System Type: EXOS or SwitchEngine ?

Leo_Bistmans1 — Fri, 29 Mar 2024 12:01:14 GMT

We noticed the show switch command on 2 different 5420s gave another System Type:

System Type: 5420F-48P-4XE-EXOS
System Type: 5420F-48P-4XE-SwitchEngine

A few of the Switchengine ones give us a headache doing tftp image upload ( 31 -> 32 ) as tftp times out.

download image 10.10.10.10 summit_arm-32.6.1.5-patch1-2.xos vr vr-def
Note: The inactive partition (secondary) will be used for installation.
Do you want to install image after downloading? (y - yes, n - no, <cr> - cancel) Yes

Downloading to Switch
Error: Failed to download image - tftp: timeout

1) what is the difference?

2) do we need to look for a exos 32 for the SwitchEngine type?

Hello!

As of 32.1, EXOS was rebranded to SwitchEngine when running on universal platforms (5XXX and 7XXX) series switches. They are exactly the same software, just a different name.

Regarding the TFTP timeout, that seems unrelated. I would try using a larger block-size to reduce the potential for TFTP timeouts (specify 'block-size 65000' at the end of the 'download image' command). Otherwise, it could be an issue with TFTP being blocked somewhere in the network, or some server issue, that is causing the timeout.

Hope that helps!

cli help said default block size is 1400,

but going big 65000 timed out as well.

So I tried small 500 and hoorai,

image get tftp'ed just fine!

Many thanks for te hints.

The misbehaving 5420 mentioned memory problems:

While another 5420 in the same rack has a lot more DRAM and this more free space:

Different memory sizes on the same type of switch?

I'm pretty sure the 48 port 5420s have 2GB of RAM, the 24 port 5420s have 1GB of RAM.
Regarding the logs, those are informational, but installation will complete regardless in a similar amount of time.

DRAM is not linked to the number of ports :
