CISCO-FLEX-LINKS-MIB

AI MIB Summary

The CISCO-FLEX-LINKS-MIB manages Layer 2 interface redundancy pairs on Cisco devices by monitoring primary and backup link states, operational status, and failover counters to replace Spanning Tree Protocol (STP) in environments requiring deterministic link failover.

This MIB module is for configuration and status query of Flex Links feature on the Cisco 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.

cflIfConfigTableThis 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.
SEQUENCE OF CflIfConfigEntry
.1.3.6.1.4.1.9.9.471.1.1.1
cflIfConfigEntryAn 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.

cflIfConfigBackUpThe object indicates the back up interface in this Flex Links pair. 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.rw

cflIfConfigMmuPrimaryVlanThe object specifies the MAC address-table Move Update primary VLAN for the Flex Links interface pair. A value of zero indicates that no primary VLAN has been configured for MAC address-table Move Update.rw

.1.3.6.1.4.1.9.9.471.1.1.3.1.1
cflIfConfigPreemptionModeThe object specifies the preemption mechanism for a Flex Link interface pair. off - No preemption happens from active interface to backup interface. forced - The active interface always preempts the backup interface. The preemption occurs after the time specified in cflIfConfigPreemptionDelay. bandwidth - The interface with higher bandwidth always acts as the active interface.rw

cflIfStatusEntryAn 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 cflIfConfigTable, entries corresponding to cflIfConfigPrimary and cflIfConfigBackUp are created in this table. Entry is deleted when an interface is removed from a Flex Links. When an entry is removed from the cflIfConfigTable, entries corresponding to cflIfConfigPrimary and cflIfConfigBackUp are deleted from this table.

cflIfStatusThe status of an interface which is participating in Flex Links operation. 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 'waitingToSync' indicates that, the interface is participating in Flex Links operation and is waiting to sync with its peer interface. A value of 'waitingForPeerState' indicates that, the interface is participating in Flex Links operation and is waiting for its peer's state. A value of 'unknown' indicates that, the interface is participating Flex Links operation and has entered an unknown state. A value of 'vlbAll' indicates that, the interface is linkup and VLANs preferred on the peer interface are moved to this interface of the Flex Link pair. This means that this interface carries all preferred VLANs of the Flex Link pair. A value of 'vlbConfig' indicates that, the interface is linkup and VLANs preferred on this interface have moved to forwarding state on the interface. A value of 'vlbPreempt' indicates that, the interface is linkup and waiting for the timer to expire to move into 'vlbConfig' state.ro
