9.6 Diagnostic Setup
The DSL device supports some useful diagnostic tools.
9.6.1 Ping Diagnostic
Ping operates by sending Internet Control Message Protocol (ICMP) echo request packets to the target
host and waiting for an ICMP response. In the process it measures the time from transmission to
reception (round-trip time) and records any packet loss.
9.6.2 Ping6 Diagnostic
IPv6 configuration is mostly the same as IPv4 configuration (please refer to 9.6.1 Ping Diagnostic). IPv4
uses only 32 bits for IP address space; IPv6 allows 128 bits for IP address space.

9.6.3 Traceroute Diagnostic
Traceroute is a computer network diagnostic tool for displaying the route (path) and measuring transit
delays of packets across an Internet Protocol (IP) network.
9.6.4 OAM Fault Management
–
Connectivity Verification
In order to isolate the ATM interface problems, you can use ATM OAM loopback cells to verify
connectivity between VP/VC endpoints, as well as segment endpoints within the VP/VC.
OAM F4 cells operate at the VP level. They use the same VPI as the user cells, however, they use two
different reserved VCIs, as follows:
VCI=3 Segment OAM F4 cells.
VCI=4 End-to-End OAM F4 cells.
OAM F5 cells operate at the VC level. They use the same VPI and VCI as the user cells. To distinguish
between data and OAM cells, the PTI field is used as follows:
PTI=100 Segment OAM F5 cells processed by the next segment.

PTI=101 End-to-End OAM F5 cells which are only processed by end stations terminating an ATM link.
