Tracing an IPv4 route

NOTE

This section describes the IPv4 traceroute command. For details about IPv6 traceroute, refer to “IPv6 traceroute” on page 114.

Use the traceroute command to determine the path through which a Brocade device can reach another device. Enter the command at any level of the CLI.

The CLI displays trace route information for each hop as soon as the information is received. Traceroute requests display all responses to a given TTL. In addition, if there are multiple equal-cost routes to the destination, the Brocade device displays up to three responses by default.
