class

Use class to specify a Wide Area Application Services (WAAS) class for a WAAS policy and enter WAAS policy class view.

Use undo class to remove a WAAS class from a WAAS policy.

Syntax

class class-name [ insert-before existing-class ]

undo class class-name

Default

No WAAS class exists in a WAAS policy.

Views

WAAS policy view

Predefined user roles

network-admin

Parameters

class-name: Specifies a WAAS class by its name, a case-insensitive string of 1 to 63 characters. The specified class must already exist.

insert-before existing-class: Inserts the new class before an existing class in the WAAS policy. If you do not specify this option, the new class is placed at the end of the WAAS policy.

Usage guidelines

A WAAS policy can use system-defined WAAS classes (see Table 7).

As a best practice, configure a WAAS class by modifying a system-defined WAAS class.

You can also use this command to arrange existing WAAS classes in a WAAS policy.

A packet is checked against WAAS classes in the specified order. When a packet matches a class, the action for the class is performed on the packet, and the match process ends.

If you do not configure an action for a WAAS class, the device ignores the WAAS class.

Examples

# Specify the system-defined WAAS class AFS for the WAAS policy waas_global, and enter the view of the WAAS class AFS.

<Sysname> system-view

[Sysname] waas policy waas_global

[Sysname-waaspolicy-waas_global] class AFS

Syntax

match [ match-id ] tcp { any | destination | source } [ ip-address ipv4-address [ mask-length | mask ] | ipv6-address ipv6-address [ prefix-length ] ] [ port port-list ]

undo match match-id

Default

No match criterion exists.

Views

Predefined user roles

network-admin

Parameters

match-id: Specifies the ID of the match criterion, in the range of 1 to 65535. If you specify an unused ID, you can create a new match criterion. If you specify a used ID, you can modify the existing match criterion. If you do not specify an ID, the system automatically assigns the lowest available ID.

tcp: Matches TCP packets.

any: Matches any TCP packets.

destination: Specifies destination elements for matching TCP packets.

source: Specifies source elements for matching TCP packets.

ip-address ipv4-address: Specifies an IPv4 address for matching TCP packets.

mask-length: Specifies the mask length for the IPv4 address, in the range of 0 to 32. The default is 32.

mask: Specifies the mask for the IPv4 address. The default is 255.255.255.255.

ipv6-address ipv6-address: Specifies an IPv6 address for matching TCP packets.

prefix-length: Specifies the prefix length for the IPv6 address, in the range of 0 to 128. The default is 128.

port port-list: Specifies a space-separated list of up to 10 port items for matching TCP packets. Each item specifies a port number or a range of port numbers in the form of port-number1 to port-number2. The value for port-number2 must be greater than or equal to the value for port-number1. The value range for the port-number argument is 1 to 65535. If you do not specify a port list, all port numbers are matched.

Usage guidelines

If you specify the destination or source keyword, you must specify the ip-address (or ipv6-address) option, the port option, or both.

If you specify the any keyword, the ip-address (or ipv6-address) option, and the port option, the ip-address (or ipv6-address) and port options match either source or destination fields of packets.

You cannot configure the same match criteria with different match IDs.

A WAAS class can have a maximum of 65535 match criteria. A packet is checked against match criteria in their order of appearance. The packet belongs to the WAAS class if it matches any one of the match criteria.

A WAAS class without any match criteria is not used to match packets.

Examples

# Create a WAAS class named http_class, and configure the class to match packets with source IP address 192.168.0.1/16 and port number 80 or port number in the range of 8000 to 8080.

Parameters

policy-name: Specifies a WAAS policy by its name, a case-insensitive string of 1 to 63 characters. The specified policy must already exist. If you do not specify a WAAS policy, this command applies the system-defined WAAS policy waas_default.

Usage guidelines

Apply a WAAS policy to an interface that connects to the WAN (not an interface that connects to the LAN). The device optimizes or passes through the traffic entering and leaving the WAN according to the configured policy. If the incoming and outgoing interfaces of the traffic are both connected to the WAN, the traffic is not optimized.

A global logical interface (such as a Layer 3 aggregate interface or VLAN interface) that spans multiple cards or IRF member devices can be used to connect to the WAN. To ensure the traffic optimization effect for such an interface, use the service command to specify one of these cards or IRF member devices to forward traffic for the interface.

Examples

# Apply the WAAS policy global_policy to the interface GigabitEthernet 1/0/1.

waas dre cache aging

Use waas dre cache aging to set the aging time for entries in the data dictionary.

Use undo waas dre cache aging to restore the default.

Syntax

waas dre cache aging minutes

undo waas dre cache aging

Default

Entries in the data dictionary are not aged out, and the newly created entry overwrites the oldest entry if the number of data dictionary entries reaches the limit.

Views

System view

Predefined user roles

network-admin

Parameters

minutes: Specifies the aging time for entries in the data dictionary, in the range of 10 to 60 minutes.

Usage guidelines

The device polls all data dictionary entries and deletes the entries that are not hit within the aging time. If the number of data dictionary entries reaches the limit, the device no longer creates new entries.

The amount of time used by the device to poll all data dictionary entries depends on the number of data dictionary entries on the device.

You must set the same aging time on the local and peer devices.

Examples

# Set the aging time to 10 minutes for entries in the data dictionary.

<Sysname> system-view

[Sysname] waas dre cache aging 10

waas dre offset-step

Use waas dre offset-step to set the DRE match offset step.

Use undo waas dre offset-step to restore the default.

Syntax

waas dre offset-step { general | fast | fastest | normal }

undo waas dre offset-step

Default

The DRE match offset step is normal.

Views

System view

Predefined user roles

network-admin

Parameters

general: Specifies the DRE match offset step as general.

fast: Specifies the DRE match offset step as fast.

fastest: Specifies the DRE match offset step as fastest.

normal: Specifies the DRE match offset step as normal.

Usage guidelines

The following DRE match offset step levels are listed from high to low:

· fastest.

· fast.

· general.

· normal.

The higher the step level, the lower the match precision. As a best practice, use a higher-level offset step on high-speed links to improve match efficiency. Use a lower-level offset step on low-speed links to ensure match precision.

Examples

# Set the DRE match offset step to fast.

<Sysname> system-view

[Sysname] waas dre offset-step fast

waas policy

Use waas policy to create a WAAS policy and enter its view, or enter the view of an existing WAAS policy.

Use undo waas policy to delete a WAAS policy.

Syntax

waas policy policy-name

undo waas policy policy-name

Default

Only the system-defined WAAS policy waas_default exists.

Views

System view

Predefined user roles

network-admin

Parameters

policy-name: Specifies a name for the WAAS policy, a case-insensitive string of 1 to 63 characters.

Usage guidelines

To delete a WAAS policy applied to an interface, first remove the WAAS policy from the interface.

As a best practice, configure a WAAS policy by entering the system-defined WAAS policy view and modifying the system-defined WAAS policy. The system-defined WAAS policy is created by the system when the WAAS process starts for the first time. The system-defined WAAS policy uses all system-defined WAAS classes. Only system-defined WAAS classes FTP-Data and FTPS-Data use source ports as match options. All other system-defined WAAS classes use destination ports as match options.

Usage guidelines

This feature automatically discovers servers that cannot receive TCP packets with options and adds the server IP addresses and port numbers to a blacklist.

During the 3-way handshake, the local device considers the TCP connection attempt failed if either of the following situations occurs:

· The peer device does not respond within the specified time period.

· The peer device closes the TCP connection.

Examples

Predefined user roles

network-admin

Parameters

limit: Specifies the maximum number of concurrent connections, in the range of 1000 to 4294967295.

Usage guidelines

After the maximum number of concurrent connections is reached, WAAS does not optimize traffic for newly established connections. Configure the maximum number of concurrent connections according to your available memory resources, because optimizing TCP flows consumes memory resources.

You must set the same maximum number of concurrent connections on the local and peer devices.

Examples

# Set the maximum number of concurrent connections to 20000.

<Sysname> system-view

[Sysname] waas tfo connect-limit 20000
