Introduction

What Is in This ChapterThis chapter describes the SPECTRUM Management Module for the NAT EtherMeter devices. It also provides the model type names assigned to the NAT EtherMeter devices in SPECTRUM. The model type name refers to the template used to specify device attributes, actions, and associations for device models in SPECTRUM.

NAT EtherMeter Management ModuleThe NAT EtherMeter is a network device that collects statistics on the Ethernet network. The EtherMeters are polled through the network, and through intermediate bridges, routers, or concentrators. SPECTRUM’s network monitoring functions work with the EtherMeter to control and collect statictics, displaying the results in tables and in graphs.

Modem Configuration View

You can access the Modem Configuration view by clicking on the Modem Configuration button in the NAT EtherMeter Device Configuration view. If the NAT EtherMeter is being accessed via the serial port (using a Hayes-compatible asynchronous mode), this view displays the following configuration information for the modem:

Hayes command string for modem initializationDisplays the default string that initializes the modem for proper operation. The following should be part of the configuration string: ‘e0v1q0&c1&d2’. If error correction and RTS/CTS flow control are provided by the modem, the string should also include commands for error and flow control. The initialization string can be up to 40 characters in length.

Dial PrefixDisplays the dialing prefix to be used. For touch tone dialing, this is ‘atdt’; for pulse tone dialing, use ‘atdp’. You can update this field.

Dial SuffixDisplays the dialing suffix to be used. Usually, this is not used unless you have a special dial out mechanism from your PBX (refer to your modem manual). You can update this field.

Hangup PrefixDisplays the prefix to use when terminating a modem session (generally ‘+++’). You can update this field.

Hangup SuffixDisplays the prefix to use when terminating a modem session (generally ‘ath’). You can update this field.

EtherMeter Download Control View

You can access the EtherMeter Download Control view by clicking on the Download Control button in the NAT EtherMeter Device Configuration view. This view controls the downloading of firmware from a server to the EtherMeter. This view provides the following information:

NOTE

Non-printable characters can be used in the initialization string by entering a back slash (\) followed by the character value or ASCII code; for example, \0703. The ASCII code should be represented by two hexadecimal digits. To enter a back slash as part of the string, use two back slashes, \\.




Download Server AddressDisplays the IP address of the TFTP server from which the FLASH code will be downloaded. You can update this field.

File NameDisplays the name of the file to be downloaded from the TFTP server. You can update this field.

StatusDisplays the current download operation status. You can initiate a download using the Start Downloading button. This field then shows the progress and success (or failure) of the operation. You cannot initiate a download when either the EtherMeter is waiting for downloading parameters (a Status of DownloadFileName or DownloadServerIP), or the downloading operation is in progress (a Status of ARP-Server-Sent, Rrq-Sent, or Downloading). If the Download Server Address and/or the File Name are not available within 60 seconds of your clicking on the Start Downloading button, the Status is set to Time-Out. You must reinitialize the downloading. Table 3-1 lists the valid status entries.

Table 3-1. Valid Status Entries

NAT EtherMeter Device Configuration ViewNAT EtherMeter Accessing Hosts Configuration View


NAT EtherMeter Accessing Hosts Configuration View

You can access the NAT EtherMeter Accessing Hosts Configuration view by clicking on the Accessing Hosts Tables button in the NAT EtherMeter Device Configuration view. This view allows you to define the access with which other devices can communicate with the EtherMeter. This is useful when a large network is managed remotely by a Network Administrator and monitored locally by a secondary station. Each accessing host can have a different access level; for example, if you grant Read Trap access to a local monitoring station, that station can set its own alarms. The local station can monitor the network, but since it does not have Read Write access, corrective action cannot be undertaken – it remains the responsibility of the Network Administrator. This view provides two inter-related tables, the Accessing Hosts Table and the Telephone Number and Traps Table. The maximum number of entries is 16.

Accessing Hosts Table

This table provides the access information for the hosts. This table consists of the following entries:

IP AddressDisplays the IP address of a host with access rights to the EtherMeter.

Time-Out-Download The downloading process has timed out: file transfer has not completed. Whenever the EtherMeter fails to receive the proper TFTP data packet, it retransmits the last ACK packet every 5 seconds. After 5 retries, the TFTP process is aborted.

Not-defined An unanticipated error occurred.

File-Not-Found The download file was not found.

Access-Violation A security access violation occurred.

Disk-Full The allocation of space has been exceeded.

Illegal-Operation An illegal TFTP operation was encountered.

Unknown-Transfer-ID

An unknown transfer ID was encountered.

File-Exists Download file has been found to exist.

No-Such-User An invalid user has been entered.

Table 5-2. Available Top Ten Selection Criterion

Peaks Sampling IntervalDisplays the period, in seconds, over which samples are taken to establish peak values. For example, if you set this field to 10 seconds, after every 10 second period counters would be read and the time and actual counts of the period(s) with the highest counts are recorded. You can update this field.

Top10 Sampling IntervalDisplays the sampling interval for the collection of top ten statistics, in seconds. The default value is 3 seconds, and values between 1 and 6500 seconds are valid entries. You can modify this value.

Threshold Trap ValueDisplays and allows you to modify the threshold for generating top ten traps, if the EtherMeter is configured to generate traps. When the frame count of a top ten station exceeds this threshold value, a top ten trap is generated. For example, if the selection criterion is Ethernet Broadcaster and the threshold trap value is 100, then a trap will be sent each time more than 100 frames per second, originating from a Ethernet Broadcast station, are seen by the EtherMeter. Any non-zero value enables the sending of traps. A value of zero indicates top ten information is not displayed.

RMON Filter and Channel Configuration View

CommunityDisplays the SNMP community name associated with any trap generated for this event. You can update this field in the Configuration Detail view.

Last SentDisplays the System UpTime value at the time the entry last generated an event. If the entry has not generated any event, this field has a zero value.

DescriptionDisplays a textual description of the entry. You can update this field in the Configuration Detail view.

This button opens the RMON Event Log Table. This shows the Event Index, its number in the Log Table, time of logging, and a description of every event generated by the EtherMeter.

This button allows you to add or modify an event. Type in the event index to add or modify, then save and commit the index by clicking save. Click on the Config Detail button to access the Event Capture view.


You can access the RMON Filter and Channel Configuration view by clicking on the RMON Filters/Channels button in the EtherMeter Extended RMON Configuration view. This view contains the Filter Table and the Channel Table. The Filter Table defines a filtering pattern against which packets are matched. The matching packets form a data stream (or channel), as defined in the Channel Table. The data stream can be captured (see the Packet Capture Buffer Control view) or can generate an event. The EtherMeter can support up to ten filters (Filter Table entries) and up to ten channels.

Filter Table

Each entry in this table defines one filtering condition to be applied to every packet received on the ethernet interface of the EtherMeter. You can create up to five filters. This table provides the following information:

FilterDisplays the index for entries in this table.

ChannelDisplays the name of the channel associated with this filter. The same name is used in the Channel Table.

ChannDisplays the channel for this table entry. This is the index for this table and corresponds to a value in the Channel field in the Filter Table.

AcceptTypeDisplays and allows you to modify the action of filters associated with this channel. Table 5-15 displays the valid entries for this field.

StatusDisplays the status of this channel entry.

Add Filter

Table 5-15. Valid AcceptType Entries

Entry Definition

AcceptMatched Packets will be accepted to this channel if they passed both the data and the status matches in the associated filter.

AcceptFailed Packets will be accepted to this channel only if they failed one of the matches in the associated filter(s).




DataCtrlDisplays and allows you to modify the flow of data through this channel. If it is set to On, data, status, and events flow through this channel; that is, matched packets may generate events or be captured by the Packet Capture function. The default setting is Off.

ONevntDisplays and allows you to modify the event that is configured to turn the channel Data Control from Off to On. This event is defined in the Event Table. If there is no entry with this event index, then no association exists and this field should be set to zero.

OFFevntDisplays and allows you to modify the event that is configured to turn the channel Data Control from On to Off. This event is defined in the Event Table. If there is no entry with this event index, then no association exists and this field should be set to zero.

EvtIndxDisplays and allows you to modify the event that is configured to be generated when the channel Data Control is On and a packet is matched. This event is defined in the Event Table. If there is no entry with this event index, then no association exists and this field should be set to zero.

EvntStatusDisplays and allows you to modify the event status of the channel. You can use this to control the flow of events, if this channel is configured to generate events, when packets are matched. Table 5-16 lists the valid settings for this field.

MatchesDisplays the number of matches on this channel to the filtering conditions set up in the Filter Table.This field is updated even if the DataCtrl field is set to Off.

Table 5-16. Valid Event Status Entries

Entry Definition

EventReady A single event may be generated after which the EvntStatus will be set to EventFired by the EtherMeter. This is the default setting.

EventFired No events will be generated until this field is updated to EventReady or EventAlwaysReady.

EventAlwaysReady Disables the flow control and allows events to be generated at will. This setting is not recommended because it may result in high network traffic or other performance problems.

Extended RMON ApplicationRMON Packet Capture Buffer Control View


OwnerDisplays the owner of the table resources you are using. The owner name is usually assigned by the network administrator.

This button allows you to add or modify a channel. Type in the channel index to add or modify, then save and commit the index by selecting Save. Click on the Config Detail button to access the Channel Capture view.

RMON Packet Capture Buffer Control View

You can access the RMON Packet Capture Buffer Control view by clicking on the RMON Packet Capture button in the EtherMeter Extended RMON Configuration view. This view controls the capture of packets from associated channels and places them in a buffer specified by the Capture Buffer Table. Each entry controls one set of packets that is captured and controlled by one or more filters. Up to ten entries are allowed. This view provides the following information:

IndexDisplays the index for the entry in this table is displayed.

ChannelDisplays and allows you to modify the channel that is the source of packets being captured. This corresponds to a channel in the Channel Table from the RMON Filter and Channel Configuration View.

StatusDisplays and allows you to modify the status of this entry.

FullStatusDisplays the status of the memory allocated to this channel in the EtherMeter’s buffer. Possible values are: Full (memory is full), or Available (free memory remains).

FullActionDisplays the action to take when the buffer is full. Possible values are: Lock (stop capturing data when the buffer is full), or Wrap (keep capturing data, turning out the oldest data in the allocated memory as necessary to make room for it).

CaptureSizeDisplays the maximum amount of data (octets) in a frame that will be saved in this capture buffer (even if the packet size is larger). If this field is set to zero, the capture buffer will save as many octets as is possible.

BufferSizeDisplays the number of bytes of the EtherMeter’s buffer that have been allocated to this channel.

EtherMeter IP Mapping Tables Control View

You can access the EtherMeter IP Mapping Tables Control view by highlighting the NATRmonXApp icon and then selecting IP Mapping from the Icon Subviews menu, or by clicking on the EtherMeter IP Mapping button in the EtherMeter Extended RMON Configuration view. This view displays a table of MAC address to IP address mappings. Any duplicate MAC entries (such as would be produced by a router) can be entered into a separate table of router MAC addresses. This will prevent unecessary trap messages being generated for duplicate addresses or address changes.

The EtherMeter IP Mapping Tables Control view provides the following information:

IndexDisplays an index uniquely identifying the entry.

HostIndexDisplays the Host Table on which the MAC to/from IP mapping table will be based. You can update this field if the status is not set to Valid. Values for this field can range between 1 and 65535.

EntriesDisplays the total number of entries in the mapping tables.

UpTimeDisplays the time since the control entry was validated.

TrapsDisplays and allows you to configure whether traps will be generated if Duplicate IP Address or IP Address Change is detected.

NOTE

Double-clicking on the Status field displays the Configuration Detail View.

Extended RMON ApplicationEtherMeter New Node Discovery Control View


StatusDisplays and allows you to modify the mapping status. When the status is Valid, the physical address to/from IP address mapping function is enabled (if the associated Host Table exists; if not, a ‘BadValue’ error message will be returned). When the setting is not Valid, the mapping function is disabled and the entries in the two mapping tables, if any, are cleared. Table 5-17 lists the valid settings for this field.

ChangesDisplays the number of times the IP Address of any mapping has changed.

DuplicatesDisplays the number of times the IP address of any mapping was found to be a duplicate.


EtherMeter New Node Discovery Control View

You can access the EtherMeter New Node Discovery Control view by highlighting the NATRmonXApp icon and then selecting New Node Discovery from the Icon Subviews menu, or by clicking on the EtherMeter NND button in the EtherMeter Extended RMON Configuration view. Each entry in the table contains a list of parameters that set up the new node detection function on a Host Table. When you enable new node detection, the Host Table on which you are detecting new nodes is ‘frozen’. Any addresses detected, which were not in the host Table at the point it was frozen, are considered to be new nodes. New nodes are logged in a New Node Table. This view provides the following information:

Table 5-19. Valid Control Mode Entries

Entry Definition

Freeze The associated Freeze Size is loaded with the table size of the associated RMON Host Table. The associated Up Time is reset to zero. Traps are generated if new addresses are found and the Traps field is set to Enable. The new addresses are still learned by the RMON Host Tables and also learned by the associated New Node Detection Host Table and New Node Detection Host Time Table. This is the default state.

Edit The associated RMON Host Table stops learning new nodes but still updates the statistics for the existing host entries. All the entries in the New Node Detection Host Table and New Node Detection Host Time Table are deleted and the Up Time stops increasing.

Clear All the entries in the associated RMON Host Table are deleted. The entries in the New Node Detection Host Table and New Node Detection Host Time Table, if any, are also deleted and the Up Time is set to zero.

NOTE

The Clear operation only occurs if the Control Status is Valid.
