Cisco 2960S - Delayed communication

joshhboss · ‎03-12-2021

So honestly I’ve been using Cisco 2960s. That I’ve found on eBay for a good price and I love them for camera networks but I’ve also been using them for events.: and in these events they have wired connections to clover devices, now during the last two events they’ve mentioned some delayed printing on the network. All devices on the same vlan. I wrote it off as a clover thing at first but then I noticed while setting up my last camera network. Even after all the cameras were address. I would try and log into them one by one and notice that it did actually take a few attempts of getting to web GUI for the camera to open. I think tried pinging the cameras before opening the GUI and the same behavior. First few packets wouldn’t go right through.. is there something I’m doing wrong with these setups. Or are these switches just to old.
switch ports are always

sw access vl 100

ip dev track max 1

Nothing else.

Hello,

try and set the mac address table timeout to something different than the default 360 seconds (e.g. 86400 seconds/24 hours):

2960S#conf t
2960S(config)#mac-address-table aging-time 86400 vlan 100

joshhboss · ‎03-13-2021

Thank you so much for responding. I already applied the command to my switches on the job I’m working on now.. and going to see if I notice an improvement. I’ll jump back on later this evening

joshhboss · ‎03-23-2021

About the mac aging, i had a thought.. Im actually going into an event today that i was going to try this but it occurred to me that there are many access points there where they have hand helds. and they are moving around connecting to different access points to get on the vlan 100.. will this aging cause a mac flap that could shut down ports.?

joshhboss · ‎03-13-2021

@balaji.bandi Check it out..

it does feel like it is working a bit better with the commands for mac address aging 86400

Hello,

good to know...however: define 'a bit better'...

joshhboss · ‎03-13-2021

instant response from the cameras on my network (254) whenever i re initiate a connection. (open the web browsers login to the camera) i thought it was odd when this client mention the delay when printing at the event. but i did notice a delay everytime i tried logging into the cameras.(different location different switch.. but same model)(i basically only use 2960s 48port)(i know a little older)... at first when i noticed it on the gui. i then tried pinging first before launching the camera window. and first 3 to 4 packets would not go through..

i also ran a ping test with 'pinginfoview' (pinged 20 cameras continuously) and notice i was dropping packets here and there. but so far my test is running with over 4000 pings and no drops..

joshhboss · ‎03-13-2021

i noticed as i was just checking connectivity to the cameras from the switch that with several of the first pings there is a 1000ms ping reply.. this is after the mac address aging to 86400.. Could this be the device responding poorly..? i mean after that.. the communication is incredible.. but its that initiation..

Hello
TBH you mention events but what is that in relation too?
Then you mention delay in printing -
FYI printers can go to “sleep” if they are not used and most drivers have a sleep mode timer that can be disabled or extended if this is what you are relating to in your OP regards events?

You could also make sure all access ports have spanning-tree portfast applied -

I would say that would tweaking the the cam table ageing for the whole vlan for 24 hrs just for printers going into sleep mode isn’t appropriate try disabling IPDT instead and implement the above suggestion then test again.

Im sorry, I did mention in my original post that they were clover devices not specifying what they are. They are like POS devices. Tablets and Printers both made by a company called Clover. issue they had was a delay printing the drink or food order from tablet to kitchen or bar printers.

Hello
Have you tested with stp portfast enabled and with IPDT turned off?

Also why specifically apply the power consumption, Would suggest first let the devices auto negotiate its power with the switch then when you have a stable connection manually tweak

i did start using stp portfast. and ive found that ipdt has been very helpful, i actually use it all the time, is it not recommended? i just into the habit of the power consumption because a few times when i had 48 ports (2960s - 370Watt) for some camera networks.. and when id go over the 24 ports the 25th camera and on would not work. so i learned about the power consumption and i was able to set it up to use all ports. ever since i just do it.. also not recommended?

and at the event now id like to add. the astro turf that they are using is causing static electricity all over the place.. im getting shocked like crazy to everything around me.. the switch is not on the astro turf but alot of the cables are running on them to the bars (where the clover tablets and printers are)

Hello
What i suggested was for trouble shooting your problem it wasn’t meant to be a permanent solution I would like to say though using features just because they have worked in the past isnt recommended
Regards ipdt unless you have statically ip assigned end hosts then i don’t think it would be applicable to you here as by default dynamic arp inspection (DAI) is also enabled with ipdt so ipdt would be used only against arp that dai is able to check unless that is you have dhcp snooping enabled for dhcp end hosts.

Again the power consumption was only a suggestion so if you know the exact pw requirements for your poe devices then all good however if the switch fails after a certain amount of poe devices are attached when power is auto negotiated and it doesn’t do it when you manually set it then it could be either a good or bad sign as it may indicate the hosts are not being supplied enough power or that your switch supply isnt adequate for those poe hosts.

Stp portfast negates each port going through the stp process before it’s allowed to forward traffic plus negates stp transition whenever the port goes up/down

So all the above as ive stated is just a suggested approach to TS your problem.

Lastly I’m no electrician but static electricity around network devices and peripherals isn’t really a good idea!
