Multi-Queue Administration
There are two main roles for CPU cores applicable to SecureXL and CoreXL:
For best performance, the same CPU core should not work in both roles - as CoreXL SND and as CoreXL FW.
Multi-Queue Configuration
Important - See MBS-7978 in sk162552.
Description
The mq_mng utility shows and configures the Multi-Queue on the supported interfaces.
Important - When a new Multi-Queue configuration is applied, the interface is reset. As a result, there is a momentary loss of packets.
Syntax
You must run these commands in the Expert mode.
- To show the existing Multi-Queue configuration:
g_all mq_mng {-o | --show}
[-a]
[{-i | --interface} <Name of Interface 1> <Name of Interface 2> ... <Name of Interface N>]
[-v]
[-vv]
|
- To configure the Multi-Queue:
g_all mq_mng {-s | --set_mode} {auto | manual | off}
[{-i | --interface} <Name of Interface 1> [<Name of Interface 2> ... <Name of Interface N>]]
[{-c | --core} <CPU core 1> <CPU core 2> ...<CPU core N> ... <CPU core X>-<CPU core Y>]
|
- To reconfigure the IRQ affinity of the queues:
g_all mq_mng {-r | --reconf}
|
- To pull the Multi-Queue configuration from the SMO:
g_all mq_mng {-p | --pull}
|
Parameters
Parameter
|
Description
|
-o
--show
|
Shows Multi-Queue status for supported interfaces.
|
-a
|
Shows Multi-Queue status for all interfaces.
|
-i
--interface
|
Applies the command only to the specified interfaces.
With this parameter, you must specify at least one interface name.
Write the names of the interfaces one after another, separated by spaces (for example: -i eth1 eth2).
|
-v
--verbosity
|
Shows verbose output.
|
-vv
|
Shows more verbose output.
|
-s
--set_mode
|
Configures the Multi-Queue mode:
auto - Automatic settings. Multi-Queue is automatically configured using the maximum number of SNDs. Interface queues and IRQ affinity are configured accordingly.manual - Manual settings. The user decides which CPU cores are used for Multi-Queue. Interface queues and IRQ affinity are configured accordingly.off - Multi-Queue is disabled.
|
-c
--core
|
Configures the IRQ affinity to the specified CPU cores.
With this parameter, you must specify at least twp CPU core numbers.
For specific single CPU core numbers, write their numbers one after another, separated by spaces (for example: -c 1 2 5 6).
For a range of CPU core numbers, write their numbers separated by a hyphen (for example: -c 1-3).
|
-r
--reconf
|
Applies the current Multi-Queue configuration again.
|
-p
--pull
|
Pulls the Multi-Queue configuration from the Security Group member, which is the current SMO.

Example 3 - Show the existing Multi-Queue configuration for the interface eth2
# g_all mq_mng --show -v -i eth2

Example 4 - Configure automatic Multi-Queue mode on all interfaces
# g_all mq_mng --set-mode auto
|
Example 5 - Configure manual Multi-Queue mode on interfaces eth1 and eth2 on CPU cores 0, 1, 2, 4, 5, and 6
# g_all mq_mng -s manual -i eth1 eth2 -c 0-2 4-6
