– 555 –
ets mode Use this command to set the ETS mode to negotiate capability through DCBX or by
forcing it to on state. Use the no form to restore the default setting.
Syntax
ets mode {auto | on}
no ets mode
auto – Negotiates ETS capability using DCBX. The operational capability of
ETS depends on the result of DCBX negotiations.
on – Forces ETS to enabled state.
Default Setting
Disabled
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
â—† Operator configuration of ETS is used only when the port is configured in DCBX
manual mode. When interoperating with other equipment in manual mode,
the peer equipment must be configured with identical ETS TCG queuing
algorithm, priority queue mapping, and minimum bandwidth requirements.
Ports configured in auto-upstream or auto-downstream DCBX roles receive
their ETS configuration from the configuration source and ignore any manually
configured information. Interfaces not enabled for ETS ignore received ETS
frames.
â—† ETS is configurable on full duplex interfaces only. To enable ETS on a LAG, the
member interfaces must have the same configuration.
Example
The following example sets port 5 to use ETX auto-negotiation mode.
Console(config)#interface ethernet 1/5
Console(config-if)#ets mode auto
Console(config-if)#
traffic-class algo Use this command to set the queue scheduling algorithm assigned to a traffic class
group. Use the no form to restore the default setting.
Syntax
traffic-class algo {strict | ets}
no traffic-class algo
strict - Processes all packets entering this interface using strict priority.
