This section provides an introduction to the web-based configuration utility, and covers the following topics:

• Starting the Web-based Switch Configuration Utility

• Quick Start Switch Configuration

• Interface Naming Conventions

• Window Navigation

Starting the Web-based Switch Configuration Utility

This section describes how to navigate the web-based switch configuration utility.

If you are using a pop-up blocker, make sure it is disabled.

Browsers have the following restrictions:

• If you are using older versions of Internet Explorer, you cannot directly use

an IPv6 address to access the switch. You can, however, use the DNS (Domain Name System) server to create a domain name that contains the IPv6 address, and then use that domain name in the address bar in place of the IPv6 address.

• If you have multiple IPv6 interfaces on your management station, use the

IPv6 global address instead of the IPv6 link local address to access the switch from your browser.

Cisco Small Business 200 Series Smart Switch Administration Guide 7

Getting Started

Starting the Web-based Switch Configuration Utility

Launching the Configuration Utility

To open the web-based configuration utility:

STEP 1 Open a Web browser.

STEP 2 Enter the IP address of the switch you are configuring in the address bar on the

browser, and then press Enter. The

Logging In

page opens.

The default username is cisco and the default password is cisco. The first time that you log in with the default username and password, you are required to enter a new password.

NOTE If you have not previously selected a language for the GUI, the language of the Login

page is determined by the language(s) requested by your browser and the languages configured on your switch. If your browser requests Chinese, for example, and Chinese has been loaded into your switch, the Login page is automatically displayed in Chinese. If Chinese has not been loaded into your switch, the Login page is displayed in English.

The languages loaded into the switch have a language and country code (en-US, en-GB and so on). For the Login page to be automatically displayed in a particular language, based on the browser request, both the language and country code of the browser request must match those of the language loaded on the switch. If the browser request contains only the language code without a country code (for example: fr). The first embedded language with a matching language code is taken (without matching the country code, for example: fr_CA).

To log in to the device configuration utility:

STEP 1 Enter the username/password. The password can contain up to 64 ASCII

characters. Password-complexity rules are described in the Setting Password

Complexity Rules section of the Configuring Security chapter.

STEP 2 If you are not using English, select the desired language from the Language drop-

down menu. To add a new language to the switch or update a current one, refer to the Upgrade/Backup Firmware/Language section.

Logging Out

By default, the application logs out after ten minutes of inactivity. You can change this default value as described in the Defining Idle Session Timeout section in the

General Administrative Information and Operations chapter.

CAUTION Unless the Running Configuration is copied to the Startup Configuration, rebooting

the switch will remove all changes made since the last time the file was saved. Save the Running Configuration to the Startup Configuration before logging off to preserve any changes you made during this session.

A flashing red X icon to the left of the Save application link indicates that Running Configuration changes have not yet been saved to the Startup Configuration file. The flashing can be disabled by clicking on the Disable Save Icon Blinking button on the Copy/Save Configuration page

When the switch auto-discovers a device, such as an IP phone (see Chapter 10,

“What is a Smartport”), and it configures the port appropriately for the device.

These configuration commands are written to the Running Configuration file. This causes the Save icon to begin blinking when the you log on even though you did not make any configuration changes.

When you click Save, the Copy/Save Configuration page is displayed. Save the Running Configuration file by copying it to the Startup Configuration file. After this save, the red X icon and the Save application link are no longer displayed.

To logout, click Logout in the top right corner of any page. The system logs out of the switch.

When a timeout occurs or you intentionally log out of the system, a message is displayed and the state. After you log in, the application returns to the initial page.

The initial page displayed depends on the “Do not show this page on startup” option in the Getting Started page. If you did not select this option, the initial page is the Getting Started page. If you did select this option, the initial page is the System Summary page.

Cisco Small Business 200 Series Smart Switch Administration Guide 24

Managing System Logs

This section describes the System Log feature, which enables the switch to generate several independent logs. Each log is a set of messages describing system events.

The switch generates the following local logs:

• Log sent to the console interface.

• Log written into a cyclical list of logged events in the RAM and erased when

the switch reboots.

• Log written to a cyclical log-file saved to the Flash memory and persists

across reboots.

In addition, you can send messages to remote SYSLOG servers in the form of SYSLOG messages.

This section covers the following sections:

• Setting System Log Settings

• Setting Remote Logging Settings

• Viewing Memory Logs

Setting System Log Settings

You can enable or disable logging on the Log Settings page, and select whether to aggregate log messages.

You can select the events by severity level. Each log message has a severity level marked with the first letter of the severity level concatenated with a dash (-) on each side (except for Emergency that is indicated by the letter F). For example, the log message "%INIT-I-InitCompleted: … " has a severity level of I, meaning Informational.

Cisco Small Business 200 Series Smart Switch Administration Guide 25

Managing System Logs

Setting System Log Settings

The event severity levels are listed from the highest severity to the lowest severity, as follows:

• Emergency—System is not usable.

• Alert—Action is needed.

• Critical—System is in a critical condition.

• Error—System is in error condition.

• Warning—System warning has occurred.

• Notice—System is functioning properly, but a system notice has occurred.

• Informational—Device information.

• Debug—Detailed information about an event.

You can select different severity levels for RAM and Flash logs. These logs are displayed in the RAM Memory page and Flash Memory page, respectively.

Selecting a severity level to be stored in a log causes all of the higher severity events to be automatically stored in the log. Lower severity events are not stored in the log.

For example, if Warning is selected, all severity levels that are Warning and higher are stored in the log (Emergency, Alert, Critical, Error, and Warning). No events with severity level below Warning are stored (Notice, Informational, and Debug).

To set global log parameters:

STEP 1 Click Administration > System Log > Log Settings. The Log Settings page

opens.

STEP 2 Enter the parameters.

• Logging—Select to enable message logging.

• Syslog Aggregator—Select to enable the aggregation of SYSLOG

messages and traps. If enabled, identical and contiguous SYSLOG messages and traps are aggregated over the specified Max Aggregation Time and sent in a single message. The aggregated messages are sent in the order of their arrival. Each message states the number of times it was aggregated.

• Max Aggregation Time—Enter the interval of time that SYSLOG messages

are aggregated.

Types of System Files

System files are files that contain configuration information, firmware images or boot code.

Various actions can be performed with these files, such as: selecting the firmware file from which the switch boots, copying various types of configuration files internally on the switch, or copying files to or from an external device, such as an external server.

The possible methods of file transfer are:

• Internal copy.

• HTTP/HTTPS that uses the facilities that the browser provides.

• TFTP client, requiring a TFTP server.

Configuration files on the switch are defined by their type, and contain the settings and parameter values for the device.

Cisco Small Business 200 Series Smart Switch Administration Guide 30

Managing System Files

Ty p es of Sy s te m Fi le s

When a configuration is referenced on the switch, it is referenced by its configuration file type (such as Startup Configuration or Running Configuration), as opposed to a file name that can be modified by the user.

Content can be copied from one configuration file type to another, but the names of the file types cannot be changed by the user.

Other files on the device include firmware, boot code, and log files, and are referred to as operational files.

The configuration files are text files and can be edited in a text editor, such as Notepad after they are copied to an external device, such as a PC.

Files and File Types

The following types of configuration and operational files are found on the switch:

• Running Configuration—Contains the parameters currently being used by

the switch to operate. This is the only file type that is modified when you change parameter values on the device.

If the switch is rebooted, the Running Configuration is lost. The Startup Configuration, stored in Flash, overwrites the Running Configuration, stored in RAM.

To preserve any changes you made to the switch, you must save the Running Configuration to the Startup Configuration, or another file type.

• Startup Configuration—The parameter values that were saved by copying

another configuration (usually the Running Configuration) to the Startup Configuration.

The Startup Configuration is retained in Flash and is preserved when the switch is rebooted. At this time, the Startup Configuration is copied to RAM and identified as the Running Configuration.

• Mirror Configuration—A copy of the Startup Configuration, created by the

switch when the following conditions exist:

- The switch has been operating continuously for 24 hours.

- No configuration changes have been made to the Running Configuration

in the previous 24 hours.

- The Startup Configuration is identical to the Running Configuration.

Only the system can copy the Startup Configuration to the Mirror Configuration. However, you can copy from the Mirror Configuration to other file types or to another device.

Cisco Small Business 200 Series Smart Switch Administration Guide 31

Managing System Files

Ty p es of Sy s te m Fi le s

The option of automatically copying the Running Configuration to the mirror configuration can be disabled in the Configuration Files Properties page.

• Backup Configuration—A manual copy of a configuration file used for

protection against system shutdown or for the maintenance of a specific operating state. You can copy the Mirror Configuration, Startup Configuration, or Running Configuration to a Backup Configuration file. The Backup Configuration exists in Flash and is preserved if the device is rebooted.

• Firmware—The program that controls the operations and functionality of

the switch. More commonly referred to as the image.

• Boot Code—Controls the basic system startup and launches the firmware

image.

• Language File—The dictionary that enables the web-based configuration

utility windows to be displayed in the selected language.

• Flash Log—SYSLOG messages stored in Flash memory.

File Actions

The following actions can be performed to manage firmware and configuration files:

• Upgrade the firmware or boot code, or replace a second language, as

described in Upgrade/Backup Firmware/Language section.

• Save configuration files on the switch to a location on another device as

described in the Downloading or Backing-up a Configuration or Log section.

• Clear the Startup Configuration or Backup Configuration file types as

described in the Viewing Configuration Files Properties section.

• Copy one configuration file type to another configuration file type as

described in the Copying Configuration Files section.

• Enable automatically uploading a configuration file from a DHCP server to

the switch, as described in the DHCP Auto Configuration section.

DHCP Auto Configuration

The switch supports DHCP auto configuration, which provides a means of passing configuration information (including the IP address of a TFTP server and a file name) to hosts on a TCP/IP network. Based on this protocol, the Auto Configuration feature enables a switch to download configuration files from a TFTP server.

By default, the switch is enabled as a DHCP client when the Auto Configuration feature is enabled.

Cisco Small Business 200 Series Smart Switch Administration Guide 40

Managing System Files

DHCP Auto Configuration

Triggering DHCP Auto Configuration

The Auto Configuration process is triggered in the following cases:

• After reboot when an IP address is allocated or renewed dynamically (using

DHCP).

• Upon an explicit DHCP renewal request and if the switch and the server are

configured to do so.

• Upon automatic renewal of the DHCP lease.

Server Name/Address

You can specify the IP address or the name of the TFTP server. This server is used if no server IP address was specified in the DHCP message. This DHCP message is the DHCP offer message coming from the DHCP server. Possible options are bootp options sname and siaddr and DHCP option 150 or option 66. This is an optional parameter.

Backup Configuration File Name

You can specify the backup configuration filename. This file is used if no filename was specified in the DHCP message. This is an optional parameter.

Auto Configuration Process

When the Auto Configuration process is triggered, the following sequence of events occurs:

• The DHCP server is accessed to acquire the TFTP server IP address and

configuration file name. These parameters are passed in the DHCP option parameters.

• If an IP address was not supplied by the DHCP server, the backup server

address is used (if configured by the user).

• If the IP address was not supplied by the DHCP server and the backup

TFTP server address parameter is empty then the Auto Configuration process is halted.

NOTE In the previous two bullets, the IP address refers to the IP address or

hostname of the TFTP server.

Cisco Small Business 200 Series Smart Switch Administration Guide 41

Managing System Files

DHCP Auto Configuration

• If the configuration filename was supplied by the DHCP server, then the

copy protocol (TFTP) is selected as described in DHCP Auto

Configuration.

• If a configuration filename was not supplied by the DHCP server, the

backup configuration file name is used.

• If the configuration filename was not supplied by the DHCP server and the

backup configuration file name is empty, the Auto Configuration process is halted.

• The TFTP server is accessed to download the file from it.

The download process is done only if the new configuration filename is different from the current configuration filename (even if the current configuration file is empty).

• A SYSLOG message is generated acknowledging that the Auto

Configuration process is completed.

Note the following regarding the DHCP auto configuration process:

• A configuration file that is placed on the TFTP server must match the form

and format requirements of a supported configuration file. The form and format of the file are checked, but the validity of the configuration parameters is not checked prior to loading it to the Startup Configuration.

• To ensure that the device configuration functions as intended, due to

allocation of different IP addresses with each DHCP renew cycle, it is recommended that IP addresses be bound to MAC addresses in the DHCP server table. This ensures that each device has its own reserved IP address and other relevant information.

STEP 3 Click Apply to set the configuration settings on the switch.

Pinging a Host

Ping is a utility used to test if a remote host can be reached and to measure the round-trip time for packets sent from the switch to a destination device.

Ping operates by sending Internet Control Message Protocol (ICMP) echo request packets to the target host and waiting for an ICMP response, sometimes called a pong. It measures the round-trip time and records any packet loss.

To ping a host:

STEP 1 Click Administration > Ping. The Ping page

STEP 2 Configure ping by entering the fields:

• Host Definition—Select whether to specify hosts by their IP address or

name.

• IP Version—If the host is identified by its IP address, select either IPv4 or

IPv6 to indicate that it will be entered in the selected format.

• IPv6 Address Type—Select Link Local or Global as the type of IPv6

address to enter.

- Link Local—The IPv6 address uniquely identifies hosts on a single

System Time

Synchronized system clocks provide a frame of reference between all devices on the network. Network time synchronization is critical because every aspect of managing, securing, planning, and debugging a network involves determining when events occur. Without synchronized clocks, accurately correlating log files between devices when tracking security breaches or network usage is impossible.

Synchronized time also reduces confusion in shared file systems, as it is important for the modification times to be consistent, regardless of the machine on which the file systems reside.

For these reasons, it is important that the time configured on all of the devices on the network is accurate.

NOTE The switch supports Simple Network Time Protocol (SNTP) and when enabled, the

switch dynamically synchronizes the switch time with time from an SNTP server. The switch operates only as an SNTP client, and cannot provide time services to other devices.

This section describes the options for configuring the system time, time zone, and Daylight Savings Time (DST). It covers the following topics:

• System Time Options

• SNTP Modes

• Configuring System Time

Cisco Small Business 200 Series Smart Switch Administration Guide 52

System Time

System Time Options

System time can be set manually by the user, dynamically from an SNTP server, or synchronized from the PC running the GUI. If an SNTP server is chosen, the manual time settings are overwritten when communications with the server are established.

As part of the boot process, the switch always configures the time, time zone, and DST. These parameters are obtained from the PC running the GUI, SNTP, values set manually, or if all else fails, from the factory defaults.

Time

The following methods are available for setting the system time on the switch:

• Manual—You must manually sets the time.

• From PC—Time can be received from the PC by using browser information.

The configuration of time from the computer is saved to the Running Configuration file. You must copy the Running Configuration to the Startup Configuration in order to enable the device to use the time from the computer after reboot. The time after reboot is set during the first WEB login to the device.

When you configure this feature for the first time, if the time was not already set, the device sets the time from the PC.

This method of setting time works with both HTTP and HTTPS connections.

• SNTP—Time can be received from SNTP time servers. SNTP ensures

accurate network time synchronization of the switch up to the millisecond by using an SNTP server for the clock source. When specifying an SNTP server, if choosing to identify it by hostname, three suggestions are given in the GUI:

- time-a.timefreq.bldrdoc.gov

- time-b.timefreq.bldrdoc.gov

- time-c.timefreq.bldrdoc.gov

After the time has been set by any of the above sources, it is not set again by the browser.

NOTE SNTP is the recommended method for time setting.

Cisco Small Business 200 Series Smart Switch Administration Guide 53

System Time

SNTP Modes

Time Zone and Daylight Savings Time (DST)

The Time Zone and DST can be set on the switch in the following ways:

• Dynamic configuration of the switch through a DHCP server, where:

- Dynamic DST, when enabled and available, always takes precedence

over the manual configuration of DST.

- If the server supplying the source parameters fails, or dynamic

configuration is disabled by the user, the manual settings are used.

- Dynamic configuration of the time zone and DST continues after the IP

address lease time has expired.

• Manual configuration of the time zone and DST becomes the Operational

time zone and DST, only if the dynamic configuration is disabled or fails.

SNTP Modes

NOTE The DHCP server must supply DHCP option 100 in order for dynamic

time zone configuration to take place.

The switch can receive the system time from an SNTP server in one of the following ways:

• Client Broadcast Reception (passive mode)

SNTP servers broadcast the time, and the switch listens to these broadcasts. When the switch is in this mode, there is no need to define a Unicast SNTP server.

• Client Broadcast Transmission (active mode)—The switch, as an SNTP

client, periodically requests SNTP time updates. This mode works in either of the following ways:

- SNTP Anycast Client Mode—The switch broadcasts time request

packets to all SNTP servers in the subnet, and waits for a response.

- Unicast SNTP Server Mode—The switch sends Unicast queries to a list

The switch supports having all of the above modes active at the same time and selects the best system time received from an SNTP server, according to an algorithm based on the closest stratum (distance from the reference clock).

Configuring Port and VLAN Mirroring

Port mirroring is used on a network switch to send a copy of network packets seen on one switch port, multiple switch ports, or an entire VLAN to a network monitoring connection on another port on the switch. This is commonly used for network appliances that require monitoring of network traffic, such as an intrusiondetection system. A network analyzer connected to the monitoring port processes the data packets for diagnosing, debugging, and performance monitoring. Up to eight sources can be mirrored. This can be any combination of eight individual ports and/or VLANs.

Cisco Small Business 200 Series Smart Switch Administration Guide 65

Managing Device Diagnostics

Configuring Port and VLAN Mirroring

A packet that is received on a network port 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 switch 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.

Only one instance of mirroring is supported system-wide. The analyzer port (or target port for VLAN mirroring or port mirroring) is the same for all the mirrored VLANs or ports.

selection.

LLDP (Link Layer Discovery Protocol) and CDP (Cisco Discovery Protocol) are link layer protocols for directly-connected LLDP and CDP-capable neighbors to advertise themselves and their capabilities to each other. By default, the switch sends an LLDP/CDP advertisement periodically to all its interfaces and terminates and processes incoming LLDP and CDP packets as required by the protocols. In LLDP and CDP, advertisements are encoded as TLV (Type, Length, Value) in the packet.

The following CDP/LLDP configuration notes apply:

• CDP/LLDP can be globally enabled or disabled and enabled/disabled per

port. The CDP/LLDP capability of a port is relevant only if CDP/LLDP is globally enabled.

• If CDP/LLDP is globally enabled, the switch filters out incoming CDP/LLDP

packets from ports that are CDP/LLDP-disabled.

• If CDP/LLDP is globally disabled, the switch can be configured to discard,

VLAN-aware flooding, or VLAN-unaware flooding of all incoming CDP/LLDP packets. VLAN-aware flooding floods an incoming CDP/LLDP packet to the VLAN where the packet is received excluding the ingress port. VLANunaware flooding floods an incoming CDP/LLDP packet to all the ports excluding the ingress port. The default is to discard CDP/LLDP packets when CDP/LLDP is globally disabled. You can configure the discard/ flooding of incoming CDP and LLDP packets from the CDP Properties page and the LLDP Properties page respectively.

LAG, CDP/LLDP transmit packets on each port without taking into account the fact that the ports are in a LAG.

The operation of CDP/LLDP is independent of the STP status of an interface.

If 802.1x port access control is enabled at an interface, the switch transmits and receives CDP/LLDP packets to and from the interface only if the interface is authenticated and authorized.

If a port is the target of mirroring, then according to CDP/LLDP it is considered down.

NOTE CDP and LLDP are link layer protocols for directly-connected CDP/LLDP capable

devices to advertise themselves and their capabilities. In deployments where the CDP/LLDP-capable devices are not directly connected and are separated with CDP/LLDP-incapable devices, the CDP/LLDP-capable devices may be able to receive the advertisement from other device(s) only if the CDP/LLDP-incapable devices flood the CDP/LLDP packets they receives. If the CDP/LLDP-incapable devices perform VLAN-aware flooding, then CDP/LLDP-capable devices can hear each other only if they are in the same VLAN. A CDP/LLDP-capable device may receive advertisement from more than one device if the CDP/LLDP-incapable devices flood the CDP/LLDP packets.

LLDP Overview

LLDP is a protocol that enables network managers to troubleshoot and enhance network management in multi-vendor environments. LLDP standardizes methods for network devices to advertise themselves to other systems, and to store discovered information.

LLDP enables a device to advertise its identification, configuration, and capabilities to neighboring devices that then store the data in a Management Information Base (MIB). The network management system models the topology of the network by querying these MIB databases.

LLDP is a link layer protocol. By default, the switch terminates and processes all incoming LLDP packets as required by the protocol.

The LLDP protocol has an extension called LLDP Media Endpoint Discovery (LLDP-MED), which provides and accepts information from media endpoint devices such as VoIP phones and video phones. For further information about LLDP-MED, see LLDP MED.

LLDP Configuration Workflow

Following are examples of actions that can be performed with the LLDP feature and in a suggested order. You can refer to the LLDP/CDP section for additional guidelines on LLDP configuration. LLDP configuration pages are accessible under the Administration > Discovery LLDP menu.

Setting LLDP MED Network Policy

An LLDP-MED network policy is a related set of configuration settings for a specific real-time application such as voice, or video. A network policy, if configured, can be included in the outgoing LLDP packets to the attached LLDP media endpoint device. The media endpoint device must send its traffic as specified in the network policy it receives. For example, a policy can be created for VoIP traffic that instructs VoIP phone to:

• Send voice traffic on VLAN 10 as tagged packet and with 802.1p priority 5.

• Send voice traffic with DSCP 46.

Network policies are associated with ports by using the LLDP MED Port Settings page. An administrator can manually configure one or more network policies and the interfaces where the policies are to be sent. It is the administrator's responsibility to manually create the VLANs and their port memberships according to the network policies and their associated interfaces.

In addition, an administrator can instruct the switch to automatically generate and advertise a network policy for voice application based on the voice VLAN maintained by the switch. Refer the Auto Voice VLAN section for details on how the switch maintains its voice VLAN.

To define an LLDP MED network policy:

STEP 1 Click Administration > Discovery - LLDP > LLDP MED Network Policy. The

Configuring CDP

This section describes how to configure CDP.

It covers the following topics:

Setting CDP Properties

• Setting CDP Properties

• Editing CDP Interface Settings

• Displaying CDP Local Information

• Displaying CDP Neighbors Information

• Viewing CDP Statistics

Similar to LLDP, CDP (Cisco Discovery Protocol) is a link layer protocol for directly connected neighbors to advertise themselves and their capabilities to each other. Unlike LLDP, CDP is a Cisco proprietary protocol.

CDP Configuration Workflow

The followings is sample workflow in configuring CDP on the switch. You can also find additional CDP configuration guidelines in the LLDP/CDP section.

STEP 1 Enter the CDP global parameters using the CDP Properties page

STEP 2 Configure CDP per interface using the Interface Setting page

STEP 3 If Auto Smartport is to detect the capabilities of CDP devices, enable CDP in the

Smartport Properties page.

See the Identifying Smartport Type section for a description of how CDP is used to identify devices for the Smartport feature.

To enter CDP general parameters:

STEP 1 Click Administration > Discovery - CDP > Properties. The Properties page

opens.

STEP 2 Enter the parameters.

• CDP Status—Select to enable CDP on the switch.

to all the ports excluding the ingress ports.

• CDP Voice VLAN Advertisement—Select to enable the switch to advertise

the voice VLAN in CDP on all of the ports that are CDP enabled, and are member of the voice VLAN. The voice VLAN is configured in the Voice VLAN Properties page.

• CDP Mandatory TLVs Validation—If selected, incoming CDP packets not

containing the mandatory TLVs are discarded and the invalid error counter is incremented.

• CDP Version—Select the version of CDP to use.

• CDP Hold Time—Amount of time that CDP packets are held before the

packets are discarded, measured in multiples of the TLV Advertise Interval. For example, if the TLV Advertise Interval is 30 seconds, and the Hold Multiplier is 4, then the LLDP packets are discarded after 120 seconds. The following options are possible:

- Use Default—Use the default time (180 seconds)

—Delete the packet.

—VLAN unaware flooding that forwards incoming CDP packets

- User Defined—Enter the time in seconds.

• CDP Transmission Rate—The rate in seconds at which CDP advertisement

updates are sent. The following options are possible:

- Use Default—Use the default rate (60 seconds)

- User Defined—Enter the rate in seconds.

• Device ID Format—Select the format of the device ID (MAC address or

serial number).

• Source Interface—IP address to be used in the TLV of the frames. The

following options are possible:

- Use Default—Use the IP address of the outgoing interface.

- User Defined—Use the IP address of the interface (in the Interface field)

in the address TLV.

a voice VLAN mismatch is detected. This means that the voice VLAN information in the incoming frame does not match what the local device is advertising.

• Syslog Native VLAN Mismatch—Check to send a SYSLOG message when

a native VLAN mismatch is detected. This means that the native VLAN information in the incoming frame does not match what the local device is advertising.

• Syslog Duplex Mismatch—Check to send a SYSLOG message when

duplex information is mismatched. This means that the duplex information in the incoming frame does not match what the local device is advertising.

STEP 3 Click Apply. The LLDP properties are defined.

Editing CDP Interface Settings

Use the notification per port, and to select the TLVs included in LLDP PDUs.

By setting these properties it is possible to select the types of information to be provided to devices that support the LLDP protocol.

The LLDP-MED TLVs to be advertised can be selected in the LLDP MED Interface Settings page.

To define the LLDP interface settings:
