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:

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:

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.

Cajun P220, P550, P550R Switch Release Notes, Release 4.0.1 10

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.

Cajun P220, P550, P550R Switch Release Notes, Release 4.0.1 11

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.

Cajun P220, P550, P550R Switch Release Notes, Release 4.0.1 13

Front Panel Display

Problem: The 'lastlink' application on the front panel display does not work on the
Cajun P220FE or P220G.

Workaround: Currently, no workaround is available.

Hardware

Frames Transmitted with CRC Errors

For the Cajun P550 20-port Module, Model M5520-100TX (P/N 311-0020-000: Revision Level
A or B), and the Cajun P550 12-port Module, Model M5512R-100TX, a temperature sensitivity
problem has been found when operating at 10Mbps. This sensitivity will result in the port
transmitting frames with CRC errors. These frames, since they have CRC errors, are then
dropped by the receiving station. Note that this problem only occurs at 10Mbps. 100Mbps
operation is not affected.

Software Release v1.0.17 (or later) has implemented a new configuration that disables the
power saving mode of the Phy chip. Disabling the power saving mode has the effect of moving
the operational temperature of the part past the problem range. Testing this software
configuration is 100% successful in resolving the error.

The software configuration command is only available from the CLI. It is saved in NVRAM.
Users should only disable the power saving mode for ports that are experiencing this problem.
Disabling the power saving mode for parts that are operating at a lower temperature than the
problem range may accidentally raise the temperature into the problem range. In legacy-cli
mode, use the following command to disable the power saving mode for ports:

Cajun> port set DisablePowerSave <slot>.<port> on

NOTE: To enter legacy mode, type legacy-cli at the command prompt. To return to
the Enhanced CLI from legacy mode, type exit at the command prompt.

Hot Swap Modules

Hot swapping modules may cause SEPROM and SMAC panic messages to appear in the event
log. These messages are for informational purposes only and should be ignored.

Cajun P220, P550, P550R Switch Release Notes, Release 4.0.1 14

Loopback Tests

Loopback tests on ports may fail when there is traffic present on the link at start-up.

M5520-TX Loopback Tests During Cold Start

Occasionally M5520-TX (P/N M5520-100TX) boards with a Quality Phy will fail loopback tests
when the board initially is started. The problem corrects itself as the board warms up.

M5520-TX Auto-negotiation with Xircom Adapter Cards

M5520-TX (P/N M5520-100TX) boards manufactured with a Quality Phy do not autonegotiate
with Xircom brand adapter cards. If you are having this problem, disable auto-negotiation on
the affected ports, and set the port speed and duplex state manually.

Oversized Packets

Oversized packets are not counted in itemized statistics if the packet size is between 1519 and
1548 bytes.

Short Cables May Cause Auto-negotiation Problems

You may experience difficulties with auto-negotiation between some releases of the 10/
100Base-TX Module (M5510-100FX, M5520-100TX, M5510R-100FX, M5512R-100TX) and
adapter cards using physical interfaces manufactured by National Semiconductor. The symptom
is loss of connectivity. You can address this problem by either disabling auto-negotiation, or
using a patch cable longer that 5 meters. Use the following Enhanced Command Line Interface
command in legacy mode to correct the situation:

Cajun> port set NationalPhyMode <slot>.<port> enable

NOTE: To enter legacy mode, type legacy-cli at the command prompt. To return to
the Enhanced CLI from legacy mode, type exit at the command prompt.

NOTE: The factory default for ports now sets the National Phy mode to enabled.

Cajun P220, P550, P550R Switch Release Notes, Release 4.0.1 15

Intelligent Multicasting

Problem: Intelligent Multicasting can block protocols to non-multicast routers. If you
have enabled Intelligent Multicasting and configured a VLAN attached to one or more
non-multicast routers or multicast-capable endstations, Intelligent Multicasting will
configure router ports where multicast-enabled routers reside. These multicast router
ports are necessary to allow all multicast packets to the adjacent multicast routers. Non­multicast enabled routers will not be considered router ports, and will not receive
multicast traffic for which an Intelligent Multicast session was created. The problem can
arise when multiple IP multicast addresses map to the same multicast MAC address,
resulting in protocol packets not being sent to the adjacent non-multicast enabled
routers.

EXAMPLE:

The unicast routing protocol in use on all connected routers is OSPF, and all ports are on
the same VLAN. An endstation joins the IP multicast group 226.128.0.5 on port 1. The
MAC address for the group is 01:00:5E:00:00:05. IGMP snooping creates a session for
this MAC address, with port 1 as the client port. There is a non-multicast OSPF router
attached to port 2. OSPF uses the IP multicast link-scoped group 224.0.0.5, which also
maps to a MAC address of 01:00:5E:00:00:05. Because port 2 is not a router port, and it
is not part of the 01:00:5E:00:00:05 session, the switch will only pass OSPF messages out
port 1.

Other protocols, such as the Service Location Protocol (RFC 2608), use 224.0.1.22 and

224.0.1.35, which can be blocked by endstations joining sessions that map to the same
MAC address.

Workaround: Make certain that all ports connected to a router are configured as router
ports to ensure that all router-to-router messages will not be blocked. If other non­router protocols such as the Server Location service are in use, create static sessions as
needed. Also, do not create static sessions that will conflict with the protocols in use on
your network. For a complete list of internet multicast addresses recognized by the
IANA, go to http://www.isi.edu/in-notes/iana/assignments/multicast-addresses.

NOTE: By default, the default “Rate Limiting” state for 10/100 Megabit ports is
Enabled, and multicast traffic is rate-limited (to 20%) on 10/100 Megabit ports. When
transmitted from these ports, multicast traffic is rate-limited unless Intelligent
Multicasting is enabled. If Intelligent Multicasting is enabled, the multicast traffic for
which the Intelligent Multicast session was created will not be subject to rate limiting
unless the rate limiting state is set to Enabled (all multicast included). If you do not
want to enable rate limiting of multicast traffic on a port, either 1)Enable Intelligent
Multicasting, or 2) Disable Rate-limiting on the port.

Cajun P220, P550, P550R Switch Release Notes, Release 4.0.1 16

OSPF

Problem: Upgrading the switch from a Release 3.1 or other previous release to Release

4.0.1 may cause the loss of your virtual link configuration.
Workaround: After upgrading and resetting the switch, view your running

configuration to ensure that virtual links are intact. (To view your running
configuration, click Running Config in the CLI Configuration section of the Web
Agent.) If the virtual link configuration is lost, reconfigure the virtual links.

NOTES:

• When the Cajun P550 first boots up as an ABR or ASBR, it may send an ASBR
advertisement for itself. This advertisement is later flushed by the system.

• When changing the OSPF Router ID, the Cajun P550R does not immediately flush
the advertisements with the original Router ID. Instead these advertisements will be
flushed when they are aged from the database.

• When a virtual link is created on the Cajun P550R router, the router cannot detect if
the remote router is an ABR to area 0.0.0.0.

• There may be a loss of Web connectivity for about 10 seconds during LSA updates in
a large OSPF network.

Piggyback Ports

NOTE: If a router port for intelligent multicasting is mirrored with a piggyback port, the
piggyback port is listed instead of the router port.

RMON

NOTE: On Gigabit Ethernet port, under heavy utilization, 30 minute RMON stats always
show utilization as 0.

Cajun P220, P550, P550R Switch Release Notes, Release 4.0.1 17

SNMP

NOTES:

• Cold start traps cannot be transmitted out of inband interfaces when Spanning Tree
is enabled.

• ipAddrTable does not display inactive interfaces (VLANs). An inactive interface
occurs when there are no active ports on a VLAN.

• You cannot have more than 10 SNMP community strings per switch.

Spanning Tree

NOTES:

• The Cajun P550 48-port Media Module (M5548E-100TC) supports Spanning Tree
for each group of eight ports at the internal switch port. Spanning Tree functionality
is disabled by default. If per-port STP is required, it is recommended that you use a
Cajun P550 20-port Module (M5520-100TX) or Cajun P550 Layer 3 12-port Copper
Module (M5512R-100TX).

• Release 4.0.1 does not allow modification of the Spanning Tree and Fast Start
features on the CPU switch port. When you modify all switch ports, the Spanning
Tree and Fast Start features will be not be applied for the CPU switch port and the
corresponding status line does not display.

• Spanning tree convergence may take longer than 30 seconds in complex networks
after a topology change

Problem: When IEEE 802.1D spanning tree is used with hunt groups, the non-flood
ports are shown as forwarding, even if the hunt group is blocked.

Workaround: The flood port of the hunt group shows the actual state of the spanning
tree. View the flood port to see the actual state of the spanning tree.

Cajun P220, P550, P550R Switch Release Notes, Release 4.0.1 18

PPP and Telnet

NOTES:

• A Telnet session to the serial port via PPP may time out during attempts to transfer
large files, such as executable images, to a TFTP server over the same link. However,
the file transfer is not terminated. An in-progress TFTP file transfer continues and
ends only after the file transfer is completed.

• File transfer via TFTP over PPP links may terminate before completion if the dialin
PC is used TFTP server.

• A new baud rate may take effect before the current PPP connection is terminated if
the relevant baud rate change command is entered more than once resulting in
termination of PPP connection. This requires re-establishment of a PPP connection.

Time Zones

Problem: The System Clock may be incorrect after an upgrade to 4.0.
Workaround: Check the System Clock and reset it, if necessary. For information about

resetting the System Clock, refer to the Cajun P550/P220 Switch Operations Guide.

Problem: To support SNTP, the internal clock was changed from local time to GMT. The
System Clock is now displayed by converting the internal representation (GMT) to local
time by accounting for time-zone and summer-time hour configurations.

An upgrade routine has been added that changes the System Clock for all switches
running 3.0 or higher, given the following assumptions:

• The switch is running Release 3.x,

• The time-zone is set properly in the 3.x image, and

• The time-zone defined supports the North American Daylight Savings Time rules.

If any of these assumptions are false, the System Clock will be incorrect.

Workaround: Check the System Clock and reset it, if necessary. For information about
resetting the System Clock, refer to the Cajun P550/P220 Switch Operations Guide.

Cajun P220, P550, P550R Switch Release Notes, Release 4.0.1 19

VLAN Issues

NOTE: If the Switch Port attribute Automatic VLAN Creation is set to Enabled, the
Allow Learning attribute must also be set to Enabled.

Configuring VLANs

NOTES:

• In certain large configurations, the switch powers up very slowly.

• If you set a port’s VLAN trunking mode to Clear, make sure not to change the VLAN

Binding Type from the default value: Static.

• If you are using both the VLAN auto-learning feature and the Binding Type Bind to
Received or Bind to All, make sure that you set the binding type before you set
Auto-learn to enable or else the port may not be automatically added to the VLAN.

Duplicate VLAN Error Message

NOTE: When you add a VLAN and then refresh your browser page, you may receive an
error message stating that the VLAN name is already in use.

IEEE 802.1Q Packets

Problem: When a tagged IEEE 802.1Q packet arrives on a port that is “bind-to-all” and
the VLAN does not exist on the switch, the packet is forwarded on to the VLAN assigned
to the port default VLAN for that port.

Workaround: To prevent unintended forwarding of unknown VLAN traffic to the port
default VLAN, configure the port default VLAN to the “discard” VLAN. However, please
note that automatic VLAN creation will not work if the port default VLAN is the
“discard” VLAN, because the switch does not learn for this VLAN.

Chapter 7 Functional Restrictions

This section provides information on all of the functional restrictions of the Release 4.0.1 switch
software. The functional restrictions are documented alphabetically by functional area (for
example, VLANs, DVMRP, IP).

Hardware

Gigabit Ports Do Not Perform Auto-negotiation

Cajun Gigabit Ethernet ports operate at 1 Gbps, full duplex and have been widely tested for
interoperability with other devices. Currently, these ports do not support auto-negotiation. If you
connect a Cajun gigabit port to a device that supports auto-negotiation, you must disable auto­negotiation on the non-Cajun device to ensure proper operation.

Hot Swapping Modules

If your switch supports a large configuration file, such as the startup.txt file, inserting and
configuring a new module while the switch is operational may cause console and telnet CLI
sessions to pause momentarily.

Link Status

When a large number of VLANs or endstations are on a hunt group, it may take several seconds
for the link status LED to change upon failure.

Ping

Unable to Ping the Inband Interface on a Layer 2 device. This problem does not occur with Layer
3 devices or with the Out of Band Interface.

Cajun P220, P550, P550R Switch Release Notes, Release 4.0.1 21

Redundant Controller Support

In the event that the redundant switch controller fails, the switch will reset itself.

Auto-Negotiation

Some network cards do not auto-negotiate correctly with older releases of the 10/100TX
modules. This is evidenced by the reception of CRC errors on the mirror port. To avoid this
situation, disable auto-negotiation and manually configure the speed and duplex of the mirror
port and network card.

Spanning Tree

IEEE 802.1D Spanning Tree

IEEE 802.1D spanning tree does not work with 3Com tags.

Web Configuration

The Disable Spanning Tree option available from the “spanning tree> vlan> port” the Cajun
Switch Web Agent disables the port. To disable Spanning Tree mode for the port, use the
“Modules and Ports > Switch Ports” Web page. When disabling the Spanning Tree for a port,
BPDUs received on that port are ignored and BPDUs are not generated by the switch for that
port. The port will move directly into the forwarding state from the disabled state. The port does
not trigger a topology detection change.

Setting the Spanning Tree Mode

When the Spanning Tree mode is set to IEEE 802.1D, BPDUs are sent out ports in Clear (non­trunked) format even if the port has a trunking format (3Com, IEEE 802.1Q, or Dual-Layer)
defined.

Cajun P220, P550, P550R Switch Release Notes, Release 4.0.1 22

For ports that have a 3Com trunking format, the receiving end of the trunked port attempts to
interpret the clear BPDUs as trunked packets. Consequently, these BPDUs are discarded at the
receiving end. For Spanning Tree to function properly with 3Com trunked ports, the Spanning
Tree mode should be set to per-VLAN. In per-VLAN Spanning Tree, there is one instance of
Spanning Tree for each VLAN and the BPDUs are tagged with the VLAN ID, ensuring they are
interpreted correctly on the receiving end.

NOTE: Although this restriction does not apply to ports that use IEEE 802.1Q or Multi­Layer trunking modes, it is still recommended that you set Spanning Tree to per-VLAN
when using trunked ports. This prevents an entire link from being blocked when there is
a loop in one VLAN.

TFTP

File Naming Standard for Embedded NVRAM File System

NOTE: All NVRAM files must use an 8.3 format for file names.

When downloading code to the NVRAM file system, use standard 8.3 file naming conventions
(the default download file names do not use this convention).

TFTP Download Status Delay

It takes a few seconds before the Status button on the TFTP Download screen returns accurate
information.

Chapter 8 Bug Fixes

The following bugs issued in Release 3.1 were fixed in Release 4.0.1.

• Switch crashes with a large number of OSPF LSA’s (over 3000) on the L3 Switch.
This has only occurred for one very large customer network and can be easily
identified by the crash log submitted to technical support.

• Secondary IP Addresses on L3 switch do no display the correct index value via SNMP.

• You cannot specify a subdirectory when TFTP saving a configuration.

• The DHCP Proxy agent on the L3 Switch does not forward a NACK response from a

DHCP server.

• Hung HTTP Processes can cause a loss of TCP Connectivity over time.

• The L2 Fault Tolerant switch may fail over to a Redundant Controller under heavy

sustained traffic loads. If a subsequent incorrect failure is detected on the second
Controller, networking problems could occur.
