SG200-26P QOS Stats

                   I purchased this switch as an affordable way to deploy POE and to verify QOS marking if the need arises.
I have connected NEC phones and have confirmed via Cisco 2960's that the phones are marking EF (DSCP 46) correctly.  I then replaced the 2960 with the SG200.
I am attempting to see the DSCP Markings statistics increase during phone conversations.
Using the guide I chose the port in question and attempted to see Queue 4 for both "Set1 and Set2" (not great explanations as to what those are). In any event Queue 4 "total packets" is not displaying hits.  Before I cleared the counters there were some numbers in the total packets column but not while on a call.
My question are, will the switch only show hits against this querry if there is contention?
I get the set 1 and set 2 dirrences but then you need to chose a "drop precendence" too.  Not sure why this is required or the differences.  You would think queue 4 in this example would always be low drop precedence?
I simply want to ensure packets are getting marked to be forwrded by my RTR. I need to do this in case my MPLS provider does not honor the markings. The Branch RTR is not controlled by me so it's important I have some insight as to the marking as they leave the phone.
Thanks!

Hi Tom,
Thank you for your suggestions.
I did try and mark the packets right on the port as I set the port with the phone hanging off it to cos5. I then changed the switch from trust dscp to cos but the stats still wouldn't budge.
I will try and trunk today and leave the phone vlan as vlan 1.  I'll create a dummy vlan behind it that will go unused (great idea!).
I did also try "smartport" but am not sure I had it configured 100% correctly.  With smartport it tagged 2 of the 4 phone ports as ip phone / PC but not the other 2 so I don't trust it. I also tried to tag the port with the macro "NEC" phone but the switch wouldn't allow the change so again there must be something I'm doing wrong there (whew).
Hopefully the Trunk will work
Thank You very much!  Gary

  • SG200-26P + SF200-24P, LAG? Trunking?

    I'm not a network person by any means and have no problem admitting that. That's why I'm here.
    I have a SG200-26P that is already configured and working properly. It is connected to an ASA5505 that is acting as the DHCP server. We currently have 3 VLANs: 10, 20 & 40.
    We are adding in a SF200-24P and I wanted to LAG & Trunk (I think that's the correct terms) to the 26P and the VLANs would go across both switches. I set up the LAG through the GUI on both devices with GE25/GE26 on the SG200-26P and GE1/GE2 on the SF200-24P as the LAG ports. When I connect them together I can not get an IP address, nor can I ping the 26P from a device connected to the 24P (after setting a static IP to just be able to access the GUI on the 24P).
    SG200-26P = 192.168.1.3
    SF200-24P = 192.168.1.4
    Thanks for any help you can provide. I'm sure this is actually a simple setup but I can't figure it out.

    Hi MHPL, you're correct a LAG and trunk is accurate. When you think about a LAG think of it exactly the same as a single link. You must config it like any singular port and you will observe when configuring the VLAN properties that there is an option for the LAG.
    Moving past that, there are 2 types of LAG, static and dynamic. I recommend that you use static LAG where each side does not use any protocol to negotiate the LAG. So when you go to the port management -> LAG setting simple add the port and click apply (do not click LACP) and make the same configuration on the other switch and connect them. Just ensure that the switches are essentially identical.

  • Firmware upgrade SG200-26P from oldest version.

    Hello !
    I have Switch SG200-26P.
    Firmware version: 1.1.2.0
    Boot Version: 1.1.0.6
    Is it possible make upgrade to the latest firmware version 1.4.0.88 directly or I should make intermediate upgrades ?
    Should I upgrade Boot Loader and if yes, where I can find it because I saw only Firmware for downloading ?
    Thank you in advance.

    Hello, 
    I'm sorry but I was reading the answer and I don't think it is correct.
    On the SX200, SX300 and SX500 switches, you will need to upgrade the boot code once you get to 1.3.5 otherwise you won't be able to upgrade to the latest firmware afterwards.
    The reason for this is that the boot code will modify the flash memory on the device and get it ready for higher firmware versions.
    Here is the release notes from 1.3.5:
    http://www.cisco.com/c/dam/en/us/td/docs/switches/lan/csbss/sf20x_sg20x/release_notes/R_1-3-5_RN.pdf
    Within this document you will find the following information:
    Before upgrading to version 1.3.5, the boot loader also needs to be updated. If version 1.3.5 is installed using the original boot loader, the file system will not be upgraded, and in the future the user will not be allowed to upgrade to versions higher than 1.3.5.
    I will recommend to step up the upgrade, as follows:
    1.3.0.6.2, 1.3.5.58 (and boot code via TFTP), then 1.4.0.88.
    I hope this information is helpful.

    Are 16900 divided between two or more ports?
    I dind´t find the relevant answer on the switch specifications.
    Can anyone help?

    Hi Minitrucker,
    SG200-26P is 802.3af compliant but from what I manage to read Ubiquiti UAP-LR is not 802.3af/at compliant, correct me if I am wrong as I did not really find the datasheet for your specific AP.  This would mean that the AP would need the injector or specific switch rather than any. As it uses non standard PoE.

  • SG200-26P question

    I have a SG200-26P which I would like to have three interfaces COMPLETELY segregated from the rest of our network.. I though by using VLANS I could do that.. but the three interfaces I included in the VLAN and still communicating with the rest of the network.. Is there something I am doing wrong or can this not be done??

    Hello, 
    I'm sorry I didn't answer before but I was unavailable.
    After reviewing you configuration I'm puzzled as to why it is not working correctly.
    I can only give you a few recommendations to see if they help.
    1- Make sure there is only a single port connecting your SG200 with the watch guard.
    2- Make sure all the ports on your SG200 are configured with a single VLAN as untagged.
    On your watch guard, if you have both Vlans configured, make sure that inter plan routing is disabled.
    Try this and let us know what happens.

  • SG200-26P not powering three access points.

    Hello,
    I just purchased a Cisco SG200-26P to power three Ubiquiti UAP-LR-3 UniFi AP that are going in a new small network. I added the three AP’s to port 1, 2, and 3 and they are not powering up off the POE switch. I got into the switch and I don’t see anything that stands out for them to not power up. The AP’s work powered up with POE injectors. 
    Thanks,

  • Disable PoE ports SG200-26P

    I am thinking of buying a SG200-26P switch and have a few questions:
    Is it possible to disable the PoE function on the 12 PoE ports?
    I need al the ports but only 6 with PoE.
    What happens when you connect a non PoE device to a PoE port?
    Thnx Chris
    Sent from Cisco Technical Support iPad App

    Hi Chris,
    In Regards to your questions:-
    Is it possible to disable the PoE function on the 12 PoE ports?
    I have never played with the Cisco Linksys kit.
    I know on the Cisco 3550's you could use the "no power inline" or "power inline never"
    What happens when you connect a non PoE device to a PoE port?
    A self test process is run, known as SDP(Signature detection process)
    Before a POE switch or midspan (known as a PSE, for power sourcing equipment) can enable power to a connected IP camera or other equipment (known as a PD, for powered device), it must perform a signature detection process.
    Signature detection uses a lower voltage to detect a characteristic signature of IEEE-compatible PDs (a 25kOhm resistance).  Once this signature has been detected, the PSE knows that higher voltages can be safely applied.
    Here is a good link on PoE:-

  • SG200-26P Fan

    I would like to cut the noise from my SG200-26P. Any fan suggestions to replace the stock fan with?
    Can anyone tell me the size of the original so I can look for an alternative?
    Regards Chris
    Sent from Cisco Technical Support iPad App

    Hi Chris, removal or replacement of the fan will void the warranty of the switch. This switch has a limited lifetime hardware warranty. So you  will waste your investment for a $20 component if something goes bad with the unit.... If you feel your fan is faulty, call the SBSC and open a ticket.

  • SG200-26P [FW-1.1.2.0] - Very High Response Time: 1000ms!

    Hello,
    Problem: New SG-200 26P Smart Switch with Latest Firmware - Very High Responce Time 500-800ms
    We've a EdgeMarc 4500 Router with 10 VPN tunnels to 10 brach locations. SG-200 26P Smart Switch is connected to 7 Servers (2 Terminal, SQL, and Other) All locations have 50MB Download and 20MB Upload speed from Verizon FiOS Internet service.
    As per the SolarWind tool, the response time of this switch is around at 500ms. At the same time, the EdgeMarc 4500 router response time is around 40ms and less.
    We've 60 desktops remotely connected to our SQL Server database and 40 RDP Users via Remote Desktop. The configuration is same from past 3 years. But we change the switch from HP 1800-24G to Cisco due to some Connection Failures. For Connection Failures, we first suspect the old HP switch, but it's look like issue with EdgeMarc Router.
    Is this Response Time is normal? I attached two screenshots of both Cisco Switch and EdgeMarc Router Response Time from past 24 hours according to SolarWind tool. Any further advice would be greatly appreciated. Thank you.

    Hello Srinath,
    Thank you for participating in the Small Business support community. My name is Nico Muselle from Cisco Sofia SBSC.
    The response time from the switch could be considered as quite normal. Reason for this is that the switch gives CPU priority to it's actual duties which would of course be switching, access lists, VLANs, QoS, multicast and DHCP snooping etc etc. As a result of that, ping response times of the switch itself do not show in any way the correct working of the switch.
    I invite you to try pinging clients connected to the switch, you should be able to notice that response times to the clients are a lot lower than response times of the switch itself.
    Hope this answers your question !

  • Why would my SG200-26P loose its fixed ip?

    Hi there.
    I have 4 of these switches that seem to have lost their ips. They were fixed to 192.168.x.6,7,8,9 via the management inteface.
    It seems there was a power outage that reset most of the network. It was for less than 1 hr. Once things powered back up, it seems i can not get back into the switches. We have had a power outage event over the years before, and they came back up just fine.
    We cant ping that ip, or see the switch request DHCP on the network. These are off site, and I am trying to figure out how to get into it.
    We tried to set a secondary address for out nework to include 192.168.1.0 into the lan so IF it is set to .1.254 for some reason, that we can get to it. But i beleive all 4 switches which are on the same lan having the same address would give us conflict to not be able to get in or have a stable connection to them even with the subnet allowing access to .1.254
    Luckily, whatever state they are in, the LAN us up and running which is on a different subnet than .1
    So, must i do a truck roll? Will a reboot possibly help get them back up if they are rebooted 1 by 1?
    The only thing i can think of is that maybe they didnt get DHCP becuase they are connected upstream via their gbic fiber port? Maybe the fiber port isnt ready in time for the DHCP request from the switch?
    Any advice as to how this switch would loose its ip would be very helpful.
    Thanks
    Sam

    Hi Sam, it sounds like no one saved the running config to the start up config. Every change made to the switch does not automatically write to a memory. It behaves much like a computer. If a computer reboots with something in RAM, it is gone, it must save to the hard drive to keep coming back.
    The switch is most likely at a factory default state. If the switches connected to a DHCP network, they obtained an address from the DHCP server.
    Once you get back in to them and fix the switches the way you'd like, make sure to click the Save button at the top right and save the running config to start up config and reboot the switch to test it out.

  • SG200-26P and LACP

    Hi,
    I have two NAS. Each one from a different manufacturer, QNAP and Synology.
    The two NAS support LACP IEEE802.3ad but in this way QNAP loses 40% of the packets and Synology not work.
    With a Cisco Calatyst 3750 both NAS I work well. Do I have to do something in the SG200 to work?
    Thank you.

    Hi Tom,
    I use the mode   IEEE 802.3ad Dynamic Link Aggregation on the Synolgy and QNAP.
    Maybe I should use another way?

  • How to update boot file for SG200-26P

    I am new at this, and need assist in updating the sx200_boot-13506.rfb file into my switch.  I have downloaded the Boot and FW files to my computer which is connected to the switch, and updated the fw file by using the Upgrade page via HPPT/HP\TTPS and then used brose to find the fw file on my computer.
    However, HTTP/HTTPS does not allow upgrade of the Boot Code.
    For that I have to go to via TFTP, and here is the issue.  What do I put in for Server IP Address and Source File Name.  I have tried the computer IP for the first, and full route to the file for the second, but no go.
    Please help.
    I just bought this switch, and found out it out of support contract.

    Do you have a tarp server running on the computer?
    If you are using a windows computer download tftpd32 http://tftpd32.jounin.net/tftpd32_download.html
    Then make sure it is pointing to the directory the file is in, and it is using the interface that is connected to the switch.
    Place the computers ip on the upload page and the name of the file.
    If you need more help just reply

  • POE Problem with SG200-26P

    Having an odd situation with this switch. Set it up with two vlans and everything was gread for about 3 days then over the weekend something happened. One od the POE Phones a Cisco IP Phone 7960 started making an odd buzz sound while hooked up to port 13 on the switch. To aliviate the problem I switched the port to 14 for that phone. The buzz went away and the phone powered on. Started looking into the problem with the port and could not find any obvious problems with the port so deemed it to be a bad port. The next day the phone that was hooked to port 1 was randomly rebooting so looked into this port and while trying to find a port that worked found that ports 1-6 would not turn on the poe light on the switch and would not power the phones for a very long time without the phone rebooting. I did however find that ports 14-18 however work as they should. Is there something I am missing as to why  or how ports 1-6 are not turning on POE and could they be related to the problem with port 13? Any ideas on how to fix this problem. Currently on firmware version 1.3.5.58 and boot version 1.3.5.06. thank you for your time.

    David,
    This sounds like the switch is failing but I could not rule out a configuration corruption. I would back up the configuration, reset to factory defaults and test only the PoE functionality. If it works, recreate the configuration (VLANs, etc.) and confirm that PoE is functioning on all ports. If you still see issues at factory default settings, call support and open a case or return the switch to the reseller for replacement.

  • SG200-26p - DHCP

    Hi all,
    I just want to confirm something.
    Can the above switch be a DHCP server?
    Im limited on Virtual resource and cannot create another VM (at the moment) to be a DHCP server, this is in our testing lab so I cannot add a dhcp server to any of the current live boxes - it will effect our tests in some way.
    Thanks in advance

    thanks for the info.
    Fortunately I have a spare rasberry pi lying around.
    Will make use of that for DHCP :)
