2. Web-based Switch Configuration

Management Options Logging into the Web UI Web User Interface (Web UI)

Management Options

The Switch provides multiple access platform s that can be used to configure, manage, and moni tor networking features available on this Switch. Current l y there are three management platforms available which are described below.

Command Line Interface (CLI)

The Switch can be managed, out-of-band, by using the console port or the MGMT port on the front panel of the Switch. Alternatively, the Switch can also be managed, in-band, by using a Telnet connection to any o f the LAN ports on the Switch. The command line interface provi des complete access to all Switch management features.

For more detailed information about the CLI, refer to the DXS-3400 Series CLI Reference Guide.

SNMP-based Management

The Switch can be managed with an SNMP-compatible console program. The Switch supports S NM P v1/v2c/v3. The SNMP agent decodes the incoming SNMP messages and responds to requests with MIB objects stored in the database. The SNMP agent updates the MIB object s to generate statistics and counters.

Web User Interface (Web UI)

The Web UI can be accessed from any computer run ning web browsing software from its MGMT port or LAN port when it is connected to any of the RJ45 or SFP/SFP + ports. The Web UI on the Switch can also be accessed using an HTTPS (SSL) connection.

This management interface is a more graphical representation of the features that can be vie wed and configured on the Switch. Most of the features available t hrough the CLI can be accessed through the Web UI . Web browsers like Microsoft’s Internet Explorer, Mozilla Fir efox, or Google Chrome can be used.

NOTE: The Command Line Interface (CLI) provides the functionality of m anagi ng, configuring, and

monitoring all of the software features that are availabl e on the Switch.

Logging into the Web UI

To access the Web UI open a standard web browser and ent er the IP address of the Switch into the address bar of the browser and press the ENTER key.

NOTE: The default IP address of the Switch is 10.90.90.90, with a subnet mask of 255.0.0.0.

Figure 2-1 Displays entering the IP address in Internet Explorer

Figure 2-2 Web UI Login Window

When connecting to the Web UI of the Switch for the first time, leave the User Name and Password fields blank and click Login since there are no login user accounts creat ed by default on the Switch.

NOTE: After a user account was created, login credentials will be required t o access the Web UI.

During the sending and receiving of the login password to and from the Switch, this information will be protected using a strong encryption algorithm to prevent attackers from snooping thi s information to gain unauthorized access to t he Switch.

Web User Interface (Web UI)

The Web UI provides access to various Switch configuration and management windows. It all ows the user to view performance statistics, and permits graphical monitoring of the system’s status.

SNMP

Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) desi gned specifically for managing and monitoring network devices. S NMP enables network management stations to read and modify the settings of gateways, routers, switches, and other network devices. Use SNMP to configure system features for proper operation, monitor performance and detect potential problems in the Switch, switch group or network.

Managed devices that support SNMP include software (referred to as an agent), which runs locally on t he device. A defined set of variables (managed objects) is mai ntained by the SNMP agent and used to manage the de vice. These objects are defined in a Management Inform ation Base (MIB), which provides a standard p resentation of the information controlled by the on-board SNMP agent. SNMP defines both the format of the MIB specif ications and the protocol used to access this information over t he network.

The Switch supports the SNMP versions 1, 2c, and 3. The three versions of SNMP vary in the level of sec urity provided between the management station and the network device.

In SNMPv1 and SNMPv2c, user authentication is accomplished using ‘community strings’, which function li ke passwords. The remote user SNMP application and the Switch SNMP must use the same community string. SNMP packets from any station that has not been aut henticated are ignored (dropped).

The default community strings for the Switch used for SNMPv1 and SNMPv2c management access are:

• public - Allows authorized management stations to retrieve MIB objects.

• private - Allows authorized management stations to retrieve and modify MIB objects.

SNMPv3 uses a more sophisticated authentic ation process that is separated into two parts. The fi rst part is to maintain a list of users and their attributes that are allowed to act as SNMP managers. The second part describes what each user on that list can do as an SNMP mana ger.

The Switch allows groups of users to be listed and configured with a shared set of privileges. The SNMP version may also be set for a listed group of SNMP managers. T hus, you may create a group of SNMP managers that are allowed to view read-only information or receive traps using SNMPv1 while assigning a higher level of security to another group, granting read/write privileges using S NMPv3.

Using SNMPv3 individual users or groups of SNMP managers can be allowed to perform or be re st ricted from performing specific SNMP management funct i ons. The functions allowed or restricted are def i ned using the Object Identifier (OID) associated with a specific MIB. An additional layer of security is avail abl e for SNMPv3 in that SNMP messages may be encrypted. To read more about how to configure SNMPv3 settings for the Switch read the next section.

Traps

Page 42

DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide

Traps are messages that alert network personnel of events that occur on the Switch. The events ca n be as serious as a reboot (someone accidentally turned OFF the Switch), or less serious like a port status change. T he Switch generates traps and sends them to the trap recipient (or network manager). Typical traps include trap messages for Authentication Failure, Topology Change and Broadcast\Multicast Storm.

MIBs

The Switch in the Management Information B ase (MIB) stores management and counter informati on. The Switch uses the standard MIB-II Management Information Base m odul e. Consequently, values for MIB objects can b e retrieved from any SNMP-based network management sof tware. In addition to the standard MIB-II, the Switch also supports its own proprietary enterprise MIB as an extended Management Information Base. Specifying the M IB Object Identifier may also retrieve the proprietary MIB. M IB values can be either read-only or read-write.

The Switch incorporates a flexible SNMP m anagement for the Switching environment. SNMP management can be customized to suit the needs of the networks and the preferences of the network administrator. Use the SNMPv3 menus to select the SNMP version used for specif ic tasks.

The administrator can specify the SNMP version us ed to monitor and control the Switch. The three versions of SNMP vary in the level of security provided between the m anagement station and the network device.

SNMP settings are configured using the menu s located on the SNMP V3 folder of the Web manager. Workstations on the network that are allowed SNMP privileged acces s t o the Switch can be restricted with the Manageme nt Station IP Address menu.

DHCP Server

DHCP, or Dynamic Host Configuration P rot ocol, allows the Switch to delegate IP addresses, subnet masks, default gateways and other IP parameters to devices that request this information. This occurs when a DH CP enabled device is booted on or attached to the locally attach ed network. This device is known as the DHCP client and when enabled, it will emit query messages on the network bef ore any IP parameters are set. When the DHCP server receives this request, it will allocate an IP address to the client. The DHCP client may be then utilize the IP address allocated by the DHCP server as its local configuration.

The user can configure many DHCP related para m eters that it will utilize on its locally attach ed network, to control and limit the IP settings of clients desiring an automatic IP configuration, such as the lease time of the allotted IP address, the range of IP addresses that will be allowed in i ts DHCP pool, the ability to exclude various IP addres ses within the pool so as not to make identical entries on its network, or to assign the IP address of an important device (such as a DNS server or the IP address of the default route) to another device on the network.

Users also have the ability to bind IP addresses within the DHCP pool to specific MAC addresses in order to keep consistent the IP addresses of devices that m ay be important to the upkeep of the network that require a static IP address.

Parameter Description

Profile Name

Format String

Enter the Option 82 profile name here. The profile can be used to define the flexible user-defined Option 82 entry.

After clicking the Edit button, enter the user-defined DHCP Option 82 format string here. This string can be up to 251 characters long.

The following rules need to be considered:

• This string can be a hexadecimal value, an ASCII string, or any combination of hexadecimal values and ASCII character s. An ASCII string needs to be enclosed with quotation marks (“”) like “Ethernet”. Any ASCII characters outside of the quotation marks will be interpreted as hexadecimal values.

• A formatted key string is a string that should be translated before being encapsulated in the packet. A formatted key string can be contained both ASCII strings and hexadecimal values. For ex am ple, “%” +“$”+“1~32”+ “keyword”+ “:”:

○ % - Indicates that the string that follows this character i s a formatted

key string.

○ “$” or “0” - (Optional) Indicates a fill indicator. This option specifies

how to fill the formatted key string to meet t he l ength option. This option can be either “$” or “0”, and cannot be specified as both at the same time.

 “$” - Indicates to fill the leading space (0x20).  “0” - Indicates to fill the leading 0. The fill the leading 0 (0) is the

default setting.

○ 1~32 - (Optional) Indicates a length option. This specifies how many

characters or bytes the translated key string should occupy. If the actual length of the translated key string i s less than the length specified by this option, a fill indicator will be used to fill. Otherwise, this length option and fill indicator will be ignored and the actual string will be used directly.

○ keyword - Indicates that the keyword will be translated based on the

actual value of the system. The following keyword definitions specifies that a command will be refused if an unknown or un supported keyword is detected:

 devtype - The model name of the device. Only an ASCII string is

allowed.

 sysname - Indicates the System name of the S witch. Only an

ASCII string is allowed.

 ifdescr - Derived from ifDescr (IF-MIB). Only an ASCII string is

allowed.

 portmac - Indicates the MAC address of a port. Thi s can be either

an ASCII string or a hexadecimal value. Whe n i n the format of an ASCII string, the MAC address format can be customized using special CLI commands. When in the format of a hexadecimal value, the MAC address will be encapsulated by order in hexadecimal.

 sysmac - Indicates the system MAC address. T his can be either

an ASCII string or a hexadecimal value. In the ASCII string format, the MAC address format can be customized using special CLI commands. In the hexadecimal format, the M AC address will be encapsulated by order in hexadecimal.

 unit - Indicates the unit ID. This can be either an A SCII string or a

hexadecimal value. For a standalone device, t he uni t ID is 0.

 module - Indicates the module ID number. This can be either an

ASCII string or a hexadecimal value.

string or a hexadecimal value.

Parameter Description

 svlan - Indicates the outer VLAN ID. This can be ei ther an ASCII

string or a hexadecimal value.

 cvlan - Indicates the inner VLAN ID. This can be either an ASCII

string or a hexadecimal value.

○ : - Indicates the end of the formatted key st ing. If a formatted key string

is the last parameter of the command, its endi ng character (“:”) can be ignored. The space (0x20) between “%” and “:” wil l be ignored. Other spaces will be encapsulated.

• ASCII strings can be any combination of formatted key strings and 0~9, a~z, A~Z, !@#$%^&*()_+|-=\[]{};:'"/?.,<>`, and space characters. “\” is the escape character. The special character after “\” is t he character itself, for example, “\%” is “%” itself, not the start indicator of a formatted key string. Spaces not in the formatted key string will also be encapsulated.

• Hexadecimal values can be any combination of formatted key strings and 0~9, A~F, a~f, and space characters. The formatted key strings only support keywords that support hexadecimal values. Spaces not in the formatted key string will be ignored.

DNS

Computer users usually prefer to use text nam es f or computers for which they may want to open a connection. Computers themselves, require 32 bit IP addresses. Somewhere, a database of network devices’ text names and their corresponding IP addresses must be maintaine d.

The Domain Name System (DNS) is used to map names to I P addresses throughout the Internet and has been adapted for use within intranets. For two DNS serv ers to communicate across different subnet s, the DNS Relay of the Switch must be used. The DNS servers are identified by IP addresses.

Mapping Domain Names to Addresses

Name-to-address translation is performed by a program called a Name server. The client program is called a Name resolver. A Name resolver may need to contact several Name servers to translate a name to an address.

The Domain Name System (DNS) servers are organized in a somewhat hierarchical fashion. A single server often holds names for a single network, which is connected to a root DNS server - usually maintained by an IS P .

Domain Name Resolution

The domain name system can be used by contact ing the name servers one at a time, or by asking the d omain name system to do the complete name translation. The cli ent makes a query containing the name, the t ype of answer required, and a code specifying whether the domain name system should do the entire name translati on, or simply return the address of the next DNS server if the serv er receiving the query cannot resolve the name.

When a DNS server receives a query, it checks to see if the name is in its sub domain. If it is, the server translat es the name and appends the answer to the query, and sends it back to the client. If the DNS server cannot translate the

Page 80

DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide

name, it determines what type of name resoluti on the client requested. A complete translat i on is called recursive resolution and requires the server to contact other DNS servers until the name is resolved. Iterative resolution specifies that if the DNS server cannot supply an answer, it returns the address of the next DNS server the client should contact.

Each client must be able to contact at least one DNS server, and each DNS server must be able to contact at least one root server.

The address of the machine that supplies domain name service is often supplied by a DHCP or BOOTP server, or can be entered manually and configured into the operat i ng system at startup.

Stacking

The Switch supports stacking 4 Switches together while being man aged by one console connection to any one of the console ports on the master Switch, or by an IP address th rough the MGMT port, or by multiple IP addresses through any of the RJ45/SFP+ ports using Telnet, the Web User Interface, and SNMP. This cost effect ive Switch provides an affordable solution for administrators to upgrade their networks using the combo RJ45/SFP+ ports t o scale and stack the Switches. This increases overall reliability, serviceability, and availability.

• Duplex Chain – The Duplex Chain topology stacks Switches together i n a chain-link format. Using this method, data transfer is only possible in one direction and i f there is a break in the chain, then data transf er will obviously be affected.

• Duplex Ring – The Duplex Ring stacks Switches in a ring or circle format where data can be transferred in two directions. This topology is very resilient due to the fact that if there is a break in the ring, data can still be transferred through the stacking cables between Switches in the stack.

Page 92

DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide

Switches in the series can be physically stacked using standard Category 6a cables with RJ45 con nectors, optical fiber cables connected to SFP+ transceivers, or Direct Attached Cables (DAC) with SFP + c onnectors. Only the last 4 ports can be used for physical stacking.

Physical stacking needs to be enabled and can be c onfigured to support either a 2-port or a 4-port stacking configuration. When the 2-port stacking configuration is used, a full-duplex speed of up to 40Gbps will be used between two Switches. When the 4-port stacking configuration is used, a full-duplex speed of up to 80Gbps will be used between two Switches.

Figure 4-78 Duplex Ring stacking topology (SFP+)

NOTE: SIO1 is a logical stacking port pair. SIO2 is also a logical stacking port pair. A logical stacking

port pair must always be connected to the same Switch in the stack. Splitting logical stacking port pairs between different Switches in the stack might not guarantee a stable stacking connection.

Within each of these topologies, each Switch plays a role in the Switch stack. These roles can be set by the user per individual Switch, or if desired, can be autom atically determined by the Switch stack. Three pos sibl e roles exist when stacking with the Switch.

Primary Master - The Primary Master is t he l eader of the stack. It will maintain normal operations, monitor operations and the running topology of the Stack. The Switch will also assign Stack Unit IDs, synchronize configurations and transmit commands to remaining Switches in the Switch stack. The Primary Master can be manually set by assigning

Page 94

DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide

this Switch the highest priority (a lower numbe r denotes a higher priority) before physically assembling the stack, or it can be determined automatically by the stack t hrough an election process which determine s t he lowest MAC address and then will assign that Switch as the Primary Master, if al l priorities are the same. The Primary master are phy sically displayed by the seven segment LED to the far left on the front panel of the Switch where this LED will flash between its given Box ID and ‘H’.

Backup Master - The Backup Master is the backup to the Primary Master, and will take over the funct i ons of the Primary Master if the Primary Master fails or is removed from the Stack. It also monitors the status of neighboring Switches in the stack, will perform commands assigned to it by the Primary Master and will monitor the running st atus of the Primary Master. The Backup Master can be set by the user by assigning this Switch the second highest priority before physically assembling the stack, or i t can be determined automatically by the stack through an election process which determines the second lowest MAC address and then will assign that Switch as the Backup Master, if all priorities are the same. The Backup master are physically displayed by the seven segment LED to t he far left on the front panel of the Switch where this LED will flash between its give n Box ID and ‘h’.

Slave - Slave Switches constitute the rest of the Switch stack and although not Primary or Backup Mast ers, they can be placed into these roles when these other two r ol es fail or are removed from the stack. Slav e Switches perform operations requested by the master, monitor the status of neighbor Switches in the stack and the stack topology and adhere to the Backup Master’s commands once it becomes a Primary Master. Slave Switches will do a self-check to determine if it is to become the Backup Master if the Backup Master is promoted to the Primary M ast er, or if the Backup Master fails or is removed from the Switch stack. If both Primary and Backup masters fail, or are removed from the Switch stack, it will determine if it is to become the Primary Master. These roles will be determined, first by priority and if the priority is the same, the lowest MAC address.

Once Switches have been assembled in the topology desired by the user and powered on, the stack will undergo three processes until it reaches a functioning stat e.

• Initialization State - This is the first state of the stack, where the runtime codes are set and initialized and the system conducts a peripheral diagnosis to det erm ine each individual Switch is functioning properly.

• Master Election State - Once the codes are loaded and i nitialized, the stack will undergo the Maste r E l ect ion State where it will discover the type of topology used, elect a Primary Master and then a Backup M ast er.

• Synchronization State - Once the Primary Master and the Backup Master have been established, the Primary Master will assign Stacking Unit IDs to Switches in the stack, synchronize configurations for all Switches and then transmit commands to the rest of the Switches based on the users conf i gurations of the Primary Master.

Once these steps have been completed, the Switch stack will enter a norm al operating mode.

Stack Switch Swapping

The stacking feature of the Switch supports “ hot swapping” of Switches in and out of the running stack. Users may remove or add Switches to the stack without powering down or largely affecting the transfer of data between Switches in the stack, with a few minor provisions.

When Switches are “hot inserted” into the running stack, the new Switch may take on the Primary Master, Backup Master or Slave role, depending on configurations set on the newly added Switch, such as configured priority or MAC address. Yet, if adding two stacks together that have both previously undergone the election p roc ess, and therefore both have a Primary Master and a Backup master, a new Primary Master will be elected from one of t he al ready existing Primary Masters, based on priority or MAC address. This Primary Master will take over all of the Primary Master’s roles for all new Switches that were hot inserted. This process is done using discovery packets that circulate through the Switch stack every 1.5 seconds until the discovery process has been completed.

The “hot remove” action means removing a device from the stack while the stack is still running . The hot removal is detected by the stack when it fails to receive he art beat packets during its specified interval from a device, or when one of the stacking ports links is down. Once the dev i ce has been removed, the remaining Switches will update their stacking topology database to reflect the cha nge. Any one of the three roles, Primary Master, Backup Master or Slave, may be removed from the stack, yet different pro cesses occur for each specific device removal.

If a Slave device has been removed, the Primary M aster will inform other Switches of the hot remove of this device through the use of unit leave messages. Switches in the stack will clear the configurations of the unit removed, and dynamically learned databases, such as A RP , will be cleared as well.

If the Backup Master has been hot removed, a new Backup Master will be chosen through the elect i on process previously described. Switches in the stack will clear the configurations of the unit removed, and dynamically learned databases, such as ARP, will be cleared as well. Then the Backup Master will begin backing up the Prim ary Master when the database synchronization has been completed by the stack.

If the Primary Master is removed, the Backup Master will assume the Primary Master’s role and a new Backup Master will be chosen using the election process. Switches in the stack will clear the configurations of the unit removed, and

Page 95

DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide

dynamically learned databases, such as A RP , will be cleared as well. The new Primary Master will inherit the MAC and IP address of the previous Primary M ast er to avoid conflict within the stack and the network itself.

If both the Primary Master and the Backup Mast er are removed, the election process is immediately processed, and a new Primary Master and Backup Master are determined. Switches in the stack will clear the configurations of the units removed, and dynamically learned databases, such as ARP, will be cleared as well. Stati c Switch configurati ons still remain in the database of the remaining Switches in the stack and those functions will not be affected.

NOTE: If there is a Box ID conflict when the stack is in the discovery phase, the device will enter a

special standalone topology mode. Users can only get device information, configure Box IDs, save and reboot. All stacking ports will be disabled and an error message will be produced on the local console port of each device in the stack. Users must reconfigure Box IDs and reboot the stack.

Stacking Bandwidth

This window is used to display and configure the stacking bandwidth settings. Physical stackin g needs to be enabled and can be configured to support either a 2-port or a 4-port stacking configuration.

• When the 2-port stacking configuration is used, a full-duplex speed of up to 40Gbps will be used betw een two Switches using the physical ports 23 and 24. Port 23 will act as S IO1 and port 24 will act as SIO2.

• When the 4-port stacking configuration is used, a full-duplex speed of up to 80Gbps will be used betw een two Switches using ports 21 to 24 aggregated into two virtual stacking ports. Ports 21 and 23 will act as SIO1 and ports 22 and 24 will act as SIO2.

SIO1 is a logical stacking port pair and SIO2 is a logical stacking port pair. A logical stacking port pair must always be connected to the same Switch in the stack. Splitt i ng logi cal stacking port pairs between different Switches in the stack might not guarantee a stable stacking connecti on.

The stacking bandwidth must be configured before the Switch is stacked with other Switches.

Virtual Stacking (SIM)

D-Link Single IP Management (SIM) is a concept that will stack Switches together over Ethernet instead of using stacking ports or modules. There are some advantages in implementing the Single IP Management feature:

Page 97

DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide

• SIM can simplify management of small workgroups or wiring closets while scaling the networ k to handle increased bandwidth demand.

• SIM can reduce the number of IP address needed i n your network.

• SIM can eliminate any specialized cables for stacking connectivity and remove the distance barriers that

typically limit your topology options when using other stacking technology.

Switches using D-Link Single IP Management (labeled here as SIM) must conform to the following rules:

• SIM is an optional feature on the Switch and can easily be enabled or disabled through the Command Line Interface or Web Interface. SIM grouping has no effect on the normal operation of the Swit ch in the user’s network.

• There are three classifications for Switches using SIM. The Commander Switch (CS), whic h i s t he m aster Switch of the group, Member Switch (MS), which is a Switch that is recognized by the CS a member of a S IM group, and a Candidate Switch (CaS), which is a S witch that has a physical link to the SIM group but has not been recognized by the CS as a member of the SIM group.

• A SIM group can only have one Commander Switch (CS).

• A SIM group accepts up to 32 Switches (numbered 1-32), not including the Commander Switch (numbered 0).

• Members of a SIM group cannot cross a router.

• There is no limit to the number of SIM groups in the same IP subnet (broadcast domain); however a single

Switch can only belong to one group.

• If multiple VLANs are configured, the SI M group will only utilize the management VLAN on any Switch.

• SIM allows intermediate devices that do not sup port SIM. This enables the user to manage Switches that are

more than one hop away from the CS.

The SIM group is a group of Switches that are managed as a single ent i ty. The Switch may take on three different roles:

1. Commander Switch (CS) - This is a Switch that has been manually configured as the controlling device for a group, and takes on the following charact erist i cs:

 It has an IP Address.  It is not a command Switch or member Switch of another Single IP group.  It is connected to the member Switches through its management VLAN.

2. Member Switch (MS) - This is a Switch that has joined a single IP group and is accessible from the CS, and it takes on the following characteristics:

 It is not a CS or MS of another IP group.  It is connected to the CS through the CS management VLAN.

3. Candidate Switch (CaS) - This is a Switch that is ready to join a S IM group but is not yet a member of the SIM group. The Candidate Switch may join the SIM group of the Switch by manually configuring it to be a M S of a SIM group. A Switch configured as a CaS is not a member of a SIM group and will take on the following characteristics:

 It is not a CS or MS of another Single IP group.  It is connected to the CS through the CS management VLAN

The following rules also apply to the above roles:

• Each device begins in a Candidate state.

• A CS must change its role to CaS and then to MS, t o become a MS of a SIM group. Thus, the CS cannot

directly be converted to a MS.

• The user can manually configure a CS to become a CaS.

• A MS can become a CaS by:

 Being configured as a CaS through the CS.  If report packets from the CS to the MS time out.

• The user can manually configure a CaS to become a CS

Page 98

DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide

• The CaS can be configured through the CS to become a MS.

After configuring one Switch to operate as the CS of a SIM group, additional Switches may join the group b y manually configuring the Switch to be a MS. The CS will then s erve as the in band entry point for access to the MS. The CS’s IP address will become the path to all MS’s of the group and the CS’s Administrator’s password, and/or authe ntication will control access to all MS’s of the SIM group.

With SIM enabled, the applications in the CS wil l redirect the packet instead of executing the packets. The applications will decode the packet from the adm ini strator, modify some data, and then send it t o the MS. After execution, the CS may receive a response pac ket from the MS, which it will encode and send it back to the administrator.

When a CaS becomes a MS, it automatically becomes a member of the first SNMP community (includes read/writ e and read only) to which the CS belongs. However, if a MS has its own IP address, it can belong to SNMP communities to which other Switches in the group, including the CS, do not belong.

Upgrade to v1.61

To better improve SIM management, the Switches have been upg raded to version 1.61 in this release. Many improvements have been made, including the Commander Switch (CS) now has the capability to automatically rediscover member Switches that have left the SIM group, ei ther through a reboot or web malfunction. This f eature is accomplished through the use of Discover pack ets and Maintenance packets that previously set S IM members will emit after a reboot. Once a MS has had its MAC address and password saved to the CS’s database, i f a reboot occurs in the MS, the CS will keep this MS inform ation in its database and when a MS has been rediscov ered, it will add the MS back into the SIM tree automatically. No configuration will be necessary to rediscover these Switches.

There are some instances where pre-saved MS Switches cannot b e rediscovered. For example, if the Switch is still powered down, if it has become the member of another group, or if it has been configured to be a Commander Switch, the rediscovery process cannot occur.

The topology map now includes new features fo r connections that are a member of a port trunking group. It will display the speed and number of Ethernet connecti ons creating this port trunk group, as shown in the adjacent picture.

This version will support Switch upload and downloads for firmware, configuration files and log files, as follows:

• Firmware - The Switch now supports MS firmware downl oads from a TFTP server.

• Configuration Files - The Switch now supports downloading and uploading of configuration files both to (for

configuration restoration) and from (for configuration backup) MS’s, using a TFTP server.

• Log - The Switch now supports uploading MS log files to a TFTP server.

The user may zoom in and zoom out when utilizing the t opol ogy window to get a better, more defined view of the configurations.
