This document summarizes the functions of the Integrated Management Controller (IMC) software Release 2.2.0.17. The document also provides a list of known problems. The document provides IMC first day of service (FDOS) procedure, and the procedures to upgrade or downgrade from Common Interface Module (CIM) to or from IMC module.
This document is intended for customer functional and operational groups and Cisco System Engineers responsible for installing/provisioning the Cisco MGX 8240 switch.
This section describes the steps needed to upgrade an MGX 8240 chassis running with a CIM module to a chassis running IMC cards. The steps described minimize the impact to PSM cards running in the chassis. When these steps are followed, user traffic is not affected by the upgrade. Also described is the procedure for downgrading from IMC cards to a CIM module. This procedure applies to PSM version 1.1.2.10.
Note Although the upgrade will work with VCLI version 0.38, it recommended that the VCLI is upgraded to version 2.2.X before performing the upgrade. |
This procedure does NOT describe the procedure for upgrading the switch software. See Appendix D of the Cisco MGX 8240 Hardware Installation Guide for details regarding upgrading switch software.
Upgrading from the CIM to the IMC requires a maintenance window. The upgrade requires from 1-2 hours per chassis to perform. During this time, the PSM cards may not be reachable via the out-of-band interface (ethernet). It is recommended that no configuration changes (other than those required by this procedure) be performed on the PSM cards while the upgrade is in progress.
For a chassis configured with redundancy, special steps are taken to ensure that the backup cards in a redundancy group do not perform an unwanted switch in. This is accomplished by setting the redundancy role of the backup card to none. Because the role of the backup will be set to none, it will not protect the primaries in its group during the IMC upgrade.
Warning Before the role of the backup is changed to none, its state must be standby. Failure to heed this warning will result in user traffic loss. |
Step 1 Check to make sure the backup PSMs are in standby state.

Step 2 Change the role of the backup PSMs from standby to none.
sw1[..] - VCLI>> ch ces red -role n -card BackupCard -override 1Repeat this command for all backup cards in the chassis. When the role of a backup card is changed to none, the card will reset. When all the backup cards have reset and are ready (approximately 5 minutes), verify that their roles are now none.
Step 1 Check that all the PSMs that were backups now have role none.

Step 2 Change the primary clock source from BITS A or B to OC31 on all the primaries. Verify that the timing status of OC3-1 is good before changing the timing source. If the timing source has an error, correct the error or choose a different timing source.
sw1[..] - VCLI>> sho ces ref statRepeat this command for all of the primaries in the chassis.
Step 3 Disconnect the cables connected to CIO card. The cables are the CIM cable and BITS clock cable.
Step 4 Remove the CIO card from the rear of the chassis.
Step 5 Install the IMC IO card. Use care when installing the card so that midplane pins are not bent during the installation. If you need more information, please refer to Chapter 1 of the Cisco MGX 8240 Hardware Installation Guide.
Step 6 Install the first IMC card in the front of the chassis in slot 1A (top slot). If you need more information, please refer to Chapter 1 of the Cisco MGX 8240 Hardware Installation Guide.
Step 7 Connect a dumb terminal to the IMC IO card. The serial port is located on the rear of the chassis on the IMC IO card and is the second RJ-45 port from the top of the card.
Step 8 Perform first-day-of-service (FDOS) for the IMC card. The external IP address of the IMC card will usually be the IP address of CIM. For more information, please refer to the Cisco MGX 8240 Hardware Installation Guide.
Step 9 Move the RJ-45 ethernet connection from the CIM to the IMC IO card. The location of the ethernet port is the first port from the top on the IMC IO card.
Step 10 Install the second IMC card in the front of the chassis in slot 1B (bottom slot). There is no need to perform FDOS on the second IMC card in the chassis since it automatically derives FDOS configuration from the first card.
Step 11 Connect the BITS clock source to the IMC IO card.
Note The BITS connector pinout on the IMC card is different from the pinout on the CIO module. |
Step 12 Using the VCLI, verify that the workstation can communicate with the PSM cards in the chassis. It may take up to 5 minutes before the VCLI can communicate with the PSM cards.

Step 16 The downgrade to the CIM module is complete.
This release provides a central management interface to the Cisco MGX 8240 product. The central management interface function was provided by the CIM before. The following functions are supported in release 2.2.0.17:
First day of service provisioning capability
Terminal server to connect to PSM CMDR
Network address translation
Temperature monitoring
Fan Status monitoring
Power Input monitoring
Alarm relay control monitoring
Management of IMC configuration
Inter-IMC health monitoring
1:1 IMC redundancy
Perform First Day of Service (FDOS) on the primary IMC card via the craft port interface (serial port) to verify that the switch is ready to be managed by the Network Management System.
Before starting FDOS, you need the following:
Install the front IMC card in slot 1A (top shelf). Leave the second IMC card on slot 1B uninstalled while FDOS is performed on the primary IMC card.
Step 1 Use the RS232 DCE RJ45 Connector to connect the cable between the VT-100 terminal and IMC's Craft Interface (serial port on the IMC IO back card, second from the top).
Step 2 Configure the terminal device for VT-100 with a baud rate of 9600 (8,N,1).
The Craft Interface/Console Management Diagnostic Resource (CMDR or Commander) is the menu-based tool available to set up FDOS. The menu-based tool is easily invoked when a user logs in through the serial port into the IMC. CMDR is menu based and several menus are available.
To set up the Craft Interface/CMDR, connect your VT-100 terminal (or laptop) via the RS-232c cable to the serial port on the module.
To begin FDOS, perform the following steps:
Step 1 Enter CMDR and press <Enter>.
Step 2 Enter your username and password on the Login menu (Default is sysadmin/sysadmin).
Step 3 To display the menu mode, enter menu.
This first screen will have four options (Node Setup, Administration, Help, Exit). Node Setup will be highlighted. Press <Enter>.
Under Node Setup you will have two options: Node Config and SNMP Configuration. Node Config will be highlighted. Press Enter.
You will get a Node Configuration screen that requires you to fill in information on the following:
When those are set, press shift + F1 to enter data.
You will get a Node Configuration screen that asks if you want to update the parameters now. Use the arrow key to highlight Yes. Press <Enter>.
You will get a screen that asks if you want to reboot now. Highlight Yes and press <Enter> to Reboot the IMC card.
Step 1 Enter login name and password to login to the commander. Type menu to get
to the menu mode.
Step 2 You will see two options: Manager/Trap Reporting and Community Information. Manager/Trap Reporting will be highlighted. Press Enter.
Step 3 In the NMS Trap Report Screen, New will be highlighted. Press <Enter>.
You will get the New Manager screen, which asks for the IP address of the chassis
that will receive traps. Enter IP address.
Step 4 You will get a screen which asks if you want to send the traps to the address.
Select Yes.
Step 5 Enter the port number to which traps are sent (default is 162).
Indicate whether the trap community is private or public. Press <shift + F1>.
Step 6 You will see the SNMP Config screen again. Use the arrow key to highlight
Community Information. Press <Enter>.
Step 7 You will get the "Community String Access" screen. New will be highlighted. Press <Enter>. You will get the "New Community String" screen. Fill in the name of the community string
(such as public or private). Press <Shift + F1>.
Step 8 You will get a screen that asks if you want to allow GETs, SETs, and TRAPs. The default answers are
all yes. Select Yes or No, and press <Shift + F1>.
Step 9 Press <Esc> to return to the main menu window. With the arrow keys, highlight Administration. Press <Enter>.
Step 10 You will get a screen with two options: Set System Time and Operator Access. Set System Time will be highlighted. Press <Enter>.
Step 11 You will get a screen that asks for information on the system date, time, and time zone. Set them, and press <Shift + F1>.
Step 12 To reboot, use the <Esc> key to get back to the main menu. Use the arrow key to highlight the Exit option, and press <Enter>.
Step 13 IMCCMDR> oper reboot
After FDOS is performed on the primary IMC, installing the secondary IMC automatically derives FDOS configuration from the primary. The user does not have to perform FDOS on the secondary card.
The following known problems have been fixed and/or verified in the IMC Release 2.2.0.17:
DDTS Number | Severity | Affects | Caveat |
CSCdr15813 | severe | Network Address Translation | NAT dynamic port numbers could use predefined port numbers. |
CSCdr20266 | severe | Network Address Translation | NAT did not create multiple entries for multiple trap receivers. |
Cisco MGX 8240 IMC software (Release 2.2.0.17) has some known problems. Every attempt has been made to address and resolve the problems of high severity. Below are the lists of known bugs that exist in the IMC. This list includes all outstanding problems related to the IMC modules and associated I/O ports.
DDTS Number | Severity | Affects | Caveat | Workaround |
CSCdp03325 | cosmetic | FDOS | When the time or timezone is changed on FDOS menu, asking the user to reboot IMC is unnecessary. |
|
CSCdp14532 | moderate | SNMP agent | IMC software displays the LED status of the front card when NMS/VCLI queries the LED status of the IMC IO backcard. The software should not display any LED status since there is no LED on the IMC IO backcard. |
|
CSCdp01746 | severe | CMDR | Changing IP address followed by adding a community string on the commander via craft port can cause the IMC card to hang. | Change IP and reboot IMC right away. |
CSCdm95292 | minor | VxWorks socket | ftp sessions will fail if switchover to standby IMC occurs. | Restart the ftp session. |
