This is the error when i try to load a MIB file :

Could not parse the file C:/AdventNet/Simulator6_0/mibs/MediaLinks/MD8000/MD8000-PRIVATE-MIB.mib The error occured at the line no: 96 ,column: 35The identifier should not start or end with number or special character.

The lines in the mib file is as follows:

mdChassisType OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"xyz."
::= { mdChassis 3 } error causing line

I'm hoping the syntax is correct ,then why this error?
