This variable identifies a Banner string section in the Banner content.
The Banner content is limited to 2000 characters. Content is divided into 13 indexed sections. Each section contains 160 octets, except the last used section which can contain less than 160 octets. Once a section of the Banner string contains 160 octets of data, the user can write to the next index. Overwriting is not supported. To delete all Banner content, use the rlBannerMessageClear MIB.
