Connectivity Guide

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 traffic 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 configurations 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. Configuring RoCE with VXLAN is similar to configuring RoCE without VXLAN.
When you configure VXLAN and span that across a VLT topology, apply the configuration on all interfaces across the VLT
topology where you want to support RoCE.
For more information about how to configure RoCE, see the Configure RoCE on the switch section.
Sample configuration of RoCE for VXLAN over VLT
The following describes a topology where RoCE is enabled with VXLAN over VLT. SW1 is configured 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 configured
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.
