Hello,
We have in lab two connected x460 (EXOS 16.1.4.2) switches with MPLS/LDP/VPLS between. When I enabled logging for event MPLS.LDP.InternalExcept I can see following messages:

Feb  2 11:28:06 10.1.2.1 0x00002301-48 (0) LDP SC Entity Manager received a socket error indication. Error code = 22
Feb  2 11:28:21 10.1.2.1 0x00002301-48 (0) LDP SC Entity Manager received a socket error indication. Error code = 22
Feb  2 11:28:51 10.1.2.1 last message repeated 2 times

Could not find explanation for this error. What does it mean?
Regards,
Anatoly

Hi Anatoly,

I see that there is an internal CR for this message. Can you open a case for this to make this CR as Reported by Customer?

Hi Ron,
Unfortunately, our old X460s in lab don't have Extreme support. Our company doesn't buy support for test equipment.

One more piece of information I missed previously - this error is seen when LDP is down between switches.
