Debug Arp; Traceroute - Patton electronics SmartWare R.3.20 Software Configuration Manual

SmartWare Software Configuration Guide
• [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 for fault isolation, you should first run it on the respective IP interface to verify that the local
ping
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

Debug ARP

You may use the

responding interfaces.
Mode: Either operator or administrator execution
Step Command
1 node (cfg)# [no] debug arp
2 node (cfg)# show arp

Traceroute

This procedure describes how to print the route (list of hops) packets take to the network host.

Enables or disables the ARP debug monitor.
Summarizes the ARP information for each of the Ethernet ports.
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.
