connection-limit

Use connection-limit to create a connection limit policy and enter its view.

Use undo connection-limit to remove the configuration.

Syntax

connection-limit { ipv6-policy | policy } policy-id

undo connection-limit { ipv6-policy | policy } policy-id

Default

No connection limit policy exists.

network-admin

Parameters

ipv6-policy: Specifies an IPv6 connection limit policy.

policy: Specifies an IPv4 connection limit policy.

policy-id: Specifies the ID of a connection limit policy. An IPv4 or IPv6 connection limit policy has its own number. The value for this argument is 1 to 32.

Examples

# Create IPv4 connection limit policy 1 and enter its view.

<Sysname> system-view

[Sysname] connection-limit policy 1

[Sysname-connlmt-policy-1]

Parameters

global: Displays statistics about IPv6 connections that match connection limit rules globally.

interface interface-type interface-number: Specifies an interface by its type and number.

slot slot-number: Specifies an IRF member device by its member ID. This option is available only when you specify the global keyword or specify a virtual interface, such as a VLAN-interface.

destination destination-ip: Specifies a destination by its IP address.

service-port port-number: Specifies a service port by its port number.

source source-ip: Specifies a source by its IP address.

count: Displays only the number of limit rule-based statistics sets. Detailed information about the specified IPv6 connections is not displayed. If you do not specify this keyword, the command displays detailed information about the specified IPv6 connections that match connection limit rules.

Usage guidelines

The statistics for connections that match connection limit rules include the following information:

·     Connection information, including the source/destination IP address, service port, and transport layer protocol of connections.

·     Matching connection limit rules.

·     Number of current connections.

·     Whether or not new connections can be created.

To further filter the output statistics, specify the following options in the command:

·     source source-ip.

·     destination destination-ip.

·     service-port port-number.

For example, if you specify the source source-ip and destination destination-ip combination, this command displays statistics about IPv6 connections that match connection limit rules by source IP address and destination IP address.

If you specify none of the source source-ip, destination destination-ip, and service-port port-number options, this command displays statistics about all IPv6 connections that match connection limit rules.

limit limit-id acl { acl-number | name acl-name } [ per-destination | per-service | per-source ] * { amount max-amount min-amount | rate rate } * [ description text ]

undo limit limit-id

Default

No connection limit rule exists in the connection limit policy.

Parameters

limit-id: Specifies a connection limit rule by its ID. The value range for this argument is 1 to 256.

acl: Specifies the ACL that matches the user range. Only the user connections that match the ACL are limited.

ipv6: Specifies an IPv6 ACL. If you do not specify this keyword, an IPv4 ACL is used.

acl-number: Specifies an ACL by its number in the range of 2000 to 3999.

name acl-name: Specifies an ACL by its name.

per-destination: Limits connections by destination IP address.

per-service: Limits connections by service depending on transport layer protocol and service port.

per-source: Limits connections by source IP address.

amount: Limits the number of connections.

max-amount: Specifies the upper connection limit in the range of 1 to 4294967294. When user connections in a range or of a type exceed the upper connection limit, new connections cannot be created.

min-amount: Specifies the lower connection limit in the range of 1 to 4294967294. The lower connection limit cannot be greater than the upper connection limit. New connections cannot be created until the connection number goes below the lower connection limit.

rate: Limits the connection establishment rate.

rate: Specifies the maximum number of connections established per second. The value range is 5 to 10000000.

description text: Specifies a description for the connection limit rule, a case-sensitive string of 1 to 127 characters. By default, a connection limit rule does not have a description.

Usage guidelines

Each connection limit policy can define multiple rules. Each rule must specify the used ACL, rule type, and either of upper/lower connection limit and connection establishment rate limit. In one rule, you can specify one or multiple of the keywords per-destination, per-source, and per-service. For example, if the per-destination and per-source combination is specified, connections are limited by the source IP address and destination IP address. Connections with the same source IP address and destination IP address are the same type.

When you configure a connection limit rule, follow these restrictions and guidelines:

·     Different rules in the same connection limit policy must use different ACLs.

·     If you specify none of the per-destination, per-source, and per-service keywords, all connections that match the specified ACL are limited by the specified value.

·     When the connections established on a device are matched against a connection limit policy, the limit rules in the policy are matched in ascending order of rule ID.

·     When the specified ACL changes, the connections that have been established are limited by the new connection limit policy.

Examples

# Configure connection limit rule 1 for IPv4 connection limit policy 1:

1.     Configure ACL 3000.

<Sysname> system-view

[Sysname] acl advanced 3000

[Sysname-acl-ipv4-adv-3000] rule permit ip source 192.168.0.0 0.0.0.255

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

2.     Limit connections that match ACL 3000 by the source and destination IP addresses, with the upper limit 2000, lower limit 1800, and establishment rate 10 per second.
