Hello,
Is it possible to gather information about port-channel member interfaces via API?
Hello,
Try same ifPhysAddress and parse their ifType the one with ieee8023adLag is lag and others its members.
Hello,
I’m not sure that I understand you properly. Could you please explain more detailed?
How exactly? For example I have stack of 2xCat9300, here is output with mac addresses -
mgm-core#sh interfaces port-ch3 | incl Hardw
Hardware is EtherChannel, address is 0045.1d1b.4db7 (bia 0045.1d1b.4db7)
mgm-core#sh interfaces te 1/1/3 | incl Hardw
Hardware is Ten Gigabit Ethernet, address is 0045.1d1b.4db7 (bia 0045.1d1b.4db7)
mgm-core#sh interfaces te 2/1/3 | incl Hardw
Hardware is Ten Gigabit Ethernet, address is 0045.1d1b.4737 (bia 0045.1d1b.4737)
mgm-core#
I have port-channel and one of physical ports only with the same mac addresses. But second interface in this port-channel has different hw address.
And additionally looks like libre can gather information about port-channel members from nexus devices.
Hello @zombah,
Sorry for the late reply
We have tried your suggestion. However, ifType on a member interface shows ethernetCsmacd, which is expected, and on the port-channel interface, it shows as propVirtual, which also quite ok.
The only problem, for now, is to determine the member interface relationship to the parent port-channel member through API, see the example below:

Is there a way to get this relationship information using API?
@zombah here is how the correlation looks from SQL perspective:
MariaDB [librenms]> select ifIndex from ports where device_id=224 and ifName='Po4';
+---------+
| ifIndex |
+---------+
| 5004 |
+---------+
1 row in set (0.00 sec)
MariaDB [librenms]> select * from ports_stack where device_id=224 and port_id_high=5004;
+-----------+--------------+-------------+---------------+
| device_id | port_id_high | port_id_low | ifStackStatus |
+-----------+--------------+-------------+---------------+
| 224 | 5004 | 10104 | active |
| 224 | 5004 | 10604 | active |
+-----------+--------------+-------------+---------------+
2 rows in set (0.00 sec)
MariaDB [librenms]> select ifName from ports where device_id=224 and ifIndex=10104;
+---------+
| ifName |
+---------+
| Gi1/0/4 |
+---------+
1 row in set (0.00 sec)
MariaDB [librenms]> select ifName from ports where device_id=224 and ifIndex=10604;
+---------+
| ifName |
+---------+
| Gi2/0/4 |
+---------+
1 row in set (0.25 sec)
Let me know if I need to provide more details.
Looks like get_port_stack endpoint answers our questions however it would be great if you can give some hint how to query this endpoint based on port_id_high column.
Thank you in advance
Hello, As you can see ifPhysAddress is same, so you can try figure relation using it.
I didn’t know get_port_stack exist, this endpoint look like best method for LAG members, as i understand it port_id_high is LAG port and port_id_low it’s members.
You can get full list’s list_devices, get_port_stack and get_all_ports then join them same way you do for sql and query resulting dict specific device and port.
