juniIpIfAssocIpIfIndex
Module: Juniper-IP-MIB
OID (symbolic): Juniper-IP-MIB::juniIpIfAssocIpIfIndex
OID (numeric): 1.3.6.1.4.1.4874.2.2.12.1.1.4.1.2
Node type: OBJECT-TYPE
Type: InterfaceIndexOrZero
Access: read-only
Description: The ifIndex of the IP interface associated with the lower layer juniIpIfAssocLowerIfIndex. In cases where there is not a 1 to 1 relationship between lower layer and higher layer IP interface, a zero value juniIpIfAssocIpIfIndex is returned; this includes the case where an IP interface has not yet been configued at the top of the interface column.
An example usage of this table:
Assume a user needs to know the ifIndex relationship for all interfaces with the L3 IP interface.
Then starting at the bottom of the stack below, the ATM and AAL5's ifIndex would be used to access the table. The agent will return 0 for each of these cases because multiple customer's traffic is demultiplexed at these levels.
IP_1 PPP IP_2 ATM1483_1 ATM1483_2 \ / AAL5 ATM
If the ATM1483_1 ifIndex is used to access this table, then the value of juniIpIfAssocLowerIfIndex will be set to the ifIndex of IP_1. Similarily, if the ATM1483_2 ifIndex is used to access this table, the juniIpifAssocLowerIfIndex will set to the ifIndex of IP_2.
What is juniIpIfAssocIpIfIndex?
The ifIndex of the IP (Layer 3) interface associated with a given lower-layer ifIndex, used to translate between L2 sublayer interfaces (e.g. ATM/AAL5) and their L3 IP interface for applications like billing; a value of zero means there isn't a clean 1-to-1 mapping (e.g. multiple customers demultiplexed at that layer).
