Configuration Guide
VIII. Configuring the operating mode of a GE interface
GE optical interfaces provide two operating modes: negotiation and force. In
negotiation mode, the interface chip checks negotiation code, negotiating the format of
the PAUSE frame and the peer state (that is, whether it is faulty). In force mode, no
negotiation stream is present on the line. The interface chip decides whether an
interface can be brought up depending on how much light intensity it reads.
You must set the two ends to work in the same operating mode. Any inconsistency can
prevent the interface adopting negotiation mode from going up.
Perform the following configuration in GE interface view.
Table 2-8 Configure the operating mode of the GE interface
Configure the GE interface to operate in force mode.
Restore the default.
The default operating mode is negotiation.
IX. Configuring the operating mode of an Ethernet interface
Perform the following configuration in Ethernet interface.
Table 2-9 Configure the operating mode of the Ethernet interface
Set the operating mode of the Ethernet interface to
promiscuous.
Disable the Ethernet interface to operate in
promiscuous mode.
By default, the Ethernet interface is operating in non-promiscuous mode.
When the Ethernet interface is operating in promiscuous mode, it receives all correct
Ethernet packets without checking their MAC addresses, This mode is configured when
network listening applies.
After you enable the bridging function on an Ethernet interface and adds it to a
bridge-set, the interface enters promiscuous mode automatically. After removed from
the bridge-set, the interface enters non-promiscuous mode automatically.
