Folks,

Most of the time, the Internet nowadays makes it very easy to find information, but I’m struggling to find good documentation for EOS. I’m sure that there must be comprehensive, well structured documentation written for this kind of software, but it seems hard to find.

I have access to the user manual for EOS and the articles on this site, but I’m still missing information that ought to exist somewhere. In particular, I’m looking for a good source of information about the meaning of system messages, such as – for example

%STRATA-6-VXLAN_PORT_TO_NEXTHOP_OVERFLOW […]

Is there someone here that can point me in the right direction?

/David

Hi David,

The manual for the EOS software can be found using the following link https://www.arista.com/en/um-eos.
Also you can find the meaning of system logs in the EOS SysMsgGuide file that comes with every EOS release.
For example the SysMsgGuide for EOS 4.19.1F can be found in the following location:
https://www.arista.com/en/support/software-download — EOS — Active Releases — 4.19 — EOS-4.19.1F
— EOS-4.19.1F-SysMsgGuide.pdf

For your specific question you can check the show platform trident vxlan port-to-next-hop command to understand if the table is in an overflow state.

Whenever a port has more than one next hop, we will print a syslog indicating that the port-to-next-hop table is in overflow state. When the number of next-hops again goes back to 1 for that port, we again print a syslog indicating that the overflow status is resolved.

Hope this answers your question.

Thanks Alexandru, the SysMsgGuide is exactly the kind of manual that I’m looking for at the moment.

Hello David,

Trident platform has a hardware table to display “port-to-next-hop” mapping.When there are more than one next-hop for Vxlan on an interface, it results in overflow and this log is printed.
You can find more information about logs from our Sysguide.You can download Sysguide from our website.
 
Once on downloads page, click on the desired EOS version folder and there you will see Sysguide attached.

 

Thanks, Harshita!

Unfortunately, I can’t find any documents called ”Sysguide” in the software download area. Perhaps, you are referring to the same SysMsgGuide that Alexandru has written about? If not, I’d appreciate it if you can help me with a more specific link .
