface in auto-negotiation mode preferentially uses.

By default, a MultiGE interface in auto-negotiation mode preferentially uses IEEE 802.3bz.

Only multi-GE interfaces on the S5720-28X-PWH-LI-AC, S5720-28X-PWH-LI-ACF, S5732-H24UM2CC, S5732-H48UM2CC, S6720-32C-SI-AC, S6720-32C-SI-DC, S6720-32C-PWH-SI-AC, S6720-32C-PWH-SI, S6720-52X-PWH-SI, S6720-56C-PWH-SI-AC, and S6720-56C-PWH-SI support this command.

Parameters

Parameter	Description	Value
802.3bz	Configures IEEE 802.3bz as the protocol that a MultiGE interface in auto-negotiation mode preferentially uses.	-
mgbase-t	Configures Mgbase-t as the protocol that a MultiGE interface in auto-negotiation mode preferentially uses. NOTE: Only the S5732-H24UM2CC and S5732-H48UM2CC do not support this parameter.	-

Usage Guidelines

Usage Scenario

If the peer device supports 2.5 Gbit/s or 5 Gbit/s rate when the peer device connects to the MultiGE interface of Huawei switch and the peer device uses the proprietary protocol Mgbase-t of the Broadcom company, the MultiGE interface of the interconnected Huawei switch may fail to be enabled. You can configure Mgbase-t as the protocol that the MultiGE interface on the Huawei switch preferentially uses, so that the MultiGE interface can be properly enabled.

Example

# Configure Mgbase-t as the protocol that a MultiGE interface in auto-negotiation mode preferentially uses.
