[SNMP4SDN-10] Can not support PortID subtype: Interface name

Thu, 19 Oct 2017 21:25:16 +0000

Three switches on which the PortID subtype is Interface name are used in my experiment, and the connection between them is as follows:
switch1(GigabitEthernet1/0/1,177.0.0.104)-------~~(GigabitEthernet1/0/1,177.0.0.105) switch2 (GigabitEthernet1/0/2,177.0.1.105)~~-------(GigabitEthernet1/0/1,177.0.1.106)switch3

Firstly, I configure the SNMP protocol and LLDP protocol on three switches correctly.

Secondly, I use command snmp4sdn:readdb to read device information of the three switches, and the information is as follows:
MAC,IP,SNMP_Community,CLI_Username,CLI_Password
06:DF:44:64:01:00,177.0.0.104,public, ,
06:E4:80:8E:02:00,177.0.0.105,public, ,
78:74:6B:FE:03:00,177.0.1.106,public, ,

The result after executing this command is as follows:
MAC address (sid) IP address SNMP community CLI username CLI password
00:00:06:e4:80:8e:02:00 (7578479100416) 177.0.0.105 public
00:00:78:74:6b:fe:03:00 (132441423348480) 177.0.1.106 public
00:00:06:df:44:64:01:00 (7555994878208) 177.0.0.104 public

Thirdly, when I use command snmp4sdn:topodiscoverswitches to discovery the three switches, the error java.lang.NullPointerException occurs when executing this command.
