When you configure discovery for network devices, you can specify system attributes, such as name, description, and object ID (OID) to include or exclude from the discovery. The attribute fields allows for wildcard pattern matching.
Wildcard pattern matching is done from left to right, one character or basic wildcard pattern at a time. The pattern and the incoming string must match exactly, so for example, the pattern abc does not match the string abcd. Compound patterns consist of basic patterns separated by an ampersand (&) or a tilde (~). If the first character of a compound pattern is an ampersand or tilde, it is interpreted as if there were an asterisk at the beginning. For example, the pattern ~*[0-9] matches any string that does not contain a digit. A trailing ampersand can only match an empty string, and a trailing tilde indicates “except for an empty string.”
Spaces are significant characters, and are subject to matching.
For examples of wildcard patterns, see “Wildcard Matching” in the Network Device Discovery Settings topic in the Operations Guide.
