request virtual-chassis device-reachability

Syntax

Description

Run a Virtual Chassis device reachability test. A Virtual Chassis device reachability test sends ping packets from one member of a Virtual Chassis to another member of a Virtual Chassis directly through the Virtual Chassis connections. The receiving Virtual Chassis member sends reply packets to confirm receipt of the ping packets from the sending device. The results of the test immediately provide information that is helpful in verifying connectivity between Virtual Chassis member devices.

Options

test-name `name`	Specify the name of the test. The name can be any single-word character string. Spaces are not allowed.
source-fpc `source-fpc-id`	Specify the FPC that sends the first ping message.
source-ip-address `source-ip-address`	Specify the source IP address that receives the ping message.
destination-device `device-id`	Specify the device in the Virtual Chassis that receives the ping message.
destination-fpc `destination-fpc-id`	Specify the FPC that receives the first ping message.
destination-ip-address `destination-ip-address`	Specify the destination IP address that receives the ping message.
probe-count `count`	(Optional) Specify the number of ping messages to send for the test. The count can be any number from 1 through 10. The default count is 5.
probe-interval `interval`	(Optional) Specify the time in seconds between the ping messages that are sent during the test. The interval can be any number from 1 through 3. The default interval is 1 second.
probe-pattern `pattern`	(Optional) Specify a payload pattern in the ping message. Enter the pattern in hexadecimal format.
test-count `count`	(Optional) Specify the number of times to run the test. The count can be any number from 1 through 3. The default count is 1.
test-interval `interval`	(Optional) Specify the time in seconds between tests when multiple tests are specified. The interval can be any number from 1 through 3. The default interval is 1.
