tmnxPortEtherDownWhenLoopedEnabled
Module: ALCATEL-IND1-TIMETRA-PORT-MIB
OID (symbolic): ALCATEL-IND1-TIMETRA-PORT-MIB::tmnxPortEtherDownWhenLoopedEnabled
OID (numeric): 1.3.6.1.4.1.6527.3.1.2.2.4.4.1.21
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description:
The value of tmnxPortEtherDownWhenLoopedEnabled specifies whether physical loop detection for the Ethernet port is enabled or disabled. When enabled, the port will periodically send out keep-alive PDUs with an EtherType of 0x9000. If the port receives a keep-alive that it transmitted, tmnxPortState will be set to 'linkUp' if it was previously 'up'. The port will not move back to tmnxPortState 'up' for a period of time defined by tmnxPortEtherDownWhenLoopedRetry, but will continue to periodically send out keep-alive PDUs. Every time the port receives a keep alive it sent while a loop has been detected, it will reset the time period that it will remain down as defined by tmnxPortEtherDownWhenLoopedRetry.
What is tmnxPortEtherDownWhenLoopedEnabled?
Enables or disables physical loop detection on an Ethernet port using periodic keepalive PDUs with Ethertype 0x9000. When the port receives its own keepalive back, it detects a loop and brings the port down.
