ctAgentDhcpServerExcludedAddressRangeCreate – CT-FASTPATH-DHCPSERVER-MIB

Object

scalar r/w SNMPv2-TCDisplayString

It sets the IP address-ranges(from low to high) that a
DHCP server should not assign to DHCP clients. Each time 
this MIB object is set successfully, one excluded range 
of IP address will be set.
It is given in format - start and end IP address 
separated by '-' and terminated by ';'.
One example would be - 192.168.36.1-200.1.1.1;  .
This sets one excluded range of IP address,which
starts at 192.168.36.1 and ends at 200.1.1.1. 
If only start IP address is given,
end IP address is assumed to be equal to the start IP
address. Get operation on this MIB object returns a 
null-value, as for the purpose of viewing the 
exclude-address ranges, the user should perform the 
traversal of ctAgentDhcpServerExcludedAddressRangeTable.
For this reason the get operation on object 
ctAgentDhcpServerExcludedAddressRangeCreate becomes insignificant.

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.
