Step 2.2: Parts of Network to Discover
Step 3: SNMP Read Community Strings
Read Community strings are used to retrieve SNMP data from the customer network.
Without the community strings we cannot retrieve retrieve performance criteria (CPU,
interface) from devices.
If your customer does not want to give you the community strings, a workaround is to
ask the customer to create temporary Read community strings that expire or will be
deleted when ELAT has concluded data collection. Once the community strings expire
or are deleted, the community strings in the dataset will no longer be valid and will
not compromise the customer’s network. We recommend "public" or "Avaya" as the
Read community strings. Please have the customer verify that the community strings
will expire after data collection has concluded.
