Searching the Help
To search for information in the Help, type a word or phrase in the Search box. When you enter a group of words, OR is inferred. You can use Boolean operators to refine your search.
Results returned are case insensitive. However, results ranking takes case into account and assigns higher scores to case matches. Therefore, a search for "cats" followed by a search for "Cats" would return the same number of Help topics, but the order in which the topics are listed would be different.
Search for | Example | Results |
---|---|---|
A single word | cat
|
Topics that contain the word "cat". You will also find its grammatical variations, such as "cats". |
A phrase. You can specify that the search results contain a specific phrase. |
"cat food" (quotation marks) |
Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase. |
Search for | Operator | Example |
---|---|---|
Two or more words in the same topic |
|
|
Either word in a topic |
|
|
Topics that do not contain a specific word or phrase |
|
|
Topics that contain one string and do not contain another | ^ (caret) |
cat ^ mouse
|
A combination of search types | ( ) parentheses |

How to Discover Layer2 Connections Using Saved Files
This task includes the following steps:
-
Prerequisite - Set up protocol credentials
The SNMP protocol is required to discover Layer2 objects. When defining the SNMP protocol credentials, have available the Port and Community authentication parameters.
For credential information, see Supported Protocols.
-
Run the discovery
For details on running jobs, refer to "Module/Job-Based Discovery" in the HPE Universal CMDB Data Flow Management Guide.
Run the jobs in the following order:
-
Run the Range IPs by ICMP job to discover the target IPs.
-
Run the Host Connection by SNMP job to discover the target host and connectivity to it.
-
Run either or both of the Layer2 Topology Bridge-based by SNMP and Layer2 Topology VLAN-based by SNMP jobs, according to your environment.
-
After all the preceding jobs have completed, run the Process Layer2 Saved Files job.
