Parameters

name zone-name: Specifies the security zone name, a case-insensitive string of 1 to 31 characters. If you do not specify this option, the command displays all security zones, including system-defined and user-defined security zones.

Usage guidelines

When displaying all security zones, the command uses the following order:

1.     System-defined security zones.

2.     User-defined security zones in alphabetical order of security zone names.

Examples

# Display information about security zone myZone.

<Sysname> display security-zone name myZone

Name: myZone

Members:

  Service path 2 reversed

  GigabitEthernet1/0/1

  GigabitEthernet1/0/2 in VLAN 3

  VLAN 150-200

  192.168.1.0 255.255.255.0

  192.168.0.0 255.255.0.0 vpn-instance abc

  1001:1002::0 32

Table 1 Command output

Field	Description
Name	Security zone name.
Members	Members in the security zone: ·     Type and number of a Layer 3 interface. ·     Type and number of a Layer 2 Ethernet interface, and IDs of the VLANs to which the interface belongs. ·     None. If a security zone does not have members, this field displays None.

 

display zone-pair security

Use display zone-pair security to display all zone pairs.

Syntax

import interface

Use import interface to add Layer 3 interfaces to a security zone, including Layer 3 Ethernet interfaces, Layer 3 Ethernet subinterfaces, and other types of Layer 3 logical interfaces.

Use undo import interface to remove Layer 3 interfaces from a security zone.

Syntax

import interface layer3-interface-type layer3-interface-number

undo import interface layer3-interface-type layer3-interface-number

Default

A security zone does not have Layer 3 interface members.

Parameters

interface layer3-interface-type layer3-interface-number: Specifies a Layer 3 interface by its type and number.

Usage guidelines

You cannot add a member to the system-defined security zone Local. You can add members to the other system-defined security zones.

To add multiple Layer 3 interfaces to a security zone, execute this command multiple times.

A Layer 3 interface can belong to only one security zone. To move a Layer 3 interface from one security zone to another security zone, perform the following tasks:

·     Use the undo import interface command to remove the interface from the current security zone.

·     Use the import interface command to add the interface to the new security zone.

Examples

# Add Layer 3 Ethernet interface GigabitEthernet 1/0/1 to security zone Trust.

<Sysname> system-view

[Sysname] security-zone name trust

[Sysname-security-zone-Trust] import interface gigabitethernet 1/0/1

security-zone

Use security-zone to create a security zone and enter its view, or enter the view of an existing security zone.

Use undo security-zone to delete a security zone.

Syntax

security-zone name zone-name

undo security-zone name zone-name

Default

No security zones exist.

Views

Predefined user roles

network-admin

Parameters

name zone-name: Specifies the security zone name, a case-insensitive string of 1 to 31 characters. It cannot be any. To include a backward slash (\) or quotation mark (") in the security zone name, you must use the escape character (\).

Usage guidelines

The device provides the following system-defined security zones: Local, Trust, DMZ, Management, and Untrust. The system creates these security zones automatically when one of following events occurs:

·     The first command for creating a security zone is executed.

·     The first command related to creating an interzone policy is executed.

System-defined security zones cannot be deleted.

You can use this command multiple times to create multiple security zones.

Deleting a security zone also deletes the following items:

·     All zone pairs that use the security zone as the source or destination security zone.

·     All interzone policy applications on the zone pairs.

Examples

# Create a security zone named zonetest and enter security zone view.

<Sysname> system-view

[Sysname] security-zone name zonetest

[Sysname-security-zone-zonetest]

security-zone intra-zone default permit

Use security-zone intra-zone default permit to set the default action to permit for packets exchanged between interfaces in the same security zone.

Use undo security-zone intra-zone default permit to restore the default.

Syntax

security-zone intra-zone default permit

undo security-zone intra-zone default permit

Default

The default action is deny for packets exchanged between interfaces in the same security zone.

Views

System view

Predefined user roles

network-admin

Usage guidelines

The system uses the default action for packets that are exchanged between interfaces in the same security zone in the following situations:

·     A zone pair from the security zone to the security zone itself is not configured.

·     A zone pair from the security zone to the security zone itself is configured, but no interzone policy is applied to the zone pair.

Examples

# Set the default action to permit for packets exchanged between interfaces in the same security zone.

<Sysname> system-view

[Sysname] security-zone intra-zone default permit

zone-pair security

Use zone-pair security to create a zone pair and enter its view, or enter the view of an existing zone pair.

Use undo zone-pair security to delete a zone pair.

Syntax

zone-pair security source { source-zone-name | any } destination { destination-zone-name | any }

undo zone-pair security source { source-zone-name | any } destination { destination-zone-name | any }

Default

No zone pair exists.

Views

Predefined user roles

network-admin

Parameters

source source-zone-name: Specifies the name of the source security zone, a case-insensitive string of 1 to 31 characters. This security zone must already exist.

destination destination-zone-name: Specifies the name of the destination security zone, a case-insensitive string of 1 to 31 characters. This security zone must already exist.

any: Specifies any security zone.

Usage guidelines

A zone pair has a source security zone and a destination security zone. The device examines received first data packets and uses zone pairs to identify data flows. You can apply interzone policies to zone pairs so the device processes data flows based on interzone policies.

You can use the zone-pair security source any destination any command to define the any-to-any zone pair. This zone pair matches all packets from one security zone to another security zone.

A zone pair between specific security zones has a higher priority than the any-to-any zone pair.

A packet between the Management and Local zones matches only zone pairs of the two zones. It does not match the any-to-any zone pair.

Deleting a zone pair deletes all interzone policy applications on the zone pair.

Examples

# Create a zone pair with the source security zone Trust and destination zone Untrust.

<Sysname> system-view

[Sysname] zone-pair security source trust destination untrust

[Sysname-zone-pair-security-Trust-Untrust]

zone-pair vsip-filter enable

Use zone-pair vsip-filter enable to enable filtering based on virtual service IP address for zone pairs.

Use undo zone-pair vsip-filter enable to restore the default.

Syntax

zone-pair vsip-filter enable

undo zone-pair vsip-filter enable

Default

Filtering based on virtual service IP address is disabled for zone pairs.

Views

System view

Predefined user roles

network-admin

Usage guidelines

In scenarios where server load balancing is deployed, configure this command to enable the device to filter packets from external networks to internal servers by virtual service IP address. By default, filtering based on virtual service IP address is disabled. Before matching each of the packets against ACLs, the device translates the destination IP address (the virtual service IP address) to the real server IP address. For more information about packet filtering, see ACL configuration in ACL and QoS Configuration Guide.

Examples

# Configure an IPv4 advanced ACL to permit packets destined for virtual server IP address 10.10.10.10. Configure a zone pair from Untrust to DMZ, apply the ACL to the zone pair, and enable filtering based on virtual service IP address.

<Sysname> system-view

[Sysname] acl advanced 3000

[Sysname-acl-ipv4-adv-3000] rule permit ip source any destination 10.10.10.10 0

[Sysname-acl-ipv4-adv-3000] quit

[Sysname] zone-pair security source untrust destination dmz

[Sysname-zone-pair-security-Untrust-DMZ] packet-filter 3000
