Port status change on merkai Switch

[HaniAbuelkhair4]

I have two printers and each printer is connected to deferent swatch Meraki MS120-48LP

And these printers are losing the connections from time to time 

Both were working fine but now are not stable and the log i have the following 

I checked the cables from the meraki dashboard and its all OK 

I have other printers and all of them are ok but these two 

Any suggestion ?

Port status change	port: 41, old: down, new: 100fdx
Port STP change	Port 41 designated→disabled
Port status change	port: 41, old: 100fdx, new: down
Port STP change	Port 41 disabled→designated

Can you share the port configuration?

[HaniAbuelkhair4]

Here we go

[cmr]

Try forcing them to 100 full duplex.  We have some servers where the 1Gb cards sometimes need the port to be forced...

[HaniAbuelkhair4]

Will try that 

[alemabrahao]

looks well, have you tested it in another port?

[RaphaelL]

All your other printers are the same model and running the same firmware ? As cmr suggested , try forcing the speed and duplex. This could also be a Eco feature kicking in 

[PhilipDAth]

I'm going to bet it is an "eco" feature as @RaphaelL mentions.  I bet you'll find the port changes are related to how long it has been since the printer was last used.

[HaniAbuelkhair4]

How can i check the eco feature ? is the printer setting ?

By the way this is kitchen recite printer in a restaurant (Epson TM-U220B)

 

[alemabrahao]

Does this thermal Printer has a LAN port? Or does It connected to a PC?

[HaniAbuelkhair4]

It’s connected by Ethernet to the lan and they send orders to the printer 

[HaniAbuelkhair4]

I forced the port to 100base-T but again the same problem is happening again 

[PhilipDAth]

I've never seen a printer yet that lets you configure the eco Ethernet setting.

[RaphaelL]

I think I have seen IEEE 802.3az settings on some models of Lexmark. I could be wrong , will have to check tomorrow

[alemabrahao]

@RaphaelL, I have checked the datasheet and this Printer model does not support IEEE 802.3az. In my opinion, It can be a printer issue or the port issue.

[HaniAbuelkhair4]

Same iss

ue is still happening after forcing the port to be 100 100base-T and still getting same error 

[alemabrahao]

Any chance to test It on another switch?

[HaniAbuelkhair4]

I have two printers and each printer is connected to different switch as i have two switches

I am thinking to connect one printer to the Meraki MX directly and see 

will let you know
