DESCRIPTIONOF SOFTWARE FEATURES
The switch provides a wide range of advanced performance enhancing
features. Flow control eliminates the loss of packets due to bottlenecks
caused by port saturation. Broadcast storm suppression prevents
broadcast traffic storms from engulfing the network. Untagged (portbased), tagged, and protocol-based VLANs, plus support for automatic
GVRP VLAN registration provide traffic security and efficient use of network
bandwidth. CoS priority queueing ensures the minimum delay for moving
real-time multimedia data across the network. While multicast filtering
provides support for real-time network applications.

BACKUPAND
RESTORE
You can save the current configuration settings to a file on the
management station (using the web interface) or an FTP/TFTP server
(using the web or console interface), and later download this file to restore
the switch configuration settings.
AUTHENTICATION This switch authenticates management access via the console port, Telnet,
or a web browser. User names and passwords can be configured locally or
can be verified via a remote authentication server (i.e., RADIUS or
TACACS+). Port-based authentication is also supported via the IEEE
802.1X protocol. This protocol uses Extensible Authentication Protocol over
LANs (EAPOL) to request user credentials from the 802.1X client, and then
uses the EAP between the switch and the authentication server to verify
the client’s right to access the network via an authentication server (i.e.,
RADIUS or TACACS+ server).
Other authentication options include HTTPS for secure management access
via the web, SSH for secure management access over a Telnet-equivalent
connection, SNMP Version 3, IP address filtering for web/SNMP/Telnet/web
management access, and MAC address filtering for port access.

ACCESS CONTROL
LISTS
ACLs provide packet filtering for IP frames (based on address, protocol,
TCP/UDP port number or TCP control code) or any frames (based on MAC
address or Ethernet type). ACLs can by used to improve performance by
blocking unnecessary network traffic or to implement security controls by
restricting access to specific network resources or protocols.
PORT CONFIGURATION You can manually configure the speed and duplex mode, and flow control
used on specific ports, or use auto-negotiation to detect the connection
settings used by the attached device. Use the full-duplex mode on ports
whenever possible to double the throughput of switch connections. Flow
control should also be enabled to control network traffic during periods of
congestion and prevent the loss of packets when port buffer thresholds are
exceeded. The switch supports flow control based on the IEEE 802.3x
standard (now incorporated in IEEE 802.3-2002).
PORT MIRRORING The switch can unobtrusively mirror traffic from any port to a monitor port.
You can then attach a protocol analyzer or RMON probe to this port to
perform traffic analysis and verify connection integrity.
PORT TRUNKING Ports can be combined into an aggregate connection. Trunks can be
manually set up or dynamically configured using Link Aggregation Control
Protocol (LACP – IEEE 802.3-2005). The additional ports dramatically
increase the throughput across any connection, and provide redundancy by
taking over the load if a port in the trunk should fail. The switch supports
up to 12 trunks.
RATE LIMITING This feature controls the maximum rate for traffic transmitted or received
on an interface. Rate limiting is configured on interfaces at the edge of a
network to limit traffic into or out of the network. Traffic that falls within
the rate limit is transmitted, while packets that exceed the acceptable
amount of traffic are dropped.
STORM CONTROL Broadcast, multicast and unknown unicast storm suppression prevents
traffic from overwhelming the network.When enabled on a port, the level of
broadcast traffic passing through the port is restricted. If broadcast traffic
rises above a pre-defined threshold, it will be throttled until the level falls
back beneath the threshold.
STATIC ADDRESSES A static address can be assigned to a specific interface on this switch.
Static addresses are bound to the assigned interface and will not be
moved. When a static address is seen on another interface, the address will
be ignored and will not be written to the address table. Static addresses
can be used to provide network security by restricting access for a known
host to a specific port.

| Introduction
IEEE 802.1D BRIDGE The switch supports IEEE 802.1D transparent bridging. The address table
facilitates data switching by learning addresses, and then filtering or
forwarding traffic based on this information. The address table supports up
to 8K addresses.
STORE-AND-FORWARD
SWITCHING
SPANNING TREE
ALGORITHM
The switch copies each frame into its memory before forwarding them to
another port. This ensures that all frames are a standard Ethernet size and
have been verified for accuracy with the cyclic redundancy check (CRC).
This prevents bad frames from entering the network and wasting
bandwidth.
To avoid dropping frames on congested ports, the switch provides 4 Mbits
for frame buffering. This buffer can queue packets awaiting transmission
on congested networks.
The switch supports these spanning tree protocols:
◆ Spanning Tree Protocol (STP, IEEE 802.1D) – This protocol provides
loop detection. When there are multiple physical paths between
segments, this protocol will choose a single path and disable all others
to ensure that only one route exists between any two stations on the
network. This prevents the creation of network loops. However, if the
chosen path should fail for any reason, an alternate path will be
activated to maintain the connection.
◆ Rapid Spanning Tree Protocol (RSTP, IEEE 802.1w) – This protocol
reduces the convergence time for network topology changes to about 3
to 5 seconds, compared to 30 seconds or more for the older IEEE
802.1D STP standard. It is intended as a complete replacement for STP,
but can still interoperate with switches running the older standard by
automatically reconfiguring ports to STP-compliant mode if they detect
STP protocol messages from attached devices.
◆ Multiple Spanning Tree Protocol (MSTP, IEEE 802.1s) – This protocol is
a direct extension of RSTP. It can provide an independent spanning tree
for different VLANs. It simplifies network management, provides for
even faster convergence than RSTP by limiting the size of each region,
and prevents VLAN members from being segmented from the rest of
the group (as sometimes occurs with IEEE 802.1D STP).

| Introduction
VIRTUAL LANS The switch supports up to 255 VLANs. A Virtual LAN is a collection of
network nodes that share the same collision domain regardless of their
physical location or connection point in the network. The switch supports
tagged VLANs based on the IEEE 802.1Q standard. Members of VLAN
groups can be dynamically learned via GVRP, or ports can be manually
assigned to a specific set of VLANs. This allows the switch to restrict traffic
to the VLAN groups to which a user has been assigned. By segmenting
your network into VLANs, you can:
◆ Eliminate broadcast storms which severely degrade performance in a
flat network.
◆ Simplify network management for node changes/moves by remotely
configuring VLAN membership for any port, rather than having to
manually change the network connection.
◆ Provide data security by restricting all traffic to the originating VLAN,
except where a connection is explicitly defined via the switch's routing
service.
IEEE 802.1Q
TUNNELING (QINQ)
TRAFFIC
PRIORITIZATION
◆ Use private VLANs to restrict traffic to pass only between data ports
and the uplink ports, thereby isolating adjacent ports within the same
VLAN, and allowing you to limit the total number of VLANs that need to
be configured.
◆ Use protocol VLANs to restrict traffic to specified interfaces based on
protocol type.
This feature is designed for service providers carrying traffic for multiple
customers across their networks. QinQ tunneling is used to maintain
customer-specific VLAN and Layer 2 protocol configurations even when
different customers use the same internal VLAN IDs. This is accomplished
by inserting Service Provider VLAN (SPVLAN) tags into the customer’s
frames when they enter the service provider’s network, and then stripping
the tags when the frames leave the network.
This switch prioritizes each packet based on the required level of service,
using four priority queues with strict priority, Weighted Round Robin
(WRR), Deficit Round-Robin (DRR) scheduling, or a combination of strict
and weighted queuing. It uses IEEE 802.1p and 802.1Q tags to prioritize
incoming traffic based on input from the end-station application. These
functions can
data and best-effort data.
be used to provide independent priorities for delay-sensitive
This switch also supports several common methods of prioritizing layer 3/4
traffic to meet application requirements. Traffic can be prioritized based on
the priority bits in the IP frame’s Type of Service (ToS) octet using DSCP, or
IP Precedence. When these services are enabled, the priorities are mapped
to a Class of Service value by the switch, and the traffic then sent to the
corresponding output queue.

| Introduction
QUALITYOF SERVICE Differentiated Services (DiffServ) provides policy-based management
mechanisms used for prioritizing network resources to meet the
requirements of specific traffic types on a per-hop basis. Each packet is
classified upon entry into the network based on access lists, IP Precedence
or DSCP values, or VLAN lists. Using access lists allows you select traffic
based on Layer 2, Layer 3, or Layer 4 information contained in each
packet. Based on network policies, different kinds of traffic can be marked
for different kinds of forwarding.
MULTICAST FILTERING Specific multicast traffic can be assigned to its own VLAN to ensure that it
does not interfere with normal network traffic and to guarantee real-time
delivery by setting the required priority level for the designated VLAN. The
switch uses IGMP Snooping and Query to manage multicast group
registration.
SYSTEM DEFAULTS
The switch’s system defaults are provided in the configuration file
“Factory_Default_Config.cfg.” To reset the switch defaults, this file should

BASIC CONFIGURATION
CONSOLE
CONNECTION
The CLI program provides two different command levels — normal access
level (Normal Exec) and privileged access level (Privileged Exec). The
commands available at the Normal Exec level are a limited subset of those
available at the Privileged Exec level and allow you to only display
information and use basic utilities. To fully configure the switch
parameters, you must access the CLI at the Privileged Exec level.
Access to both CLI levels are controlled by user names and passwords. The
switch has a default user name and password for each level. To log into the
CLI at the Privileged Exec level using the default user name and password,
perform these steps:
1. To initiate your console connection, press <Enter>. The “User Access
Verification” procedure starts.
2. At the User Name prompt, enter “admin.”
3. At the Password prompt, also enter “admin.” (The password characters
are not displayed on the console screen.)
4. The session is opened and the CLI displays the “Console#” prompt
indicating you have access at the Privileged Exec level.
SETTING PASSWORDS If this is your first time to log into the CLI program, you should define new
passwords for both default user names using the "username" command,
record them and put them in a safe place.
Passwords can consist of up to 32 alphanumeric characters and are case
sensitive. To prevent unauthorized access to the switch, set the passwords
as follows:
1. Open the console interface with the default user name and password
“admin” to access the Privileged Exec level.
2. Type “configure” and press <Enter>.
3. Type “username guest password 0 password,” for the Normal Exec
level, where password is your new password. Press <Enter>.
4. Type “username admin password 0 password,” for the Privileged Exec
level, where password is your new password. Press <Enter>.
Username: admin
Password:
CLI session with the MS453490M is opened.
To end the CLI session, enter [Exit].
You must establish IP address information for the switch to obtain
management access through the network. This can be done in either of the
following ways:
◆ Manual — You have to input the information, including IP address and
subnet mask. If your management station is not in the same IP subnet
as the switch, you will also need to specify the default gateway router.
◆ Dynamic — The switch can send IPv4 configuration requests to BOOTP
or DHCP address allocation servers on the network, or can
automatically generate a unique IPv6 host address based on the local
subnet address prefix received in router advertisement messages.
MANUAL CONFIGURATION
You can manually assign an IP address to the switch. You may also need to
specify a default gateway that resides between this device and
management stations that exist on another network segment. Valid IPv4
addresses consist of four decimal numbers, 0 to 255, separated by periods.
Anything outside this format will not be accepted by the CLI program.
N
OTE
:
The IP address for this switch is obtained via DHCP by default.
ASSIGNINGAN IPV4 ADDRESS
Before you can assign an IP address to the switch, you must obtain the
following information from your network administrator:
◆ IP address for the switch
◆ Network mask for this network
◆ Default gateway for the network
To assign an IPv4 address to the switch, complete the following steps
1. From the Global Configuration mode prompt, type “interface vlan 1” to
access the interface-configuration mode. Press <Enter>.
2. Type “ip address ip-address netmask,” where “ip-address” is the switch
IP address and “netmask” is the network mask for the network. Press
<Enter>.
3. Type “exit” to return to the global configuration mode prompt. Press
<Enter>.

4. To set the IP address of the default gateway for the network to which
the switch belongs, type “ip default-gateway gateway,” where
“gateway” is the IP address of the default gateway. Press <Enter>.
This section describes how to configure a “link local” address for
connectivity within the local subnet only, and also how to configure a
“global unicast” address, including a network prefix for use on a multisegment network and the host portion of the address.
An IPv6 prefix or address must be formatted according to RFC 2373 “IPv6
Addressing Architecture,” using 8 colon-separated 16-bit hexadecimal
values. One double colon may be used to indicate the appropriate number
of zeros required to fill the undefined fields. For detailed information on the
other ways to assign IPv6 addresses, see "Setting the Switch’s IP Address
(IP Version 6)" on page 415.
Link Local Address — All link-local addresses must be configured with a
prefix of FE80. Remember that this address type makes the switch
accessible over IPv6 for all devices attached to the same local subnet only.
Also, if the switch detects that the address you configured conflicts with
that in use by another device on the subnet, it will stop using the address
in question, and automatically generate a link local address that does not
conflict with any other devices on the local subnet.
To configure an IPv6 link local address for the switch, complete the
following steps:
1. From the Global Configuration mode prompt, type “interface vlan 1” to
access the interface-configuration mode. Press <Enter>.
2. Type “ipv6 address” followed by up to 8 colon-separated 16-bit
hexadecimal values for the ipv6-address similar to that shown in the
example, followed by the “link-local” command parameter. Then press
<Enter>.

Address for Multi-segment Network — Before you can assign an IPv6
address to the switch that will be used to connect to a multi-segment
network, you must obtain the following information from your network
administrator:
◆ Prefix for this network
◆ IP address for the switch
◆ Default gateway for the network
For networks that encompass several different subnets, you must define
the full address, including a network prefix and the host address for the
switch. You can specify either the full IPv6 address, or the IPv6 address
and prefix length. The prefix length for an IPv6 network is the number of
bits (from the left) of the prefix that form the network address, and is
expressed as a decimal number. For example, all IPv6 addresses that start
with the first byte of 73 (hexadecimal) could be expressed as
73:0:0:0:0:0:0:0/8 or 73::/8.
To generate an IPv6 global unicast address for the switch, complete the
following steps:
1. From the global configuration mode prompt, type “interface vlan 1” to
access the interface-configuration mode. Press <Enter>.
2. From the interface prompt, type “ipv6 address ipv6-address” or
“ipv6 address ipv6-address/prefix-length,” where “prefix-length”
indicates the address bits used to form the network portion of the
address. (The network address starts from the left of the prefix and
should encompass some of the ipv6-address bits.) The remaining bits
are assigned to the host interface. Press <Enter>.
3. Type “exit” to return to the global configuration mode prompt. Press
<Enter>.
4. To set the IP address of the IPv6 default gateway for the network to
which the switch belongs, type “ipv6 default-gateway gateway,” where
“gateway” is the IPv6 address of the default gateway. Press <Enter>.

If you select the “bootp” or “dhcp” option, the system will immediately
start broadcasting service requests. IP will be enabled but will not function
until a BOOTP or DHCP reply has been received. Requests are broadcast
every few minutes using exponential backoff until IP configuration
information is obtained from a BOOTP or DHCP server. BOOTP and DHCP
values can include the IP address, subnet mask, and default gateway. If
the DHCP/BOOTP server is slow to respond, you may need to use the “ip
dhcp restart client” command to re-start broadcasting service requests.
Note that the “ip dhcp restart client” command can also be used to start
broadcasting service requests for all VLANs configured to obtain address
assignments through BOOTP or DHCP. It may be necessary to use this
command when DHCP is configured on a VLAN, and the member ports
which were previously shut down are now enabled.
If the “bootp” or “dhcp” option is saved to the startup-config file (step 6),
then the switch will start broadcasting service requests as soon as it is
powered on.
To automatically configure the switch by communicating with BOOTP or
DHCP address allocation servers on the network, complete the following
steps:
1. From the Global Configuration mode prompt, type “interface vlan 1” to
access the interface-configuration mode. Press <Enter>.
2. At the interface-configuration mode prompt, use one of the following
commands:
■
To obtain IP settings via DHCP, type “ip address dhcp” and press
<Enter>.
■
To obtain IP settings via BOOTP, type “ip address bootp” and press
<Enter>.
3. Type “end” to return to the Privileged Exec mode. Press <Enter>.

OBTAININGAN IPV6 ADDRESS
Link Local Address — There are several ways to configure IPv6 addresses.
The simplest method is to automatically generate a “link local” address
(identified by an address prefix of FE80). This address type makes the
switch accessible over IPv6 for all devices attached to the same local
subnet.
To generate an IPv6 link local address for the switch, complete the
following steps:
1. From the Global Configuration mode prompt, type “interface vlan 1” to
access the interface-configuration mode. Press <Enter>.

ENABLING SNMP
MANAGEMENT ACCESS
Console#
The switch can be configured to accept management commands from
Simple Network Management Protocol (SNMP) applications. You can
configure the switch to respond to SNMP requests or generate SNMP traps.
When SNMP management stations send requests to the switch (either to
return information or to set a parameter), the switch provides the
requested data or sets the specified parameter. The switch can also be
configured to send information to SNMP managers (without being
requested by the managers) through trap messages, which inform the
manager that certain events have occurred.
The switch includes an SNMP agent that supports SNMP version 1, 2c, and
3 clients. To provide management access for version 1 or 2c clients, you
must specify a community string. The switch provides a default MIB View
(i.e., an SNMPv3 construct) for the default “public” community string that
provides read access to the entire MIB tree, and a default view for the
“private” community string that provides read/write access to the entire
MIB tree. However, you may assign new views to version 1 or 2c
community strings that suit your specific security requirements (see
"Setting SNMPv3 Views" on page 375).
– 66 –
C
HAPTER

| Initial Switch Configuration
Basic Configuration
COMMUNITY STRINGS (FOR SNMP VERSION 1 AND 2CCLIENTS)
Community strings are used to control management access to SNMP
version 1 and 2c stations, as well as to authorize SNMP stations to receive
trap messages from the switch. You therefore need to assign community
strings to specified users, and set the access level.
The default strings are:
◆ public - with read-only access. Authorized management stations are
only able to retrieve MIB objects.
◆ private - with read/write access. Authorized management stations are
able to both retrieve and modify MIB objects.
To prevent unauthorized access to the switch from SNMP version 1 or 2c
clients, it is recommended that you change the default community strings.
To configure a community string, complete the following steps:
1. From the Privileged Exec level global configuration mode prompt, type
“snmp-server community string mode,” where “string” is the
community access string and “mode” is rw (read/write) or ro (read
only). Press <Enter>. (Note that the default mode is read only.)
2. To remove an existing string, simply type “no snmp-server community
string,” where “string” is the community access string to remove. Press
<Enter>.
Console(config)#snmp-server community admin rw
Console(config)#snmp-server community private
Console(config)#
N
OTE
:
If you do not intend to support access to SNMP version 1 and 2c
clients, we recommend that you delete both of the default community
strings. If there are no community strings, then SNMP management access
from SNMP v1 and v2c clients is disabled.
TRAP RECEIVERS
You can also specify SNMP stations that are to receive traps from the
switch. To configure a trap receiver, use the “snmp-server host” command.
From the Privileged Exec level global configuration mode prompt, type:
“snmp-server host host-address community-string
[version {1 | 2c | 3 {auth | noauth | priv}}]”
where “host-address” is the IP address for the trap receiver, “communitystring” specifies access rights for a version 1/2c host, or is the user name
of a version 3 host, “version” indicates the SNMP client version, and “auth |
noauth | priv” means that authentication, no authentication, or

authentication and privacy is used for v3 clients. Then press <Enter>. For
a more detailed description of these parameters, see "snmp-server host"
on page 560. The following example creates a trap host for each type of
SNMP client.
Console(config)#snmp-server host 10.1.19.23 batman

Console(config)#snmp-server host 10.1.19.34 barbie version 3 auth
Console(config)#
CONFIGURING ACCESSFOR SNMP VERSION 3 CLIENTS
To configure management access for SNMPv3 clients, you need to first
create a view that defines the portions of MIB that the client can read or
write, assign the view to a group, and then assign the user to a group. The
following example creates one view called “mib-2” that includes the entire
MIB-2 tree branch, and then another view that includes the IEEE 802.1d
bridge MIB. It assigns these respective read and read/write views to a
group call “r&d” and specifies group authentication via MD5 or SHA. In the
last step, it assigns a v3 user to this group, indicating that MD5 will be
used for authentication, provides the password “greenpeace” for
authentication, and the password “einstien” for encryption.
Console(config)#snmp-server view mib-2 1.3.6.1.2.1 included
Console(config)#snmp-server view 802.1d 1.3.6.1.2.1.17 included

For a more detailed explanation on how to configure the switch for access
from SNMP v3 clients, refer to "Simple Network Management Protocol" on
page 369, or refer to the specific CLI commands for SNMP starting on
page 555.
MANAGING SYSTEM FILES
The switch’s flash memory supports three types of system files that can be
managed by the CLI program, web interface, or SNMP. The switch’s file
system allows files to be uploaded and downloaded, copied, deleted, and
set as a start-up file.
The types of files are:
◆ Configuration — This file type stores system configuration information
and is created when configuration settings are saved. Saved
configuration files can be selected as a system start-up file or can be
uploaded via FTP/TFTP to a server for backup. The file named
“Factory_Default_Config.cfg” contains all the system default settings
and cannot be deleted from the system. If the system is booted with
the factory default settings, the switch will also create a file named
– 68 –
C
HAPTER
“startup1.cfg” that contains system settings for switch initialization,
including information about the unit identifier, and MAC address for the
switch. The configuration settings from the factory defaults
configuration file are copied to this file, which is then used to boot the
switch. See "Saving or Restoring Configuration Settings" on page 69 for
more information.
◆ Operation Code — System software that is executed after boot-up,
also known as run-time code. This code runs the switch operations and
provides the CLI and web management interfaces. See "Managing
System Files" on page 94 for more information.
◆ Diagnostic Code — Software that is run during system boot-up, also
known as POST (Power On Self-Test).
Due to the size limit of the flash memory, the switch supports only two
operation code files. However, you can have as many diagnostic code files
and configuration files as available flash memory space allows. The switch
has a total of 32 Mbytes of flash memory for system files.
In the system flash memory, one file of each type must be set as the startup file. During a system boot, the diagnostic and operation code files set as
the start-up file are run, and then the start-up configuration file is loaded.

SAVINGOR
RESTORING
CONFIGURATION
SETTINGS
Note that configuration files should be downloaded using a file name that
reflects the contents or usage of the file settings. If you download directly
to the running-config, the system will reboot, and the settings will have to
be copied from the running-config to a permanent file.
Configuration commands only modify the running configuration file and are
not saved when the switch is rebooted. To save all your configuration
changes in nonvolatile storage, you must copy the running configuration
file to the start-up configuration file using the “copy” command.
New startup configuration files must have a name specified. File names on
the switch are case-sensitive, can be from 1 to 31 characters, must not
contain slashes (\ or /), and the leading letter of the file name must not be
a period (.). (Valid characters: A-Z, a-z, 0-9, “.”, “-”, “_”)
There can be more than one user-defined configuration file saved in the
switch’s flash memory, but only one is designated as the “startup” file that
is loaded when the switch boots. The copy running-config startup-config command always sets the new file as the startup file. To select a
previously saved configuration file, use the boot system config:<filename> command.
The maximum number of saved configuration files depends on available
flash memory. The amount of available flash memory can be checked by
using the dir command.

CONFIGURING SUPPORTFOR JUMBO FRAMES
Use the System > Capability page to configure support for jumbo frames.
The switch provides more efficient throughput for large sequential data
transfers by supporting jumbo frames up to 9216 bytes for Gigabit
Ethernet. Compared to standard Ethernet frames that run only up to
1.5 KB, using jumbo frames significantly reduces the per-packet overhead
required to process protocol encapsulation fields.
CLI REFERENCES
◆ "System Management Commands" on page 493
USAGE GUIDELINES
To use jumbo frames, both the source and destination end nodes (such as
a computer or server) must support this feature. Also, when the connection
is operating at full duplex, all switches in the network between the two end
nodes must be able to accept the extended frame size. And for half-duplex
connections, all devices in the collision domain would need to support
jumbo frames.

If you replaced a file currently used for startup and want to start using the
new file, reboot the system via the System > Reset menu.
Use the System > File (Copy) page to save the current configuration
settings to a local file on the switch. The configuration settings are not
automatically saved by the system for subsequent use when the switch is
rebooted. You must save these settings to the current startup file, or to
another file which can be subsequently set as the startup file.

OPERATION CODE
UPGRADE
Use the System > File (Automatic Operation Code Upgrade) page to
automatically download an operation code file when a file newer than the
currently installed one is discovered on the file server. After the file is
transferred from the server and successfully written to the file system, it is
automatically set as the startup file, and the switch is rebooted.

USAGE GUIDELINES
◆ If this feature is enabled, the switch searches the defined URL once
during the bootup sequence.
◆ FTP (port 21) and TFTP (port 69) are both supported. Note that the
TCP/UDP port bindings cannot be modified to support servers listening
on non-standard ports.
◆ The host portion of the upgrade file location URL must be a valid IPv4
IP address. DNS host names are not recognized. Valid IP addresses
consist of four numbers, 0 to 255, separated by periods.
◆ The path to the directory must also be defined. If the file is stored in
the root directory for the FTP/TFTP service, then use the “/” to indicate
this (e.g., ftp://192.168.0.1/).
◆ The file name must not be included in the upgrade file location URL.
The file name of the code stored on the remote server must be
ms453490m.bix (using upper case and lower case letters exactly as
indicated here). Enter the file name for other switches described in this
manual exactly as shown on the web interface.
◆ The FTP connection is made with PASV mode enabled. PASV mode is
needed to traverse some fire walls, even if FTP traffic is not blocked.
PASV mode cannot be disabled.
◆ The switch-based search function is case-insensitive in that it will
accept a file name in upper or lower case (i.e., the switch will accept
MS453490M.BIX from the server even though MS453490M.bix was

requested). However, keep in mind that the file systems of many
operating systems such as Unix and most Unix-like systems (FreeBSD,
NetBSD, OpenBSD, and most Linux distributions, etc.) are casesensitive, meaning that two files in the same directory, ms453490m.bix
and MS453490M.bix are considered to be unique files. Thus, if the
upgrade file is stored as MS453490M.bix (or even Ms453490m.bix) on
a case-sensitive server, then the switch (requesting ms453490m.bix)
will not be upgraded because the server does not recognize the
requested file name and the stored file name as being equal. A notable
exception in the list of case-sensitive Unix-like operating systems is
Mac OS X, which by default is case-insensitive. Please check the
documentation for your server’s operating system if you are unsure of
its file system’s behavior.
◆ Note that the switch itself does not distinguish between upper and
lower-case file names, and only checks to see if the file stored on the
server is more recent than the current runtime image.
◆ If two operation code image files are already stored on the switch’s file
system, then the non-startup image is deleted before the upgrade
image is transferred.
◆ The automatic upgrade process will take place in the background
without impeding normal operations (data switching, etc.) of the
switch.
◆ During the automatic search and transfer process, the administrator
cannot transfer or update another operation code image, configuration
file, public key, or HTTPS certificate (i.e., no other concurrent file
management operations are possible).
◆ The upgrade operation code image is set as the startup image after it
has been successfully written to the file system.
◆ The switch will send an SNMP trap and make a log entry upon all
upgrade successes and failures.
◆ The switch will immediately restart after the upgrade file is successfully
written to the file system and set as the startup image.
PARAMETERS
The following parameters are displayed:
◆ Automatic Opcode Upgrade – Enables the switch to search for an
upgraded operation code file during the switch bootup process.
(Default: Disabled)
◆ Automatic Upgrade Location URL – Defines where the switch should
search for the operation code upgrade file. The last character of this
URL must be a forward slash (“/”). The ms453490m.bix filename must
not be included since it is automatically appended by the switch.
