Verifying RoCE v1 or v2 Functionality Through perftest Applications
This section shows how to verify RoCE v1 or v2 functionality through perftest
applications. In this example, the following server IP and client IP are used:
Server IP: 192.168.100.3
Client IP: 192.168.100.4
Verifying RoCE v1
Run over the same subnet and use RoCE v1 GID index.
Server# ib_send_bw -d qedr0 -F -x 0
Client# ib_send_bw -d qedr0 -F -x 0 192.168.100.3
Verifying RoCE v2
Run over the same subnet and use the proper RoCE v2 GID index.
Server# ib_send_bw -d qedr0 -F -x 1
Client# ib_send_bw -d qedr0 -F -x 1 192.168.100.3
Verifying RoCE v2 Through Different Subnets
To verify RoCE v2 through different subnets.
1.
Set the route configuration for the server and client using DCBX-PFC
configuration.
System Settings:
Server VLAN IP
: 192.168.100.3 and
Gateway :
192.168.100.1
Client VLAN IP
:
192.168.101.3 and
Gateway :
192.168.101.1
Server Configuration
:
#
/sbin/ip link add link p4p1 name p4p1.100 type vlan id 100
#
ifconfig p4p1.100 192.168.100.3/24 up
#
ip route add 192.168.101.0/24 via 192.168.100.1 dev p4p1.100
NOTE
If you are running through switch PFC configuration, use VLAN GIDs for
RoCE v1 or v2 through the same subnet.
NOTE
You must first configure the route settings for the switch and servers. On the
adapter, set the RoCE priority and DCBX mode using the HII or UEFI user
interface.
