SMC may, at its own discretion, repair or replace any product not operating as warranted with a similar or functionally equivalent product, during the applicable warranty term. SMC will endeavor to repair or replace any product returned under warranty within 30 days of receipt of the product.

The standard limited warranty can be upgraded to a Limited Lifetime* warranty by registering new products within 30 days of purchase from SMC or its Authorized Reseller. Registration can be accomplished via the enclosed product registration card or online via the SMC web site. Failure to register will not affect the standard limited warranty. The Limited Lifetime warranty covers a product during the Life of that Product, which is defined as the period of time during which the product is an “Active” SMC product. A product is considered to be “Active” while it is listed on the current SMC price list. As new technologies emerge, older technologies become obsolete and SMC will, at its discretion, replace an older product in its product line with one that incorporates these newer technologies. At that point, the obsolete product is discontinued and is no longer an “Active” SMC product.

SMC is not responsible for these items if they are returned with the product.

Customers must contact SMC for a Return Material Authorization number prior to returning any product to SMC. Proof of purchase may be required. Any product returned to SMC without a valid Return Material Authorization (RMA) number clearly marked on the outside of the package will be returned to customer at customer’s expense.

Description of 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. Port-based and private 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. Some of the management features are briefly described below.

Configuration Backup and Restore – You can save the current configuration settings to a file on a TFTP server, and later download this file to restore the switch configuration settings.

Authentication – This switch authenticates management access via the console port, Telnet or 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 the Extensible Authentication Protocol over LANs (EAPOL) to request user credentials from the 802.1X client, and then verifies the client’s right to access the network via an authentication server.

Other authentication options include HTTPS for secure management access via the web, SSH for secure management access over a Telnet-equivalent connection, IP address filtering for SNMP/web/Telnet management access, and MAC address filtering for port access.

Access Control Lists – ACLs provide packet filtering for IP frames (based on address, protocol, or TCP/UDP port number) or any frames (based on MAC address or Ethernet type). ACLs can be 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, 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.

Rate Limiting – This feature controls the maximum rate for traffic received on an interface. Rate limiting is configured on interfaces at the edge of a network to limit traffic into the network. Packets that exceed the acceptable amount of traffic are dropped.

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 IEEE

802.3ad Link Aggregation Control Protocol (LACP). 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 8 trunks.

Broadcast Storm Control – Broadcast suppression prevents broadcast 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.

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 – 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.

Spanning Tree Algorithm – The switch supports these spanning tree protocols:

Spanning Tree Protocol (STP, IEEE 802.1D) – This protocol provides loop detection and recovery by allowing two or more redundant connections to be created between a pair of LAN segments. 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 3 to 5 seconds, compared to 30 seconds or more for the older IEEE 802.1D STP

1-5

NTRODUCTION

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).

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.

• 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.

Traffic Prioritization – This switch prioritizes each packet based on the required level of service, using four priority queues with strict or Weighted Round Robin Queuing. It uses IEEE 802.1p and 802.1Q tags to prioritize incoming traffic based on input from the end-station application. These

This switch also supports several common methods of prioritizing layer 3/ 4 traffic to meet application requirements. Traffic can be prioritized based on the DSCP field in the IP frame. 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.

Quality of 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. It also supports Multicast VLAN Registration (MVR) which allows common multicast traffic, such as television channels, to be transmitted across a single network-wide multicast VLAN shared by hosts residing in other standard or private VLAN groups, while preserving security and data isolation for normal traffic.

Connecting to the Switch

Configuration Options

The switch includes a built-in network management agent. The agent offers a variety of management options, including SNMP, RMON (Groups 1, 2, 3, 9) and a web-based interface. A PC may also be connected directly to the switch for configuration and monitoring via a command line interface (CLI).

Note: The IP address for this switch is obtained via DHCP by default.

To change this address, see

The switch’s HTTP web agent allows you to configure switch parameters, monitor port connections, and display statistics using a standard web browser such as Netscape version 6.2 and higher or Microsoft IE version

5.0 and higher. The switch’s web management interface can be accessed from any computer attached to the network.

“Setting an IP Address” on page 2-6.

The CLI program can be accessed by a direct connection to the RS-232 serial console port on the switch, or remotely by a Telnet connection over the network.

The switch’s management agent also supports SNMP (Simple Network Management Protocol). This SNMP agent permits the switch to be managed from any system in the network using network management software such as HP OpenView.

NITIAL CONFIGURATION

Remote Connections

Prior to accessing the switch’s onboard agent via a network connection, you must first configure it with a valid IP address, subnet mask, and default gateway using a console connection, DHCP or BOOTP protocol.

The IP address for this switch is obtained via DHCP by default. To manually configure this address or enable dynamic address assignment via DHCP or BOOTP, see “Setting an IP Address” on page 2-6.

Note: This switch supports four concurrent Telnet/SSH sessions.

After configuring the switch’s IP parameters, you can access the onboard configuration program from anywhere within the attached network. The onboard configuration program can be accessed using Telnet from any computer attached to the network. The switch can also be managed by any computer using a web browser (Internet Explorer 5.0 or above, or Netscape 6.2 or above), or from a network computer using SNMP network management software.

Note: The onboard program only provides access to basic configuration

functions. To access the full range of SNMP management functions, you must use SNMP-based network management software.

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.

2-4

Page 45

ASIC CONFIGURATION

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 Username 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

Note: 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 8 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>.

2-5

CLI session with the SMC6128PL2 is opened. To end the CLI session, enter [Exit].

Console#configure Console(config)#username guest password 0 [password] Console(config)#username admin password 0 [password] Console(config)#

Setting an IP Address

You must establish IP address information for the stack 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 stack’s master unit, you will also need to specify the default gateway router.

Dynamic — The switch sends IP configuration requests to BOOTP or DHCP address allocation servers on the network.

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 IP addresses consist of four decimal numbers, 0 to 255, separated by periods. Anything outside this format will not be accepted by the CLI program.

Note: The IP address for this switch is obtained via DHCP by default.

Before you can assign an IP address to the switch, you must obtain the following information from your network administrator:

2-6

Page 47

ASIC CONFIGURATION

• IP address for the switch

• Default gateway for the network

• Network mask for this network

To assign an IP address to the switch, complete the following steps:

1. From the Privileged Exec level 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>.

Console(config)#interface vlan 1 Console(config-if)#ip address 192.168.1.5 255.255.255.0 Console(config-if)#exit Console(config)#ip default-gateway 192.168.1.254 Console(config)#

Dynamic Configuration

If you select the “bootp” or “dhcp” option, IP will be enabled but will not function until a BOOTP or DHCP reply has been received. You therefore need to use the “ip dhcp restart” command to start broadcasting service requests. Requests will be sent periodically in an effort to obtain IP configuration information. (BOOTP and DHCP values can include the IP address, subnet mask, and default gateway.)

2-7

Page 48

NITIAL CONFIGURATION

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>.

4. Type “ip dhcp restart” to begin broadcasting service requests. Press

<Enter>.

5. Wait a few minutes, and then check the IP configuration settings by typing the “show ip interface” command. Press <Enter>.

2-8

6. Then save your configuration changes by typing “copy running-config startup-config.” Enter the startup file name and press <Enter>.

Console(config)#interface vlan 1 Console(config-if)#ip address dhcp Console(config-if)#end Console#ip dhcp restart Console#show ip interface IP address and netmask: 192.168.1.54 255.255.255.0 on VLAN 1, and address mode: User specified. Console#copy running-config startup-config Startup configuration file name []: startup \Write to FLASH Programming.

\Write to FLASH finish. Success.

Enabling SNMP Management Access

The switch can be configured to accept management commands from Simple Network Management Protocol (SNMP) applications such as HP OpenView. You can configure the switch to (1) respond to SNMP requests or (2) 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 page 3-63).

2-9

Page 50

NITIAL CONFIGURATION

Community Strings (for SNMP version 1 and 2c clients)

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 4-139 Console(config)#snmp-server community private Console(config)#

Note: 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.

2-10

Page 51

ASIC CONFIGURATION

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, “community-string” 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 4-141. The following example creates a trap host for each type of SNMP client.

Console(config)#snmp-server host 10.1.19.23 batman 4-141 Console(config)#snmp-server host 10.1.19.98 robin version 2c Console(config)#snmp-server host 10.1.19.34 barbie version 3 auth Console(config)#

Configuring Access for 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

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 3-47, or refer to the specific CLI commands for SNMP starting on page 4-136.

Saving Configuration Settings

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.

To save the current configuration settings, enter the following command:

1. From the Privileged Exec mode prompt, type “copy running-config

startup-config” and press <Enter>.

2. Enter the name of the start-up file. Press <Enter>.

Console#copy running-config startup-config Startup configuration file name []: startup \Write to FLASH Programming.

ANAGING SYSTEM FILES

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 three types of files are:

• Configuration — This file 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 TFTP to a server for backup. A file named “Factory_Default_Config.cfg” contains all the system default settings and cannot be deleted from the system. See “Saving or Restoring Configuration Settings” on page 3-27 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 Firmware” on page 3-24 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.

In the system flash memory, one file of each type must be set as the start-up 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.

2-13

Page 54

NITIAL CONFIGURATION

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.

Using the Web Interface

This switch provides an embedded HTTP web agent. Using a web browser you can configure the switch and view statistics to monitor network activity. The web agent can be accessed by any computer on the network using a standard web browser (Internet Explorer 5.0 or above, or Netscape

6.2 or above).

Note: You can also use the Command Line Interface (CLI) to manage

the switch over a serial connection to the console port or via Telnet. For more information on using the CLI, refer to “Command Line Interface.”

Prior to accessing the switch from a web browser, be sure you have first performed the following tasks:

1.Configure the switch with a valid IP address, subnet mask, and default

gateway using an out-of-band serial connection, BOOTP or DHCP protocol. (See

2. Set user names and passwords using an out-of-band serial connection.

Access to the web agent is controlled by the same user names and passwords as the onboard configuration program. (See Passwords” on page 2-5.)

3. After you enter a user name and password, you will have access to the

system configuration program.

Displaying Bridge Extension Capabilities

The Bridge MIB includes extensions for managed devices that support Multicast Filtering, Traffic Classes, and Virtual LANs. You can access these extensions to display default settings for the key variables.

Field Attributes

• Extended Multicast Filtering Services – This switch does not support the filtering of individual multicast addresses based on GMRP (GARP Multicast Registration Protocol).

• Traffic Classes – This switch provides mapping of user priorities to multiple traffic classes. (Refer to “Class of Service Configuration” on page 3-204.)

• Static Entry Individual Port – This switch allows static filtering for unicast and multicast addresses. (Refer to “Setting Static Addresses” on page 3-145.)

• VLAN Learning – This switch uses Shared VLAN Learning (SVL), where all VLANs share the same address table.

• Configurable PVID Tagging – This switch allows you to override the default Port VLAN ID (PVID used in frame tags) and egress status (VLAN-Tagged or Untagged) on each port. (Refer to “VLAN Configuration” on page 3-175.)

• Local VLAN Capable – This switch does not support multiple local bridges outside of the scope of 802.1Q defined VLANs.

• GMRP – GARP Multicast Registration Protocol (GMRP) allows network devices to register endstations with multicast groups. This switch does not support GMRP; it uses the Internet Group Management Protocol (IGMP) to provide automatic multicast filtering.

Setting the Switch’s IP Address

This section describes how to configure an IP interface for management access over the network. The IP address for the stack is obtained via DHCP by default. To manually configure an address, you need to change the switch’s default settings (IP address 192.168.1.1 and netmask

255.255.255.0) to values that are compatible with your network. You may also need to a establish a default gateway between the stack and management stations that exist on another network segment.

3-19

Page 74

ONFIGURING THE SWITCH

You can manually configure a specific IP address, or direct the device to obtain an address from a BOOTP or DHCP server. Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods. Anything outside this format will not be accepted by the CLI program.

Command Attributes

• Management VLAN – ID of the configured VLAN (1-4094, no leading zeroes). By default, all ports on the switch are members of VLAN 1. However, the management station can be attached to a port belonging to any VLAN, as long as that VLAN has been assigned an IP address.

• IP Address Mode – Specifies whether IP functionality is enabled via manual configuration (Static), Dynamic Host Configuration Protocol (DHCP), or Boot Protocol (BOOTP). If DHCP/BOOTP is enabled, IP will not function until a reply has been received from the server. Requests will be broadcast periodically by the switch for an IP address. (DHCP/BOOTP values can include the IP address, subnet mask, and default gateway.)

• IP Address – Address of the VLAN interface that is allowed management access. Valid IP addresses consist of four numbers, 0 to 255, separated by periods. (Default: 0.0.0.0)

• Subnet Mask – This mask identifies the host address bits used for routing to specific subnets. (Default: 255.0.0.0)

• Gateway IP address – IP address of the gateway router between this device and management stations that exist on other network segments. (Default: 0.0.0.0)

• MAC Address – The physical layer address for this switch.

• Restart DHCP – Requests a new IP address from the DHCP server.

Renewing DCHP – DHCP may lease addresses to clients indefinitely or for a specific period of time. If the address expires or the switch is moved to another network segment, you will lose management access to the switch. In this case, you can reboot the switch or submit a client request to restart DHCP service via the CLI.

Web – If the address assigned by DHCP is no longer functioning, you will not be able to renew the IP settings via the web interface. You can only restart DHCP service via the web interface if the current address is still available.

Configuring Event Logging

The switch allows you to control the logging of error messages, including the type of events that are recorded in switch memory, logging to a remote System Log (syslog) server, and displays a list of recent event messages.

Displaying Log Messages

The Logs page allows you to scroll through the logged system and event messages. The switch can store up to 2048 log entries in temporary random access memory (RAM; i.e., memory flushed on power reset) and up to 4096 entries in permanent flash memory.

Web – Click System, Log, Logs.

System Log Configuration

The system allows you to enable or disable event logging, and specify which levels are logged to RAM or flash memory.

Severe error messages that are logged to flash memory are permanently stored in the switch to assist in troubleshooting network problems. Up to 4096 log entries can be stored in the flash memory, with the oldest entries being overwritten first when the available log memory (256 kilobytes) has been exceeded.

The System Logs page allows you to configure and limit system messages that are logged to flash or RAM memory. The default is for event levels 0 to 3 to be logged to flash and levels 0 to 6 to be logged to RAM.

Command Attributes

• System Log Status – Enables/disables the logging of debug or error messages to the logging process. (Default: Enabled)

ONFIGURING THE SWITCH

Setting the System Clock

Simple Network Time Protocol (SNTP) allows the switch to set its internal clock based on periodic updates from a time server (SNTP or NTP). Maintaining an accurate time on the switch enables the system log to record meaningful dates and times for event entries. You can also manually set the clock using the CLI. (See “calendar set” on page 4-78.) If the clock is not set, the switch will only record the time from the factory default set at the last bootup.

When the SNTP client is enabled, the switch periodically sends a request for a time update to a configured time server. You can configure up to three time server IP addresses. The switch will attempt to poll each server in the configured sequence.

Configuring SNTP

You can configure the switch to send time synchronization requests to time servers.

Command Attributes

• SNTP Client – Configures the switch to operate as an SNTP client. This requires at least one time server to be specified in the SNTP Server field. (Default: Disabled)

• SNTP Broadcast Client – Configures the switch to operate as an SNTP broadcast client. This mode requires no other configuration settings; the switch will obtain time updates from time server broadcasts (using the multicast address 224.0.1.1).

• SNTP Poll Interval – Sets the interval between sending requests for a time update from a time server. (Range: 16-16384 seconds; Default: 16 seconds)

• SNTP Server – Sets the IP address for up to three time servers. The switch attempts to update the time from the first server, if this fails it attempts an update from the next server in the sequence.

Setting the Time Zone

SNTP uses Coordinated Universal Time (or UTC, formerly Greenwich Mean Time, or GMT) based on the time at the Earth’s prime meridian, zero degrees longitude. To display a time corresponding to your local time, you must indicate the number of hours and minutes your time zone is east (before) or west (after) of UTC.

Command Attributes

• Current Time – Displays the current time.

• Name – Assigns a name to the time zone. (Range: 1-29 characters)

• Hours (0-12) – The number of hours before/after UTC.

• Minutes (0-59) – The number of minutes before/after UTC.

• Direction – Configures the time zone to be before (east) or after (west) UTC.

Web – Select SNTP, Clock Time Zone. Set the offset for your time zone relative to the UTC, and click Apply.
