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 11).

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

Parameters

ratio: Specifies the FEC average ratio in the range of 1 to 50, in percentage.

Usage guidelines

The FEC average ratio determines the number of redundant packets generated for a group of original packets. The greater the FEC average ratio, the more the redundant packets generated. FEC average ratio must be greater than the actual packet loss ratio.

Number of redundant packets = Round up (number of original packets x (FEC average ratio/(1–FEC average ratio))

Examples

# Set the FEC average ratio to 30%.

Parameters

block-size: Specifies the maximum number of original packets that can be encoded at a time, in the range of 1 to 150

Usage guidelines

In addition to the block size, the encoding timeout time affects the number of original packets that can be encoded at a time. If the maximum number of encoded packets is reached before the encoding timeout time expires, that number applies. If the encoding timeout time expires before the maximum number is reached, the number of actually encoded packets applies. If the block size is too small, the number of generated redundant packets is small. If the block size is too large, the decoder side will take a long time to recover lost packets. You can set an appropriate block size according to your network bandwidth.

Examples

# Set the maximum number of original packets that can be encoded at a time to 20.

milliseconds: Specifies the decoding timeout time in the range of 30 to 1000 milliseconds.

Usage guidelines

When the total number of cached original packets and redundant packets reaches or exceeds the set number of original packets before the decoding timeout time expires, the decoder performs the following operations:

1. Decodes the cached packets.

2. Recovers lost packets.

3. Sends original packets and recovered packets, and drops redundant packets.

Otherwise, the decoder sends cached original packets and drops cached redundant packets without decoding any packets.

Examples

# Set the decoding timeout time to 500 milliseconds.

Parameters

milliseconds: Specifies the encoding timeout time in the range of 30 to 1000 milliseconds.

Usage guidelines

In addition to the encoding timeout time, the block size affects the number of original packets that can be encoded at a time. If the maximum number of encoded packets is reached before the encoding timeout time expires, that number applies. If the encoding timeout time expires before the maximum number is reached, the number of actually encoded packets applies.

Examples

# Set the encoding timeout time to 60 milliseconds.

Parameters

adaptive-fec: Specifies adaptive FEC (A-FEC).

determined-fec: Specifies determined FEC (D-FEC).

Usage guidelines

If the FEC average ratio is set to a greater value, more bandwidth will be consumed. If the FEC average ratio is set to a small value, lost packets cannot be recovered. A-FEC adjusts the FEC average ratio based on the calculated real-time packet loss ratio. The adjusted FEC average ratio will not be greater than the set FEC average ratio. D-FEC always uses the set FEC average ratio.

Examples

# Set the FEC type to A-FEC.

network-admin

Parameters

seconds: Specifies the aging time in the range of 0 to 60 seconds.

Usage guidelines

If the encoder receives sampled packets within the aging time, it adjusts the FEC average ratio based on the real-time packet loss ratio. If the encoder does not receive sampled packets within the aging time, it deletes the local decoder information and uses the set FEC average ratio.

Examples

# Set the aging time for A-FEC decoder information to 5 seconds.

· object-group ipv6-object-group-name: Specifies an IPv6 address object group by its name, a case-insensitive string of 1 to 63 characters.

port { port-list | object-group port-object-group-name }: Specifies port numbers for matching TCP packets.

· port port-list: Specifies a space-separated list of up to 10 port items. 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.

· object-group port-object-group-name: Specifies a port object group by its name, a case-insensitive string of 1 to 63 characters.

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.

Parameters

class-name: Specifies an RTP 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 packet is checked against RTP WAAS classes in the order they are specified. 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 RTP WAAS class, the device ignores the WAAS class.

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

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.

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.

Predefined user roles

network-admin

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

# Enable the TFO blacklist autodiscovery feature.

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
