Object

scalar r/w SNMPv2-TCDisplayString

Provides a mechanism to change or enable/disable the
read-write community name used to by SNMPv1/v2 to read and set
SNMP MIB parameters, however, for security reasons the configured
value is never displayed. The strings 'Enabled' and 'Disabled'
have special meanings and cannot be used as rwCommunity string.
     Reading:
       String 'Enabled'  - A read-write community is configured
       String 'Disabled' - The read-write community is disabled.
     Writing:
       String 'Disabled' - Disable the read-write community
       Otherwise the written string becomes the new read-write
       community (this implies that the read-write community is
       enabled if it was earlier disabled.
     Note that enabling the read-write community via SNMP is only
possible from SNMPv3.

Syntax

SNMPv2-TCDisplayString

Source: SNMPv2-TCDisplayString
Base type: OctetString
Display format: 255a

Type Description

Represents textual information taken from the NVT ASCII
          
character set, as defined in pages 4, 10-11 of RFC 854.
          
To summarize RFC 854, the NVT ASCII repertoire specifies:
          
  - the use of character codes 0-127 (decimal)
          
  - the graphics characters (32-126) are interpreted as
    US ASCII
          
  - NUL, LF, CR, BEL, BS, HT, VT and FF have the special
    meanings specified in RFC 854
          
  - the other 25 codes have no standard interpretation
          
  - the sequence 'CR LF' means newline
          
  - the sequence 'CR NUL' means carriage-return
          
  - an 'LF' not preceded by a 'CR' means moving to the
    same column on the next line.
          
  - the sequence 'CR x' for any x other than LF or NUL is
    illegal.  (Note that this also means that a string may
    end with either 'CR LF' or 'CR NUL', but not with CR.)
          
Any object defined using this syntax may not exceed 255
characters in length.
