Step 4. Examine the GID table.

# cat /sys/class/infiniband/mlx4_0/ports/2/gids/0

fe80:0000:0000:0000:0202:c9ff:fe08:e811

# cat /sys/class/infiniband/mlx4_0/ports/2/gids/1

3.1.6.2.11Running an - ibv_rc_pingpong Test on the VLAN

Step 1. Start the server.

# ibv_rc_pingpong -g 1 -i 2

local address: LID 0x0000, QPN 0x04004f, PSN 0xbdde2c, GID fe80::202:c900:708:e799

remote address: LID 0x0000, QPN 0x08004f, PSN 0xc9d800, GID fe80::202:c900:708:e811

8192000 bytes in 0.01 seconds = 4824.50 Mbit/sec

1000 iters in 0.01 seconds = 13.58 usec/iter

Step 2. Start the client.

# ibv_rc_pingpong -g 1 -i 2 sw419

local address: LID 0x0000, QPN 0x08004f, PSN 0xc9d800, GID fe80::202:c900:708:e811

remote address: LID 0x0000, QPN 0x04004f, PSN 0xbdde2c, GID fe80::202:c900:708:e799

8192000 bytes in 0.01 seconds = 4844.83 Mbit/sec

1000 iters in 0.01 seconds = 13.53 usec/iter

3.1.6.2.12Defining Ethernet Priority (PCP in 802.1q Headers)

Step 1. Define ethernet priority on the server.

# ibv_rc_pingpong -g 1 -i 2 -l 4

local address: LID 0x0000, QPN 0x1c004f, PSN 0x9daf6c, GID fe80::202:c900:708:e799

remote address: LID 0x0000, QPN 0x1c004f, PSN 0xb0a49b, GID fe80::202:c900:708:e811

8192000 bytes in 0.01 seconds = 4840.89 Mbit/sec

1000 iters in 0.01 seconds = 13.54 usec/iter

Step 2. Define ethernet priority on the client.

# ibv_rc_pingpong -g 1 -i 2 -l 4 sw419

local address: LID 0x0000, QPN 0x1c004f, PSN 0xb0a49b, GID fe80::202:c900:708:e811

remote address: LID 0x0000, QPN 0x1c004f, PSN 0x9daf6c, GID fe80::202:c900:708:e799

8192000 bytes in 0.01 seconds = 4855.96 Mbit/sec

1000 iters in 0.01 seconds = 13.50 usec/iter
