Introduction
The 1Gb Intelligent L2 Switch provides two switch modes: The conventional L2 switch mode, and SmartPanel
mode. The switch can store up to two different software image, called image1 and image2. Normally, the
conventional L2 switch software image is stored in image1, and the SmartPanel software is stored in image2. You
can select which software image (image1 or image2) you want to run in switch memory. By default, the switch
software is loaded from image1. To run the SmartPanel software, you need to change a software image to image2
and reboot the switch. See additional references for configuration to select a software image.
This guide explains how to configure the switch in running the SmartPanel software. The SmartPanel provides a
simple Ethernet interface option for connecting to the network infrastructure. The number and type of configuration
options on the SmartPanel are restricted to reduce the initial setup complexity and to minimize the impact on
upstream networking devices.

Additional information about installing and configuring the switch is available in the following guides, which are
attached in this product.

Management Network
The 1Gb Intelligent L2 Switch is a Switch Module within the Blade Enclosure. The Blade Enclosure includes an
Enclosure Manager Card which manages the modules and CPU Blades in the enclosure.
The 1Gb Intelligent L2 Switch communicates with the Enclosure Manager Card through its internal management
port (port 19). The factory default settings permit management and control access to the switch through the 10/100
Mbps Ethernet port on the Blade Enclosure, or the built-in console port.
The switch management network has the following characteristics:
Port 19 — Management port 19 has the following configuration:
Flow control: both
Auto-negotiation
Untagged
Port VLAN ID (PVID): 4095
VLAN 4095 — Management VLAN 4095 isolates management traffic within the switch. VLAN 4095 contains
only one member port (port 19). No other ports can be members of VLAN 4095.
Interface 256 — Management interface 256 is associated with VLAN 4095. No other interfaces can be
associated with VLAN 4095. The IP address of the management interface is assigned through Dynamic Host
Control Protocol (DHCP).
Gateway 4 — This gateway is the default gateway for the management interface.
Connecting to the switch
You can access the command line interface in one of the following ways:
Using a console connection via the console port
Using a Telnet connection over the network
Using a Secure Shell (SSH) connection to securely log in over a network
Using a HTTP connection over the network
Establishing a console connection
To establish a console connection with the switch, you need:
A null modem cable with a female DB-9 connector (See the User’s Guide for more information.)
An ASCII terminal or a computer running terminal emulation software set to the parameters shown in the table
below
To establish a console connection with the switch:
1. Connect the terminal to the console port using the null modem cable.
2. Power on the terminal.
3. Press the Enter key a few times on the terminal to establish the connection.
4. You will be required to enter a password for access to the switch. (For more information, see the “Accessing
the switch” section later in this chapter.)
N8406-022A 1Gb Intelligent L2 Switch Smart Panel Reference Guide 6
Setting an IP address
NOTE: You can assign the IP address only on the management port 19.
telnet <1Gb Intelligent L2 Switch IP address>
NOTE: It is recommended that you change default switch passwords after initial configuration and as
regularly as required under your network security policies. For more information, see the “Setting passwords”
section in the “First-time configuration” chapter.
To access the switch via a Telnet, an SSH connection, or an HTTP connection, you need to have an Internet
Protocol (IP) address set for the switch. You can assign the IP address only to the management interface (interface
256), associated with port 19. The management interface requests its IP address from a Dynamic Host Control
Protocol (DHCP) server on the Enclosure Manager Card. See the User’s Guide of the Enclosure Manager Card for
configuration to assign the IP address to the switch modules.
Establishing a Telnet connection
A Telnet connection offers the convenience of accessing the switch from any workstation connected to the network.
Telnet provides the same options for user, operator, and administrator access as those available through the
console port. By default, Telnet is enabled on the switch. The switch supports four concurrent Telnet connections.
Once the IP parameters are configured, you can access the CLI using a Telnet connection. To establish a Telnet
connection with the switch, run the Telnet program on the workstation and enter the telnet command, followed by
the switch IP address:
You will then be prompted to enter a password. The password entered determines the access level: administrator,
operator, or user. See the “Accessing the switch” section later in this chapter for description of default passwords.
Establishing an SSH connection
Although a remote network administrator can manage the configuration of a switch via Telnet, this method does not
provide a secure connection. The Secure Shell (SSH) protocol enables you to securely log into the switch over the
network.
As a secure alternative to using Telnet to manage switch configuration, SSH ensures that all data sent over the
network is encrypted and secure. In order to use SSH, you must first configure it on the switch. See the “Secure
Shell Server configuration” section in the “Configuration Menu” chapter for information on how to configure SSH.
Establishing an HTTP connection
By default, HTTP is enabled on the switch. You can configure the switch using the Web browser. For more
information, see the “Browser-based interface” chapter.
Accessing the switch
To enable better switch management and user accountability, the switch provides different levels or classes of user
access. Levels of access to the CLI and Web management functions and screens increase as needed to perform
various switch management tasks. The three levels of access are:
User—User interaction with the switch is completely passive; nothing can be changed on the switch. Users
may display information that has no security or privacy implications, such as switch statistics and current
operational state information.
Operator—Operators can only effect temporary changes on the switch. These changes will be lost when the
switch is rebooted/reset. Operators have access to the switch management features used for daily switch
operations. Because any changes an operator makes are undone by a reset of the switch, operators cannot
severely impact switch operation, but do have access to the Maintenance menu.
Administrator—Only administrators can make permanent changes to the switch configuration, changes that
are persistent across a reboot/reset of the switch. Administrators can access switch functions to configure and
troubleshoot problems on the switch. Because administrators can also make temporary (operator-level)
changes as well, they must be aware of the interactions between temporary and permanent changes.
Access to switch functions is controlled through the use of unique usernames and passwords. Once you are
connected to the switch via the local console, Telnet, or SSH, you are prompted to enter a password. The
password entered determines the access level. The default user names/password for each access level is listed in
the following table. Once you are connected to the switch via HTTP, you are prompted to enter a user account and
password.
N8406-022A 1Gb Intelligent L2 Switch Smart Panel Reference Guide 7
Table 3 User access levels
User account
Description and tasks performed
user
The user has no direct responsibility for switch management. He or she can view all
switch status information and statistics, but cannot make any configuration changes to
the switch. The user account is enabled by default, and the default password is user.
oper
The operator manages all functions of the switch. The operator can reset ports or the
entire switch. By default, the operator account is disabled and has no password.

Port Group Mapping
NOTE: Cross-connect ports (17-18) are not available in the SmartPanel.
SmartPanel ports can be combined into Port Groups. Up to five Port Groups are available in the SmartPanel. A
Spare Ports Group is available for unused ports.
VLANs and Link Aggregation Groups (trunks) are configured automatically for each Port Group. No network loops
are allowed in the configuration. All external ports in the Port Group form a trunk group (static trunk or Link
Aggregation Group).
Port Group Characteristics
SmartPanel Port Groups must have the following characteristics.
Each Port Group must contain at least one external port (20-24) and one internal server blade port (1-16).
All external ports in a Port Group must have the same configuration.
Each port in the Port Group is a member of a unique, untagged VLAN.
Tagged VLANs (1-4094) can be assigned to each Port Group. Tagged VLANs cannot be configured across
multiple Port Groups.
All external ports in the Port Group form a trunk group.
Port Group configuration
On the BBI, choose Port Group Mapping to select the Port Group for each of the external ports and server blade
ports. Click Apply to make the changes active. Click Save to write the configuration to flash memory.
N8406-022A 1Gb Intelligent L2 Switch Smart Panel Reference Guide 13

N8406-022A 1Gb Intelligent L2 Switch Smart Panel Reference Guide 15
NOTE: Spare Ports Group for unused ports is assigned a PVID.
NOTE: The SmartPanel does not permit configuration of tagged VLANs across multiple Ports Groups.
VLAN
Virtual LANs (VLANs) are commonly used to split up groups of network users into manageable broadcast domains,
to create logical segmentation of workgroups, and to enforce security policies among logical segments. This switch
supports up to 1,000 VLANs per switch. Even though the maximum number of VLANs supported at any given time
is 1,000, each can be identified with any number between 1 and 4095. VLAN 4095 is used by the management
network, which includes the management port 19. VLAN 4095 configuration cannot be modified.
PVID
Each Port Group has a configurable default VLAN number, known as its PVID (Port VLAN ID). All ports are set as
untagged members of PVID. By default, all ports except port 19 are configured as Group1. The PVID of Group1 is 1.
The unique value of PVID is assigned to the Port Group, which contains at least one external port and one internal
server blade port. For the configuration, see the “Port VLAN ID configuration” section later in this chapter.
802.1Q VLAN Tagging
802.1Q VLAN tagging provides standards-based VLAN support for Ethernet systems. This standard permits
multiple VLANs to be transmitted over a single Ethernet connection.
Tagging places the VLAN identifier in the frame header of a packet, allowing each port to belong to multiple VLANs.
For the configuration to add the VLAN ID to the Port Group, see the “Non-Default Virtual LANs” section later in this
chapter.
Port VLAN ID configuration
Assign at lease one external port and one internal blade server port to the Port Group to use it and assign a unique
value of PVID. On the BBI, choose System settings > Uplink/Group to change the PVID. Edit the value of the
following Port VLAN ID. The value of unused Port Group is 0.

NOTE: Because all ports in a Port Group belong to the same trunk group, individual external ports cannot be
used as a regular 802.3 link. Do not plug a workstation directly into one of the SmartPanel’s external ports,
unless that is the only device plugged into the ports.
Trunking
Trunk groups provide super-bandwidth, multi-link connections between SmartPanel or other trunk-capable devices.
A trunk group is a group of ports that act together, combining their bandwidth to create a single, larger virtual link.
SmartPanel trunk groups are static link aggregation groups that are compatible with Cisco’s EtherChannel
technology.
The SmartPanel is statically configured to place each Port Group into a separate trunk group.
When using port trunk groups between the SmartPanel and a switch, you can create a virtual link, operating at up
to 5 Gigabits per second, depending on how many physical ports are combined.
Statistical Load Distribution
Network traffic is statistically distributed between ports in a trunk group. The SmartPanel uses the source and
destination IP address information present in each transmitted IP frame to determine load distribution. If the frame
is not an IP frame, then Layer 2 MAC addresses are used.
Each packet’s particular combination of source and destination addresses results in selecting one line in the trunk
group for data transmission. If there are enough devices feeding the trunk lines, then traffic distribution becomes
relatively even.
Built-In Fault Tolerance
Since trunk groups are comprised of multiple physical links, each trunk group is inherently fault tolerant. As long as
one connection is available, the trunk remains active.
Statistical load balancing is maintained whenever a port in a trunk group is lost or returned to service.
Trunk group configuration rules
The trunking feature operates according to specific configuration rules. When working with trunks, consider the
following rules that determine how a trunk group reacts in any network topology.
All trunks must originate from one device, and lead to one destination device.
Trunking from third-party devices must comply with Cisco® EtherChannel® technology.
All external ports in a Port Group must have the same configuration.
Only external ports in a Port Group are trunked. For Port Group configuration, see the “Port Group
configuration”.
Link Aggregation Control Protocol
Link Aggregation Control Protocol (LACP) is an IEEE 802.3ad standard for grouping several physical ports into one
logical port (known as a dynamic trunk group or Link Aggregation Group) with any device that supports the
standard. Please refer to IEEE 802.3ad-2002 for a full description of the standard.
The 802.3ad standard allows standard Ethernet links to form a single Layer 2 link using the Link Aggregation
Control Protocol (LACP). Link aggregation is a method of grouping physical link segments of the same media type
and speed in full duplex, and treating them as if they were part of a single, logical link segment. If a link in a LACP
trunk group fails, traffic is reassigned dynamically to the remaining link/s of the dynamic trunk group.
N8406-022A 1Gb Intelligent L2 Switch Smart Panel Reference Guide 22
Trunk Group configuration
On the BBI, choose System Settings > Uplink/Group to enable or disable the Link Aggregation Control Protocol.
When enabled, the external ports are configured as a LACP trunk group. When disabled, they are configured as a
static trunk group. The default is disabled.
Failover
The primary application for Failover is to support Network Adapter Teaming. With Network Adapter Teaming, the
NICs on each server all share the same IP address, and are configured into a team. One NIC is the primary link,
and the other is a standby link.
Failover is enabled by default. You can enable or disable Failover on a Port Group. When enabled, Failover works
as follows.
If some (or all) of the links fail in the failover trigger, the SmartPanel disables all internal ports of the Port
Group. When the internal ports are disabled, it causes the NIC team on the affected server blade to failover
from the primary to the backup NIC. This process is called a failover event.
When the appropriate links return to service, the SmartPanel enables the internal ports of the Port Group.
This causes the NIC team on the affected server blades to fail back to the primary SmartPanel (unless AutoFallback is disabled on the NIC team). The backup processes traffic until the primary’s internal links come up,
which takes up to five seconds.
The failover limit lets you specify the minimum number of operational links required within the failover trigger before
the trigger initiates a failover event. For example, if the limit is four, a failover event occurs when the number of
operational links in the trigger is four or fewer. When you set the limit to all, the SmartPanel triggers a failover event
only when no links in the trigger are operational. The default is all.
N8406-022A 1Gb Intelligent L2 Switch Smart Panel Reference Guide 23
Failover configuration
On the BBI, choose System Settings > Uplink/Group to configure the Switch Failover and Number of Links to
Trigger Failover.
IGMP Snooping
IGMP Snooping allows the SmartPanel to forward multicast traffic only to those ports that request it. IGMP
Snooping prevents multicast traffic from being flooded to all ports. The SmartPanel learns which server hosts are
interested in receiving multicast traffic, and forwards it only to ports connected to those servers.
On the BBI, choose System Settings > IGMP Snooping to enable IGMP Snooping. The default is disabled.

Introduction
The CLI is used for viewing switch information and statistics. In addition, the administrator can use the CLI for
performing all levels of switch configuration.
To make the CLI easy to use, the various commands have been logically grouped into a series of menus and
submenus. Each menu displays a list of commands and/or submenus that are available, along with a summary of
what each command will do. Below each menu is a prompt where you can enter any command appropriate to the
current menu.
This chapter describes the Main Menu commands, and provides a list of commands and shortcuts that are
commonly available from all the menus within the CLI.
Main Menu
The Main Menu displays after a successful connection and login. The following table shows the Main Menu for the
administrator login. Some features are not available under the user login.
