•
[traffic-class <traffic-class>]
which indicates the IP packets in a traffic class are routed via the defined
Nexthop in the routing table entry for that traffic-class. Default: local-default.
When using
ping
for fault isolation, you should first run it on the respective IP interface to verify that the local
LAN or WAN interface is up and running. Then, you should “ping” hosts and gateways further away. Round-
trip times and packet loss statistics are computed. If duplicate packets are received, they are not included in the
packet loss calculation, although the round trip time of these packets is used to calculate the minimum/aver-
age/maximum round-trip time numbers. When five ICMP echo requests packets have been sent and received,
a brief summary is displayed.
Example:
Testing connections with the
ping
command
The following example shows how to invoke the echo protocol to the destination host at IP address
172.16.1.10 by using the
ping
command from operator execution mode.
node>ping 172.16.1.10
Sending 5 ICMP echo requests to 172.16.1.10, timeout is 1 seconds:
Reply from 172.16.1.10: Time <10ms
Reply from 172.16.1.10: Time <10ms
Reply from 172.16.1.10: Time <10ms.

Ping statistics for 172.16.1.10:
Packets: Sent 5, Received 5, Lost 0 (0% loss),
RTT: Minimum <10ms, Maximum <10ms, Average <10ms
Debug ARP
You may use the
debug arp
and
show arp
commands to assist you in debugging IP connectivity and its cor-
responding interfaces.
Mode: Either operator or administrator execution
Traceroute
This procedure describes how to print the route (list of hops) packets take to the network host.
Step
Command
Purpose
1
node(cfg)# [no] debug arp
Enables or disables the ARP debug monitor.
2
node(cfg)# show arp
Summarizes the ARP information for each of the Ethernet ports.
Step
Command
Purpose
1
node#traceroute <ip_host>
[probe-count
<probe_count> ] [timeout
<seconds> ] [destination-
port <port_number> ] [min-
ttl <min_ttl> ] [max-ttl
<max_ttl> ] [verbose ]
[packet-size <packet-size> ]
[mtu ] [traffic-class <traffic-
class> ]
Prints the route that the packets take to the network host.
Optionally, a traffic-class can be specified in the ‘traceroute’ com-
mand. ‘traceroute’ follows the route of the specified traffic-class.
Default: local-default
