f Enable ETS on the interface.
OS10 (conf-if-eth1/1/1)# ets mode on
g Apply the qos-map for ETS congurations 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
Congure RoCE on the interfaces
The following example describes the steps that you need to perform to congure RoCE on the all the interfaces that the switch uses. This
conguration 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 trac 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 congurations 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. Conguring RoCE with VXLAN is similar to conguring RoCE without VXLAN. When you
congure VXLAN and span that across a VLT topology, apply the conguration on all interfaces across the VLT topology where you want to
support RoCE.
For more information about how to congure RoCE, see the Congure RoCE on the switch section.
Sample conguration of RoCE for VXLAN over VLT
The following describes a topology where RoCE is enabled with VXLAN over VLT. SW1 is congured 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 congured 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.
