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
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
(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
Service node configuration
Device Modes
application-accelerator
appnav-controller
Examples
The following example shows how to configure a description:
WAE(config)# service-insertion service-node
WAE(config-sn)# description London branch node 1
(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.
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
(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)# GigabitEthernet 1
WAE(config-sn)# portchannel 2
WAE(config-sn)# standby 1
(config-sn) shutdown
To configure the WN shutdown timeout, use the shutdown service node configuration command. To unconfigure the shutdown timeout, use the no form of this command.
shutdown max-wait seconds
no shutdown max-wait
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. |
Defaults
The shutdown waiting time is 120 seconds.
Command Modes
Service node configuration
Device Modes
application-accelerator
appnav-controller
Examples
The following example shows how to configure the shutdown timeout for two minutes:
WAE(config)# service-insertion service-node
WAE(config-sn)# shutdown max-wait 120
