Catalyst 2000 MIB Extensions

The Catalyst 2000 MIB extensions are grouped into the following categories:

These groups and their associated MIB objects are detailed in the following sections.

System Information

All objects in this group are read-only and return system-wide information. This group is one set of extensions to the MIB II System Group, with some objects serving as mirror images of objects in the System Configuration (sysConfig) Group.

This read-only MIB object returns the revision number of the forwarding engine ASIC.

sysInfoBoardRevision (integer)

This read-only MIB object returns the revision number of the main Catalyst 2000 board on which the Catalyst 2000 firmware resides.

sysInfoTotalNumberOfPorts (integer)

This read-only MIB object displays the total number of physical ports. This MIB object does not represent the upper bound of indices into port tables. See sysInfoNumberOfSwitchPorts and sysInfoNumberOfSharedPorts for that purpose.

Valid Values:

25 to 41

sysInfoNumberOfSwitchPorts (integer)

This read-only MIB object displays the number of ports that are individually switched. This number includes the high-speed expansion slots.

Within each octet, the most significant bit represents the lowest numbered LED.

System Configuration

This group consists of another set of extensions to the MIB II System Group. All objects in this group are read-write; some objects serve as a definable mirror image of objects in the System Information (sysInfo) Group.

sysConfigReset (integer)

Setting this read-write MIB object to reset causes a complete reset of both hardware and software but does not run the POST (Power-On Self-Test). All parameters, including all static addresses, are retained.

Setting this object to noReset has no effect. The Catalyst 2000 always returns the value noReset when this object is read.

Valid Values:

noReset

(1)

reset

(2)

Default Value:

noReset

(1)

sysConfigDefaultReset (integer)

Setting this read-write MIB object to reset causes a complete reset of both hardware and software but does not run the POST (Power-On Self-Test). All configuration parameters will revert to their factory default settings, and all addresses assigned will be removed. The content of FLASH memory remains unchanged. The Catalyst 2000 will execute the firmware from the same source (EPROM or FLASH) after coming out of reset.

Setting this object to noReset has no effect. The Catalyst 2000 always returns the value noReset when this object is read.

Valid Values:

noReset

(1)

reset

(2)

Default Value:

noReset

(1)

sysConfigClearPortStats (integer)

Setting this read-write MIB object to noClear results in no action. When set to clear, the Catalyst 2000 will reset all port statistics to zero. Port statistics are kept in the switchPortTable, the switchPortTxStatTable, the switchPortRxStatTable, and the switchPortTxCollTable.

This object always returns noClear when read.

Valid Values:

noClear

(1)

clear

(2)

Default Value:

noClear

(1)

sysConfigAddressViolationAction (integer)

This read-write MIB object indicates what action to take when an address violation (an address mismatch or duplication) occurs on a secure port.

Available actions are:

sysConfigAddressViolationAlert (integer)

When this read-write MIB object is set to enabled, the Catalyst 2000 will generate an addressViolation trap upon detecting an address violation on a secure port. When set to disabled, no such trap will be issued for address violation on secure ports.

Valid Values:

enabled

(1)

disabled

(2)

Default Value:

enabled

(1)

sysConfigSwitchingMode (integer)

The Catalyst 2000 can operate as a high speed cut-through switch, or as a traditional store-and-forward switch. Cut-through switching of frames is enabled when this read-write MIB object is set to Fast-Forward or FragmentFree. This works to reduce buffering latency by attempting to forward a frame before reception is completed. Cut-through switching does not take effect for frames that are addressed to a broadcast address. These frames are switched using the store-and-forward method. Multicast frames can be switched as set by this MIB object or can be forced to the store-and-forward mode using the object sysConfigMulticastStoreAndForward.

The three possible switching modes are defined as follows:

sysConfigMulticastStoreAndForward (integer)

When this read-write MIB object is set to enabled, the switching of multicast frames will use the store-and-forward method, regardless of the setting of sysConfigSwitchingMode. When set to disabled, multicast frames will be switched according to the current setting of sysConfigSwitchingMode.

Valid Values:

enabled

(1)

disabled

(2)

Default Value:

disabled

(2)

sysConfigMonitor (integer)

This read-write MIB object selects whether frames to or from certain ports are sent to sysConfigMonitorPort. A port is selected for monitoring purposes when its swPortMonitoring object is set to enabled.

Valid Values:

enabled

(1)

disabled

(2)

Default Value:

disabled

(2)

sysConfigMonitorPort (integer)

This read-write MIB object displays the port number to which all frames to or from monitored ports are sent. Frames are only monitored if the sysConfigMonitor object is set to enabled.

Port 0 specifies that frames are to be monitored internally by the Catalyst 2000 switch. A number from 1 to 27 selects a Catalyst 2000 switch port. The number 26 selects port F1 (called port A on the Catalyst 2800), 27 selects port F2 (port B on the Catalyst 2800). The number 31 selects no monitor port.

Valid Values:

0 to sysInfoTotalNumberOfPorts, 31

Default Value:

31

sysConfigHigherProtocolMonitor (integer)

This read-write MIB object selects whether frames addressed to and from the higher-layer protocol processor of the Catalyst 2000 switch are to be monitored. The higher-layer protocol processor is the entity that responds to all SNMP/TFTP/XNSEcho management requests.

Valid Values:

enabled

(1)

disabled

(2)

Default Value:

disabled

(2)

sysConfigPort25Connector (integer)

This read-write MIB object is used to specify which of the two connector types is providing active connection on port 25. Setting the connector to self-sensing allows the Catalyst 2000 switch to learn the active connector for port 25 on its own. The other two possible values which force the Catalyst 2000 switch to use the chosen type are:

sysConfigHeuristics (integer)

This read-write MIB object displays a value which enables special heuristic functions to be used by Cisco customer support.

sysConfigEnableSTP (integer)

The Catalyst 2000 switch implements the 802.1d Spanning-Tree Protocol on all its ports to detect loops in the bridge topology. The user may, for any reason, elect to disable the execution of Spanning-Tree Protocol by setting this read-write MIB object to disabled.

When Spanning-Tree Protocol is disabled, all ports currently in suspended-stp status will immediately transition to enabled status and frame forwarding will resume. When Spanning-Tree Protocol is enabled, after having been previously disabled, all ports will transition to suspended-stp status. Suspended-stp ports will transition to enabled according to the Spanning-Tree Protocol.

Valid Values:

enabled

(1)

disabled

(2)

Default Value:

enabled

(1)

sysConfigStrictSTPTransition (integer)

The 802.1d Spanning-Tree Protocol dictates that a port must start out in the blocking state and transition through two other intermediate states, listening and learning, before it can begin forwarding frames. These state transitions help prevent temporary loops in the bridge topology.

The Catalyst 2000 switch implements a special algorithm where a single address port may move to the forwarding state as soon as it is enabled after having been suspended for address violation or jabber. In the strictest sense, this does not comply with the 802.1d Spanning-Tree Protocol. To force compliance, set this read-write MIB object to enabled.

Valid Values:

enabled

(1)

disabled

(2)

Default Value:

disabled

(2)

netMgmtModemInitString (display string)

This read-write MIB object is the initialization string used to configure an attached modem. Specify this string with up to 48 characters if the modem is not Hayes compatible. Only the initialization commands need to be specified. Do not specify any modem prefix string such as the AT attention sequence, or any suffix such as the CR character.

This string takes effect after every line hang-up.

Default Value:

E0V1M1

netMgmtModemDialString (display string)

This read-write MIB object string of up to 48 characters contains a phone number which is used to establish a modem connection with a remote site. Only the phone number needs to be specified (that is, do not specify any dial prefix string such as ATDT).

Leave this string empty if this dial-out capability is not desired. This string takes effect after every line hang-up.

netMgmtModemDialDelay (integer)

This read-write MIB object specifies a delay in seconds between every dial-out failure. The value zero indicates an infinite delay. Normally, the Catalyst 2000 switch will attempt a dial-out if the netMgmtModemDialString object is non-empty. If the remote site then fails to answer, and auto-answer has been disabled on this system, the system will retry the dial-out attempt after this delay has passed.

This read-only MIB object returns the revision number of the Catalyst 2000 switch firmware residing in EPROM. The string has the format V2.01.

upgradeFlashSize (integer)

This read-only MIB object displays the size of available FLASH memory in the system, in kilobytes. For example: 128 equals 131072 bytes (128 bytes times 1024).

upgradeFlashBankStatus (display string)

This read-only MIB object displays a text string indicating status and version of last upgrade version, including the source of the upgrade version, and the date and time of upgrade. The string is in net ASCII and conforms exactly to one of the following formats, depending upon the source of the upgrade:

upgradeTFTPServerAddress (IpAddress)

This read-write MIB object contains the IP address of a TFTP server from which a firmware image can be downloaded. The download may be initiated by setting the upgradeTFTPInitiate to upgrade, or via an out-of-band management action.

Default Value:

0.0.0.0, or no address

upgradeTFTPLoadFilename (display string)

This read-write MIB object contains the name of the file of up to 80 characters containing a firmware upgrade image on the host whose address is given by upgradeTFTPServerAddress.

Default Value:

empty string, or no filename

upgradeTFTPInitiate (integer)

Setting this read-write MIB object to noUpgrade results in no action. When set to upgrade, the Catalyst 2000 switch will attempt to download a firmware upgrade image from the server whose address is given by upgradeTFTPServerAddress. The image is found in the file whose name is given by upgradeTFTPLoadFilename. Both upgradeTFTPServerAddress and upgradeTFTPLoadFilename must be non-empty for the upgrade to proceed.

This object always returns noUpgrade when read.

Valid Values:

upgrade

(1)

noUpgrade

(2)

Default Value:

noUpgrade

(2)

upgradeAutoExecute (integer)

This read-write MIB object indicates whether a newly upgraded firmware version should immediately be selected for execution. When this object is disabled, the user must explicitly set the upgradeFirmwareSource object to select and run a particular firmware version after an upgrade.

When this object is enabled after a successful firmware upgrade, the Catalyst 2000 switch will automatically switch to run the new firmware.

Valid Values:

enabled

(1)

disabled

(2)

Default Value:

enabled

(1)

upgradeTFTPAccept (integer)

This read-write MIB object controls the second method of firmware upgrade using TFTP. The Catalyst 2000 switch has a UDP Listener on the TFTP server port, and can accept upgrade requests from any workstation with Internet Protocol TFTP software.

This object enables or disables the TFTP Upgrade Listener. When disabled, no TFTP workstations can download a firmware upgrade image to the Catalyst 2000 switch.

Valid Values:

enabled

(1)

disabled

(2)

Default Value:

enabled

(1)

The VLAN Group

vlanMaxSupported (integer)

This read-only MIB object displays the maximum number of virtual LANs supported. This object represents the upper bound of the index into the vlanTable.

Valid Values:

4

vlanAllowMembershipOverlap (integer)

Caution verlapped VLANs may lead to loops or loss of connectivity in the spanning-tree topology and should only be used with caution.

When set to disabled, the Catalyst 2000 switch will ensure that no port can simultaneously be a member of more than one VLAN.

Valid Values:

enabled

(1)

disabled

(2)

Default Value:

disabled

(2)

vlanTable

This read-only MIB object displays a list of configuration entries for a VLAN.

vlanIndex (integer)

This read-only MIB object displays the number from 1 to vlanMaxSupported identifying a configured VLAN.

vlanName (display string)

This read-write MIB object contains a descriptive string of up to 60 characters used by the network administrator to name a VLAN.

vlanMemberPorts (octet string)

This read-only MIB object displays the set of Catalyst 2000 switch member ports for the VLAN. A port may reside within multiple VLANs only if the object vlanAllowMembershipOverlap has been set to enabled.

This object cannot be used to configure VLAN membership. The table vlanMemberTable is used for that purpose.

Each octet within the value of this object specifies a set of eight ports, with the first octet specifying ports 1 through 8, the second octet specifying ports 9 through 16, and so on. Within each octet, the most significant bit represents the lowest numbered port, and the least significant bit represents the highest numbered port. Thus, each port of the VLAN is represented by a single bit within the value of this object. If that bit has a value of 1 then that port is included in the set of ports; the port is not included if its bit has a value of 0.

Initially, a single VLAN includes all ports.

Default Value:

All ports

vlanIpAddress (IpAddress)

This read-write MIB object sets the administrative IP address for this VLAN. Note that once a value has been set for this object, the next write will only take effect after a system reset.

Default Value:

same as the address contained in netMgmtIpAddress

vlanIpSubnetMask (IpAddress)

This read-write MIB object contains the administrative IP subnet mask for this VLAN. A change in the subnet mask at any time will immediately take effect.

Default Value:

same as the mask contained in netMgmtIpSubnetMask

vlanMemberTable

This read-only MIB object displays a list of port membership configuration entries for a VLAN.

vlanMemberIndex (integer)

This read-only MIB object displays the number from 1 to vlanMaxSupported identifying a configured VLAN. The same value of a VLAN index variable for any of the VLAN tables in this MIB group selects the same VLAN.

vlanMemberPortIndex (integer)

This read-only MIB object displays the number from 1 to sysInfoNumberOfSwitchPorts identifying an individually switched port. The same value of a port index variable for any of the port tables selects the same port.

vlanMemberPortOfVlan (integer)

This read-write MIB object contains the port identified by vlanMemberPortIndex and becomes a member of the VLAN identified by vlanMemberIndex when this object is set to true. The same port ceases to be member of that VLAN when the object is set to false.

All ports in the Catalyst 2000 switch must belong to some VLAN. Consequently, the Catalyst 2000 switch will return badValue if this object is used to remove the port from all membership lists.

Note that when vlanAllowMembershipOverlap is disabled, a port can only be member of exactly one VLAN. In this case, setting vlanMemberPortOfVlan to true for a port adds the port to the membership list of the current VLAN and removes the same port from all other VLAN membership lists.

When vlanAllowMembershipOverlap is enabled, a port may reside in multiple VLANs. Setting vlanMemberPortOfVlan to true in this case adds the port to the membership list of the current VLAN and does not change other VLAN membership lists.

Valid Values:

true

(1)

false

(2)

Bandwidth Usage Information

bandwidthUsageCurrent (counter)

This read-only MIB object displays the bandwidth currently consumed. The measurement unit is in megabits per second (1,000,000 bits/second).

bandwidthUsagePeakInterval (integer)

This read-write MIB object specifies the length of time which forms a peak bandwidth capture interval. A write to this object with any new value restarts the peak bandwidth capture at the first interval. In other words, the bandwidthUsagePeakTable will be cleared and entry number 1 will record the peak for a new first interval.

Valid Values:

one hour

(1)

three hours

(3)

six hours

(6)

twelve hours

(12)

one day

(24)

one week

(168)

Default Value:

one day

(24)

bandwidthUsagePeakRestart (integer)

This read-write MIB object is set to restart to clear the bandwidthUsagePeakTable and restart the peak bandwidth capturing at the current interval. No action will be taken if this object is set to noRestart. This object always returned noRestart when read.

Valid Values:

noRestart

(1)

restart

(2)

Default Value:

noRestart

(1)
