Using a DNS Name To Initiate a Trace Route
EXAMPLE:
Suppose you want to trace the route from a Foundry Layer 2 Switch to a remote server identified as NYC02 on
domain newyork.com. Because the newyork.com domain is already defined on the Layer 2 Switch, you need to
enter only the host name, NYC02, as noted below.
USING THE CLI
FastIron# traceroute nyc02
Syntax: traceroute <host-ip-addr> [maxttl <value>] [minttl <value>] [numeric] [timeout <value>]
[source-ip <ip addr>]
The only required parameter is the IP address of the host at the other end of the route. See the Foundry Switch
and Router Command Line Interface Reference for information about the parameters.
After you enter the command, a message indicating that the DNS query is in process and the current gateway
address (IP address of the domain name server) being queried appear on the screen:
Type Control-c to abort
Sending DNS Query to 209.157.22.199
Tracing Route to IP node 209.157.22.80
To ABORT Trace Route, Please use stop-traceroute command.
Traced route to target IP node 209.157.22.80:
IP Address
207.95.6.30
NOTE: In the above example, 209.157.22.199 is the IP address of the domain name server (default DNS
gateway address), and 209.157.22.80 represents the IP address of the NYC02 host.
