Configurable COM 1 Port

Configuring Kernel Core Dumps

MDS 9506 Chassis

The Cisco MDS 9506 has a 6-slot chassis with the same features as the Cisco MDS 9509. It has space for two supervisor modules, and four switching or services modules. However, the power supplies are located in the back of the chassis, with the Power Entry Modules (PEMS) in the front of the chassis for easy access.

See the Cisco MDS 9500 Series Hardware Installation Guide.

CWDM/SFPs

The Cisco MDS 9000 Family supports Cisco Coarse Wavelength-Division Multiplexing (CWDM) Small Form-factor Pluggables (SFPs). Cisco CWDM SFPs allow enterprise companies and service providers to provide scalable and easy-to-deploy Gigabit Ethernet and Fibre Channel services in their networks. The main features of the Cisco CWDM SFP are as follows:

Supports both Gigabit Ethernet and Fibre Channel (1Gigabit and 2 Gigabit).

Matches wavelength plan of Cisco CWDM GBICs and Cisco CWDM OADMs.

Fixed wavelength SFPs—eight different SFPs.

Hot-swappable input/output device that plugs into a Gigabit Ethernet and Fibre channel SFP ports or slots of a Cisco switch/ router, linking the port with the network.

Cisco CWDM SFPs can be used and interchanged on a wide variety of Cisco products and can be intermixed in combinations of 1000BASE-SX, 1000BASE-LX/LH, or 1000BASE-ZX on a port-by-port basis.

See the Cisco MDS 9000 Family Hardware Guides.

IP Services Module

The IP Storage (IPS) services module (IPS module) allows you to use FCIP and iSCSI features. It integrates seamlessly into the Cisco MDS 9000 Family, and supports the full range of features available on other switching modules, including VSANs, security, and traffic management.

See the Cisco MDS 9000 Family Hardware Installation Guides and the Cisco MDS 9000 Family Configuration Guide.

iSCSI and FCIP

The Cisco MDS 9000 Family IP services module integrates seamlessly into the Cisco MDS 9000 Family of Multilayer Directors and Fabric Switches. It delivers both Fibre Channel over IP (FCIP) and iSCSI IP storage services and is configurable on a port-by-port basis.

FCIP highlights

Simplifies data protection and business continuance strategies by enabling backup, remote replication, and disaster recovery over WAN distances using open-standard FCIP tunneling.

Improves utilization of WAN resources for backup and replication by tunneling up to 3 virtual Inter Switch Links (ISLs) on a single Gigabit Ethernet port.

Reduces SAN complexity by eliminating the need to deploy and manage a separate remote connectivity platform.

Preserves Cisco MDS 9000 Family enhanced capabilities including VSANs, advanced traffic management, and security across remote connections.

iSCSI highlights

Extends the benefits of Fibre Channel SAN-based storage to IP-enabled servers at a lower cost point than possible using Fibre Channel interconnect alone.

Increases storage utilization and availability through consolidation of IP and Fibre Channel block storage.

Transparent operation preserves the functionality of legacy storage applications such as zoning tools.

Extending the Benefits of Fibre Channel SANs

Supports iSCSI drivers listed in this URL:
http://www.cisco.com.

See the Cisco MDS 9000 Family Configuration Guide.

Zoning

The switch's zoning implementation extends the VSAN and zoning concepts from the Fibre Channel domain to also cover the iSCSI domain. This extension includes both iSCSI and Fibre Channel features and provides a uniform, flexible access control across a SAN.

The iSCSI interface can be configured to identify hosts based on symbolic node name of the iSCSI host.

See the Cisco MDS 9000 Family Configuration Guide.

CDP

The Cisco Discovery Protocol (CDP) is an advertisement protocol used by Cisco devices to advertise itself to other Cisco devices in the same network. CDP runs on the data link layer and is independent of layer 3 protocols. Cisco devices that receive the CDP packets cache the information to make it is accessible over CLI and SNMP.

CDP is supported on the management Ethernet interface on the supervisor module and the Gigabit Ethernet interface on the IPS module. CDP is a highly-available component.

See the Cisco MDS 9000 Family Configuration Guide.

New CLI Commands

Several new CLI commands introduced to support the IPS module are addressed in the Cisco MDS 9000 Family Configuration Guide (Chapter 17, "Configuring IP Services"). Other commands introduced or significantly updated in Release 1.1.(1) are addressed in this section.

The do Command

Using the do command, you can execute an EXEC mode command from a configuration mode or submode prompt. You can issue this command from any submode within the configuration mode. When in configuration mode (or in any submode), enter the do command along with the required EXEC mode command. The entered command is executed at the EXEC level and the prompt resumes its current mode level.

The do command applies to all EXEC mode commands other than the end and exit commands. You can also use the help (?) and command completion (tab) features for EXEC commands when issuing a do command along with the EXEC command.

See the Cisco MDS 9000 Family Configuration Guide (Chapter 2, "Before You Begin").

The purge module Command

The purge module command clears the configuration for any module that previously existed in a slot and has since been removed. While the module was in that slot, some parts of the configuration may have been stored in the running configuration and cannot be reused (for example, IP addresses), unless it is cleared from the running configuration.

To delete the configuration in a specific module, issue the purge module slot running-config command from EXEC mode. Once this command is issued, the running configuration is cleared for the specified slot. This command will not work on supervisor modules or on any slot which currently has a module. This command only works on an empty slot (where the specified module once resided).

See the Cisco MDS 9000 Family Configuration Guide (Chapter 6, "Managing Modules").

The discover custom-list Command

The SCSI LUN discovery feature is initiated on demand, through CLI or SNMP. This information is also synchronized with neighboring switches, if those switches belong to the Cisco MDS 9000 Family.

With Release 1.1(1), you can specify a custom-list option to initiate this discovery. Customized discovery consists of a list of VSAN and domain pairs that are selectively configured to initiate a discovery.

See the Cisco MDS 9000 Family Configuration Guide (Chapter 22, "Discovering SCSI Targets").

Configurable COM 1 Port

The COM 1 port is available in Cisco MDS 9000 Family switches, and enables you to connect to an external serial communication device, such as a modem. You can configure the switch using the line com1 command in configuration mode.

See the Cisco MDS 9000 Family Configuration Guide.

Configuring Kernel Core Dumps

When a module's operating system (OS) crashes, it is sometimes useful to obtain a full copy of the memory image (called a kernel core dump) to identify the cause of the crash. When the module experiences a kernel core dump it triggers the proxy server configured on the supervisor. The supervisor sends the module's OS kernel core dump to a Cisco Netserver application. Similarly, if the supervisor OS fails the supervisor sends its OS kernel core dump to the Cisco Netserver application. You can configure the external server using the kernel core target command and the module using the kernel core module command in configuration mode.

See the Cisco MDS 9000 Family Configuration Guide.

Limitations and Restrictions

The following limitations and restrictions apply to all switches in the Cisco MDS 9000 Family:

SPAN

The following SPAN features are disabled:

Source interfaces (physical, port channels, sup-fc) and source VSANs cannot be configured in the same SPAN session.

Interface level VSAN filters on SPAN sources are not supported.

The following behavior is enforced when a configuration is saved from Release 1.x to Release 1.1(1)

If a session has both source interfaces and source VSANs configured then all the source vsans are removed from that configuration session.

The source interfaces that have interface level VSANs filters are removed from the session in all directions in which the filters are configured.

See the Cisco MDS 9000 Family Configuration Guide.

IPS Module Backward Compatibility

The IPS module is compatible with SAN-OS Release 1.1.1 and above.

To revert to Release 1.0(4) or earlier from Release 1.1(1), follow these steps:


Step 1 Power down all IPS modules using the poweroff module slot command.

Step 2 Remove any IPS module related configuration (for example, FCIP links, targets, initiators, or any other FCIP or iSCSI feature). See Chapter 17, "Configuring IP Storage" Cisco MDS 9000 Family Configuration Guide.

Step 3 Save the configuration using the copy running-config startup-config command to save the new configuration into nonvolatile storage.

Step 4 Continue with the manual downgrade procedure. See Chapter 5, "Software Images" in the Cisco MDS 9000 Family Configuration Guide.


The auto-sync Option

The auto-sync option is disabled by default. If you are replacing a faulty supervisor module, ensure that the auto-sync option is enabled so the software versions on both modules synchronize automatically. Once the supervisor synchronization is complete, ensure to disable this option.

If one supervisor module is functioning and the other is not, boot the functioning supervisor module. Then use the booted supervisor module to bring up the supervisor module that is stuck. Issue the reload module slot force-dnld command (after you log into the switch) where slot is the slot number of the stuck supervisor module. If the auto-sync option is disabled, the supervisor modules will not synchronize automatically. In this case, enable the auto-sync option before issuing the reload module slot force-dnld command. Once the synchronization is complete, ensure to disable this option.

See the Cisco MDS 9000 Family Configuration Guide.

IPS Module

FCC is not supported on switches that have an IPS module.

Each IPS module can only have 10 configured pWWNs per initiator, 1600 sessions, and 800 iSCSI hosts. Exceeding these figures may result in unpredictable consequences.

Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdx67484

Open Caveats

CSCdz31332

Symptom: If automatic image synchronization is enabled, and the standby supervisor module is synchronizing the image from the active supervisor, the switch won't stop the user from issuing the reload command on the active or standby supervisor modules. This may result in a failure to synchronize the images.

Workaround: Be sure to allow sufficient time for the images to be synchronized before reloading a supervisor module.

CSCdz12179

Symptom: When the Fabric Manager or Device Manager is run through VPN or any NAT scheme, a generic error occurs while adding duplicate zone members from a VPN connection.

Workaround: None. If an error occurs while running through VPN/NAT, all errors will show up as generic errors without a detailed message describing the error.

CSCdz43707

Symptom: The Fabric Manager or Device Manager reports an error for all operations if the switch is multihomed (both IPFC based in-band management and the out-of-band management interface are up) and the Fabric or Device Manager was started using the IP-FC address. Typically, you will see a notInTime window error in the Device Manager and all sets fail.

Workaround: If the switch is multihomed, then start the Fabric or Device Manager on the switch using the out-of-band address.

CSCdz43106

Symptom: The counter values freeze if the Device Manager port monitor window has been up and running for a long time (overnight or a few days).

Workaround: Close the frozen Device Manager window and open a new session.

CSCea45726

Symptom: The Device Manager shows a port in the down state (red square) when the operational status of the port is up. This rare occurrence is due to the failure cause of the port not being empty (for example it reflects the "initializing" state).

Workaround: None.

CSCea82028

Symptom: When the Device Manager has been running for a long time and the switch has been upgraded during this time, a Java error of class cast exception starts occurring at some point. When this error occurs, some Device Manager menu items are unusable while other menu items remain in this error state.

Workaround: Reopen the switch in the Device Manager from the open dialog to prevent this error.

CSCeb07573

Symptom: The Fabric Manager map shows incorrect links between switches. This may be caused by duplicate domain IDs in two or more VSAN islands.

Workaround: Either reconnect the VSAN islands or force one of the duplicate domains to pick a different domain ID.

CSCeb01264

Symptom: When you issue the copy startup-config running-config command on a switch which is already up and running, the trunking ports may flap. This happens due to the reapplication of allowed VSANs for trunking ports in the startup configuration.

Workaround: Ensure that the startup configuration does not contain any allowed VSAN configuration for trunking ports (trunking ports default to the allowed VSAN configuration).

CSCeb05095

Symptom: If a copy running-config startup-config command is issued when a switching module is temporarily down, the configuration for that module will be deleted from the system. This is visible if the command is issued at boot time before all the modules are online.

Workaround: First issue the show module command to ensure that all modules are online before issuing a copy running-config startup-config command.

CSCeb17094

Symptom: The following configurations are not allowed:

If a member port has subinterfaces, then the member port cannot be added to any PortChannel.

If a member port is part of a PortChannel, then you cannot create subinterfaces in this member port.

If a Gigabit Ethernet port is part of a PortChannel, then you cannot create a different PortChannel on its adjacent port.

Workaround: Do not perform these PortChannel related configurations. If you do have one of these configurations, remove it to avoid unexpected results.

CSCeb18262

Symptom: After issuing the fcdomain manager restart disruptive command, the IBM tape 3590 port on switch displayed a not connected status.

Workaround: Bring up the port by issuing the shut command followed by the noshut command on that port. For example:

switch# config t
switch(config)# int fc1/1
switch(config)# shut
switch(config)# no shut

CSCeb16270

Symptom: Avoid using the same TCP port number for iSCSI and FCIP protocols on a port. Doing so can cause unexpected behavior.

Workaround: None.

CSCeb01112

Symptom: Importing the ASCII configuration multiple times in the same switch can cause the FCIP interface to go into error disabled state.

Workaround: None.

CSCeb18066

Symptom: If you change the iSCSI switchport identification from name to IP address, the sessions do not go down

Workaround: None.

CSCea60652

Symptom: Both no pwwn hh:hh:hh:hh:hh:hh:hh:hh and no pwwn auto number delete all the pWWNs for a given target.

Workaround: None.

CSCea80896

Symptom: The Device Manager does not support iSCSI TCP parameters configuration and display.

Workaround: None.

CSCeb10797

Symptom: When you delete a pWWN for an auto-created iSCSI initiator using the Device Manager, the pWWN disappears from DM (removed from snmp fcAddress table), but still shows in the CLI (the initiator is still auto-created).

Workaround: None.

CSCeb19609

Symptom: After pulling out or plugging in a Gigabit Ethernet cable multiple times the PortChannel gets isolated and issues a remote domain manager not responding error.

Workaround: None.

CSCeb19588

Symptom: Sometimes, the zone merge import command results in isolation.

Workaround: Reissue the command to resolve the isolation.

CSCeg61535

Symptom:The Telnet server may not be disabled even if you disable it through setup. A telnet session will still work in the switch.

Workaround: Issue the no telnet server enable command in configuration mode to disable telnet after you login to the switch.

CSCei25319

Sympton: An error message in the log file occurs because the platform manager component passes the wrong parameter while responding to a SNMP query. In some cases, this results in the query not being responded to.

Workaround: Perform a refresh on Device Manager to clear the problem.

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: the Cisco TAC website and the Cisco TAC Escalation Center. The type of support that you choose depends on the priority of the problem and the conditions stated in service contracts, when applicable.

We categorize Cisco TAC inquiries according to urgency:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration. There is little or no impact to your business operations.

Priority level 3 (P3)—Operational performance of the network is impaired, but most business operations remain functional. You and Cisco are willing to commit resources during normal business hours to restore service to satisfactory levels.

Priority level 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively impacted by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Priority level 1 (P1)—An existing network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Cisco TAC Website

The Cisco TAC website provides online documents and tools to help troubleshoot and resolve technical issues with Cisco products and technologies. To access the Cisco TAC website, go to this URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC website.

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

If you have Internet access, we recommend that you open P3 and P4 cases online so that you can fully describe the situation and attach any necessary files.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. 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 automatically opens a case.
