Introduction
The basic configuration is the first configuration applied to each WAE, is performed through the Console port using the CLI interface. The base-configuration contains the minimum amount of configuration settings required to bring the WAE up on the network and register it with the CM.
The following settings are configured on each WAE as part of the base-configuration:
Device Naming
Interface Configuration
Default Gateway
Domain Name
Name Servers
Primary Interface
Central Manager Address
WAE Basic Configuration
Device Naming
A structured naming standard for all network devices ensures unique names, as well as aid in the identification of devices by name. Additionally it allows for scripting and management system parsing where / if required.
The syntax for configuring a hostname on the WAAS device is given below.
wae#hostname
Interface Configuration
While it is possible to connect a WAE appliance to the network with only one (1) interface, Cisco Advanced Services recommends using two interfaces (2) as a Best Practice (wherever possible). This will ensure that the WAAS devices are protected against link failures. Two (2) different configurations are supported, as outlined below:
Port-Channel Interface
Standby Interface
The configuration syntax for configuring a Port-Channel is shown below.
primary-interface PortChannel 1
int portChannel 1
ip address
exit
interface GigabitEthernet 1/0
channel-group 1
exit
interface GigabitEthernet 2/0
channel-group 1
exit
The configuration syntax for configuring a Standby Interface is shown below.
primary-interface Standby 1
interface Standby 1
ip address
exit
interface GigabitEthernet 1/0
standby 1 priority 105
exit
interface GigabitEthernet 2/0
standby 1
exit
Note that depending on the device which the WAE is being connected to, it will either need to be configured to hard-set the speed and duplex settings, or otherwise leave it at auto-sense.
If the WAE is being connected to a Gigabit interface, then the interface needs to be left at auto-sense. The following commands needs to be entered when configuring a Gigabit interface:
WAE(config)#interface gigabitEthernet 1/0
WAE(config-if)#ip address
WAE(config-if)#no shutdown
If the WAE device is being connected to a FastEthernet port, the interface needs to be hard-set 100Mbps and Full Duplex mode. The following commands need to be entered for configuring a FastEthernet interface:
WAE(config)#interface FastEthernet 1/0
WAE(config-if)#ip address
WAE(config-if)#full-duplex
WAE(config-if)#speed 100
WAE(config-if)#no shutdown
When connected, it is important to verify the interfaces have negotiated speed and duplex correctly as this severely impacts performance. There should not be any half-duplex links operating in the entire path between Clients and servers.
Default Gateway
The Default Gateway configured on each WAE will depend on the WAE integration model to that site. Sites with only a single router will use the IP address of the WAE VLAN interface on the router as the Default Gateway. Sites with more than one router with HSRP configured for WAE VLAN, will use HSRP VIP IP addresses as the Default Gateway.
WAE(config)#ip default-gateway
Domain Name and Name server
Each WAE device present in the Customer network should be configured with a DNS suffix and one or more DNS servers.
WAE(config)#ip domain-name
WAE(config)#ip name-server
WAE(config)#ip name-server
Central Manager Address
The Central Manager Address configuration is what instructs the WAE how to contact the WAAS Central Manager. Each WAE is manually configured with the address of the Central Manager.
WAE(config)# central-manager address <172.25.44.50>
WAE(config)# cms enable
Configuring Core WAE
To install and configure the WAAS Core WAE device, and register it with the WAAS Central Manager, first power up the designated Core WAE and open a console connection. When a WAAS device boots, you are prompted to run the first-time setup utility (enter basic configuration), which you use to set up the basic network parameters for the device. Configure its network properties and assign this device's primary interface and specify application-accelerator as its device mode.
WAE(config)# primary-interface gigabitEthernet 1/0
WAE(config)# device mode application-accelerator
