LLDP neighbor change event subscription
Subscription phase
result1_value, result2_description = ops.lldp.subscribe(tag, event, interfaceName, neighborType)
Parameter |
Description |
Value |
|---|---|---|
tag |
Indicates conditions. |
The value is a string of 1 to 12 case-insensitive characters, consists of letters, digits, and underscores (_), and starts with a letter. The value cannot be one of the following: "", None, and, or, andnot. The value cannot contain \0. |
event |
Indicates an LLDP neighbor change event. |
The value is of the enumerated type:
|
interfaceName |
Indicates the interface name consisting of the interface type and number. |
The value is a string of characters.
|
neighborType |
Indicates the LLDP neighbor device type. |
The value is of the enumerated type:
|
The result1_value and result2_description in the API prototype indicate return values.
The result1_value is the first return value, 0 indicates success, and 1 indicates failure.
The result2_description is the second return value, indicating the failure cause. It is returned only when the first return value is 1.
If multiple simple events are defined using the ops.lldp.subscribe API in the subscription phase, but the simple events are not combined through the Multi-Condition Combination API, the Python script assistant cannot be configured.
Using the LLDP neighbor change event subscription, you can subscribe to LLDP neighbor changes on an interface.
When a new LLDP neighbor on GE0/0/1 is a switch, the corresponding action is triggered.
