Configuring CoreXL on a VSX Gateway (g_cpconfig)
Use g_cpconfig to configure CoreXL on the VSX Gateway (VS0). The number of instances for the VSX Gateway is limited to the physical number of CPU cores on the 61000/41000 Security System.
|
Note - If you run this command in a Virtual System, the output applies to VS0.

Syntax
> g_cpconfig corexl stat
> g_cpconfig corexl enable <n> [-6 <k>]
> g_cpconfig corexl disable
> g_cpconfig corexl instances <n> [-6 <k>]
> g_cpconfig corexl show instances
> g_cpconfig corexl show stat
Parameter
|
Description
|
stat
|
Show current status and number of instances on all SGMs.
|
enable <n> [-6 <k>]
|
Enable CoreXL
<n> - Number of IPv4 Firewall instances
-6 <k> - Number of IPv6 Firewall instances.
Valid values: 2 - 32
Default - 16
|
disable
|
Disable CoreXL.
|
instances <n> [-6 <k>]
|
Change the number instances
<n> - Number of IPv4 Firewall instances
-6 <k> - Number of IPv6 Firewall instances
Valid values: 2 - 32
Default - 16
|
show instances
|
Show the number of instances on each blade
|
show stat
|
Show the status on each blade
|
Example - Enabling Cores
> g_cpconfig corexl enable 8 -6 8
-*- 5 blades: 1_01 1_02 2_01 2_02 2_04 -*-
rx_num for ixgbe interfaces was set to: 16
CoreXL was successfully enabled with 8 IPv4 and 8 IPv6 firewall instances.
Important: This change will take effect after rebooting all blades.
Example - Showing CoreXL status for each SGM
> g_cpconfig corexl show stat
blade 1_01 corexl is enabled
blade 1_02 corexl is enabled
blade 1_03 corexl is enabled
CoreXL configuration on a VSX system
When you change the number of CoreXL instances in a Security Gateway environment, all CPUs not assigned to CoreXL are assigned to Performance Pack. When you change the number of CoreXL instances in a VSX Gateway environment, you only change the number of user-mode threads. This has no effect on Performance Pack affinity. The number of CPUs assigned to Performance Pack does not change.
This example shows a system with 12 CPUs and 3 Virtual Systems where:
- Each Virtual Systems has 1 CoreXL instance.
- CPUs 0-7 are assigned to Firewall packet inspection.
- CPUs 8-11 are assigned to Performance Pack.
> g_cpconfig corexl instances 3
- The number of CoreXL instances (user-mode threads) changes from 1 to 3. Each Virtual System still has one CoreXL instance.
- CPUs 0-7 are still assigned to Firewall packet inspection.
- CPUs 8-11 are still assigned to Performance Pack.
