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.
Words and Phrases
| 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. |
Using Boolean Operators
| 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 |

Discovering Server-to-Switch Link Aggregations (S2SLA)
Note Link Aggregation requires an NNMi Advanced or NNMi Premium license.
Network administrators often need additional reliability and better resource usage between servers and switches. Many network administrators choose to use the Link Aggregation Configuration Protocol (LACP) because of its widespread use by network equipment providers. LACP is automatically negotiated after the IT engineer has bonded the ports on both sides of the server-to-switch configuration.
Network administrators often choose to use one of two types of switch-to-server connections to achieve the reliability and resource usage between servers and switches that they need:
- Option 1: Bond two or more ports on the server and connect them to the same number of ports on the switch. If a port on either the server or the switch fails, the backup port is activated.
- Option 2: Bond both the server and switch to provide the aggregate total bandwidth of all the ports in the aggregation.
NNMi provides a Discovering Server-to-Switch Link Aggregations (S2SLA) feature to help you manage switch-to-server connections. To ensure that NNMi can properly discover S2SLA information for a node, complete the following tasks:
- By default, Linux does not install its SNMP agent package, Net-SNMP. If Net-SNMP is missing from yourNNMi management server, you must install it.
-
The bonding interface on Linux can assume the MAC address of one of the aggregated interfaces, but it does not have to do so. The bonded interface can have a MAC address that does not belong to any of the server's interfaces.
Tip All interfaces in the aggregation use the same MAC address. A walk of the SNMP interfaces table returns the same MAC for the aggregator and aggregated interfaces. The shared MAC is used in outbound packets. The access switch's FDB table show this MAC as being heard over the switch's aggregated interface.
To view the original MAC addresses, use the following command:
cat /proc/net/bonding/bond0
