CISCO-SYSTEM-MIB file content
The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.
Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

This MIB module contains Cisco-defined extensions to the systemGroup." REVISION "200106220000Z" DESCRIPTION "Added SNMP authentication failure objects and clock changed notification."

Setting this object is equivalent to setting an automated clock and calendar. The value of the object will track the date and time from the value set. Note that due to hardware limitations some systems may not be able to preserve such meaning across reboots of the system, as indicated by csyClockLostOnReboot. A constant value of all zeros and length 8 indicates the system is not aware of the present date and time. This object may be read-only on some systems." ::= { csyClock 1 } csyClockLostOnReboot OBJECT-TYPE SYNTAX TruthValue MAX-ACCESS read-only STATUS current DESCRIPTION "Indication of whether the system can preserve knowledge of current date and time across a system reboot. A value of 'true' indicates the clock must be reset from some external source each time the system reboots. A value of 'false' indicates the system has the ability to keep time across reboots." ::= { csyClock 2 } -- Location Section csyLocationCountry OBJECT-TYPE SYNTAX CountryCode MAX-ACCESS read-write STATUS current DESCRIPTION "The country where the system is physically located. On some systems and for some technologies this value affects behavior, such as standards for communication. All such technologies should default to using the setting of this value, but may provide an override if necessary. The default value of this object is 'US'. Systems destined for other countries may use a different default. Systems in which the value does not affect operation should default to a zero-length value." ::= { csyLocation 1 } -- Generic Summertime Section csySummerTimeStatus OBJECT-TYPE SYNTAX TruthValue MAX-ACCESS read-write STATUS current DESCRIPTION "An indication of whether the summertime feature is enabled on this device. When this object is set to true, then csySummerTimeOffset, csySummerTimeRecurringStart and csySummerTimeRecurringEnd objects are set to default values.

DEFVAL { 'ff00010a0200'H } ::= { csySummerTime 4 } -- Scheduled Reset Section csyScheduledResetTime OBJECT-TYPE SYNTAX DateAndTime MAX-ACCESS read-write STATUS current DESCRIPTION "The scheduled date and time the switch will be reset at. The system will only take octet strings with length 8 for this object which indicates the local time of the switch. The maximum scheduled time is 24 days from the current system clock time. Setting this object value to be before the current system clock time or beyond the maximum scheduled time limit will be rejected by the system. Setting the object to all-zero octet strings will cancel the previously scheduled reset time and then the system will have no pending scheduled reset time. Setting this object value to be any valid octet strings other than the above cases will override the previously scheduled reset time and cause the system to be reset at the newly specified time. After the system has accepted the scheduled reset time, if the system clock is advanced ahead of the scheduled reset time, then reset will happen approximately 5 minutes after the current clock." ::= { csyScheduledReset 1 } csyScheduledResetAction OBJECT-TYPE SYNTAX INTEGER { reset(1), -- reset the system, resetMinDown(2) -- reset in minimal down time } MAX-ACCESS read-write STATUS current DESCRIPTION "Writing reset(1) to this object perform the normal reset operation on the active supervisor module.
