Strong Password Enforcement
Consider the following guidelines for administrator account passwords for different Cisco WAAS versions:
For Cisco WAAS Version 6.4.3d and earlier: Changing the password of the administrator account is recommended but optional after your initial login.
For Cisco WAAS Version 6.4.3e and later: Changing the password of the administrator account to a strong password is required after your initial login, regardless of device mode (Application Accelerator, Appnav or Central Manager).
The Cisco WAAS administrator account username is admin and the password is initially set to default.
Note For how to change the Cisco WAAS administrator account username and password, see the chapter “Creating and Managing Administrator User Accounts and Groups” in the Cisco Wide Area Application Services Configuration Guide.
Note Strong password enforcement is applicable only to the Administrator account with the username admin.
Consider the following guidelines for strong password enforcement:
- After the Cisco WAAS administrator account password has been changed, it is pushed to the NFVIS admin user account as well, so that the WAAS and NFVIS admin users have the same password.
Note For the strong password enforcement to take effect for vWAAS on the Cisco ENCS 5400-W series or the Cisco CSP 5000-W series, you must do a fresh installation of Cisco WAAS 6.4.3e.
- At the first login after the fresh deployment of Cisco WAAS Version 6.4.3e or later, the default username and password are shown in the following list.
You must change the username and password using the following parameters:
– At least one lowercase character (a-z)
– At least one uppercase character (A-Z)
– At least one number (0-9)
– At least one special character
– A password length of 8 to 31 characters
- Before the device is registered to the Cisco WAAS Central Manager, the WAAS and NFVIS admin user will have the same password. After the device is registered to the Cisco WAAS Central Manager, the WAAS and NFVIS admin user will have the same password as the WAAS admin user.
- Changing the WAAS admin user password will also change the NFVIS admin user.
- If you run the restore factory-default preserve basic-config command or run the restore factory-default command, the WAAS admin user password is set to default, and you will be prompted again to change it to a strong password.
Shared LOM Support
Cisco vWAAS running on ENCS 5400-W Series appliances with WAAS version 6.4.3e and later provides Shared LAN on Motherboard (Shared LOM) support.
The Shared LOM feature helps to re-use existing on-board Ethernet LAN interfaces on Cisco ENCS 5400-W series appliances by providing IP connectivity to Cisco Integrated Management Controller (CIMC) for remote management and health monitoring though SNMP and Syslog, while the same interfaces configured for traffic optimization
Note Shared LOM does not work when a Port-channel interface is configured on Cisco vWAAS running on ENCS 5400-W Series appliances
Using the CIMC CLI to Enable Shared LOM Support
Consider the following guidelines for enabling Shared LOM support:
- Verify that the IP address used for the CIMC management and on-board interfaces belongs to the same VLAN or subnet.
- The Enable/Disable function of Shared LOM configuration should be executed from the CIMC Serial Console interface.
- The CIMC console supports a speed of 9600 only.
The following example configuration shows the steps to enable Shared LOM on Gig 0/1 interface.
ENCS 5000-W# scope cimc/network
ENCS 5000-W /cimc/network # set mode shared_lom
ENCS 5000-W /cimc/network *# set interface value ge0/0 | ge0/1
ENCS 5000-W /cimc/network *# set interface ge0/1
ENCS 5000-W /cimc/network *# commit
Changes to the network settings are applied immediately.
You may lose connectivity to the CIMC and may have to log in again:
ENCS 5000-W /cimc/network #
Using the CIMC CLI to Disable Shared LOM Support
The following example configuration shows the steps to disable Shared LOM:
ENCS 5000-W# scope cimc/network
ENCS 5000-W /cimc/network # set mode dedicated
ENCS 5000-W /cimc/network *# commit
Changes to the network settings are applied immediately.
You may lose connectivity to the CIMC and may have to log in again.

Step 5 Click Create Virtual Drive.
Migrating Equipment from RAID-1 and Two SSDs to No RAID and One SSD
Note The RAID-1 option is available for vWAAS for WAAS Version 6.4.1a and later.
Before You Begin
- You must wait for the disk to be completely shut down before you physically remove the disk from the Cisco WAE device. After the RAID removal process is complete, WAAS generates a disk failure alarm and trap. In addition, a syslog error message is displayed.
- If the removal event occurs while the RAID array is in the rebuild process, the RAID removal process may take up to 1 minute to complete. The duration of this process depends on the size of the disk.
If you administratively shut down the disk during the RAID rebuild process, a RAID rebuild abort alarm is generated instead.
To remove a RAID-1 disk, follow these steps:
Step 1 To manually shut down the disk, run the disk disk-name diskxx shutdown global configuration command:
WAE(config)# disk disk-name diskxx shutdown
Step 2 Wait for the disk to be completely shut down before you physically remove the disk from the Cisco WAE device.
Step 3 After the RAID removal process is complete, Cisco WAAS generates a disk failure alarm and trap. In addition, a syslog error message is displayed.
Note We recommend that you disable the disk error-handling reload option if it is enabled because it is not necessary to power down the system to remove a disk.
Fail-to-Wire on vWAAS on ENCS 5400-W
This section contains the following topics:
About Fail-to-Wire on Cisco vWAAS on Cisco ENCS 5400-W Series
Fail-to-Wire (FTW) is a physical layer (Layer 1) bypass that allows interface port pairs to go into bypass mode: so that the hardware forwards packets between these port pairs without software intervention. FTW provides network connectivity when there are software or hardware failures.
The following are the operating guidelines for FTW on Cisco vWAAS on Cisco ENCS 5400-W:
- FTW is available for Cisco vWAAS in Cisco WAAS Version 6.4.3 and later.
- Hardware bypass is supported for a fixed set of ports. For example, you can pair Port 1 with Port 2, or Port 3 with Port 4, but you cannot pair Port 1 with Port 4.
- Configuring a standby and port channel in an on-board interface is supported; configuring standby over port channel in an on-board interface is not supported.
- Configuring a standby, port channel, and standby over port channel in an FTW interface is supported.
Fail-to-Wire Traffic Interception Modes
FTW uses two traffic interception modes: inline interception and WCCP.
- Inline interception uses the following operating modes:
– Interception Mode: The NIM ports are in interception mode. Two inline groups are created for the four-port NIM card in Cisco vWAAS. The NIM card ports will use fail-to-wire after a failover timeout.
– Bypass Mode: You can shut down the inline group, putting the corresponding pair of ports in bypass mode. In bypass mode, traffic coming into Port 0 is redirected to Port 1, and traffic coming into Port 1 is redirected to Port 0.
– Bypass All Mode: If the system reloads or if the software experiences an unexpected event, all the inline groups can be put in bypass mode; no Ethernet connection can be established between the devices.
- WCCP traffic interception mode:
– Standalone Mode: Each port in the NIM can be used separately. Cisco WAAS can use this mode to enable WCCP interception. The ports of the NIM card do not use fail-to-wire in this mode, and the watchdog timer remains disabled.
Fail-to-Wire Failure Handling
Here is how FTW handles the following system failure scenarios:
- Disk issue: NFVIS detects the disk issue and puts the NIM into bypass mode.
- NFVIS unexpected event: FTW detects that the Cisco vWAAS keepalive messages have stopped, and FTW puts the NIM to pass-through FTW.
- WAAS reload: The Cisco vWAAS puts the FTW card into FTW mode immediately.
- WAASnet restarts or experiences an unexpected event: The FTW NIM card on the vWAAS goes into FTW mode immediately. After the WAASnet datapath is restored, the vWAAS returns the FTW ports to inline mode.

Creating, Removing, and Showing Port Channel Interfaces
The following example shows how to create a port channel with the interface portchannel global configuration command:
vWAAS(config)#interface portchannel 1
vWAAS(config-if)#ip address 10.10.10.10 255.0.0.0
The following example shows how to remove a port channel with the no interface portchannel global configuration command:
vWAAS(config)#interface portchannel 1
vWAAS(config-if)#ip address 10.10.10.10 255.0.0.0
vWAAS(config-if)#no interface portchannel 1
Note The interface port channel and no interface port channel global configuration commands will be saved across reloads if you run the copy running-config startup-config command or the write-mem command.
The following example shows a show running config command for a port channel interface:
ip address 10.10.10.10 255.0.0.0
Creating, Removing, and Showing Standby Interfaces
The following example shows how to create a standby interface with the interface standby global configuration command:
ENCS-APPLIANCE(config)#interface standby 1
ENCS-APPLIANCE(config-if)#ip address 10.10.10.10 255.0.0.0
ENCS-APPLIANCE(config-if)#exit
The following example shows how to remove a standby interface with the no interface portchannel global configuration command:
ENCS-APPLIANCE(config)#interface standby 1
ENCS-APPLIANCE(config-if)#ip address 10.10.10.10 255.0.0.0
ENCS-APPLIANCE(config-if)#exit
ENCS-APPLIANCE(config-if)#no interface standby 1
Note The interface standby and no interface standby global configuration commands are saved across reloads if you run the copy running-config startup-config command or the write-mem command.
The following example shows a show running config command for a standby interface:
ip address <addr> <netmask>

Fail-to-Wire Upgrade and Downgrade Guidelines
Consider the following for upgrading or downgrading a Cisco WAAS device with FTW:
- FTW is not supported for Cisco vWAAS in Cisco WAAS versions earlier than WAAS 6.4.3.
- In a mixed version Cisco WAAS network with FTW, the Cisco WAAS Central Manager must be running Cisco WAAS Version 6.4.3.
Upgrade and Downgrade Guidelines for Cisco vWAAS on Cisco ENCS 5400-W
Consider the following for upgrading or downgrading a Cisco vWAAS device on Cisco ENCS 5400-W:
- You can use the Cisco WAAS Central Manager or the CLI to upgrade a Cisco vWAAS on a Cisco ENCS 5400-W device to the following Cisco WAAS and Cisco NFVIS versions:
– Cisco WAAS Version 6.4.3a and Cisco NFVIS 3.10.1
– Cisco WAAS Version 6.4.3 and Cisco NFVIS 3.9.1
– Cisco WAAS Version 6.4.1x and Cisco NFVIS 3.71
Note If you are running nfvis-371-waas-641a or nfvis-371-waas-641b on a Cisco ENCS 5400-W device, before upgrading Cisco NFVIS, upgrade to Cisco WAAS Version 6.4.3.
- You can use the Cisco WAAS Central Manager to upgrade from the device level and the device group level. To use the Cisco WAAS Central Manager to upgrade a Cisco vWAAS on a Cisco ENCS 5400-W device:
1. Use Telnet to reach the Cisco vWAAS device.
2. Update the Cisco WAAS Central Manager’s IP address.
3. Log in to the Cisco WAAS Central Manager.
- The Cisco WAAS Central Manager supports downgrade of all applicable device types in a device group.
For example, if you are downgrading a device group that has a physical Cisco WAE, a virtual Cisco WAE, and a Cisco ENCS 5400-W platform to a version earlier than Cisco WAAS Version 6.4.1, the Cisco WAAS Central Manager initiates the downgrade process only for the physical and virtual Cisco WAEs, but not for the Cisco ENCS 5400-W platform.
