Windows 2000 Administration in a Nutshell

Name

pathping

Synopsis

Combines the features of ping and tracert to trace packet loss due to routers over a routed path through an internetwork. pathping is new to Windows 2000 and gives additional information that neither of these commands provides.

Syntax

pathping [-n] [-h maxhops] [-g hostlist] [-p msec] [-q queries] [-w msec] 
[-t] [-R] [-r] target

Options

-g hostlist

Permits consecutive hosts to be separated by intermediate gateways along hostlist

-h maxhops

Specifies maximum number of hops to traverse (the default is 30 hops)

-n

Does not resolve IP addresses to hostnames

-p msec

Specifies how many milliseconds to wait between consecutive pings (default is 250 msec, or 0.25 sec)

-q queries

Specifies number of queries issued to each host along the route (default is 100 queries)

-R

Checks which routers support Resource Reservation Setup Protocol (RSVP)

-T

Checks which routers do not have layer-2 priority configured

-w msec

Specifies how many milliseconds to wait for a reply (default is 3,000 msec or 3 seconds)

target

Identifies hostname or IP address of remote target host

Examples

Use pathping to check for congestion along the route from test.mtitcanada.com to www.gov.mb.ca:

                     pathping -n www.gov.mb.ca Tracing route to www.gov.mb.ca [198.163.12.46] over a maximum of 30 hops: 0 205.200.52.64 1 205.200.52.1 2 205.200.52.6 3 205.200.28.66 4 205.200.27.54 5 192.35.252.242 6 198.163.12.46 Computing statistics for 150 seconds...
