Cisco Switches :: Two AP541Ns - Bandwidth Limited Through SF302-08P?
Aug 9, 2012
Just put in an SF302-08P switch with two AP541N's. Just a Comcast modem connects into the switch along with the two WAPs, nothing else. Speedtest through the cable modem with nothing plugged into it is 48Mbps. Then connecting a single laptop via the switch shows a speedtest of 33Mbps. Then with the two AP541N's plugged in and using the same laptop over WiFi, I'd consistently seen 10Mbps for downloading. But going right back to the cable modem directly showed me close to 50Mbps in a speed test.
Have factory defaults in all the Cisco devices, and poured over the settings and it looks like bandwidth limiting is disabled. Suspecting maybe it is for QoS and to optimize voice, but I see definite places in the devices where I could designate optimizing voice and those aren't enabled. Then started thinking with tweaking the wireless frequencies, but didn't want to do anything too unstable.

How do I make the following work with Cisco 302-08G ? I have a 4-port Cisco wireless/wired router that allows for a guest account. I also have Cisco SF302-08 that I bought so I could use its port/vlan mirroring capability. How should I configure the network, given the aforementioned equipment, so that I can get a single point sniff.
Assume I have two wireless clients, one using the "regular" wireless SSID, and the other using the "guest" SSID. I can see 192.168.1.x (regular SSID) and 192.168.169.x (guest ssid) on the internet side (one the same physical cat5 of the wireless router. So far so good. But, I would like to use 302-08 to actually allow the guest SSID/network comm cable)unicate with the regular SSID/network. For example, if I ping 192.168.169.x from 192.168.1.x, I would like to see a response. Can I make them communicate properly with the 302-08 ?? if so, what do I need to do ?? (I will also have wired clients tied into the 302-08..so its important that it be the central sniffer point).

I have the following setup using two SF302-08P PoE switches:
1st floor
=========
Switch #1 <-------> private network
<-------> public network
[Code].....
I have tried to make the config in switch #2 identical to switch #1, but something is still wrong. Is this most likely a VLAN setup problem, or what?

i am looking at quoting the SF302-08P for a client which will have three small offices interconnected via single mode fiber. I am planning on connecting them to a 3560 switch. Each office will have no more than 3 - 7942 phones. I reviewed the notes on this switch and it seems it should support this phone type without any issues.

I am in the process of preping our network for the installation of an IP Camera based security system on it will be running within VLAN 600 in our network, and management would prefer that general users are not even aware it is there.
16 Cameras will all be running off two SF302-8P Switches that will be uplinked to our Cisco 2960 Access Switches. Due to port limitations I need to daisy chain the two SF302 Switches.
ACCESS-302-CA-01 - Ge1 uplinked to Port on ACCESS-03 (Cisco 2960) On this switch Fe1-8 Need to be in VLAN 600 to communicated with the camera server which will be plugged directly into Ge2 on Access 302-02.
ACCESS-302-CA-02 - Ge1 Uplinked to Ge2 on ACCESS-302-01
Ge2 - connected to the Network Video Recorder.
I've defined the VLAN's in the switch and have VLAN 600 as Untagged for FE1-8.
how do I configure Ge1 and Ge2 on each switch to pass the appropriate VLAN conntent to the devices connected?

I'm wondering if anyone knows to set up the switch so that when I'm connecting via SSH, the switch doesn't prompt for a username if I supply one in the initial connect request? For example, we usually connect by typing something like the following at a command prompt:
ssh johndoe@10.10.10.10
Then the switch would prompt for a password. I've tried this on the Cisco SF302 but it still prompts for a username, and then the password.

I'd like to know if there's a command I can run to turn off paging on my SF302 switch. So for example, when I run the "show logging" command on the CLI, I'd like to it return all the results instead of prompting me to hit space bar or enter.

I have several SG300-10 and SF302-08P switches running with L2-mode, and after I upgraded their firmware to 1.1.2.0, they began to record the following logs every one hour.
- Severity: Warning
- Description: %COPY-W-TRAP: The mirror-config file is illegal due to failure of previous copy operation/s to mirror-config.Also I found that I didn't see the Mirror Configuration file on the Configuration File Table in the Configuration Files Properties page.

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?

I'm wondering if there is a way to prioritize traffic on the router's main WiFi over the guest zone or if there is a way to limit the bandwidth on the guest zone.
Ideally, I'd like to keep a locked primary WiFi for high-speed usage (I know, nothing it really ever secure) and an open guest zone for low-speed usage to whomever wants it. As far as I can tell, the DIR-655 doesn't support this kind of configuration.

I have a Cisco Aironet 1240AG Access Point and I am trying to setup a guest network that is secure and limited in bandwidth utilization. I see an option under security > SSID Manager on the web interface to select an interface of Radio0-802.11G, Radio1-802.11A or both. Can I put the guest network on the Radio1-802.11A and make it more secure/bandwidth limited or does this option not matter?

I have got a very basic/fundamental doubt.I would like to know how a bandwidth gets distributed in switches.for example consider a scenario where i have a coreswitch A and coreswitch B connected between each other througha a 1Giga Fiber now each of my core switche are connected to two edge switches through fiber links. all edge switches have giga ports. now if i connect a pc with giga link in th edge switch of coreswitch A and tansfer a file to a PC connnected to the edge switch in network B.how does the switch allocate/distribute bandwidth?

I have a SG 300-20 small business switch and I would like to restrict bandwidth by gateway ip address but not by physical port or LAG. On the web interface, I can only do bw limiting per port or lag. I want to do bandwidth limiting by the IP addresses that I assign to vlans that my hosts use as a gateway ip.

Does the SGE2000 supports NetFlow? I've checked the Cisco docs and also called Cisco support to which no one has been able to answer me.
Anyhow, just in case it doesn't support NetFlow, how to be able to set up something that would be able to check the bandwidth usage on each port?
I've got a problem where I think the SGE2000 switch is failing when I pump around 190~200Mbps through x2 of the ports (Server A on port 1=130Mbps and Server B on port 2=60Mbps) of Multicast traffic (UDP). I can measure the output from the Streaming servers that provide the multicast content, thats how I know the input to the switch and I know that there are no packets lost or any errors departing from the servers, yet when I increase server B to say 80Mbps, I get break up and all sorts of problems on the client end STBs and it is happening on the multicast content provided by Server A too which is a different source, so I'm 99.9% sure its a SGE2000 switch problem which is why I'd like to monitor it somehow.

I am trying to use a SF302-08P switch to connect a conference phone (Cisco 7937) to my infrastructure. I connected the G2 port on the SF302 to a Gig copper port on the Catalyst. I configured both ports as trunked ports and port e1 on the SF302 as an access port for the phone. VLAN 1 is the default VLAN and VLAN 10 for voice. However, the phone does not connect to the Call Manager. I have changed the configurations on the G2 trunked port and the ethernet port (trunked ports, general ports, tagged and untagged). I have also changed the configuration on the Ethernet port (general, access, trunk, set it on the default VLAN, in the voice VLAN, etc.) The SF302 connects to the Catalyst, and PCs connect OK.

For a customer of mine I've installed 8 WAP 200 access points with an SF302 switch. The Access point are powered with POE. All seems to function properly: the clients are simple Android device and the connection appears solid.. We've a good roaming between access points (not seamless of course but is ok) and no particalur problems, also because the network is used to drive very LOW data (no internet): the clients opens a tcp connection to the server and sends only a keep alive packets over this connection.. Then sometime the server send a very small amount of data (some byte) to activate the display of the device and show a question.. the clients reply with some other byte of data and so on.. During an event of 3/4 hour we can do this 12/14 times, so the network load is nearly 0....
Last night the system suddenly stopped working: ALL clients (300) lost connection from their access points at the same time! How this can happens? The only reason that I can imagine is a power loss on the switch...

I want to connect a Cisco small business switch (sf302-8) to a Cisco catalyst 2960S over a multi mode fiber. The transceiver I am using in the catalyst is a GLC-SX-MM. I presume in the SF302, I will have to use a MGBSX1. My question is "are these transceiver compatible with each other and if not, is there a transceiver that will suit both pieces of hardware?

I am trying to set up a Vlan on an SF-302-08 small business switch. I would like two Vlans both with internet access but the two cannot communicate with each other. I am not really sure how to go about setting this up as its all fairly new to me. I have successfully set up the Vlans and the ports on each VLAN cannot communicate with each other however the internet access will only work when plugged into either VLAN but wont work on both together

The past two days have been frustrating with my wifi. When I first got on it, I checked the internet access because I couldn't get onto the internet. The connections had "limited access". I restarted my router and modem, and it did nothing. I unplugged everything and plugged it back it and the wifi would show, but I couldn't get on it. I restarted the router and modem, and it worked. I got on Cisco Connect and the signal wouldn't show. I got off the computer and later, I couldn't get on the internet again. Later on, I could get on the internet again. I got on Cisco Connect, and it still says that there is no connection. I haven't a clue what's going on. My modem is CenturyLink, and obviously, my router is Cisco.

I have been having some gripes with the above problem for the past few days, connecting several PCs in my office into a network. To cut a long story short, it's a bunch of XP SP2 and SP3 machines with only some of them having these issues. The network consists of two switches and one router with integrated modem and wireless. Internet access is established over that router/ ADSL modem.I have drawn out all the cabling and made all the connections myself, I don't doubt network related hardware one bit. Basically, I had the problem on two PCs, I tested connectivity on that cable with a laptop which didn't have any problems connecting to the network. All the cables are brand new, "straight" connectedC

I manage a small office network IP's are generated via a rooter. I need to add a new pc to the network and here is where the problem starts.I have a cable from a HUB in that office which has a splitter 1 way goes to a PC the other is empty. At first i tried connecting the other PC from that splitter but i get the Limited or no Connectivity message on both PCs. If i connect only one of them to the splitter the connection works fine.Now i tried with a HUB, made a Crossover cable from the splitter to the HUB in the WAN port, same deal both PCs get Limited ot no Connectivity. THe strange thing is that if i connect only one via the HUB the same thing happens.I am really out of ideas, my only option left is to connect the PC from the main HUB which means allot of cable posing.
