Hello guys,


Is there any solution to show ifAlias when a switch sends a snmptrap LinkUp or LinkDown?


Acording to this doc (https://support.huawei.com/enterprise/my/doc/EDOC1000027455?section=j00e), it only sends:


ifIndex

ifAdminStatus

ifOperStatus

ifDesc

Hello,

Description

This object is an "alias" name for the interface as specified by a network manager, and provides a non-volatile "handle" for the interface.

On the first instantiation of an interface, the value of ifAlias associated with that interface is the zero-length string.

As and when a value is written into an instance of ifAlias through a network management set operation, then the agent must retain the supplied value in the ifAlias instance associated with the same interface for as long as that interface remains instantiated, including across all re-initializations/reboots of the network management system, including those which result in a change of the ifIndex value of the interface.

An example of the value which a network manager might store in this object for a WAN interface is the (Telco's) circuit number/identifier of the interface.

Some agents may support write-access only for interfaces having particular values of ifType.

An agent which supports write access to this object is required to keep the value in non-volatile storage, but it may limit the length of new values depending on how much storage is already occupied by the current values for other interfaces.

Currently, the read length of alias is 1 to 242, and the written length of alias is 1 to 64. Do not support modifying this item on the Logic-Channel interface.

Max Access

Read-write

Cannot the NMS directly read the alias and associate it with the event?
