ya maxsize is given for autogrowth

What are the size details for the log currently?
Do you have any long running transactions?

If you want to move the existing t-log file to different location then, follow the below steps:
1. Run ALTER DATABASE command and change location of ldf file
2. Take database offline
3. Move the physical file from old location to new location.
3. Bring database online

You can also try to add second log file to your database


USE [master]
GO
ALTER DATABASE [DB_NAME] ADD LOG FILE ( NAME = N'second_log_file', FILENAME = N'D:\LOG_FILES\second_log_file.ldf' , SIZE = 1024KB , FILEGROWTH = 10%)
GO

USE MASTER
GO
DBCC FREESESSIONCACHE WITH NO_INFOMSGS
GO
DBCC FREESYSTEMCACHE 'ALL'
GO


and how does it will help to manage the log space ?

you are just adding trouble to existing issues

If not, you can try this

USE MASTER
GO
DBCC FREESESSIONCACHE WITH NO_INFOMSGS
GO
DBCC FREESYSTEMCACHE 'ALL'
GO
USE (YOURDBNAME)
GO
DBCC SHRINKFILE (N'LOGFILENAME', 0, TRUNCATEONLY)
GO
DBCC SHRINKFILE (N'LOGFILENAME' , 1024)
GO



Well, I suppose that you can try that, but since none of those will help in the slightest with a full transaction log and may in fact make the scenario worse, I personally would recommend that you don't try any of those commands.
