4. Software/Driver Configuration and Fine-tuning
4.1.
Testing connectivity with
ping
and
rping
Load the NIC, iWARP & core RDMA modules as mentioned in
After which, you will see two or four ethernet interfaces for the T5/T4 device. Configure them
with an appropriate ip address, netmask, etc. You can use the Linux
ping
command to test basic
connectivity via the T5/T4 interface. To test RDMA, use the
rping
command that is included in
the librdmacm-utils RPM:
Run the following command on the server machine:
[root@host~]# rping -s -a server_ip_addr -p 9999
Run the following command on the client machine:
[root@host~]# rping -c –Vv -C10 -a server_ip_addr -p 9999
You should see ping data like this on the client:
ping data: rdma-ping-0: ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqr
ping data: rdma-ping-1: BCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrs
ping data: rdma-ping-2: CDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrst
ping data: rdma-ping-3: DEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstu
ping data: rdma-ping-4: EFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuv
ping data: rdma-ping-5: FGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvw
ping data: rdma-ping-6: GHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwx
ping data: rdma-ping-7: HIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxy
ping data: rdma-ping-8: IJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz
ping data: rdma-ping-9: JKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyzA
