The tmnxLldpPortCfgTLVsTxEnable, defined as a bitmap,
includes the basic set of LLDP TLVs whose transmission is
allowed on the local LLDP agent by the network management.
Each bit in the bitmap corresponds to a TLV type associated
with a specific optional TLV.
It should be noted that the organizationally-specific TLVs
are excluded from the tmnxLldpPortCfgTLVsTxEnable bitmap.
LLDP Organization Specific Information Extension MIBs should
have similar configuration object to control transmission
of their organizationally defined TLVs.
The bit 'portDesc(0)' indicates that LLDP agent should
transmit 'Port Description TLV'.
The bit 'sysName(1)' indicates that LLDP agent should transmit
'System Name TLV'.
The bit 'sysDesc(2)' indicates that LLDP agent should transmit
'System Description TLV'.
The bit 'sysCap(3)' indicates that LLDP agent should transmit
'System Capabilities TLV'.
There is no bit reserved for the management address TLV type
since transmission of management address TLVs are controlled
by another object.
The default value for tmnxLldpPortCfgTLVsTxEnable object is
empty set, which means no enumerated values are set.
The value of this object must be restored from non-volatile
storage after a re-initialization of the management system.
