These release notes support Cisco LocalDirector Version 3.2.3.
These release notes describe the following topics:
The primary purpose of Version 3.2.3 is to introduce a flash card from Productivity Enhancement Products (PEP). The PEP flash card is a half-size card that fits in an ISA connector on LocalDirector Model 416 and Model 430. All future LocalDirector Models 416 and 430 will use this new flash card.
The new flash card plugs into the LocalDirector motherboard by its 16-bit ISA connector. The new flash card is pre-assembled in the front, right-hand slot of LocalDirector.
The PEP flash card contains 4 megabytes of nonvolatile memory (Read-Only Memory or ROM) referred to as Type AMD Am29F016.
The PEP flash card also contains a BIOS Flash Memory Chip that serves as the BIOS ROM and uses 32 Kilobytes of memory. This 32 Kilobyte block of the memory map is located within the address range of 0xD8000 to 0xDFFFF. The BIOS ROM chip is referred to as Type AMD Am29F010.
The PEP flash card contains one 5-position dipswitch. The settings for the 5-position dipswitch to access the 32Kbytes of memory are:
Switch 1 | ON |
Switch 2 | OFF |
Switch 3 | ON |
Switch 4 | OFF |
Switch 5 | OFF |
Use the following table to confirm which LocalDirector software version is compatible with the new flash card.
| Software Version Number | New Flash Card |
|---|---|
3.3.2, 3.3.1, 3.2.2 and lower | Not compatible |
3.2.3, 3.3.3 and greater | Compatible |
Read Appendix B in the Cisco LocalDirector Installation and Configuration Guide.
The new PEP flash card is compatible with LocalDirector software versions 3.2.3, 3.3.3, and greater. The boot sequence with the new flash card displays two important differences. The first difference is the Finesse Bios V4.0, and the second difference is the Flash=Am29F016B @ 0x300 bank 0.
The following is an example of the LocalDirector boot sequence with the new flash card. The important differences in the display are highlighted in bold font.

Support for Accelerated Server Load Balancing (ASLB) uses the Cisco Catalyst® 6000 and Catalyst 6500 switches to accelerate Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) sessions that are load balanced by LocalDirector. LocalDirector makes the load balancing decisions and the Catalyst switch performs packet forwarding. Once packet forwarding begins on the Catalyst switch, traffic bypasses the LocalDirector and the Catalyst central processor. The ASLB feature uses the wire-speed capabilities of the Catalyst switch to deliver Server Load Balancing performance at speeds of more than 800 Mbps with up to 15 million packets per second.
 |
Note Traffic containing data packets are transparently passed by LocalDirector with the ASLB feature and there is no incrementing of DataIn counters. The data command is used to limit the number of connections to a real server that is not sending data packets. LocalDirector can fail a real server based on DataIn counters. You cannot use the data command to fail real servers that are not sending data packets with an ASLB configuration. |
To enable ASLB, use the dispatched assisted mode with the redirection command. The syntax is:
redirection virtual_id dispatched assisted
virtual_id | The IP address or name, port (if a port-bound server), bind-id, and protocol of a virtual server. |
|---|---|
dispatched assisted | LocalDirector replaces the MAC with the IP address of the real server. An aliased IP address on the real server matches the virtual IP address on LocalDirector. Address translation is not used. Dispatched mode supports UPD and TCP sessions without any change to the IP address information. |
This section describes possible unexpected behavior in Cisco LocalDirector Release 3.2.3
The following display is the result of starting the boot sequence with the new flash card and LocalDirector software version number 3.2.2. This is an example of an incompatible software version with the new flash card.
