Fixes and enhancements in this release

This release includes the following fixes and enhancements.

Fixes

This release includes the following fixes.

Configuring the WANJet appliance from the shell (CR60652)
When using the restricted shell to configure the WANJet appliance, you can now use backspace characters to correct typing errors.

TCP performance (CR61415)
We have improved TCP performance between WANJet appliances to resolve a problem with file transfer speed and zero window sizes.

Real Time Traffic report (CR61437)
We have improved the Real Time Traffic report display, and it now correctly tracks network traffic.

CIFS connections (CR61513)
The WANJet appliance no longer prematurely terminates CIFS connections. This issue caused Lotus Notes users to receive delayed write error messages.

Upgrading a one-arm configuration (CR61967)
Upgrading a WANJet appliance in a one-arm configuration no longer disables IP forwarding.

Configuring Management IP address (CR62928)
You can now successfully change a previously configured Management IP address on the Local WANJet Configuration screen.

WANJet appliance connections dropped (CR63281)
In previous versions, in a particular configuration, the WANJet appliance might generate an error causing it to lose its connections. In this release, the error no longer occurs.

Copying remote directories (CR63912)
We have improved the speed of directory copies. The WANJet appliance now further accelerates the copying of remote directories to clients' local computers.

WANJet optimization (CR64023)
After a link down and link up with a peer on low bandwidth links, the WANJet appliance now ensures that connection optimization occurs. This corrects a previous issue in which the WANJet stopped optimizing under these circumstances.

WANJet appliance failure when bridge IP address not set (CR64145)
The WANJet appliance now works correctly when you set the bridge IP address to 0 or leave it empty.

Enhancements

This release includes the following enhancements.

New roadmin account (CR64016)
The WANJet appliance includes a new restricted account called roadmin. The roadmin is a read-only user who can view the WANJet Web UI, but cannot reconfigure the appliance. (The roadmin cannot view any of the Security or System screens.) The user name and the default password for the account are both roadmin.

Only an administrator who is logged in as admin can change the roadmin password in the Web UI, or at the command line using the passwd command. There is no command line interface to the roadmin account.

Administrator account change
When changing the admin password at the command line, you are now required to type the current password before typing the new one.

Upgrade enhancements
Upgrade enhancements, such as a progress bar showing the status of the file transfer, are included in this release. You see the enhancements when you perform the next software upgrade.

When you are performing a remote upgrade from release 4.0.16 or later, you can choose a tar file instead of the remote upgrade image. Selecting the tar file causes the WANJet appliance to perform an integrity check on the source file before doing the upgrade.

Copying small files (CR64024)
The WANJet appliance now optimizes the copying of small files as well as large files. Previously, it did not accelerate the copying of files under 128K.

Hub/spoke deployment
We removed the artificial limit on the number of WANJet appliances that you can configure in a mesh or hub/spoke deployment.

CIFS optimization
We added a configuration option to disable CIFS optimization. Only F5 Systems Engineers can change this option.

Failure mode options (WANJet 400 only)
We added a new feature called Failure Mode to the Operational Mode screen. It applies only to the WANJet 400 appliance. Failure Mode has two options:

  • Fail to wire (default)
    When using Fail to wire, if there is a software failure, traffic passes through the WANJet appliance with no optimization. No traffic interruption occurs.
  • Fail close
    If you select Fail close, when a software failure occurs, the WANJet breaks the link and stops traffic from passing through the WANJet. To use this option, you must also make a hardware adjustment on the WANJet appliance.

     

Refer to Optional configuration changes for procedures on how to set these options.

Known issues

The following items are known issues in the current release.

TDR-2 optimization for concurrent connections (CR60126)
The limit of concurrent connections that TDR-2 can optimize is lower than the overall connection limit.

  • WANJet 400 appliance can optimize up to 1500 concurrent connections using TDR-2 optimization.
  • WANJet 200 appliance can optimize up to 200 concurrent connections using TDR-2 optimization.

Passthrough sessions (CR60178)
After a high volume of traffic passes through the WANJet appliance, the dashboard may temporarily display more Passthrough Sessions than are actually occurring.

VLAN configuration on a local Series 200 WANJet (CR61557)
After using the VLAN Settings link to add a VLAN to a local WANJet appliance, you cannot reach the IP address configured in the WANJet appliance virtual IP through the VLAN interface.

WANJet Links light (CR61710)
The WANJet Links light on the dashboard does not monitor WANJet appliances that are set up as redundant peers; it displays only the status of the active peer.

SSL encryption implementation (CR64020)
SSL encryption is currently implemented only for optimized TCP traffic. In future releases, we plan to support TCP and UDP protocols for SSL encryption.

VLAN traffic and LAN router value configuration (CR64021)
If you want to process VLAN traffic, do not configure a LAN Router value in the Local WANJet link of the Web UI.

SNMP support (CR64022)
We have disabled SNMP support for this release and expect to reinstate it in a subsequent version.
