ipxCircLowerIfAlias
Module: CROUTE-MIB
OID (symbolic): CROUTE-MIB::ipxCircLowerIfAlias
OID (numeric): 1.3.6.1.4.1.81.31.2.1.1.3
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-write
Description: This object is an 'alias' name for the lower-layer interface on top of which this IP interface is defined. The alias is specified by the network manager, and provides a non-volatile 'handle' for the lower-layer interface. The semantics of the object are similar to the semantics of the ifAlias object, defined by the Interfaces MIB. At the time when this Madge MIB object was defined, the latest release of the Interfaces MIB was draft-ietf-ifmib-mib-05.txt. The purpose is to support all methods (static or dynamic) for creation of interfaces and to allow creation of IPX table entries without the need of the layer 2 interface to be present on the device at the time of the creation. It is assumed that some implementation dependent mechanisms allow the IPX application to be informed about the creation of new lower layer interfaces.
What is ipxCircLowerIfAlias?
This read-write DisplayString, up to 16 characters, lets an admin assign a persistent alias to the lower-layer interface underlying an IPX circuit, mirroring ipInterfaceLowerIfAlias but for the IPX side of the device's configuration. An admin sets this so IPX circuit references remain stable even if the underlying interface's numeric index changes after a reboot. For example, aliasing the lower-layer interface as IPX-Seg1 gives scripts a stable name to reference regardless of later renumbering.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.81.31.2.1.1.3 snmpwalk -v2c -c public <target> CROUTE-MIB::ipxCircLowerIfAlias
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.81.31.2.1.1.3.1 snmpget -v2c -c public <target> CROUTE-MIB::ipxCircLowerIfAlias.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.81.31.2.1.1.3.1 s <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ipxCircLowerIfAlias.1
