HAPTER 3: CUDAVIEW DESKTOP TOOLS
Timeout Number of seconds to wait for a response to a probe
packet. The values range from 1 to 30. The default is 1.
Note that a trace consists of a series of transmitted probe
packets.
Intial TTL
Initial time-to-live (TTL) value in the number of hops,
enabling you to bypass the initial (often well known)
portion to a path. You can configure the trace to ignore
hosts that are less than the specified number of hops away
from your Cuda 12000. The values range from 0,
indicating no initial TTL, to 255. The default is 1.
Maximum TTL Maximum TTL value in the number of hops. When the
Cuda 12000 send a trace route packet, the Cuda 12000
sets the TTL value in the packet to the value you specify.
Each time a router forwards the packet, the router
decrements this value by one. Routers discard packets that
have a TTL to zero. Values range from 1 to 255. The
default is 30.
Source Address
Source IP address in outgoing probe packets on the Cuda
12000. By default, the source IP address is the IP address
of the interface that the Cuda 12000 sends the probe
packet. If your Cuda 12000 has more than one IP address,
this argument enables you to override the default source
address.
UDP Port
Base UDP port number on the destination host that the
trace route sends probe packets. Values range from 1 to
65535. The default is 33434.
Trace route assumes that no other processes on the
destination host use UDP port numbers in the range of
base to base + nhops -1. For example, if the base is 33434,
then the route uses a UDP port in the range:
33434 to 33434 + nhops -1
If another process listens on a port in this range, you can
use this argument to specify a new base UDP port number,
thereby configuring an unused port range.
DS (TOS) Field
Type-of-service (TOS) value in probe packets. The TOS field
determines if different TOS values take different paths.
Useful values are 16 (low delay) and 8 (high throughput).
The value must be a decimal integer in the range from 0 to
255. The default is 0.
