NOTE 60-Watt PoE extends the IEEE Power of Ethernet Pl us standard to double the power per port to

60 W atts.

CAUTION Consider the following when connecting switches capable of supplying PoE:

The PoE models of the switches are PSE (Power Sourcing Equipment) that are capable of supplying DC power to attaching PD (Powered Devices). These devices include VoIP phones, IP cameras, and wireless access points. The PoE switches can detect and supply power to prestandard legacy PoE Powered Devices. Due to the support of legacy PoE, it is possible that a PoE switch acting as a PSE may mistakenly detect and supply power to an attaching PSE, including other PoE switches, as a legacy PD. Even though PoE switches are PSE, and as such should be powered by AC, they could be powered up as a legacy PD by another PSE due to false detection. When this happens, the PoE switch may not operate properly and may not be ab le to properly supply power to its attaching PDs. To prevent false detection, you should disable PoE on the ports on the PoE switches that are used to connect to PSEs. You should also first power up a PSE device before connecting it to a PoE switch. When a device is being falsely detected as a PD, you should disconnect the device from the PoE port and power recycle the device with AC power before reconnecting its PoE ports.

Quick Getting Started

Configuring98DX4203, 98DX4204, 98DX4210, 98DX4211, and 98DX4212 Switches

Before You Begin

The switch can be accessed and managed by two different methods; over your IP network using the web-based interface, or by using the switch’s comman d-line interface through the console port. Using the console port requires advanced user skills.

The following table shows the default settings used when configuring your switch for the first time.

Parameter Default Value

Username cisco Password cisco LAN IP 192.168.1.254

Configuring Your Switch Using the We b-based Interface

T o access the switch with a web-based interface, you must know the IP address that the switch is using. The switch uses the factory default IP address of 192.168.1.254, with a subnet of /24.

When the switch is using the factory default IP address, the System LED flashes continuously. When the switch is using a DHCP server-assigned IP address or an administrator has configured a static IP address, the System LED is a steady green (DHCP is enabled by default).

If you are managing the switch through a network connection and the switch IP address is changed, either by a DHCP server or manually, your access to the switch will be lost. You must enter the new IP address that the switch is using into your browser to use the web-based interface. If you are managing the switch through a console port connection, the link is retained.

To configure the switch using the web-based interface:

STEP 1 Power on the computer and your switch. STEP 2 For Cisco 350-550 XG switches, connect the computer to the OOB port found on the front

panel. For all other switches, connect the computer to any network port.

Quick Getting Started

Configuring98DX4203, 98DX4204, 98DX4210, 98DX4211, and 98DX4212 Switches

STEP 3 Set up the IP configuration on your computer.

a. If the switch is using the default static IP address of 192.168.1.254/24, you must choose an

IP address for the co mputer in the range of 192.168.1.2 to 192.1 68.1.253 that is not already in use.

b. If the IP addresses will be assigned b y DHCP, make sure that your DHCP server is running

and can be reached from the switch and the computer. You may need to disconnect and reconnect the devices for them to discover their new IP addresses from the DHCP server.

NOTE Details on how to change the IP address on your computer depend upon the type

of architecture and operating system that you are using. Use your computers local Help and Support functionality and search for “IP Addressing.”

STEP 4 Open a web browser window. If you are prompted to install an ActiveX plug-in when

connecting to the device, follow the prompts to accept the plug-in.

STEP 5 Enter the switch IP address in the address bar and press Enter. For example,

http://192.168.1.254.

STEP 6 When the login page appears, choose the language that you prefer to use in the web-based

interface and enter the username and password. The default username is cisco. The default password is cisco. Usernames and passwords are

both case sensitive.

STEP 7 Click Log In.

If this is the first time that you have logged on with the default username and password, the Change Password page opens. The rules for constructing a new password are displayed on the page.

STEP 8 Enter a new password and confirm the password.

NOTE Password complexity is enabled by default. The password must comply with the

default complexity rules or it can be disabled temporarily by checking Disable next to the Password Strength Enforcement option.

STEP 9 Click Apply.

CAUTION Make sure that any configuration changes made a re saved before exiting from the web-based

interface by clicking on the Save icon. Exiting before you save your configuration results in all changes being lost.

Cisco 350, 350X and 550X Series Managed Switches, Firmware Release 2.4, ver 0.4 17

The Getting Started page opens. You are now ready to configure the switch. Refer to the Administration Guide or see the help pages for further information.

Configuring Your Switch Using the Console Port

Browser Restrictions

If you are using IPv6 interfaces on your management station, use the IPv6 global address and not the IPv6 link local address to access the device from your browser.

Configuring Your Switch Using the Console Port

To configure the switch using the console port:

Quick Getting Started

STEP 1 Connect a computer to the switch console port using the supplied console cable. STEP 2 Start a console port utility such as HyperTerminal on the computer. STEP 3 Configure the utility with the following parameters:

• 115200 bits per second

• 8 data bits

• no parity

• 1 stop bit

• no flow control

STEP 4 Enter a username and password. The default username is cisco, and the default password is

cisco. Usernames and passwords are both case sensitive. If this is the first time that you have logged on with the default username and password, the

following message appears:

Please change your password from the default settings. Please change the password for better protection of your network. Do you want to change the password (Y/N) [Y]?

STEP 5 Enter Y, and set a new administrator password.

NOTE Password complexity is enabled by default. The password must comply with the

default complexity rules.

Out-Of-Band Port

CAUTION Make sure that any configuration changes made are saved before exiting.

Out-Of-Band Port

You are now ready to configure the switch. See the CLI Guide for your switch.

NOTE If you are not using DHCP on yo ur network, set the IP address t ype on the switch

to Static and change the static IP address and subnet mask to match your network topology . Failure to do so may result in multiple switches using the same factory default IP address of 192.168.1.2 54.

OOB is only supported on SG350XG/SX350X and SG550XG/SX550X devices. The switch supports an Out-of-Band (OOB) port. This port is used for the management

network. The out-of-band and the in-band ports share the same IP routing table, therefore you cannot use the same subnet on both in-band and out-of-band interfaces.

The OOB port is assigned an MAC address which is different from the base MAC address and the addresses of the in-band ports. This MAC address is used as the source MAC address in all frames (including IP frames) sent by the switch on the

OOB port. The IP address assigned to this port cannot be assigned to the in-band ports at the same time.

In addition, the IP address assigned to the OOB port must not belong to any IP subnet configured at the in-band interfaces of the devices.

By default, the OOB port is configured with the default IP address 192.168.1.254. This default IP address is used when no other address was assigned (dynamically or statically). This sub net is a reserved one and cannot be assigned on the in-band interfaces.

Bridging between the OOB port and the in-band Layer 2 interfaces is not supported. The OOB port cannot be a member of VLAN or LAG, and the bridge’s protocols (for example, STP, GVRP, etc.) cannot be enabled on the OOB port.

Only untagged traffic is supported on the OOB port.

Cisco 350, 350X and 550X Series Managed Switches, Firmware Release 2.4, ver 0.4 19

Out-Of-Band Port

Port Configuration

The following Ethernet configuration is supported for the OOB port:

• Speed (10/100/1000)

• Duplex

• Auto-negotiation

DHCP Client

DHCP client (IPv4 and IPv6) is enabled by default on the OOB por t and on the d efault VLAN.

Static route on OOB port

Static routes are supported on the OOB port.

IPv4 Address on OOB port

Only one IPv4 address can be defined on the OOB port. The default static IP address is set only on the OOB.

IP Applications

All IP applications, such as telnet, SSH, except for the following ones are supported on the OOB port:

• ARP Proxy

• Routing protocols

• Relay applications (DHCP, DHCPv6 and UDP)

QoS & ACL

QoS and ACL are not supported on the OOB port (so all TCAM-based features like DOS Attack Prevention are also not supported).

Only Management ACLs are supported.

USB Port

Stack Support

The OOB port name is always mapped to the physical OOB port of master unit. The physical OOB ports of slaves are not functional and will not establish a link when connected to a neighbor device or PC.

The USB port can be used for connecting external storage (disk-on-key) devices. It can hold configuration, SYSLOG and image files. In a stack, only the master’s USB port is active. The USB port fully supports the FAT32 file system, and provides partial support (read only) for the NTFS file system.

Both relative path or fully qualified paths can be used. The system supports the following user actions on the USB port through the GUI:

• Display the USB contents

• Copy files to/from USB (the same as with TFTP)

• Delete, rename and display the contents of USB files

Stacking the Switches

By default, the ports on a switch function as regular Ethernet ports, except if you configure them to do stacking. You cannot mix the stack speeds between the switches or ports.

See the front panel figures in 98DX4203, 98DX4204, 98DX4210, 98DX4211, and

98DX4212Switch Features to help with the stack port descriptions and supported modules.

WARNING Stack ports must be either configured with the sa m e port sp e ed or have th e sa m e sp ee d

capability on the module or cable plug in. If the port speed is configured as auto, then the module plugged into these two ports will need to have the same speed capability, otherwise the switch will not be able to form as a stack with multiple units.

A stack can have up to four 350X devices or eight 550X devices in it. Any 10G port of the switch can be used for stacking. The switch can only be stacked without Mesh topology.

Cisco 350, 350X and 550X Series Managed Switches, Firmware Release 2.4, ver 0.4 21

Quick Getting Started

The switches in the same stack are connected together through their stack ports. Depending on the type of stack ports and the desired speed, you may need Cat6a Ethernet cables or Cisco approved modules or cables for the switches.

• The Cisco SFP+ Copper Cable modules for stacking that are supported in the Cisco

switches are: SFP-H10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M.

• The SFP+ port is a combination port, shared with one other RJ-45 port. When the

SFP+ is active, the adjacent RJ-45 port is disabled.

• Some SFP interfaces are shared with one other RJ-45 port, called a combo port. When

the SFP is active, the adjacent RJ-45 port is disabled.

• The LEDs of the corresponding RJ-45 port flash green to respond to the SFP interface

traffic.

• OOB Port (if present)—The Out of Band (OOB) port is a CPU Ethernet port that can

be used only as a management interface. Bridging between the OOB port and the inband Layer 2 interface is not supported. This does not appear on 250 devices.

Front Panel LEDs

The following are the global LEDs found on the devices:

• Master—(Green) The LED lights steady when the switch is a stack master.

• System—(Green) The LED lights steady when the switch is powered on, and flashes

when booting, performing self-tests, or acquiring an IP address. If the LED flashes Green, the switch has detected a hardware failure, a firmware failure, and/or a configuration file error.

• Stack ID—(Green) The LED lights steady when the switch is stacked and the

corresponding number indicates its Stack ID.

General Information

Basic or Advanced Display Mode

When the user switches from advanced to basic, the browser reloads the page. If the page exists also on the basic mode, the user stays on the same page. If the page does not exist in the basic mode, the browser will load the first page of the folder which was used by the user . If the folder does not exist, the Getting Started page will be displayed.

If there is advanced configuration, and the page is loaded in basic mode, a page-level message will be displayed to the user (e.g. there are 2 radius server configured but in basic mode only a single server can be displayed, or there is 802.1X port authentication with time range configured but time range is not visible in basic mode).

When switching from one mode to another, any configuration which was made on the page (without Apply) is deleted.

The Health and Power page monitors the temperature status, power supply st atus and fan status on all relevant devices. Depending on the model, there are one or more fans on a device. Some models have no fans at all.

Redundant Power

This feature is only supported on the SG550 series. The RPS 2300 is a backup for AC power. It is used for su pplying power to the device if th e AC

power supply stops working. It is only supported on the 550 family. If it becomes necessary to switch to the backup power, the device changes between the power

sources without reboot and without any disruption to the device operation. The device polls the RPS status every 1 sec, if RPS is providing power, the RPS LED is set, and if the RPS is active, a SYSLOG is generated.

When main power supply is again operational, the devices notifies the RPS to stop providing power. A SYSLOG is generated.

The RPS LED (on the device front panel) displays the current RPS status:

• Off – RPS is not connected

• Green (solid) – RPS is ready

• Amber (blinking) – RPS is currently supplying power to the device

• Amber (solid) – RPS is connected but providing power to two other devices. In this

case, the RPS will not be able to provide power to the current device, while providing power to the two other devices.

Switched Port Analyzer (SPAN and RSPAN)

Status and Statistics

Switched Port Analyzer (SPAN and RSPAN)

The SPAN feature, which is sometimes called port mirroring or port monitoring, selects network traffic for analysis by a network analyzer. The network analyzer can be a Cisco SwitchProbe device or other Remote Monitoring (RMON) probes.

Port mirroring is used on a network device to send a copy of network packets, seen on a single device port, multiple device ports, or an entire VLAN, to a network monitoring connection on another port on the device. This is commonly used when monitoring of network traffic, such as for an intrusion-detection system, is required. A network analyzer, connected to the monitoring port, processes the data packets.

The device can mirror up to eight interfaces per session. A packet, which is received on a network port and assigned to a VLAN that is subject to

mirroring, is mirrored to the analyzer port even if the packet was eventually trapped or discarded. Packets sent by the device are mirrored when Transmit (Tx) mirroring is activated.

Mirroring does not guarantee that all traffic from the source port(s) is received on the analyzer (destination) port. If more data is sent to the analyzer port than it can support, some data might be lost.

VLAN mirroring cannot be active on a VLAN that was not manually created. For example, if VLAN 23 was created by GVRP, port mirroring will not work on it.

Switched Port Analyzer (SPAN and RSPAN)

Remote SPAN

RSPAN extends SPAN by enabling monitoring of multiple switches across your network and allowing the analyzer port to be defined on a remote switch. In addition to the start (source) and final (destination) switches, you can define intermediate switches over which the traffic flows, as shown in Figure 1.

Figure 1 RSPAN Switch Deployment:

The traffic for each RSPAN session is carried over a user-specified RSPAN VLAN that is dedicated for that RSPAN session in all participating switches. The traffic from the source interfaces on the start device is copied to the RSPAN VLAN through a reflector port and then forwarded over trunk ports on the intermediate devices to the destination session on the final switch, which is monitoring the RSPAN VLAN.

The reflector port is the mechanism that copies packets to an RSPAN VLAN. It is a network port that handles various types of traffic.

The RSPAN VLAN must be configured on all the intermediate switches.

NOTE RSPAN does not always successfully copy all the packets when they are arrive from multiple

sources simultaneously. If accurate monitoring is required, the TCAM-based mirror policy can be used.

RSPAN Workflow

The following workflow describes how to configure the start, intermediate and final switches:

RMON

RMON (Remote Networking Monitoring) enables an SNMP agent in the device to proactively monitor traffic statistics over a given period and send traps to an SNMP manager. The local SNMP agent compares actual, real-time counters against predefined thresholds and generates alarms, without the need for polling by a central SNMP management platform. This is an effective mechanism for proactive management, provided that you have set the correct thresholds relative to your network’s base line.

RMON decreases the traffic between the manager and the device since the SNMP manager does not have to poll the device frequently for information, and enables the manager to get timely status reports, since the device reports events as they occur.

With this feature, you can perform the following actions:

• V iew the current statistics (from the time that the counter values cleared). You can also

collect the values of these counters over a period of time, and then view the table of collected data, where each collected set is a single line of the History tab.

• Define interesting changes in counter values, such as “reached a certain number of late

collisions” (defines the alarm), and then specify what action to perform when this event occurs (log, trap, or log and trap).

RMON Events Logs

The Events page displays the log of events (actions) that occurred. Two types of events can be logged: Log or Log and Trap. The action in the event is performed when the event is bound to an alarm (see the RMON Alarms page) and the conditions of the alarm have occurred.

STEP 1 Click Status and Statistics > RMON > Events. STEP 2 Click Event Log Table.

You can select an interface in the filter to view events on a specific interface. This page displays the following fields:

• Event Entry No.—Event’s log entry number.

• Log No.—Log number (within the event).

• Log Time—Time that the log entry was entered.

• Description—Description of event that triggered the alarm.

RMON Alarms

RMON alarms provide a mechanism for setting thresholds and sampling intervals to generate exception events on counters or any other SNMP object count er maintained by the agent. Both the rising and falling thresholds must be configured in the alarm. After a rising threshold is crossed, no rising events are generated until the companion falling threshold is crossed. After a falling alarm is issued, the next alarm is issued when a rising threshold is crossed.

One or more alarms are bound to an event, which indicates the action to be taken when the alarm occurs.

Alarm counters can be monitored by either absolute values or changes (delta) in the counter values.

Status and Statistics

sFlow

• Owner—Enter the name of the user or network management system that receives the

alarm.

STEP 4 Click Apply. The RMON alarm is saved to the Running Configuration file.

The sFlow feature enables co lle cting statistics using the sFlow sampling technology, based on sFlow V5.

This sampling technology is embedded within switches and routers. It provides the ability to continuously monitor traffic flows on some or all the interfaces, simultaneously.

The sFlow monitoring system consists of an sFlow agent (embedded in a switch or router or in a stand alone probe) and a central data collector, known as the sFlow collector.

The sFlow agent uses sampling technology to capture traffic and statistics from the device it is monitoring. sFlow datagrams are used to forward the sampled traffic and statistics to an sFlow collector for analysis.

sFlow V5 defines:

• How traffic is monitored.

• The sFlow MIB that controls the sFlow agent.

• The format of the sample data used by the sFlow agent when forwarding data to a

central data collector. The device provides support for two types of sFlow sampling: flow sampling and counters sampling. The following counters sampling is performed according to sFlow V5 (if supported by the interface):

- Generic interface counters (RFC 2233)

- Ethernet interface counters (RFC 2358)

Workflow

By default, flow and counter sampling are disabled.
