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.

Cajun P220, P550, P550R Switch Release Notes, Release 4.0.1 6

The source interface is determined as follows:

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.

Cajun P220, P550, P550R Switch Release Notes, Release 4.0.1 9

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 (M5548E100TC).

• 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.

7. Save your Release 3.1 binary configuration file: a. In the Memory Subsystems section of the Web Agent, click TFTP Update. b. In the TFTP Server IP Address field, enter the IP address of the TFTP server to

which you will upload the 3.1 binary configuration file.

c. In the Filename field, specify the destination path and filename of the

configuration file. This is the TFTP server path.

d. In the TFTP Target Section pull-down menu, select Save Configuration

(binary). e. Click the Update button. f. Click the Status button. View the Transfer Completed message in the System

Status frame of the TFTP Update dialog box.

8. In the Memory Subsystems section of the Web Agent, click TFTP Update. In the TFTP Update dialog box, download V4.0 onto your switch (into either APP1 or APP2).

9. Configure the switch to choose the appropriate APP (that contains V4.0 code) at the next reboot.

10. Reset the switch to load the V4.0 image.

11. Refresh your Web browser window.

12. Verify the existence of the startup.txt file in NVRAM: in the CLI Configuration section of the Web Agent, click Startup Config.

NOTE: The script log file (a new feature of Release 4.0.1) records the output of scripts executed on the system, including the startup.txt file. Upon initial upgrade to Release

4.0.1, the script is generated but not run, and output is not initially recorded in the file.

13. In the CLI Configuration section of the Web Agent, click Script Log File. Scroll to the bottom of the Script Log File to find out if any errors occurred as the script executed. If errors were found, scroll up to find the particular error message.

Chapter 6 Problems and Workarounds

The following problems and workarounds generally apply to all Cajun switches unless expressly specified.

Cajun 48-Port 10/100 Media Module

Problem: Due to the positioning of the Cajun P550 48-Port Media Module (M5548E100TC) as a high-density desktop connectivity module, the following functionality is not supported:

• Multi-layer and 3Com trunk mode

• Link aggregation (hunt groups)

• Port mirroring

• 3Com mapping table selection

• Flow control setting of "Enable with Aggressive Backoff"

• PACE priority mode

• Spanning tree mode (disabled by factory default; enabled in other cases)

• Port statistics: intra-BCM5308 unicast frames not reflected

Additionally, flow control and rate limiting available only on a per-module basis

Workarounds:

• If link aggregation is required over a 10/100TX Link, use a Cajun P550 20-port Module (M5520-100TX) or a Cajun P550 Layer 3 12-port Copper Module (M5512R100TX).

• If a port is inadvertently configured to use Multilayer tagging, reconfigure the port to use either Clear or IEEE 802.1Q tagging. To reconfigure the port from the Enhanced CLI, enter the following command at the system prompt:

set port trunking-format {<mod-num>|<mod-port-range>}[...[,]{<modnum>|<mod-port-range>}] { clear | ieee-802.1Q}

Cajun P220, P550, P550R Switch Release Notes, Release 4.0.1 12

If a port is inadvertently configured to use 3Com tagging, use the following procedure:

1. Reconfigure the port to use either Clear or IEEE 802.1Q tagging.

2. Copy (Save) the Running-Config to the Startup-Config.

3. Reboot the switch.

NOTES:

• 3Com VLT Tagging is not supported but can be enabled on the Cajun P550 48-port Media Module’s (M5548E-100TC) internal switch ports by using the Web or CLI management interface.

• The Cajun P550 48-port Media Module (M5548E-100TC) has been optimized for desktop connections. Spanning Tree topology change convergence time can be lengthy. This could lead to loss of connectivity and/or wrongful flow of data.

Command Line Interface

The command "set vlan <vlan-id> <port>" is used to bind additional ports to a VLAN if trunking is enabled on that port. To set the port default VLAN for a port, use "set port vlan

{<mod-num>|<mod-port-range>}[...[,]{<mod-num>|<mod-port-range>}] <vlan-id>".

Cajun DocServer

NOTE: Release notes for the Cajun DocServer incorrectly excludes mention of the P550 platform. Both the Cajun P550 and P220 platforms are supported.

DVRMP

NOTE: The Cajun P550R Switch may lose a small number of DVMRP neighbor-toneighbor probe messages which may cause multicast routing instability under heavy loads.
