You create and configure a loopback interface at the network interface loopback level.
To create an interface, use the following command:
Admin@nodename# create network interface loopback
Parameters:
Parameter |
Description |
---|---|
enabled |
Enable/disable the interface:
|
interface-name |
The interface name. |
description |
Network interface description. |
alias |
The interface's alias. |
ip-addresses |
Assign an IP address to the interface. The IP addresses are specified as [ <ip_address/mask> ], the subnet mask is entered in the decimal format. Important! Make sure to separate the square brackets with spaces on both sides. |
iface-mode |
IP address assignment mode:
Static mode is set automatically when an IP address is assigned to the interface. |
lldp-profile |
Profile to send data using Link Layer Discovery Protocol (LLDP). For more details on configuring profiles, see Configuring LLDP Profiles. |
zone |
Zone to which the interface belongs. |
link-info |
Settings for interface parameters:
To specify them, use the following format: Admin@nodename# create network interface <iface-type> ... link-info [ key/value ] where key is the parameter name. which can include lowercase Latin letters (a-z) and underscore (_), and value is the parameter value. Parameter values can only be integers. For example, use proxy_arp/1 to enable the Proxy ARP mechanism and proxy_arp/0 to disable it. The link-info field is displayed only when adding parameters. Important! You cannot delete the specified parameters. |
netflow-profile |
The Netflow profile to send statistical data to the Netflow collector. For more details on Netflow profile settings, see Configuring Netflow Profiles. |
node-name |
Cluster node where the interface is created. |
mac |
Interface MAC address. |
mtu |
Specify the MTU size. |
dhcp-relay |
Settings for the DHCP relay on the interface. You need to specify the following:
|
To edit an existing interface, use the following command:
Admin@nodename# set network interface loopback <interface-name>
The parameters available for setting are the same as those for creating a loopback interface, except for node-name and interface (you cannot change these parameter values).
To delete a loopback interface or its parameters, use the following command:
Admin@nodename# delete network interface loopback <interface-name>
You can delete the following parameters:
Parameter |
Description |
---|---|
ip-addresses |
Specified IP address. |
dhcp-relay |
DHCP server IP address. |
To display information about all loopback interfaces, use the following command:
Admin@nodename# show network interface loopback
To display information about a single interface, use the following command:
Admin@nodename# show network interface loopback <interface-name>
