Tracing a Packet’s Path at the Remote Access Concentrator

You can use the

ping -t

(traceroute) superuser command at the Remote Access

Concentrator console to trace the path of a packet from the local host to the

destination host and back, displaying information about each router in the path.

This option lets you see whether a packet arrived at and/or returned from its

remote destination, and if not, where it stopped. This option is based on the

traceroute facility, described in RFC 1493. For more information about using the

ping -t

command, refer to the Managing Remote Access Concentrators Using

Command Line Interfaces.

The

ping -t

command displays the following information:

Dir The direction in which the ICMP packet is heading.

The >>> symbols indicate an outbound packet heading toward the

ping –t

destination. The <<< symbols indicate a return packet heading

back towards the

ping –t

source. The *** symbols indicate that a router

could not forward the packet. In this case, the router discards the packet

and

ping –t

terminates.

Router The IP address of the router interface over which the outbound or return

packet was forwarded.

Hops The number of routers that the outbound or return packet has crossed. If

the count skips a hop (for example, goes from 4 to 6), a traceroute

message was lost, probably due to network congestion.

Speed The speed, in bits per second, of the interface over which the outbound

or return packet was forwarded. If the packet could not be forwarded,

ping –t

displays a zero in this field.

MTU The maximum transmission unit (in bytes) of the interface over which

the outbound or return packet was forwarded. The MTU is the largest

packet size the interface can forward without fragmenting the packet. If

the packet cannot be forwarded because its size exceeds the MTU and

its header indicates not to fragment,

ping –t

displays a zero in this field.
