Enhanced Transmission Selection (ETS) Commands
19-1 ets willing
This command is used to enable the Enhanced Transmission Selection (ETS) willing mode for the Data Center
Bridging eXchange Protocol (DCBX) on a specified interface. Use the no form of this command to disable willing mode.
ets willing
no ets willing
19-2 ets recommend
This command is used to configure the ETS Recommendation feature on a specified interface. This setting will be
translated to a DCBX ETS-Recommendation TLV. The TLV is encoded into each LLDP message and may be
transmitted by a system in order to indicate a recommendation on how ETS should be configured. Use the no form of
this command to revert to default setting.
ets recommend {bandwidth WEIGHT0 WEIGHT1 WEIGHT2 WEIGHT3 WEIGHT4 WEIGHT5 WEIGHT6
WEIGHT7 | cos-map COS-QUEUE COS-VALUE [, | -]}
no ets recommend [bandwidth | cos-map]
Parameters
Parameters
None.
Default
Disabled.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 15.
Usage Guideline
The command is available for physical port configuration. Use this command to
enable the willing mode for ETS configuration when running DCBX, which indicates
that the interface is willing to accept configurations from a remote switch.
The Data Center Bridging eXchange Protocol (DCBX) is used by DCB devices to
exchange configuration information with directly connected peers. The protocol may
also be used for misconfiguration detection and for the configuration of the peer.
The Willing mode indicates that the local port has been administratively configured to
accept a configuration from the remote device. You need enable the Switch to
transmit LLDP DCBX ETS-Configuration TLVs to advertise the ETS settings and
negotiated with the peer to take the ETS willing (on) into effect.
You can use the mls qos scheduler ets interface mode command to configure the
scheduling mode to ETS and use the ets-queue bandwidth interface mode
command to assign bandwidth for every traffic classes.
Example
This example shows how to enable the ETS willing feature on interface
tenGigabitEthernet 1/0/1.
DXS-3600-32S#configure terminal
DXS-3600-16S(config)#interface tenGigabitEthernet 1/0/1
DXS-3600-32S(config-if)# ets willing
DXS-3600-32S(config-if)#
bandwidth WEIGHT0-7 Specifies the recommended bandwidth for Traffic Classes 0 to 7. It is required to
specify 8 values for Traffic Classes 0 to 7 respectively. The sum of the bandwidth
assigned to a given port is required at all times to be equal to 100. An operation that
attempts to change the bandwidth will be rejected. The valid range is 0 to 100 (in
percentage). The value of zero stands for strict priority mode.
