- * Run command line trap receiver and print incoming PDUs. Loads MIBs
- * as specified, and converts to/from names for loaded MIB data.
- * It also prints loaded trap names and descriptions when the
- * corresponding traps are received.
- *
- * [-c] <community> - community String. By default "public".
- * [-p] <port> - remote port no. By default 161.
- * [-m] <mibs> - The mibs to be loaded.
- *<img SRC="images/v3only.jpg" ALT="v3 only"> [-e] <engineID> - The V3 engineID
- * [-u] <username> - The v3 principal/userName
- * [-a] <autProtocol> - The authProtocol(MD5/SHA). Mandatory if authPassword is specified
- * [-w] <authPassword> - The authentication password.
- * [-s] <privPassword> - The privacy protocol password. Must be accompanied with auth password and authProtocol fields.
