NetScaler BLX configuration file

Contributed by:

A configuration file (blx.conf) is added to the Linux host as part of the NetScaler BLX installation. The blx.conf file has different parameters, which you can use to configure BLX.

By default, all the parameters are commented (prefixed with # symbol) in the BLX configuration file. You can uncomment (remove the prefix #) the parameter and set it to a custom value to enable a certain parameter.

The parameters in the blx.conf file are listed in the following table:

Parameter	Possible values	Default	Description
`worker-processes`	1 to 28	1	Number of worker processes to be started.
`cpu-yield`	yes, enable, or 1	Disabled	Configures CPU Yielding. When you enable CPU-yield, NSPPE yields CPU for other processes.
`core-dumps`	yes, enable, or 1	Disabled	Configures core dumps for BLX.
`syslog`	yes, enable, or 1	Disabled	Enables syslog to listen on port 514/UDP of the Linux host. BLX sends logs to syslog listening on port 514/UDP of the Linux host.
`ipaddress`	IP address	BLX listens on all the IP addresses configured on the Linux host	Sets the NSIP address for BLX in dedicated mode.
`blx-managed-host`	1	Disabled	Configures SSH access to the Linux host through BLX.
`host-ipaddress`	IP address	None	Sets the IP address on which you want SSH access to the Linux host through BLX. Note: You must use this parameter along with the `blx-managed-host` parameter.
`total-hugepage-mem`	Minimum: 1G and Maximum: As available on the Linux host	1G	Configures DPDK Huge page memory for BLX.
`interfaces`	NIC port names as shown on the Linux host CLI	BLX shares the host traffic with all the interfaces	The specified NIC ports of the Linux host are dedicated to BLX.
`default`	IP address	None	Sets the default route for the dedicated interfaces.
`cli-cmds`	NetScaler CLI commands	None	List the NetScaler CLI commands that you want to run when the BLX starts.
`nsdrvd`	1, 2, or 3	Disabled	Configures the `nsdrvd` driver to improve packet processing performance.

Note:

If you want to disable a parameter, comment the parameter with # in the blx.conf file and restart BLX using the systemctl restart blx command. The changes are applied after the BLX reboots.
