Cisco recommends upgrading to Firmware Version 3.92, even with earlier Cisco IOS releases subject to N+1 Prerequisites and Restrictions such as feature interoperability, factory default configurations, etc.

Refer to the following document located on Cisco.com for further information on Firmware Version 3.92:

Release Notes for Cisco IOS Software Release 12.3 BC

http://www.cisco.com/en/US/docs/cable/cmts/ubr10012/release/notes/12_3bc/ubr10k_123bc_rn.html

Version 3.92 allocates new nvmem location to support long passwords (32 characters) and SNMP community string (64 characters).

In Version 3.92, on first reboot after migration from previous version, the new password and community string areas are installed and old settings (if any) are copied to new location.

If the user downgrades from 3.92 to a previous version, some of the configuration parameters in the newer versions are not recognized by the older software which causes the some of the config elements to be reset to default values.

If user downgrades from Version 3.92 to Version 3.80, the new nvmem location for password and community string is not recognized, and the password is removed and community string is set to private.

If the user downgrades from Version 3.92 to Version 3.60 or earlier, the password is removed and community string is set to private, and the ip address, default gateway and tftp address are reset to default values.


Note Version 3.92 is case-sensitive and stores passwords and SNMP community strings as they are entered on the CLI. In previous versions the case-sensitivity was not preserved and passwords and community strings were converted internally — passwords were stored in all uppercase and community strings in all lowercase. The parser allowed the user to type in any case as long as the letters matched.

When the user upgrades to version 3.92, the mixed case passwords and SNMP community strings from previous versions are stored as lower case characters. After the upgrade, the user should verify the password and community string and set them as desired.

Information About Cisco RF Switch Firmware Versions and Features

This topic summarizes the new commands and features for the following Firmware Versions:

Features Introduced in Cisco RF Switch Firmware Version 4.0

Features Introduced in Cisco RF Switch Firmware Version 3.93

Features Introduced in Cisco RF Switch Firmware Version 3.92

Features Introduced in Cisco RF Switch Firmware Version 3.90

Features Introduced in Cisco RF Switch Firmware Version 3.80

Features Introduced in Cisco RF Switch Firmware Version 3.60

Features Introduced in Cisco RF Switch Firmware Version 3.50

Features Introduced in Cisco RF Switch Firmware Version 3.30

Features Introduced in Cisco RF Switch Firmware Version 2.50

Features Introduced in Cisco RF Switch Firmware Version 4.0

Version 4.0 is the first release to use the combined binary image file format.

The new image file is:

1935001303a.bin — combined image format

When the RF switch recognizes the download of a combined image file, it scans the file looking for the appropriate section of the image file that applies to it. The RF switch stores the section of the download that applies to the card onto which it is loading.

Upgrades should be done via tftp download, as done in previous releases.

Version 4.0 is released on the top of version 3.93, and incorporates all of the features and bug fixes of 3.93 release.

Version 4.0 adds the following CLI command:

show port

The 10BaseT Ethernet card supports only 10Mbps operation.

Features Introduced in Cisco RF Switch Firmware Version 3.93

Version 3.93 adds support for the new Version 4.0 combined binary file downloads. This version still supports the single image formats used with the earlier cards.

Fixes for Firmware Version 3.93:

There was an error in the SHOW MODULE command that was generating incorrect status display for the last module.

The DHCP client was sending out an ARP request to 0.0.0.0, when there was a need to check if the offered address was in use.

Adjusted TFTP timeouts. The initial timeout when trying to establish a connection to the server could be too short, as it was randomly generated. Now, a minimum timeout of 1second is enforced.

Added display of the MAC address to the bootup process.

Features Introduced in Cisco RF Switch Firmware Version 3.92

Cisco RF Switch Firmware Version 3.92 provides the following changes, resolutions, enhancements, and updates, supported on the Cisco uBR10012 router with Cisco IOS release 12.3(21)BC or later:

Version 3.92 allocates new nvmem location to support long passwords (up to 32 characters) and SNMP community strings (up to 64 characters).

Version 3.92 stores passwords and SNMP community strings the way they are entered on the CLI. The user can store mixed case strings for passwords and SNMP community strings. In previous versions, passwords were stored in all uppercase and SNMP community strings were stored in all lowercase.

In Version 3.92, password and SNMP community strings may contain any of the printable ASCII characters (0x20-0x7e), with the exception of the space (0x20), double quote (0x22), semicolon (0x3b), backslash (\), and forward slash (/) characters. In addition the character '?' and `HELP' cannot be used in strings by themselves as they invoke the CLI help function.

In Version 3.92, on first reboot after migration from previous version, the new password and community string areas are installed and old settings (if any) are copied to new location. If the user moves to a previous version from 3.92, the password is removed and community string is set to private.

Version 3.92 enhances the command show log and it now includes the nvmem status message entries.

Version 3.92 introduces show password help.

Version 3.92 added reload/reboot and reload? to the main help.

Version 3.92 enhances enable password and set snmp community help and it now lists characters not recommended in these strings.

Features Introduced in Cisco RF Switch Firmware Version 3.90

Cisco RF Switch Firmware Version 3.90 provides the following changes, resolutions, enhancements, and updates, supported on the Cisco uBR10012 router with Cisco IOS release 12.3(21)BC or later:

Version 3.90 update resolves the Address Resolution Protocol (ARP) cache handling issue and ensures ARP updates after timeout.

Version 3.90 provides for enhancement in the telnet server to negotiate with the client regarding the desired setting of the echo mode. The user can set the initial state of the local echoing using the set telnet echo command. However, the telnet server can bypass this and use the client's setting if the client supports echo options negotiation.

Version 3.90 enhances the Trivial File Transfer Protocol (TFTP) to display the number of bytes as transfer progresses.

Version 3.90 pushes the CLI task priority to below that of the network task. Now, pings have higher priority than interface commands.

Version 3.90 modifies the command show version so that the full cyclic redundancy check (CRC) validation is not done on the flash contents. It now validates only the file header contents. To perform a full CRC check, use the command show files.

Version 3.90 allows RF Switch to accept passwords that match CLI keywords. In version 3.80, they were not accepted and shown as Invalid Syntax.

Version 3.90 updates real-time operating system (RTOS) kernel to be compatible with new IP stack.

Features Introduced in Cisco RF Switch Firmware Version 3.80

Cisco RF Switch Firmware Version 3.80 provides the following changes, resolutions, enhancements, and updates, supported on the Cisco uBR10012 router with Cisco IOS release 12.3(21)BC or later:

Version 3.80 adds the set access system command. This command is similar to the password system command, which is no longer valid in Version 3.80 or later. The set access system command enable access to commands that were previously available only via backdoor password. This command works in addition to any installed password, and does not override any current password protection.

Version 3.80 adds the set option to the show config command, enabling you to display the config information formatted as SET commands.

Version 3.80 introduces a new password recovery procedure.

Version 3.80 adds an all option to the show switch status command. This enables users to display detailed RF Switch status for all modules (1-28), including the last command used, the detected module position, and any relays that are in error.

Version 3.80 fixes the telnet mode so that typing the quit or exit command in a telnet session will cause the rfsw telnet server to close the connection.

Version 3.80 adds an echo option negotiation to the rfsw telnet server. The new set telnet echo command sets the default state for echoing in the rfsw telnet server. To restore the default state, us the no form of the command.

Version 3.80 adds the enable command. Using the enable command in user EXEC mode enables the user to enter privileged exec mode.

In Version 3.80, the command enable erase is changed to allow erase. This command helps to prevent accidental image erasure.

Version 3.80 adds the enable password command. This command sets enable mode password and store it in nvram. To remove the password requirement, use the no form of this command.

Version 3.80 adds the disable command. This command exits privileged EXEC mode and return to user EXEC mode, or to exit to a lower privilege level, enter the disable command in EXEC mode.

Version 3.80 adds caching of snmp mib vars to the AdminState sets/gets.

Version 3.80 adds a new mib oid to control caching.

Features Introduced in Cisco RF Switch Firmware Version 3.60

Cisco RF Switch Firmware Version 3.60 provides the following changes, resolutions, enhancements, and updates, supported on the Cisco uBR10012 router with Cisco IOS release 12.3(21)BC or later:

To help handle an increase in the SNMP traffic, Version 3.60 changes the network buffering to allocate a larger pool of (number of) buffers, with a new number of 100 buffers total.

Version 3.60 reduces the maximum packet size to 600 bytes. This combination of a larger number of buffers with smaller maximum packet size helps with handling large bursts of inbound packets that were discarded in previous versions of Cisco RF Switch Firmware.

Version 3.60 resolves a previous bug in the SNMP agent to help further with the above items. In prior versions of Cisco RF Switch firmware, the SNMP agent blocked traffic just after packet reception, waiting to allocate a buffer in which to place the output response. If no buffer was available (as would be the case if a large burst of incoming packets occurred), the agent would timeout, and the system would generate a watchdog timeout. Now, the agent uses a private buffer for the output response, and only requests a packet buffer after completing the snmp operation. If no buffer is available, the output response is discarded, and the agent continues processing inbound packets.

Version 3.60 adds the noverify option to the copy command, enabling you to override the file type verification, and place a file in either the flash (FL:) or bootflash (BF:) device. Version 3.60 updates the online help to reflect this new option. This new option provides the ability to place a copy of the main application into the bootflash, so that normal system operation is restarted in the case of a system crash, instead of having the "sys>" prompt as in previous versions of Firmware.

Version 3.60 resolves a previous issue in which concurrent access to the RF switch modules via the command-line interface and SNMP would cause random errors and crashes. The firmware now allows simultaneous usage of telnet, console, and SNMP operation. This issue was observed primarily if the show version and test module commands were used at the same time that SNMP status polling operations were occurring. This previous issue also affected a number of additional commands.

Features Introduced in Cisco RF Switch Firmware Version 3.50

Firmware Version 3.50 can be used with either Cisco IOS Release 12.2(15)BC1 or 12.2(15)BC2 for full availability of improved switchover times.

Improved Switchover Times

Firmware Versions 3.30 and 3.50 both offer significantly improved switchover times in the event of a Working interface or line card failure. Also, N+1 Redundancy is more easily configured with increased synchronization between Working and Protect interfaces. Refer to N+1 Redundancy for the Cisco Cable Modem Termination System on Cisco.com:

ARP Cache

Firmware Version 3.50 modifies Address Resolution Protocol (ARP) cache functions to reduce the number of ARP requests as possible. The ARP timeout was previously fixed at 60 seconds. This is now a definable setting from the RF Switch command-line interface (CLI). Commands relating to ARP are described later in this section.

Cisco Command Changes for Firmware Version 3.50

Version 3.50 offers the following command enhancements, continued through Version 3.60:

Added the new set arp timeout command to allow configuration of the ARP cache feature (see above).

Enhanced the show config command to display ARP timeout information.

Enhanced the show arp command. There are now three forms:

sdow arp — Displays minimal information to show valid entries in use.

show arp all — Displays more details, including link-list information and entries that may be expired.

show arp table — Displays full table, including unused entries.

Features Introduced in Cisco RF Switch Firmware Version 3.30

Firmware Version 3.30 can be used with either Cisco IOS Release 12.2(15)BC1 or 12.2(15)BC2 for full availability of improved switchover times.

Improved Switchover Times

Firmware Versions 3.30 and 3.50 both offer significantly improved switchover times in the event of a Working interface or line card failure. Also, N+1 Redundancy is more easily configured with increased synchronization between Working and Protect interfaces. Refer to the following document on Cisco.com for additional information:

N+1 Redundancy for the Cisco Cable Modem Termination System on Cisco.com:

http://www.cisco.com/en/US/docs/cable/cmts/feature/guide/uFGnpls1.html

Firmware Command Changes for Version 3.30

Version 3.30 offers the following command enhancements, continued through Version 3.60:

Replaces the configure card count command with the set slot config command for setting Cisco RF Switch slots to line cards on the router chassis.

Previously, Version 2.50 required that upstream and downstream line cards be configured to specific slots in the RF Switch chassis (using the configure card count command). Firmware Version 3.30 allows for the RF Switch chassis to be configured with any mix of upstream or downstream line cards using the set slot config command.

Adds the show ip command to display IP configuration information for the Cisco RF Switch.

Adds display of slot configuration information with the show slot config command.

Modifies the Password field output displayed in the show config Firmware command so as to preserve password security with encryption.

Modifies the Card Protect Mode field output in the show config command to change the previous notations of 1x4/1x8 to the Cisco standard notations of 4+1/8+1.

DHCP Server added for Firmware Version 3.30

Version 3.30 adds support for the DHCP server and the DHCP client, and the RF Switch Firmware no longer assumes a static IP address of 10.0.0.1 as in Version 2.50.

Features Introduced in Cisco RF Switch Firmware Version 2.50

SNMPv1 Upconverters and Traps

Version 2.50 introduces support for the Cisco 3x10 RF Switch and SNMP upconverters with the Cisco uBR10012 router. Firmware Version 2.50 fully implements SNMPv1 and Traps. SNMP traps are sent with the following events:

System startup (coldstart)

Whenever the N+1 Redundancy Unit (NRU) has completed initialization:

nruModuleOnOffNotification and/or nruModuleFaultNotification

Whenever a switchover fails:

nruModuleFaultNotification

Whenever a system crash is detected:

nruModuleOnOffNotification.999 offline

Because the system remains largely inactive unless a switchover is requested, the controller (after startup) is not able to detect a cable interface line card that is removed or has failed until told to perform some action. The controller automatically detects a line card that is inserted into the chassis. Therefore, you get automatic notification if a line card is replaced.

Default Gateway for Remote TFTP Transfer

Version 2.50 adds support for the default gateway to enable TFTP transfers of remote Firmware images.

Installing Cisco RF Switch Firmware Version 4.0

As with previous Firmware upgrades on the Cisco RF Switch, the new Version 4.0 image can be downloaded and installed via TFTP using the COPY TFTP: command. This command can be applied from either the serial console port or a via a Telnet session.

One recommended procedure for installing the upgrade is as follows:


Step 1 Copy the image to CMTS:

COPY TFTP: //<tftpserver-ip>/<userid>/1935001303a.bin BOOTFLASH:

Step 2 Setup the tftp server on CMTS:

CONF T
TFTP-SERVER BOOTFLASH:1935001303a.bin ALIAS 1935001303a.bin
END

Step 3 Setup RF Switch with tftp host, if not already set:

SET TFTP HOST <tftpserver-ip-addr>

Step 4 Remove the password that has been set on the RF Switch, only if you are loading Version 3.80:

The CLI to remove password in Version 3.80 or later is:

NO ENABLE PASSWORD

The CLI to remove password in versions prior to 3.80 is:

NO SET PASSWORD

Step 5 Install the new code update with the following command:

COPY TFTP:1935001303a.bin FLASH:

Step 6 Reboot the Cisco RF Switch to run the new version of firmware:

REBOOT

Step 7 Go to the enable prompt:

ENABLE

Step 8 Install the new firmware image into the bootflash: using the new COPY command:

COPY TFTP:1935001303a.bin BOOTFLASH:  NOVERIFY

Step 9 Reboot the Cisco RF Switch to run the new version of firmware:

RELOAD

A sample output of the reload command is given below:

Installing Cisco RF Switch Firmware Version 3.93

As with previous Firmware upgrades on the Cisco RF Switch, the new Version 3.93 image can be downloaded and installed via TFTP using the COPY TFTP: command. This command can be applied from either the serial console port or a via a Telnet session.


Note This version can be downloaded only on the 10BaseT ethernet card.


One recommended procedure for installing the upgrade is as follows:


Step 1 Copy the image to CMTS:

COPY TFTP: //<tftpserver-ip>/<userid>/rfsw_v393.bin BOOTFLASH:

Step 2 Setup the tftp server on CMTS:

CONF T
TFTP-SERVER BOOTFLASH:rfsw_v393.bin ALIAS rfsw_v393.bin
END

Step 3 Setup RF Switch with tftp host, if not already set:

SET TFTP HOST <tftpserver-ip-addr>

Step 4 Remove the password that has been set on the RF Switch, only if you are loading Version 3.80:

The CLI to remove password in Version 3.80 or later is:

NO ENABLE PASSWORD

The CLI to remove password in versions prior to 3.80 is:

NO SET PASSWORD

Step 5 Install the new code update with the following command:

COPY TFTP:rfsw_v393.bin FLASH:

Step 6 Reboot the Cisco RF Switch to run the new version of firmware:

REBOOT

Step 7 Go to the enable prompt:

ENABLE

Step 8 Install the new firmware image into the bootflash: using the new COPY command:

COPY TFTP:rfsw_v393.bin BOOTFLASH:  NOVERIFY

Step 9 Reboot the Cisco RF Switch to run the new version of firmware:

REBOOT

While rebooting, the console displays the following warning message to show that changes have been made to nvmem:

Recalling nvmem...** nvmem default(s) used (0x0c) **
**WARNING** The following non-volatile configuration memory area(s)
**WARNING** have been modified or updated:
  Ethernet/IP
  SNMP

Step 10 Set the password back on the RF Switch if you had removed it before upgrade. In Version 3.80 and later, the CLI to set enable password is:

ENABLE PASSWORD <password>


show version and show log commands help you check the upgrade. The Commands along with the RF Switch output are given below:

MIBs

MIBs for Cisco RF Switch Firmware Version 3.30

Access to the chassis line card configuration via SNMP requires the addition of the following new objects to the MIB database, summarized in Table 1. Each of these objects has these three attributes:

SYNTAX: OCTET STRING (SIZE(2))

ACCESS: read-only

STATUS: mandatory


Note Because these objects are 16-bit hex integer bitmasks, in keeping with the conventions currently used in other bitmask values, they are declared as OCTET STRING (SIZE(2)).


Table 1 MIBs Objects Required with Firmware Version 3.30 and Later.

Object
Description

nruCacheSnmpData

Value of set snmp cache command. A value of 1 in a bit position indicates that the caching is enabled. It is enabled by default.

nruUpstreamSlotConfig

Value of the upstreamslots parameter of the set slot config command. A value of 1 in a bit position indicates that the corresponding slot should expect an upstream linecard.

nruUpstreamSlotDetected

Results of line card enumeration. A value of 1 in a bit position indicates that an upstream linecard was detected in the slot. Normally, this value should equal nruUpstreamSlotConfig.

nruUpstreamSlotErrors

A value of 1 in any bit position indicates that there is a discrepancy between the configured versus the detected settings for the slot.

nruDnstreamSlotConfig

Value of the dnstreamslots parameter of the set slot config command. A value of 1 in a bit position indicates that the corresponding slot should expect a downstream line card.

nruDnstreamSlotDetected

Results of line card enumeration. A value of 1 in a bit position indicates that a downstream linecard was detected in the slot. Normally, this value should equal nruDnstreamSlotConfig.

nruDnstreamSlotErrors

A value of 1 in any bit position indicates that there is a discrepancy between the configured versus the detected settings for the slot
