Use this page to initiate ping or trace route commands
to any IP address or hostname from this IBM® TS7700 cluster.
You can use these commands to test the efficiency of grid links and
the network system.
- Network Test
- The type of test to be performed from the accessing cluster.
Note: If
the
IP Address/Hostname is a domain name system
(DNS) address you must activate and configure a DNS server on the
Cluster network settings TS7700
Customer Information Center Cluster network settings page before
performing the test.
- The accessing cluster is identified to the right of this field
in this format:
"Cluster Nickname[Cluster ID]" (#Distributed Library Sequence Number)
- Possible values include:
- Ping
- Select this option to initiate a ping test against the IP Address
or Hostname entered in the IP Address/Hostname field.
- This option tests the length of time required for a packet of
data to travel from your computer to a specified host, and back again.
This option can test whether a connection to the target IP Address
or Hostname is enabled, the speed of the connection, and the "distance"
to the target.
- Traceroute
- Select this option to initiate a trace route test against the
IP Address or Hostname entered in the IP Address/Hostname field.
- This option traces the path a packet follows from the accessing
cluster to a target address and displays the number of times packets
are rebroadcast by other servers before reaching their destination.
Important: The Traceroute command is
intended for network testing, measurement, and management. It imposes
a heavy load on the network and should not be used during normal operations.
- IP Address/Hostname
- The target IP address or host name for the selected network test.
The value in this field can be an IP address in IPv4 or IPv6 format
or a fully qualified host name.
- A valid IPv4 address is 32 bits long, consists of four decimal
numbers, each ranging from 0 to 255, separated by periods, like:
98.104.120.12
- A valid IPv6 address is an 128-bit long hexadecimal value separated
into 16-bit fields by colons, like:
3afa:1910:2535:3:110:e8ef:ef41:91cf
Leading
zeros can be omitted in each field, so that :0003:
can
be written as :3:
. A double colon (::
)
can be used once per address to replace multiple fields of zeros.
For example, 3afa:0:0:0:200:2535:e8ef:91cf
can
be written as: 3afa::200:2535:e8ef:91cf
- A fully qualified host name is a domain name that uniquely and
absolutely names a computer. It is composed of the host name and the
domain name. The domain name is one or more domain labels that place
the computer in the DNS naming hierarchy. The host name and the domain
name labels are separated by periods and the total length of the hostname
cannot exceed 255 characters.
- Number of Pings
- Use this field to select the number of pings sent by the Ping command.
The range of pings available is 1-100. The default value is 4.
- This field is only displayed if the value in the Network
Test field is Ping.
- Start
- Click this button to begin the selected network test. This button
is disabled if required information is not yet entered on the page
or if the network test is in progress.
- Cancel
- Click this button to cancel a network test in progress. This button
is disabled unless a network test is in progress.
- Output
- This field displays the progress output resulting from the network
test command. Information retrieved by the web interface is displayed
in this field as it is received. You can scroll within this field
to view output that exceeds the space provided.
- The status of the network command is displayed in line with the Output field
label and right-justified above the Output field.
