Open Caveats - LocalDirector Software Version 4.2.3

This section describes possibly unexpected behavior by LocalDirector software, Version 4.2.3.

CSCdm62909

: The LocalDirector snmpwalk operation fails to fully traverse nodes in lexicographical order when starting at some nonleaf nodes.

CSCdt14979

: The configuration net command causes LocalDirector to reboot if the configuration file on the TFTP server lists both virtual and real servers.

CSCdv49047

: The cookie passive hash table entries are not being replicated to the standby unit after it completes a reboot. This behavior occurs only with the LD-420 platform.

Resolved Caveats - LocalDirector Software Version 4.2.3

All caveats listed in this section are resolved in LocalDirector software, Version 4.2.3.

CSCdt64748

: After a few probes, LocalDirector puts the real server in an efailed state, but the real server is healthy and responds to HTTP requests.

CSCdu11476

: TN3270 terminal emulation sessions are dropped in CIP router environments. LocalDirector may also run out of memory.

CSCdu17153

: HTTP GET requests with URLs longer than 256 bytes are TCP reset if the LocalDirector virtual server is configured to use the cookie-insert feature of the sticky command. The limit after this fix is set to 1480 bytes.

CSCdu33339

: SNMP management stations display a negative number for the total number of bytes on a particular virtual server when a query is done for that server.

CSCdu34336

: LocalDirector locks up after receiving DFP agent traffic if CLB virtual servers are defined.

CSCdu35390

: Content rules are not being saved properly when a write terminal command is issued.

CSCdu39666

: The failed standby LocalDirector crashed when trying to access configurations from the active LocalDirector.

CSCdu45409

: The failover environment of LocalDirector becomes unstable if the following command sequence is repeated:
: write memory
: write floppy

CSCdu60081

: After many Telnet sessions LocalDirector begins to refuse subsequent attempts to open sessions.

CSCdu64435

: Once a virtual machine has been placed into the FAILED state, HTTP probes are not sent to the real machines bound to the failed virtual machine.

CSCdu65271

: When a virtual machine configured as sticky generic is set to back up a virtual machine, also configured as sticky generic, the sticky generic option does not succeed when the primary machine fails over to the backup virtual machine.

CSCdu69896

: When the assign command is configured in LocalDirector with software Version 4.2.2 with a client netmask of 1.0.0.0, the command cannot be removed from the configuration file.

CSCdu78539

: After many show version commands are issued, the LocalDirector begins leaking channels and might freeze or reboot.

CSCdu80742

: After many write standby commands are issued, LocalDirector begins leaking channels and might freeze or reboot.

CSCdv01218

: Under some circumstances, Local Director can reach the Out of Proxy Objects state.

CSCdv06301

: You cannot do an snmpwalk operation on the cldRealMachine or cldVirtualMachine object identifier group.

CSCdv06734

: The backup virtual machine is not used if stickied to the original virtual machine.

CSCdv13093

: When you upgrade to Version 4.2.2 software, you cannot ping a real machine that is used with the static command.

CSCdv16242

: LocalDirector crashes when deleting a virtual machine with an associated content-rule while connections are being established to the virtual machines with the same IP address as the virtual machines being deleted.

CSCdv21441

: An snmpwalk operation with the cldexVirtualTotalBytes MIB object does not show all the virtual machines.

CSCdv24829

: The LocalDirector sysDescr MIB object does not return the software version information.

CSCdv30094

: LocalDirector does not reassign traffic to a real server if the client is in the real server's subnet.

CSCdv56353

: Deleting or modifying an HTTP probe definition of an HTTP probe that is actively probing, can cause LocalDirector to stop working.

Technical Assistance Center

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available through the Cisco TAC: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Inquiries to Cisco TAC are categorized according to the urgency of the issue:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.
Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.
Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.
Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

The Cisco TAC Web Site allows you to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to the following URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco services contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to the following URL to register:

http://www.cisco.com/register/

If you cannot resolve your technical issues by using the Cisco TAC Web Site, and you are a Cisco.com registered user, you can open a case online by using the TAC Case Open tool at the following URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, it is recommended that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority level 2; these classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer will automatically open a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to the following URL:

http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml

Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled; for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). In addition, please have available your service agreement number and your product serial number.
