Cisco vWAAS on Cisco ENCS 5400-W Series

This chapter describes Cisco vWAAS on the Cisco Enterprise Network Compute System 5400-W Series (Cisco ENCS 5400-W Series) appliance, and contains the following sections:

About the Cisco ENCS 5400-W Series

The Cisco Enterprise Network Compute Series (Cisco ENCS) is used to host the Cisco Enterprise Network Functions Virtualization (Cisco Enterprise NFV) solution. Cisco ENCS is also used to deploy the Cisco NFV Infrastructure Software (Cisco NFVIS), and Cisco and third-party VNFs on Cisco Enterprise NFV. For more information on Cisco NFVIS, see the chapter "Cisco vWAAS with Cisco Enterprise NFVIS."

The following table describes how the Cisco ENCS 5400 Series and the Cisco ENCS 5400-W Series (used with vWAAS) are used with Cisco Enterprise NFV. For more information, see the Cisco 5400 Enterprise Network Compute System Data Sheet.

This section contains the following topics:


Note

For further information on RAID and the Cisco ENCS 5400-W Series, see the Cisco 5400 Enterprise Network Compute System Hardware Installation Guide.

Migrating Equipment from No RAID and One SSD to RAID-1 and Two SSDs

Before you begin


Note

The RAID-1 option is available for Cisco vWAAS in Cisco WAAS Version 6.4.1a and later.

Consider the following guidelines for mixing drive types in the RAID group:

  • SAS + HDD + SATA HDD: Allowed.

  • SAS + SSD + SATA SSD: Allowed.

  • HDD + SSD: Not allowed.

Consider these best practices for mixing drive types in the RAID group:

  • Use either all SAS or all SATA drives in a RAID group.

  • Use the same capacity for each drive in the RAID group.

  • Never mix HDDs and SSDs in the same RAID group.

Before creating the virtual disk, both drives must be in Unconfigured Good state. If a drive is in other status, use the CIMC Web GUI or Cisco WAAS CLI and do the following:

  • If disk is in JBOD state:

    1. Click the Storage tab > Physical Drive Info tab.

    2. In the Actions area, choose Set State as Unconfigured Good.

    3. Confirm that the disk is in Unconfigured Good state.

  • If disk is in Foreign Config state:

    1. Click the Storage tab > Controller Info tab.

    2. In the Actions area, choose Clear Foreign Config.

    3. In the Actions area, choose Unconfigured Good.

    4. Confirm that the disk is in Unconfigured Good state.

Procedure

Step 1

Log in to the CIMC console.
Step 2

In the CIMC console left pane, click the Storage tab.

Step 3

In the CIMC console middle pane, click the Controller Info tab.

Step 4

In the Action area, click Create Virtual Drive from Unused Physical Drives.

The Create Virtual Drive from Unused Physical Drives Wait dialog box is displayed.

  1. At the RAID Level drop-down box, choose 1.

  2. In the Create Drive Groups area, select physical drives for your system from the Physical Drives pane and click >> to add these to the Drive Groups pane.

  3. In the Virtual Drive Properties area:

    The Virtual Drive Name field displays the automatically assigned name.

    The value for the Size drop-down list automatically filled.

    2. From the Write Policy drop-down list, choose the Write policy (default is Write Through).

    3. From the Access Policy drop-down list, choose the Access policy (default is Read Write).

    4. From the Read Policy drop-down list, choose the Read policy (default is No Read Ahead).

    5. From the Cache Policy drop-down list, choose the Cache policy (default is Direct IO).

    6. From the Disk Cache Policy drop-down list, choose the Disk Cache policy (default is Unchanged).

Step 5

Click Create Virtual Drive.

Migrating Equipment from RAID-1 and Two SSDs to No RAID and One SSD

Before you begin


Note

Online Insertion Removal (OIR) is not supported on ENCS 5400-W appliances. We recommend that you do not remove or replace the external SSD drives while the ENCS 5400-W appliance is up and running.

  • 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, Cisco 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 cancel alarm is generated instead.

Procedure

Step 1

To manually shut down the disk, run the disk disk-name diskxx shutdown global configuration command: 

WAE# configure
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 Cisco vWAAS on ENCS 5400-W Series

This section contains the following topics:

About Fail-to-Wire on Cisco vWAAS on 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 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 for FTW 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 for FTW uses the following operating 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

The following list shows how FTW handles different 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.

CLI Commands for Port Channel and Standby Interfaces

This section contains the following topics:

Show Commands Used with Port Channel and Standby Interfaces

The following table highlights the show commands used with port channel and standby interfaces.

Table 8. show Commands Used with Port Channel and Standby Interfaces

show Command

Description

show statistics f2w

Displays InlineGroup status, including the amount of time, in seconds, since the last keepalive was received, and how many bypass alarms have been received or cleared.

show interface InlineGroup

Displays InlineGroup connection statistics and InlineGroup status, as well as the failover timeout frequency.

show interface InlinePort LAN

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# configure
vWAAS(config)# interface portchannel 1
vWAAS(config-if)# ip address 10.10.10.10 255.0.0.0
vWAAS(config-if)# exit

The following example shows how to remove a port channel with the no interface portchannel global configuration command: 

vWAAS# configure
vWAAS(config)# interface portchannel 1
vWAAS(config-if)# ip address 10.10.10.10 255.0.0.0
vWAAS(config-if)# exit
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 run the write-mem command.

The following example shows a show running config command for a port channel interface:

interface PortChannel 1
ip address 10.10.10.10 255.0.0.0
exit
!
interface Virtual 1/0
channel-group 1
exit
interface Virtual 2/0
channel-group 1
exit

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# configure
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 standby global configuration command: 

ENCS-APPLIANCE# configure
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 run the write-mem command.

The following example shows a show running config command for a standby interface: 

interface Standby 1
 ip address <addr> <netmask>
 exit
!
interface Virtual 1/0
 standby 1 primary
 exit
interface Virtual 2/0
 standby 1
 exit

Fail-to-Wire Upgrade and Downgrade Guidelines

Consider the following guidelines 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 or later.

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 Cisco WAAS CLI to upgrade a Cisco vWAAS on a Cisco ENCS 5400-W device to Cisco WAAS and Cisco NFVIS versions shown in the following table:

    Table 10. Cisco WAAS and NFVIS Versions for Cisco ENCS 5400-W

    Cisco WAAS Version

    Supported Cisco NFVIS Version

    6.4.5a

    4.12

    6.4.5

    3.11.1

    6.4.3e

    4.12

    6.4.3d

    3.11.1

    6.4.3c

    3.10.1

    6.4.3b

    3.10.1

    6.4.3a

    3.10.1

    6.4.3

    3.9.1

    6.4.1x

    3.7.1

    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 Cisco WAAS 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.

  • For upgrade and downgrade guidelines for Cisco vWAAS with Cisco NFVIS, see the chapter "Cisco vWAAS with Cisco Enterprise NFVIS."
