Checking Ip Connections; Ping; Traceroute - Allied Telesis SwitchBlade x908 Series Software Reference Manual

Checking IP Connections

To verify connections between networks and network devices, use the ping (Packet Internet
Groper) and trace route functions on your device.

Ping

Ping tests the connectivity between two network devices to determine whether each network
device can "see" the other device. Echo request packets are sent to the destination addresses
and responses are displayed on the console.
If you can ping the end destination, then the physical, Layer 2 and Layer 3 links are functioning,
and any difficulties are in the network or higher layers.
If pinging the end destination fails, use traceroute to discover the point of failure in the route to
the destination.
To ping a device, use the command:
where WORD can be either the hostname or the IP address of the device you are trying to
reach.

Traceroute

You can use traceroute to discover the route that packets pass between two systems running
the IP protocol. Traceroute sends an initial UDP packets with the Time To Live (TTL) field in
the IP header set starting at 1. The TTL field is increased by one for every subsequent packet
sent until the destination is reached. Each hop along the path between two systems responds
with a TTL exceeded packet (ICMP type 11) and from this the path is determined.
To use traceroute, use the command:
where WORD can be either the hostname or the IP address of the device you are trying to
reach.
