These release notes describe the following topics:


Caveats describe unexpected behavior in Cisco LocalDirector software releases. This section lists the open and resolved caveats for LocalDirector Version 4.1.2.

Open Caveats - LocalDirector Version 4.1.2

This section describes possibly unexpected behavior by LocalDirector Version 4.1.2.

The LocalDirector proxy service does not properly complete a TCP half-close for the client side of the connection.

Invoking the write floppy command on a LocalDirector causes failover.

There is no password unlock feature for the LocalDirector 417 platform because this platform has no floppy drive.

Long-term connections are not preserved in stateful failover.

The Address Resolution Protocol (ARP) timeout value causes LocalDirector to report incorrect values at boundaries and then automatically reboots itself.

When you invoke the configure network command, LocalDirector reboots if the configuration file contains virtual and real servers.

When failover communications are disrupted, the designation of a LocalDirector unit as a primary or secondary becomes inconsistent.

LocalDirector sends an Internet Control Message Protocol (ICMP) fragmented message to the correct interface but to the wrong real server.

Resolved Caveats - LocalDirector Version 4.1.2

All caveats listed in this section are resolved in LocalDirector Version 4.1.2.

LocalDirector automatically reboots after sending traffic to an out-of-service direct IP that backs up another direct IP.

Dynamic Feedback Protocol (DFP) functionality is no longer working in LocalDirector version and later.

The backup command in LocalDirector version 4.1.1 does not work after LocalDirector is rebooted.

When you invoke the failover active command, LocalDirector toggles uncontrollably between active and standby status.

Content Load Balancing (CLB) directs requests to the wrong content server.

LocalDirector takes 6 seconds to retransmit synchronous packets to a server when that server responds with a false acknowledgment (ACK) packet.

When you upgrade LocalDirector to software Version from a diskette, the old configuration file is automatically erased from LocalDirector.

LocalDirector 417 will not boot the image from Finesse in a failover pair.

LocalDirector allows you to temporarily mark a User Datagram Protocol (UDP) real server as a DIP server. This causes the LocalDirector system to automatically reboot when you invoke the show dip command.

LocalDirector may run out of blocks with redirected traffic.

When you upgrade from LocalDirector version 4.1.1 to, LocalDirector reboots while reading the configuration file.

LocalDirector 430 automatically reboots when you test command-line interface (CLI) commands.

LocalDirector crashes when you invoke the write net command.

If the service command with the clb-close argument is enabled for a CLB virtual server, then no traffic can go to that virtual server.

LocalDirector automatically reboots when it runs out of connections.

You cannot set LocalDirector using the failover hellotime command.

The predictor roundrobin command does not work with Remote Authentication Dial-In User Servers (RADIUS).

A virtual server that is associated with a rule that has a content-string of "*" will cause LocalDirector to reboot.

Invoking the clear configuration command while content load balancing (CLB) traffic is running causes LocalDirector to automatically reboot.

LocalDirector automatically reboots immediately when CLB traffic flows abundantly.

When HTTP traffic does not match any rules defined, that traffic will be directed to the default virtual server (assuming one has been defined). This will cause LocalDirector to reboot.

The content matching code was not correctly matching the HTTP request to the correct real server.

LocalDirector automatically reboots when binding a URL to a virtual server that has a URL backup.

You cannot change the LocalDirector IP address if it is not it in the LocalDirector's subnet.

A bridge loop occurs if a crossover cable is used for stateful failover between interfaces on primary and secondary LocalDirector units.

LocalDirector automatically reboots when you invoke the clear configuration all command.

If the fail active command is issued on the secondary LocalDirector and traffic is currently being forwarded by the primary LocalDirector, the primary LocalDirector will reboot.

Clients are unable to directly access real servers that are bound to virtual servers that have rules associated with them.
