object-group

network (IPv4 address object group view)

Use network to configure an IPv4 address object.

Use undo network to delete an IPv4 address object.

Syntax

[ object-id ] network { host { address ip-address | name host-name [ vpn-instance vpn-instance-name ] } | subnet ip-address { mask-length | mask } }

undo network { host { address ip-address | name host-name [ vpn-instance vpn-instance-name ] } | subnet ip-address { mask-length | mask } }

undo object-id

Default

No IPv4 address objects exist.

network-admin

Parameters

object-id: Specifies an object ID in the range of 0 to 4294967294. If you do not specify an object ID, the system automatically assigns the object a multiple of 10 next to the greatest ID being used. For example, if the greatest ID is 22, the system automatically assigns 30.

host: Configures an IPv4 address object with the host address or name.

address ip-address: Specifies an IPv4 host address.

name host-name: Specifies a host name, a case-insensitive string of 1 to 60 characters.

vpn-instance vpn-instance-name: Specifies a VPN instance name, a case-sensitive string of 1 to 31 characters.

subnet ip-address { mask-length | mask }: Configures an IPv4 address object with the subnet address followed by a mask length in the range of 0 to 32 or a mask in dotted decimal notation.

Usage guidelines

This command fails if you use it to configure or change an IPv4 address object to be identical with an existing object.

This command creates an IPv4 address object if the specified object ID does not exist. Otherwise, the command overwrites the configuration of the specified object.

If you configure a subnet with the mask length of 32 or the mask of 255.255.255.255, the system configures the object with a host address.

Examples

# Configure an IPv4 address object with the host address of 192.168.0.1.

<Sysname> system-view

[Sysname] object-group ip address ipgroup

[Sysname-obj-grp-ip-ipgroup] network host address 192.168.0.1

# Configure an IPv4 address object with the host name of pc3.

<Sysname> system-view

[Sysname] object-group ip address ipgroup

[Sysname-obj-grp-ip-ipgroup] network host name pc3

# Configure an IPv4 address object with the host name of pc1 and the VPN instance name of vpn1.

<Sysname> system-view

[Sysname] object-group ip address ipgroup

[Sysname-obj-grp-ip-ipgroup] network host name pc1 vpn-instance vpn1

# Configure an IPv4 address object with the IPv4 address of 192.167.0.0 and mask length of 24.

<Sysname> system-view

[Sysname] object-group ip address ipgroup

[Sysname-obj-grp-ip-ipgroup] network subnet 192.167.0.0 24

# Configure an IPv4 address object with the IPv4 address of 192.166.0.0 and mask of 255.255.0.0.

<Sysname> system-view

[Sysname] object-group ip address ipgroup

[Sysname-obj-grp-ip-ipgroup] network subnet 192.166.0.0 255.255.0.0

object-group

Use object-group to configure an object group and enter its view, or enter the view of an existing object group.

Use undo object-group to delete an object group.

Syntax

object-group ip address object-group-name

undo object-group ip address object-group-name

Default

Default object groups exist.

Views

System view

Predefined user roles

network-admin

Parameters

ip address: Configures an IPv4 address object group.

object-group-name: Specifies an object group name, a case-insensitive string of 1 to 31 characters.

Usage guidelines

The object-group command execution results vary with the specified object group.

·     If the specified group does not exist, the system creates a new object group and enters the object group view.

The undo object-group command execution results vary with the specified object group.

·     If the specified group does not exist, the system executes the command without any system prompt.

·     If the specified object group is being used by an ACL, the command fails.

Default object groups cannot be deleted.

Examples

# Configure an IPv4 address object group named ipgroup.

<Sysname> system-view

[Sysname] object-group ip address ipgroup
