The value of tmnxUserAccess specifies the type of access the
the user is permitted. To allow the user access to the console,
FTP or SNMP, set the corresponding bit in tmnxUserAccess. Reset
the bit to deny the access.
'li' access allows this user to access CLI commands in the
Lawful Intercept (LI) context. The 'li' bit can only be modified
from the SNMPv3 'li' context.
