Service Node Configuration Mode Commands


To configure a WAAS Node (WN) that is part of an AppNav Cluster, use the service-insertion service-node global configuration command. To unconfigure settings, use the no form of this command.

service-insertion service-node {authentication sha1 key authkey | description description | enable | node-discovery enable | shutdown max-wait seconds}

no service-insertion service-node {authentication sha1 key authkey | description description | enable | node-discovery enable | shutdown max-wait seconds}

Syntax Description

authentication sha1 key authkey

(Optional) Enables authentication between the WN and other devices in the AppNav Cluster and specifies an authentication key of up to 64 alphanumeric characters. This key must match the key configured in the service context.

description description

(Optional) Specifies a description of the node with up to 200 alphanumeric and space characters.

enable

(Optional) Enables the participation of the node in the AppNav Cluster.

node-discovery enable

(Optional) Specifies service-node discovery parameters and enables service-node discovery.

shutdown max-wait seconds

(Optional) Specifies the number of seconds that the node should wait for all connections to terminate when shutting down. Valid values range from 0-3600 seconds. The default is 120 seconds.


Defaults

There is no authentication key and no description configured. The shutdown waiting time is 120 seconds. The node is disabled.

Command Modes

global configuration

Device Modes

application-accelerator

appnav-controller

Usage Guidelines

Use the service-insertion service-node command to configure a WN that is part of an AppNav Cluster. When used without options, this command initiates the service node configuration mode, which is indicated by a different prompt (config-sn). To return to global configuration mode, enter the exit command.

Each WN (and ANC acting as a WN) in the AppNav Cluster must be configured with WN settings by using the service-insertion service-node command. To begin using the node in the cluster, you must use the enable option.

Examples

The following example shows how to configure and enable a WN:

WAE(config)# service-insertion service-node
WAE(config-sn)# description London branch node 1
WAE(config-sn)# authentication sha1 key myauthkey
WAE(config-sn)# shutdown max-wait 120
WAE(config-sn)# enable

(config-sn) authentication

To configure the WN authentication key, use the authentication service node configuration command. To unconfigure the authentication key, use the no form of this command.

authentication sha1 key authkey

no authentication sha1 key

Syntax Description

sha1 key authkey

Enables authentication between the WN and other devices in the AppNav Cluster and specifies an authentication key of up to 64 alphanumeric characters.


Defaults

No key is defined and authentication is not enabled.

Command Modes

Service node configuration

Device Modes

application-accelerator

appnav-controller

Usage Guidelines

The specified key must match the key configured in the service context.

Examples

The following example shows how to configure an authentication key:

WAE(config)# service-insertion service-node
WAE(config-sn)# authentication sha1 key myauthkey

(config-sn) description

To configure the WN description, use the description service node configuration command. To unconfigure the description, use the no form of this command.

description description

no description

Syntax Description

description

Specifies a description of the node with up to 200 alphanumeric and space characters.


Defaults

No default behavior or values.

Command Modes

(config-sn) enable

To enable the participation of the WN in the AppNav Cluster, use the enable service node configuration command. To disable the node, use the no form of this command.

enable

no enable

Syntax Description

This command has no arguments or keywords.

Defaults

Disabled.

Command Modes

Service node configuration

Device Modes

application-accelerator

appnav-controller

Usage Guidelines

A WN must be enabled before it can actively particpate in an AppNav Cluster and receive traffic for optimization.

Examples

The following example shows how to enable a WN for participation in an AppNav Cluster:

WAE(config)# service-insertion service-node
WAE(config-sn)# enable

(config-sn) description

(config-sn) node-discovery enable

(config-sn) shutdown

(config) service-insertion

show service-insertion

(config-sn) node-discovery enable

To enable the node discovery of the Service Node(SN) in the AppNav Cluster, use the node-discovery enable service node configuration command. To disable the service node, use the no form of this command.

node-discovery enable{bvi bridge_group_number | GigabitEthernet interface_slot | portchannel etherchannel_index | standby standby_index}

no node-discovery enable

Syntax Description

bvi bridge_group_number

Select a bridge virtual interface for node-discovery.

GigabitEthernet interface_slot

Selects a gigabit ethernet interface for node discovery.

portchannel etherchannel_ index

Selects an ethernet channel interface for node discovery.

standby standby_index

Selects a standby group for node discovery.


Defaults

When service node is enabled, node discovery is enabled by default on eth0 interface.

Command Modes

Service node configuration

Device Modes

application-accelerator

appnav-controller

Usage Guidelines

Use the node-discovery enable command to configure the service node in the L2 proximity of any participating AppNav Controller so that it is automatically added to the cluster and can participate in WAN optimization. The node discovery configuration for a Service Node cannot be changed when the SN is enabled. To make changes on the node discovery configuration for a SN, the SN should be first disabled. For e.g. if you want to enable/disable the node discovery or change the node discovery interface, you can do so only when the SN is disabled.

Examples

The following example shows how to enable the node discovery of a SN for participation in an AppNav Cluster:

WAE(config)# service-insertion service-node
WAE(config-sn)# node-discovery enable ?
WAE(config-sn)# bvi 1
WAE(config-sn)# GigabitEthernet 1

WAE(config-sn)# portchannel 2
WAE(config-sn)# standby 1

Syntax Description

max-wait seconds

Specifies the number of seconds that the node should wait for all connections to terminate when shutting down. Valid values range from 0-3600 seconds. The default is 120 seconds.
