ROMMON Release Notes for the WS-X45-SUP8-E


Current Release: 15.1(1r)SG—August 14, 2013

This publication describes the new ROMMON image from on the WS-X45-SUP8-E switch.

ROMMON Image Overview

ROMMON image version 15.1(1r)SG consists of new ROMMON software and FPGA images, which are supported only on WS-X45-SUP8-E.

Caveats

The followings caveat are fixed for ROMMON IOS Version 15.1(1r)SG.

None

The following caveat is open for ROMMON IOS Version 15.1(1r)SG.

With IOS Release XE 3.3.0XE (15.1.(1)XO), ROMMON supports the Fa1 management interface at 10/100/1000Mbps full duplex mode only; 10/100/1000Mbps half-duplex is not supported. This prevents the FA1 management interface from operating when connected to a hub.


Note The following ROMMON versions do not work on Supervisor Engine 8-E; only ROMMON version 15.1(1r)SG works on Supervisor Engine 8-E.


The following caveat is fixed for ROMMON IOS Version 15.0(1r)SG10.

If a switch uses a config-register ending in 0x2, it may drop into ROMMON if the bootup is interrupted by a powercycle.

Workaround: Use config-register 0x2101. CSCue19458

The following caveats are open for ROMMON IOS Version 15.0(1r)SG7.

The date command incorrect in ROMMON for Sup7-LE and WS-C4500X-32 platforms.

On Supervisor Engine 7L-E and WS-C4500X-32 with ROMMON IOS Version 15.0(1r)SG6, ROMMON cannot reliably acquire date and time information from the onboard Real Time Clock.

Workaround: None CSCtx44255

If a switch uses a config-register ending in 0x2, it may drop into ROMMON if the bootup is interrupted by a powercycle.

Workaround: Use config-register 0x2101. CSCue19458

The following caveats are fixed for ROMMON IOS Version 15.0(1r)SG7:

With ROMMON IOS Version 15.0(1r)SG7, ROMMON supports VSS.

Workaround: None. CSCuc07522

If you upgrade ROMMON with the boot statement command, the ROMMON upgrade occurs three times before IOS boots.

Workaround: None. CSCtx60355

With no service password-recovery configured, you can still interrupt the boot process with CTRL-C without erasing the configuration.

Workaround: None. CSCtu40819

The following caveats are open for ROMMON version 15.0(1r)SG6:

The date command incorrect in Rommon for Sup7-LE and WS-C4500X-32 platforms

On Supervisor Engine 7l-E and WS-C4500X-32 with ROMMON version 15.0(1r)SG6, ROMMON cannot reliably acquire date and time information from the onboard Real Time Clock.

Workaround: None CSCtx44255

The following caveat is fixed for ROMMON version 15.0(1r)SG5:

The no service password recovery command was implemented.

Workaround: None. CSCtq20729

The following caveats are fixed for ROMMON version 15.0(1r)SG2:

In a redundant switch configuration with the active supervisor engine running IOS, after the ROMMON upgrade utility completes on the standby supervisor engine, the uplinks on the active supervisor engine drop link and do not recover

Workaround: Upgrade the ROMMON version on both supervisor engines simultaneously, to ensure that the uplinks are down when during the upgrade. CSCtj54375

No persistent record exists for kernel panics (like kernel software caveats, Layer 2 hardware glitches, and DDR parity errors), making it impossible to debug when they occur.

Workaround: Connect system console to a device that saves the output. CSCtj80874

If a WS-X45-SUP7-E supervisor engine is inserted in a 4507R+E or 4510R+E chassis, ROMMON incorrectly reports the chassis as 4507R-E or 4510R-E:

Workaround: None. CSCtl74638


Note This release also supports up to 4 Gigabytes of memory and a maximum length of the ROMMON command line from 128 to 256 bytes.


Netbooting from ROMMON

Netbooting using a boot loader image is not supported. Instead, use one of the following options to boot an image:

1. Boot from an SD card by entering the following command:

rommon 1> boot slot0:<bootable_image>
 
   

2. Use ROMMON TFTP boot.


Note To use ROMON tftp boot, the TFTP server must be accessible from the Ethernet management port on the supervisor engine.


To boot from ROMMON, perform the following tasks while in ROMMON mode:

a. Ensure that the Ethernet management port on the supervisor engine is physically connected to the network.

b. Set IP address of the Ethernet management port on the supervisor engine by entering the following command: set interface fa1 ip_address ip_mask

For example, to set the supervisor engine Ethernet port with an IP address 172.16.1.5 and IP mask 255.255.255.0, enter the following command:

rommon 2> set interface fa1 172.16.1.5 255.255.255.0
 
   

c. Set default gateway for the Ethernet management port on the supervisor engine by entering the following command: set ip route default gateway_ip_address. The default gateway should be directly connected to the supervisor engine Ethernet management port subnet.

d. Ping the TFTP server to ensure that there is connectivity to the server from the Ethernet management port on the supervisor engine by entering the following command: ping tftp_server_ip_address.

e. Once the ping is successful, boot the image from the TFTP server by entering the following command: boot tftp://tftp_server_ip_address / image_path_and_file_name

For example, to boot the Cisco IOS XE image cat4500es8-universalk9.03.01.00 .SG.151-1.XO.bin located on the TFTP server 172.16.1.8, enter the following command:

rommon 3> boot 
tftp://172.16.1.8/tftpboot/cat4500es8-universalk9.03.01.00.SG.151-1.XO.bin
