5.5.10.2. Prerequisites
User: setup
Commands used in this procedure:
5.5.10.3. Preliminary operations
Connect to the GCap (see Procedure for connecting to the GCap via SSH).
Stop the detection engine (see monitoring-engine).
5.5.10.4. Procedure A: Display the network configuration
In this procedure, only the information on the capture interfaces is detailed.
For information on GPCx network interfaces, refer to the Procedure for managing the network settings of gcp0
and gcp1
interfaces.
Enter the
show network-config configuration
command then validate.The system displays the information of all network interfaces.
(gcap-cli) show network-config configuration
{
...
},
"mon0": {
"description": "default",
"enabled": true,
"filtering_rules": {},
"mtu": 1500
},
"mon1": {
"description": "default",
"enabled": false,
"filtering_rules": {},
"mtu": 1500
},
"mon2": {
"description": "default",
"enabled": false,
"filtering_rules": {},
"mtu": 1500
},
"mon3": {
"description": "default",
"enabled": false,
"filtering_rules": {},
"mtu": 1500
}
}
Note
The mon0
interface is enabled (enabled field: true).
The mon1
to mon3
interfaces are disabled (enabled field: false).
5.5.10.5. Procedure B: display or change the MTU value
To display the current configuration of enabled interfaces:
Enter the following command.
(gcap-cli) show advanced-configuration mtu
Validate.
The system displays the result.
Current Network MTU configuration: - mon1: 1500 - mon2: 1500 - mon3: 1500 - cluster0: 1500 - gcp0: 1500
The values are displayed for all enabled network interfaces.
To change the current configuration of enabled interfaces: e.g. to change the MTU value of the
mon1
interfaceEnter the following command.
(gcap-cli) set advanced-configuration mtu mon1 2000
Validate.
The system displays the result.
Updating Network MTU configuration to: - mon1: 2000
5.5.10.6. Procedure C: display or change the available detection interfaces
To display the information on the detection interfaces:
Enter the following command.
(gcap-cli) show interfaces
Validate.
The system displays the available detection interfaces.
Waiting 10s for interfaces to be up Name State Physical Address Status Speed Type mon0 Enabled xx:xx:xx:xx:xx:xx UP 10Gb 10G Base-SR mon1 Disabled xx:xx:xx:xx:xx:xx UP 1Gb 1G Base-SR mon2 Disabled xx:xx:xx:xx:xx:xx UP 1Gb 1G Base-SR mon3 Disabled xx:xx:xx:xx:xx:xx UP 1Gb 1G Base-SR monvirt Enabled N/A UP N/A Virtual
The information displayed is:
Status: the configured status of the interface among {Enabled|Disabled}
Physical Address: the MAC address of the interface
Speed: the speed of the interface
Type:
if it concerns a virtual interface: Virtual
if it is a physical interface: the type of cable/sfp connected to the physical port
To activate an interface (here mon0 for example):
Enter the following command.
(gcap-cli) set interfaces enable mon0
Validate.
To deactivate an interface (here mon0 for example):
Enter the following command.
(gcap-cli) set interfaces disable mon1
Validate.
To change the interface start-up delay by five seconds for example
Enter the following command.
(gcap-cli) set interfaces delay 5
Validate.
