Cajun P220, P550, P550R Switch Release Notes, Release 4.0.1 3
Chapter 1 Read Me First
This section of the Release Notes Supporting the Cajun P220 and Cajun P550 family of switches
contains information that is crucial to know before proceeding to install or use the Cajun switch.
Please review the following release notes before continuing to the Overview section.
CAUTION: Release 4.0.1 embedded software requires a MINIMUM of 16 MB DRAM
(Dynamic Random Access Memory) to run on a Cajun P550 Layer 2
supervisor module. BEFORE upgrading, ensure that the switch meets this
16 MB DRAM requirement. A memory upgrade is not required for a Cajun
P550 Layer 3 supervisor module, or the Cajun P220.
CAUTION: Release 4.0.1 introduces a new ASCII configuration file format that replaces
the traditional binary (*.cfg) files used to store and restore saved
configurations. You must save your binary configuration before upgrading the
switch to Release 4.0.1 or rebooting the switch for the first time using Release
4.0.1. For information about saving your binary configuration, refer to the
“Installation” section of these release notes.
CAUTION: When making configuration changes to the switch, explicitly save changes by
copying the running configuration to the startup configuration to ensure that
the changes persist after the switch is restarted.

Additional Undocumented Features
Features in this section are not documented in the released product documentation.
BOOTP/DHCP Relay Gateway
You can Enable or Disable the BOOTP/DHCP Relay Gateway from the Enhanced CLI in Interface
mode using the command '[no] ip bootp-dhcp gateway'. From the Cajun Switch Web
Agent, this setting is located in the IP Interfaces dialog box. To open the IP Interfaces dialog box,
in the IP Configuration section of the Web Agent, click Interfaces. The default for this parameter
is Disable.
This parameter affects how the router chooses a source interface for the reception of BOOTP/
DHCP requests received on a VLAN, as this source interface determines the value that is inserted
by the router into the giaddr field and designates the IP subnet pool that the DHCP server uses
to assign an address.

The source interface is determined as follows:

Chapter 5 Installation
CAUTION: Release 4.0.1 embedded software requires a MINIMUM of 16 MB DRAM
(Dynamic Random Access Memory) to run on a Cajun P550 Layer 2
supervisor module. BEFORE upgrading, ensure that the switch meets this
16 MB DRAM requirement. A memory upgrade is not required for a Cajun
P550 Layer 3 supervisor module, or the Cajun P220.
NOTE: Release 4.0.1 introduces a new ASCII configuration file format that replaces the
traditional binary (*.cfg) files used to store and restore saved configurations. Before
upgrading the switch to Release 4.0.1, review the Installation section of these release
notes.
The following memory upgrade kits are available through your local sales representative:
Use the following procedure to upgrade from Release 3.1 to Release 4.0.1 of the Cajun P220,
Cajun P550, or Cajun P550R switch. For more detailed installation procedures, refer to the Cajun
P550/P220 Switch Installation Guide.
Downgrading to a Previous Release
1. In the CLI Configuration section of the Web Agent, click Config File Management.
In the Configuration File Management dialog box, save your Release 4.0.1 Running
Configuration (running.txt) to a TFTP server for potential later use.
2. From the Release 4.0.1 Enhanced CLI, clean the current configuration by issuing the
nvram init command.
3. Configure the switch to select the APP that contains the previous code release.
4. Reset the switch.

5. Use the CLI setup command to configure the switch.
6. Restore the binary configuration files of the release (3.1 or previous) you want to
restore. These configuration files do not reflect any changes you made to the
running configuration while using Release 4.0.1.
Problem: Release 4.0.1 of the Cajun switch contains new range-checking procedures
that may be reasonably more restrictive than those of previous releases.
Workaround: If you have a parameter in 3.1 that is outside the 4.0 range, it will be
noted in the Script Log File. After the second reboot the switch, check the Script Log File
to find out if any errors occurred as the script executed. To check the Script Log File, click
Script Log File in the CLI Configuration section of the Web Agent. If errors were
found, scroll up to find the particular error message. If you prefer to use the Enhanced
CLI, at the system prompt, type: show file logfile.txt.
NOTES:
•Some of the associated CLI command incorrectly list “Multilayer” and “3Com”.
These are not supported by the Cajun P550 48-Port 10/100 Media Module (M5548E-
100TC).
•In Release 4.0.1 of the Cajun switch, the Web Agent provides a new set of dialog
boxes in which you can:
-View startup and running configuration files
-View script execution log files
-Copy and manage configuration files
Ensure that you copy configuration files to a TFTP server or other storage location using
the Configuration File Management dialog box.
Upgrading from Release 3.1 or Previous Releases
Use the following procedure to upgrade the switch from Release 3.1 to Release 4.0.1.
NOTE: The Cajun switch does not support a direct upgrade to Release 4.0.1 from
releases prior to Release 3.0. If your switch runs a release prior to 3.0, upgrade the
switch to Release 3.0 or 3.1. Then, use the following procedure to upgrade the switch
from Release 3.0 or 3.1 to Release 4.0.1.
