Deleted MSAP identifier before rxInfoTTL timer expires

[faslan88]

Bug description

IEEE Std 802.1AB-2005 Section 10.3.7 Page 40 LLDP local port/connection failure'
"If the local port or the connection to the remote system fails before a shutdown frame can be sent, the LLDP manager shall not delete objects in the LLDP remote systems MIB pertaining to information received from any MSAP identifier through that local port until the port is re-initialized or the associated rxInfoTTL timer expires."

Steps to reproduce the problem

I have tested this scenario in version (1.0.4) as below:

• Send lldp package including:
  *** Chassis ID Subtype = Locally assigned (7)
  *** Chassis ID = MyChassis-1
• Disable port
• Check lldpRemChassisID with SNMP query before rxInfoTTL timer expires

Expected outcome

lldpRemChassisID: MyChassis-1

Current outcome

lldpRemChassisID: NULL although rxInfoTTL timer does not expire.

Hi,

We are facing with the same issue. I think according to the standard, the code is not working as expected. lldpRemChassisID is removed before timeout, when MIB is requested after certain time (before timeout duration), it returns NULL. The value should be cleared after timeout
