### Description

```asn1
cmcIIIModbusSource OBJECT-TYPE
SYNTAX DisplayString (SIZE (0..64))
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"Source to restrict Modbus access.
It can either be a
specific hostname,
IP address, or a subnet represented as
IP/MASK (e.g. 10.10.10.0/255.255.255.0),
or IP/BITS (e.g. 10.10.10.0/24),
or the IPv6 equivalents.
The same source can be specified in several separate
entries (presumably with different access tokens),
and the first combination that matches the incoming
request will be selected."
