Port Connectivity Verification (asg_pingable

Port Connectivity Verification (asg_pingable_hosts)

Description

The Port Connectivity Verification feature makes sure that 61000/41000 Security System ports are connected to their hosts. When this feature is enabled, the system automatically adds a predefined value (default=50) to the Chassis Grade.

When Port Connectivity Verification detects a host connectivity error, this value is subtracted from the Chassis Grade. The system continuously runs connectivity tests at a predefined interval (Default = 4 seconds). You can change the interval with the pingable_hosts enable -i <interval> command.

Notes and Limitations

Port Connectivity Verification is not supported for VSX
Port Connectivity Verification only supports IPv4 addresses
A port is considered to be down when all connected hosts fail to respond to pings

Syntax

pingable_hosts --help p

pingable_hosts status

pingable_hosts load_ips

pingable_hosts disable

pingable_hosts enable

Parameter	Description
--help	Show commands and syntax
status	Show Port Connectivity Verification status and parameters
load_ips	Load
disable	Disable Port Connectivity Verification
enable	Enable Port Connectivity Verification and configure options
-i <interval>	Enter a verification interval in seconds (Default = 4)
-monitor	Enable the monitor only mode, which does not change the Chassis grade if connectivity verification detects an error.

Notes:

asg stat shows the Pingable Posts and verification results in the bottom row for each Chassis.

The UP/Required column shows the verification status, not the number of pingable hosts up or required. The status means:
- 1 / 1 = OK
- 0 / 1 when one of the pingable hosts on the list fails to reply
Port Connectivity log files are stored at /var/log/pingable_hosts
The default Port Connectivity Verification value added to the Chassis Score is 50. To change this value, run
> set chassis high-availability factors pnote pingable_hosts <factor>
