Legacy PoE on SG200-08P?

Hi,
I saw the annoucement stating that "200 and 300 Switches now supports Cisco Pre-standard POE" available here:
https://supportforums.cisco.com/docs/DOC-18337
However, I cannot find the 1.1.1.8 firmware for the SG200-08P in the download center (latest is 1.0.1.0).
Does this mean this doesn't apply to the SG200-08P?
If it doesn't apply, any other switches with 16 or less all gigabit ports which support legacy PoE?
Thanks.

Hi
I noticed in CCA release notes two versions of the 200 series switches were not supported by Cisco Configuration Assistant . To me this means that these two switches are not using version 1.1.1.8
Have a chat to the good folk of SBSC, they can track down if the reason for the current software not being available for your switch.

Not that it's any consolation, but I also confirmed your finding.

Passing voice and data Vlans on Cisco SG200-08P help

Hello All,
I'm struggling with a configuration issue on the Cisco SG200-08P.
We are using the Cisco SG200-08P on a mobile cart that will go from class room to class room that will have computer and cisco Voip phone plugged into it. The issue is that each of our closets are in differnt VLANS ( 1 voice and 1 data....lets say data vlan 20 and voice vlan 2025 for conversation) and that we route to each closet.
It would be great if I could just create a generic data and voice vlan to dynamically pick up what the upstream switch has however, it seems that I've been unsuccessful in doing so.
So far I can pass the data Vlan no probablem. The upstream switch port is set to access port and a switch port access voice vlan (these are 3750x switches)
If the above is not possible I guess I will take what I can get. Should I just create data vlan 20 and voice vlan2025 on the Cisco SG200-08P and make a trunk port on the Cisco SG200-08P and a trunk on the 3750x? Is there an option on the Cisco SG200-08P to tag voice traffic?
I'm also concerned with VTP and I did not see an area in the Cisco SG200-08P to set that as a client and transparent mode.
Thanks for any help,
Dan

On a Catalyst switch, when a port is defined as a trunk without a vlan specified on the port, all vlan pass through the port. On a small business switch it is nearly the opposite. You must specify the vlans on the links. Additionally, ingress filter discards anything not associated to the port.
802.1q specifies there must be an untagged vlan which is the native vlan (of course you can make exceptions, tagging the default vlan..).
One thing I did in the past with a 2960, I made an LLDP network policy and it basically "provisioned" the downstream switch connecting link and voice vlan. That may be another idea for you.
Here's a link that may be useful-

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

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:-

Cisco sg200 Switch passive PoE support

Hi
I have a cisco SG200-08P switch. I would like to power a device (TP Link TL-WA901ND) that supports passive PoE.
However it seems that the SG200 series do not support this?
Am I correct in this assumption, and if so is there a workaround?
Thanks for looking Dave

Hi,
According to the data sheet (below link) the SG200-08P supports POE. So, it should be able to power up the AP.

SG200-8 port 1 disabled

I have an SG-200-8 which connects to a stacked pair of SG500-28P switches. It is powered by PoE from the SG500. From the SG500 the port appears Up, but at the the SG200 it is disabled and nothing I do re-enables it. I know the cable is good because I had a previous netgear switch hanging off it and working, also the power gets through.
I can only connect to the switch if I disable wifi and plugin a manually configured PC - DHCP doesn't get through to it from the SG500 end.
I have tried a second SG200 same problem. Have disabled RSTP/ STP thinking it might to relate to the fact that a PC connected to the switch also had a wifi connection to the same LAN, but. Don't know where to go next. looks like a bug?
Sent from Cisco Technical Support iPad App

Hi Simon, quite honestly this is not supported and should not be practiced. In the most technical point of view, it is actually a software exploit to try to use in this manner. The switch is a PSE (power sourcing equipment) not a PD (powered device). It is meant to supply power to a device, not receive power to operate.
The exploit I mentioned is because these units are designed to work with legacy POE standards. The switches should always be powered by AC connection. It is an exploitation in software because it is a false signature detection in an effort to power a PSE which is being sensed as a PD.
I would encourage you to use the AC power and avoid this practice as configuration scenarios and the unexpected behavior cannot be supported.

SG 200-08P config and firmware

Hi,
we just got 10 new devices with the actual fw 1.0.6.2.
Two problems were coming up ...
First: user and password ... The other SG 200 switches allow password with special characters like !? ... the SG 200-08 does not! That is not very helpful.
And we would like to have this fixed.
Second: After configuation of VLANs along with CDP an Cisco Phones we always had to restart the device to be sure the configuation change was applied. Otherwiese we were hunting problems that did not really exist. May be this could be fixed in a new version of the firmware, too.
Thanks ;-)

Thanks for the info. I was working off another post where someone laid claim to installing the 1.3.x firmware on their sg200 to enable SNMP protocols for Spiceworks Management software.
Does this mean there is no SNMP options for the SG200-08P switches?

SG 200-08p Wont upgrade firmware

I have a fleet of the SG-200-08P switches which are way behind on firmware. I went to upgrade them to the newest firmware available:
     "sx200_fw_1.3.7.18.ros"
After about a 5-7 minute wait, the web interface returned the message (tired multiple times):
     "Firmware Image download through HTTP failed. Wrong File Type."
I reset the router, same results. I went and installed the second most recent verson, "SG200-08x_FW_1.0.7.4.stk", which installed without any issues. Then tried the "sx200_fw_1.3.7.18.ros" file and again with the same result:
     "Firmware Image download through HTTP failed. Wrong File Type."
I then did a factory reset and tried again, same results. It seems that none of my routers want to use the .ros files, it preferes the .stk files. What am I doing wrong?
I'm accessing the upgrade feature via "Main Menu -> Administration -> Upgrade/Backup firmware" and have it set to:
X - via Http
X - Upgrade
X - Firmware image
Please HELP!!!

Poe881 Router and Cisco Inline Power (pre-standard PoE)

I have a number of 881 Routers and 79x0 IP Phones. These phones use "Cisco Inline Power", aka "pre-standard PoE". In other words, they are not compatible with standard 802.3af PoE.
It would be possible for me to install a daughtercard and DC adapter in the 881 routers and provide PoE to two of the ethernet ports. My question is whether the 881 (when equipped for PoE) will support Cisco Inline Power, or if it will only support 802.3af.
For reference, the 200 and 300 series Small Business switches support these phones with a software upgrade. See this link: https://supportforums.cisco.com/document/71841/200-and-300-switches-now-supports-cisco-pre-standard-poe-legacy-poe
Many thanks,

My question is whether the 881 (when equipped for PoE) will support Cisco Inline Power, or if it will only support 802.3af.
Hi Tom,
I don't have an 880 but I have a large fleet of 890 and all of them have PoE and I know these 890 support 802.3af easily.

Are 300 Series switches compatible with pre-standard PoE detection in old Cisco phones?

Are 300 Series switches compatible with pre-standard PoE detection in old Cisco phones? They don't seem to be (a 7902G won't power on when connected to an SF302-08MP with firmware version 1.1). Is any special configuration needed on the switch to enable this detection?

Please note that the 200 and 300 Series switches now support Cisco Legacy POE as of September 2011, allowing it to deliver power to 7960, 7940, and other pre-standard phones and APs. Details provided at the following link:

WAP371 clients constantly disconnecting/reconnecting

I have a new WAP371 with firmware 1.1.2.3. It's installed on an interior wall on the second floor of my three-floor house. It receives power over Ethernet from an SG200-08P switch. Each radio has a separate SSID. WPA-Personal is used on both. All traffic is in untagged VLAN 1.
Clients are will not stay connected for longer than a minute or two. The log shows an association, then after usually one or two minutes, the log shows a deauth with the message "Disassociated due to inactivity." Then the very next item in the log is another association from the client. This will persist for a minute or two, and then the cycle repeats, continually and forever. This happens even when there is activity, so "Disassociated due to inactivity" seems wrong.
Following various bits of advice here, I've tried:
various fixed frequencies
all bandwidth options
short guard interval yes and no
protection auto and off
frame burst on and off
fixed multicast rate auto and 54
removed 1 and 2 from legacy rate sets on the 2.4 GHz radio
set broadcast key refresh rate to 0
disabled TSPEC, scheduler, bandwidth utilization, client QoS, Green Ethernet
I'm at a loss to figure out how to fix this. It causes activity on the clients to sputter -- I'm seeing a fair number of retransmissions. Occasionally application connections, like streaming video, will reset. Help please?

Setup VLAN

Hello,
I want to setup VLAN to separate attached devices (will use a VLAN capabel WLAN accesspoint).
I am looking at the Cisco Small business products.
Like this: SG200-08P
This is my goal:
3 VLAN's: Internal, External, Guest
Devices connected to Internal can access External + Internet.
Devices connected to External can only access its own VLAN + Internet.
Devices connected to Guest are separated, they can only acess Internet.
I have a LAN Internet connection, with one IP address.
So I need NAT and Routing.
Do I need a VLAN enabled Router, or only a VLAN enabled Switch (Layer 2 / 3 / Smart)?
Can a Smart Switch act as Router?
Please advice me for Cisco - Products.

Hello Sam,
For your setup you will still want to get a router. Our Layer 3 switches do not do NATing or have any kind of firewall, so you probably would want something else in front of this on the edge of your network.
With a layer 3 switch it is possible to buy a router that doesn't do VLANs and still make it work. The RV series of routers would work well for this. All of them except for the RV016, RV042, and RV082 are VLAN capable. Even with those three you could set it up, it would just be a slightly different setup.
With a VLAN capable router you can do what is called router-on-a-stick, where all the VLANs are trunked up to the router, and it handles the Inter-VLAN routing. You can also set it up where the switch is everyone's default gateway, and it does the routing. In that case you would just have a point to point link between the router and switch, along with some static routes to make it all work.
So basically with a layer 3 switch you have some options, but you will still want a router for the NAT and the firewall features. It is possible to put a layer 3 switch directly on the edge, but only if you own enough public IPs for all of your devices.
Hope that helps a bit,

Cisco 300 series switches

hi all
Ive looked through some of the online content but dont see a definitive answer to my question about the physical size of the switches, are they all 19" rack mountable or desktop?
I look forward to a confirmation..

LJ,
P = PoE capable. On the 300 series, half of the ports can provide 15.4W, or all can provide half that.
PoE+ is NOT SUPPORTED.
MP = Maximum Power. This means that all ports can provide up to 15.4W. PoE+ is supported on some models only.
PP = PoE Plus. Can provide up to 30W on a single port. Note the maximum PoE budget for each switch. Also,
half of the ports can provide 15.4W, or all can provide half that - any extra power used by PoE+
MPP = Maximum Power and PoE Plus. This means that all ports can provide up to 15.4W - any extra power used by PoE+
According to the Data Sheet:
"Switches support 802.3at PoE+, 802.3af, and Cisco pre-standard (legacy) PoE. Maximum power of 30.0W to any 10/100 or Gigabit Ethernet port for PoE+ supported devices and 15.4W for PoE supported devices, until the PoE budget for the switch is reached"
The PoE+ models are brand new and are not widey available yet. I did a web search for SG300-28PP and found that at least a few online resellers have it in stock.

Cisco 300 series switches with 802.3at standard

I'm a bit confused as to which of the 300 series switches supports the 802.3at standard. According to the website, the SG300-28P supports it. But in the quick start guide for the 300 series, only the MP models (excluding the SF302-08MP and SG300-10MP) including the SG300-52P has it. Can someone give me a difinitive answer to this? Thanks!

PoE does no work for my SG 200-08P ?

Hi,
I've bought two SG 200-08P which have their 1-4 ports who can delivered PoE.
Whatever the PoE equipments I plug into those ports, it doesn't work.
If I plug a non PoE equipment in the 1-8 ports it's working fine.
I can log into the web interface of the switch, and when I go to "Port Management > PoE > Properties", I can see the following screen:
I don't know how switch the "Power" option to "On"...
I have the exactly same issue with a second and new SG 200-08P.
I've changed the firmware and I am now in the 1.0.6.2 version but I have the problem with the original version.
I also try to reset the switch several times, but it doesn't change anything.
Is anyone has a idea to what can I do or test ?
Thanks.

Hi Tom,
For now, I only try to connect differents Siemens IP phones (1 or 2 or 3 PoE classes) : OpenStage 20,
OpenStage 40 and OpenStage 60.
Those Siemens phones are working fine with other PoE switches like linksys, HP, catalyst, 300 series, Netgear ...
I've just noticed something interesting, in the "Status and Statistics > View Log > RAM Memory" menu :
When I clear the logs, only my computer is connected on port 8...
I'll try to find other PoE devices, to test with.
Regards.

SG-200-08P POE

Hi. I have a configuration whereby I use a SG-200-08P to power a SG-200-08 (no PSU connected) which in turn is connected to another SG-200-08 that is powered via PSU. It seemed to work but recently I've been getting connectivity issues. The Ethernet cable from the non PSU powered SG-200-08 to the PSU powered SG-200-08 is 100m. Are there any ways to configure these switches in order to resolve the connectiviy issues? Thanks.

Tom, many thanks for the response. I definitely think it's a power issue as the connection to my laptop keeps trying to connect/identify for a few seconds, then stops, then trys again/again and 100m is quite a long run from a switch that's powered by POE. Configuration is as follows:-
Router -->>--SG-200-08P -->>-- 100m -->>-- SG-200-08 (no PSU) -->>-- 100m -->>-- SG-200-08 (with PSU) -->>-- Laptop
My first thoughts were to attach the PSU to the SG-200-08 in the middle that's running off POE at present. Although because a power source isn't easily available there I was hoping I could perhaps divert more power to the port in the SG-200-08P that's powering the SG-200-08. Thanks. Guy
