mlpppLSapLcMagicNumber
Module: CXMLPPP-MIB
OID (symbolic): CXMLPPP-MIB::mlpppLSapLcMagicNumber
OID (numeric): 1.3.6.1.4.1.495.2.1.6.49.50.1.22
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Determines whether the Magic Number is enabled or disabled.
The Magic Number is a unique random system generated number, present in every Configure-Request packet. The Magic Number is used to ensure that the same packet is not sent back and forth between the local and the remote in an endless loop.
If the Magic Number is enabled, then the local end of the link will check the Magic Number in each Configure-Request packet it receives. If the number is the same as its own, it will change its number and send a NoAcknowledge packet back to the remote. If the local end of the link continues to receive Configure-Requests with its own number, it assumes a loopback. After the number of Configure-Requests specified in mlpppUSapLcMaxConfigure of this table has been exceeded, the link will go down.
Note: Magic Number must be disabled when Multilink is used.
Options: enabled (1)
disabled (2)
Default Value: disabled (2)
Configuration Changed: administrative
What is mlpppLSapLcMagicNumber?
This OID enables or disables Magic Number checking on this local PPP port, defaulting to disabled; the MIB notes this must be disabled when Multilink is in use, since it's used to detect loopback conditions on individual (non-bundled) links. An engineer leaves this disabled on any link that is part of an MLPPP bundle, per the vendor's own requirement.
