Like its sibling aOct1, this is a demonstration OCTET STRING object from a tutorial MIB, with the file's own comments flagging its hex-string default value as deliberately invalid ASN.1 (using lowercase hex digits and letter) to illustrate a common authoring mistake. It has no real operational meaning on an actual device; its purpose is purely to teach how an OCTET STRING object is declared. A get of aOct2 in this teaching MIB would return the raw test bytes configured as its default, such as 0a 23 bc, used to demonstrate the hex-string default syntax.
