SLX 18.2r interpreting and troubleshooting sh port-channel x command

jhmaest — Sun, 19 Jan 2020 04:27:23 GMT

The command output is as follows. Am running SLX-OS 18r.2.00ab

I’ve been unable to find the cause of the “sync:0” in the member port. Can anyone suggest how to find the root cause and to get more information on this sync condition?

SLX# show port-channel 10
LACP Aggregator: Po 10
Aggregator type: Standard
Admin Key: 0010 - Oper Key 0010
Partner System ID - 0x8000,01-e0-52-00-08-3b
Partner Oper Key 0049
Flag * indicates: Primary link in port-channel
Number of Ports: 2
Member ports:
Link: Eth 3/10 (0xC614000) sync: 0
Link: Eth 4/10 (0xC814000) sync: 1

From the SLX side, could you can run the following commands? This will check the condition of the member interfaces and also the supposed configuration.

Also what about the partner device? Are all ports up and healthy?

show port-channel summary
show interface port-channel 10
show interface ethernet 3/10
show interface ethernet 4/10
show media interface ethernet 3/10
show media interface ethernet 4/10
show media optical-monitoring interface ethernet 3/10
show media optical-monitoring interface ethernet 4/10

show running-config interface Port-channel 10
show running-config interface Ethernet 3/10
show running-config interface Ethernet 4/10
show logging raslog | include 3/10
show logging raslog | include 4/10

The “0” means that that port is either not online or the end device is not configured to send the same LACP parameters to indicate that it's talking to the same logical device. As a result, the SLX is not able to bring both ports online to be in the same port-channel.

Can you try disabling 4/10, then see if 3/10 comes online? If it does, can you check if you get the same below parameters?
