CONTACT-INFO "http://www.eltex.nsk.ru" DESCRIPTION "This MIB module is for configuration and status query of Flex Links feature on the Eltex device. Flex Links are a pair of Layer 2 interfaces, where one interface is configured to act as a backup to the other. The feature provides an alternative solution to the Spanning Tree Protocol (STP), allowing users to turn off STP and still provide basic link redundancy. Flex Links are typically configured in service provider or enterprise networks where users do not want to run STP on the device." ::= { eltexLtd 31 } eltexFlexLinksMIBNotifs OBJECT IDENTIFIER ::= { eltexFlexLinksMIB 0 } eltexFlexLinksMIBObjects OBJECT IDENTIFIER ::= { eltexFlexLinksMIB 1 } eltexFlexLinksMIBConformance OBJECT IDENTIFIER ::= { eltexFlexLinksMIB 2 } eltexFlConfig OBJECT IDENTIFIER ::= { eltexFlexLinksMIBObjects 1 } eltexFlStatus OBJECT IDENTIFIER ::= { eltexFlexLinksMIBObjects 2 } -- Flex Links configuration table eltexFlIfConfigTable OBJECT-TYPE SYNTAX SEQUENCE OF EltexFlIfConfigEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "This table allows user to configure Flex Links. The Flex Links feature requires interface pairs to be setup. This table allows user to specify such interface pairs. An interface can become part of only one such interface pair at any given time." ::= { eltexFlConfig 1 } eltexFlIfConfigEntry OBJECT-TYPE SYNTAX EltexFlIfConfigEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "An entry containing information about Flex Links configuration. Each entry configures a pair of interfaces for a Flex Links. Only those Layer 2 interfaces which are capable of performing Flex Links operation may be configured in this table. Once an interface is configured as part of a Flex Links pair, such an interface, can not be configured as a part of other Flex Links pairs."

The value of this object is changed to 0 (zero) if this interface is removed from the ifTable. The SNMP agent is responsible for updating this object's value once the interface is added to the ifTable. The value of 0 (zero) cannot be set." ::= { eltexFlIfConfigEntry 2 } eltexFlEnableStatusChangeNotif OBJECT-TYPE SYNTAX TruthValue MAX-ACCESS read-write STATUS current DESCRIPTION "This variable indicates whether the system produces the eltexFlIfStatusChangeNotif.

The preemption occurs after the time specified in eltexFlIfConfigPreemptionDelay. bandwidth - The interface with higher bandwidth always acts as the active interface." ::= { eltexFlIfConfigExtEntry 1 } eltexFlIfConfigPreemptionDelay OBJECT-TYPE SYNTAX Unsigned32 UNITS "seconds" MAX-ACCESS read-write STATUS current DESCRIPTION "The object specifies the delay time until an interface preempts another interface for a Flex Link interface pair." ::= { eltexFlIfConfigExtEntry 2 } -- Flex Links status table eltexFlIfStatusTable OBJECT-TYPE SYNTAX SEQUENCE OF EltexFlIfStatusEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "A list of interfaces which are members of Flex Links." ::= { eltexFlStatus 1 } eltexFlIfStatusEntry OBJECT-TYPE SYNTAX EltexFlIfStatusEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "An entry, containing status information about a Flex Links interface. Entry is created when an interface is configured as a member of a Flex Links. When an entry is created in the eltexFlIfConfigTable, entries corresponding to eltexFlIfConfigPrimary and eltexFlIfConfigBackUp are created in this table. Entry is deleted when an interface is removed from a Flex Links. When an entry is removed from the eltexFlIfConfigTable, entries corresponding to eltexFlIfConfigPrimary and eltexFlIfConfigBackUp are deleted from this table."

A value of 'forwarding' indicates that, the interface is participating in Flex Links operation and is actively forwarding traffic. A value of 'blocking' indicates that, interface is participating in Flex Links operation and is ready to forward traffic if the interface it backs up in Flex Links operation goes down. A value of 'down' indicates that, the interface participating in Flex Links operation has gone down. A value of 'unknown' indicates that, the interface is participating Flex Links operation and has entered an unknown state." ::= { eltexFlIfStatusEntry 2 } -- Notifications eltexFlIfStatusChangeNotif NOTIFICATION-TYPE OBJECTS { eltexFlIfIndex, eltexFlIfStatus } STATUS current DESCRIPTION "A eltexFlIfStatusChangeNotif is generated when the value of eltexFlIfStatus changes." ::= { eltexFlexLinksMIBNotifs 1 } -- Conformance eltexFlexLinksMIBCompliances OBJECT IDENTIFIER ::= { eltexFlexLinksMIBConformance 1 } eltexFlexLinksMIBGroups OBJECT IDENTIFIER ::= { eltexFlexLinksMIBConformance 2 } eltexFlexLinksMIBCompliance MODULE-COMPLIANCE STATUS current DESCRIPTION "The compliance statement for entities which implement the ELTEX-FLEX-LINKS-MIB."
