f Enable ETS on the interface.
OS10 (conf-if-eth1/1/1)# ets mode on
g Apply the qos-map for ETS congurations on the interface.
OS10 (conf-if-eth1/1/1)# qos-map traffic-class 2Q
h Enable PFC on the interface.
OS10 (conf-if-eth1/1/1)# priority-flow-control mode on
Congure RoCE on the interfaces
The following example describes the steps that you need to perform to congure RoCE on the all the interfaces that the switch uses. This
conguration example uses priority 3 for RoCE.
1 Enter in to the INTERFACE mode and enter the no shutdown command.
OS10# configure terminal
OS10 (config)# interface ethernet 1/1/1
OS10 (conf-if-eth1/1/1)# no shutdown
2 Change the switch port mode to trunk mode.
OS10 (conf-if-eth1/1/1)# switchport mode trunk
3 Change the access VLAN management.
OOS10 (conf-if-eth1/1/1)# switchport access vlan 1
4 Specify the allowed VLANs on the trunk port.
OS10 (conf-if-eth1/1/1)# switchport trunk allowed vlan 55
5 Apply the policy-map to the interface.
OS10 (conf-if-eth1/1/1)# service-policy input type network-qos pfcdot1p3
6 Apply the queuing policy to egress trac on the interface.
OS10 (conf-if-eth1/1/1)# service-policy output type queuing 2Q
7 Enable enhanced transmission selection (ETS) on the interface.
OS10 (conf-if-eth1/1/1)# ets mode on
8 Apply the service policy with dot1p trust and ETS congurations on the interface.
OS10 (conf-if-eth1/1/1)# qos-map traffic-class 2Q
9 Enable PFC on the interface.
OS10 (conf-if-eth1/1/1)# priority-flow-control mode on
RoCE for VXLAN over VLT
OS10 supports RoCE for VXLAN in a VLT setup. Conguring RoCE with VXLAN is similar to conguring RoCE without VXLAN. When you
congure VXLAN and span that across a VLT topology, apply the conguration on all interfaces across the VLT topology where you want to
support RoCE.
For more information about how to congure RoCE, see the Congure RoCE on the switch section.
Sample conguration of RoCE for VXLAN over VLT
The following describes a topology where RoCE is enabled with VXLAN over VLT. SW1 is congured as VTEP1 and is the upstream switch
that connects to the outer network. VLT peer 1 and VLT peer 2 from a VLT topology which is also congured as VTEP 2. A top-of-rack
(ToR) switch is connected to the VLT peers through a VLT port channel. The ToR is the downstream switch for end devices, such as,
virtual machines.
