Verifying Communications within the Fabric

Verifying Communications within the Fabric

You can verify the communications within the fabric by running the clic_probe command, which is described below. You can also use clic_probe to verify the status of specific adapters.

You should also check your /etc/hosts file—when you are using files for host name look up—to ensure that the entries for all of the systems are in the correct format: the official host name, which is the full domain extended host name, and any alias names. For example:

IP_address bently6.corp3.com bently6

IP_address bently4.corp7.com test1

IP_address bently2.corp4.com test3

The clic_probe Command

Run the clic_probe command to send 256-byte packets to verify the link out to and back from a specific destination, optionally using a specific adapter for the verification. The destination can be either a node or a switch (if a switch is part of the fabric).

If you include /opt/clic/bin in your PATH statement, you can run the command as it is shown below. Otherwise, you must include /opt/clic/bin as part of the command name (that is, /opt/clic/bin/clic_probe).

You do not have to be logged in as root to run this command.

The syntax is as follows:

clic_probe node_name [-cadapter_ID]

[-cadapter_ID -rVRID switch_hopcount] [-l-cadapter_ID] [-s-cadapter_ID] [-ppacket_count] [-?]

Note that some of the lines in the above syntax are indented for readability purposes only. When you actually type the command, you do not indent anything.

The command parameters are as follows:

•node_name specifies the node you want to verify. This value is conditionally required—you must specify it when you are verifying traffic to a remote node, unless you use the -rparameter (described below).

•-cspecifies that you want to use the adapter identified by adapter_ID for the verification.

•-rspecifies that VRID switch_hopcount is the routing information for the adapter. To determine the VRID and switch_hopcount to specify, first run the clic_stat -d VRID command (see “The clic_stat Command” on page 101). Note that if you specify this parameter (-rVRID switch_hopcount), you must also specify the -cadapter_ID parameter (described above).
