Cisco Switching/Routing :: SG300 Upgrade / Backup Page Not Loading?
Feb 28, 2012
Just purchased a SG300-52 and am trying to upgrade the firmware to 1.1.2 but cannot get the Upgrade/Backup Firmware Language page to load in the web browser interface. I have tried IE 8 and 9, Firefox 3.16 and 10.02, and Chrome from Windows 7 and XP Pro systems also tried FF and Chrome from Ubuntu system. The page just never loads - doesn't show anything.The same is true of the Download/Backup/Configuration/Log page. The other links under Administration > File Management seem to work fine.

When my wife gets chemo, we spend the day at the hospital, and I login to their WiFi as a guest. When I do, I make a connection with no problem, but after the initial page comes up, additional pages load very, very slowly regardless of what browser I use (Chrome, Firefox, or IE). I don't have that problem on any other network. Moreover, other users on that same hospital network can login as guests without encountering that problem. So, the problem is not browser-related, and it occurs only when a single laptop connects to a specific network. I'm using a Dell XPS 16, running Windows 7 Pro with Windows Firewall.

I receive the following error message:The connection was reset The connection to the server was reset while the page was loading The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.I am unable to connect to Facebook on my home computer, but can visit any other site with no problems. I can access Facebook from my work computer. I am using Firefox on both. I only use wifi as I only have a laptop and my router is in my office. I can access Facebook on my phone with my wifi enabled. I have not tried a direct wired connection (will try that next and let you know what happens) as I don't use my office, because it's currently full of junk.
Clearing the cache and cookies
Reinstalling Firefox
Updating Firefox
Changed Firefox proxy settings to "no proxy"
Resetting my wireless router
Checking the Hosts file for facebook entries (there are none)
And still no access. The only way I have been able to access Facebook is by turning the firewall off on my wireless router (Belkin Wireless G). I don't want to have to turn the firewall off just to go on facebook. I am the only person in the house who uses a computer and the internet. So settings have not been changed, because I am the only person with access to change them (password protected wireless network as well).

I'm performing a migration from an ASA5520 running version 8.04 to an ASA5525-X running 8.6.
The issue I had was that whilst all of the SSL VPN portal configuration was migrated the initial portal page does does not load. I thought that this could be to do with ASDM and WebVPN both being enabled on the outside interface and so I tried changing the port used for ASDM and disabled the ASDM altogether on the outside - but still to no avail.
Could this have something to do with the fact that you can no longer just point your browser at the outside interface of the firewall to get to the ADSM? Does some configuration need to change for the ASA to accept connections on the outside interface?
The basic WebVPN access as it stands right now is:
webvpn
enable outside
anyconnect image disk0:/anyconnect-win-2.5.2014-k9.pkg 1

I just turned on 2 Wirelless LAN Controllers 5508 and I am getting this message on both of them:
Loading primary image (Image not found)
** Unable to read "linux.pri.img" from ide 0:2 **
Loading backup image (Image not found)
** Unable to read "linux.bak.img" from ide 0:2 **
And it is taking me to the BootMenu. I selected option 4 to Clear Configuration and the controller seems to restart the system but I still get the same error. I checked the LEDs status and Sys is Amber and Alarm is OFF which according to the documentation is a System Crash.

I have a website account with fatcow. I created the website with Dreamweaver software and uploaded it to fatcow via port 21.My internet connection was via xplornet and I had no access problems. I upgraded to xplornet's new g4 system and now I can no longer access my account online or upload to my website.We have two computers. The first is a desktop system that has the dreamweaver software. The second is a laptop which connects wirelessly. We share the signal through a dlink router. The modem is a viasat Surfbeam 2 residential satellite modem.1. When I attempt to login to the fatcow control panel, the tab shows successfully authenticated and then re-directs me back to the login page. This happens on both the laptop and the desktop.
I have tried bypassing the router and the problem still exists.I took the laptop to the computer center and I can login to the account no problem.I used a free proxy server page on the internet and can login from my home system on my desktop no problem.I have completely turned off virus scan and firewalls. It doesn't work. I have tried IE7, Chrome, Firefox and they all have the same problem. The laptop runs IE8 and has the same problem.I can ping the page successfully. I can traceroute the page successfully. I can't nslooup any site at all. I get the domain not existant message.My ip and dns settings are the automatically find option.I have renewed ips and dumped the dns cache.Using alternate dns addresses doesn't rectify the problem. When I attempt to upload via dreamweaver, I connect but within seconds I get a Dreamweaver message that says "Connection to remote host has been lost. Click refresh to continue" and the log reads "FTP Error. Dreamweaver could not connect to server." I haven't taken my desktop anywhere to try to see if it works on a different network. I'm in a remote location (hence the satellite internet)and it is an hours drive to the nearest private internet connection and a 2 hour drive to the nearest public connection.

I recently set up a small photography business and am trying to get a Cisco 877 and Cisco SG300-10 switch to talk to each other.
What I want is for the Cisco 877 to handle the internet and the SG300-10 to handle the local network,
I have set up 2 vlans in trunk mode on the switch and want vlan2 to manage local traffic and vlan3 to handle the internet.
I have got the 877 connecting to the internet what I dont have, traffic going to vlan2 on the switch from the 877
Look at the running configs for the switch and the router and tell me how to get the vlan on the router to pass traffic to the switch. In a nutshell I am inserting the internet into the switch but am not sure how to progress. I have the c870-advipservicesk9 image file on the router.

My company uses Cisco 891's in replacement of the 1811 where we would have DBU used via an external modem and a triggered time of 3 minutes after a primary connection failure was identified. In testing the 891 in a Layer 2 failure environment, it is within milliseconds that the v.92 port is engaging after the layer 2 failure. Has anyone been able to get it to attempt at a more than millisecond rate?

I am trying to configure Cisco SG300-52 switch for the first time and stuck without CLI configuration option. The configuration can be done using GUI, however, configuring using CLI would be more comfortable (as I am used to work with CLI of other Cisco switches)..
I was able to lo gin to switch using SSH, but the CLI appears in MENU format and was not able to find any way to go to CLI mode.
As per some blogs, in SG300 switches CLI mode can be accessed using Ctrl + Z in Menu, which did not work either in my case.
Switch is running with latest firmware version Sx300 Firmware Version 1.2.7.76.

I have three Cisco SG300-28 switches. I setup a test lab environment with a core (server) switch in Layer 3 mode and the rest are (clients) in Layer 2 mode. As I understand, these switches doesn't support VTP, only GVRP. And GVRP works the same with VTP. Whenever you create VLANs on the core or main switch, other switches will learn from the core switch and no VLAN creation for the client switches will be made. (Hope I got it right. I guess GVRP is more complicated than VTP). I want to use GVRP to create VLANs on the main switch so that I won't be doing it all over on the other switches. The following is my (so far) configuration through CLI only:I haven't use the web GUI. My SW version is 1.1.2.0.
1. I already enabled the GVRP globally.
2. I configured GE 12 & GE 24 as TRUNK ports for the core switch that connects both switches, I also configured GE 12 ports for both the client switches. All other ports are in ACCESS mode. (I am connected to GE 2 port)
3. I enabled GVRP on the TRUNK ports only for all switches.
4. I allowed all vlans on the TRUNK ports. (#switchport trunk allowed vlan add all)
5. All TRUNK ports registration mode is NORMAL and dynamic vlan creation is enabled on all trunk and access ports.
6. I created 3 VLANs without configuring its IP Addresses:
-vlan 2 = MGT
-vlan 3 = IT
-vlan 4 = MKTG
I don't know if I missed something on the configuration or the connection.
1. Is it necessary to enable all switches to layer 3 mode? Or depends on the network setup? Does this affect the GVRP?
2. Does switching ports to TRUNK mode means they are already 802.1q ports by default? Because I can't configure TRUNK ports to 802.1q (#switchport encapsulation dot1q) config like other switches. [code]

try to configure QoS on a Cisco Small Business SG300 Switch. I followed the instruction on [URL] and configured one Port for tagging my Traffic from a Aastra IP Phone. Tagging works fine (i verified with wireshark).The problem is, that all traffic to a PC connected directly to the Aastra IP Phone is blocked. Is there a possibility to tag any other traffic to the port as a default?

I just purchased an SG300-10 (negular, non-POE) and planning on using it with no special configuratinos initially. Longer term, will be using VLAN and QOS for VOIP.What I would like to know is if ports 9 & 10 can be used as standard copper cat5e ports, or are they only useful for special purposes? When I hookup my router/firewall to port 1 it all appears to work. If I hook it up to 9 or 10, the port lights do not come on and it doesn't work. I read that ports 9 & 10 don't have POE on the POE switch, but I assumed that all 10 ports would function with cat5e?

We are using the SG300 series switches, and have come across an issue where we need to block ARP broadcasts based on IP.
we have multiple computers, each with only one ethernet adapter, each adapter has two IPs configured, 10.10.10.x and 192.168.0.100.All machines have the same 192.168.0.100 address (Used for applications/hardware running locally to that machine and this IP cannot be changed).
When the machines are connected to the network, ARP is advertising BOTH the 10.10.10.x address and the 192.168.0.100 address.
As all machines have the same 192 address we receive IP conflict notifications on each machine.
How can the ARP broadcasts for the 192 address range be blocked?

I'm looking to configure the QOS for VOIP on my network.I have a switch SG300 and several no Cisco VOIP phone. What are the parameters to be taken to implement the QOS?
What is the procedure for installing the QOS? I need to create a VLAN for the data and one for VOIP?I read in the quick start guide that there is auto-QOS for VOIP?This can be done from the GUI? what are the options to put?

I have an SG300, configured with several VLANs. I'm replacing a E3000 with the RV180, I've got it in the environment, but I can't seem to get to the internet from hosts on the SG300.
I have Port 4 on the RV180 connected to Port 20 on the SG300...Port 20 is in the native VLAN (VLAN1) and VLAN1 is configured as a trunk. I'm relatively new to networking so I'm not sure where to start troubleshooting. I have the default route on the switch and I have the static routes for the VLANs on the router, should I be using tagging someplace?

I have a new redundant network with two cores C1 and C2 and five access switches A1 to A5. They are all Cisco SG300 switches. I have noticed there are too many STP messages emanating from one host which has a MAC address which cannot be traced on the network. In the redundant network, I made C1 the root bridge by giving it a priority of 4096 and C2 has been given a priority of 8192 so that it is the secondary root bridge in the network. I have left all other STP settings to default on the rest of the switches in the network.
The problem is that one host is advertising a RST root bridge all the time. Now it has a mac address which is different from the mac address of the root bridge itself and i cannot trace this mac address on the network. Look at the snapshot of Wireshark output in the attach.The source MAC address which is the host advertising all the time is 1c:df:0f:34:db and the root bridge is 1c:df:0f:bb:34:c4.
Why would the root bridge be resetted all the time?I've also noticed that one port in a LAG configuration on one of the access switches is flapping up and down all the time.I tried to troubleshoot this problem. It is not the cable. It would be something else. What could cause this flapping of the port?Could it be related to STP?
On the other Core switch C2 I can see a LAG status switching between forwarding and blocking all the time. What could make the LAG status to flap from forwarding to blocking and back all the time like this?

it says that the cisco sg300-28 managed switch default system mode is Layer 2. but i want to change it to layer 3.
i can't get inside the "Console Interface Main Menu" where the switching from L2 to L3 will be done.
I have done the ff:
1. Upgraded firmware to 1.1.2.0 (latest)
2. Reset the switch to factory defaults.
3. The guide stated that in order to perform telnet to the switch, you need to enable it. So I logged in first in to the web GUI and enable telnet service.
4. I can now start telnet on the switch but I can't see the "Switch main menu".
All I can see are these lines from telnet:
User Name:cisco
Password:******
switchd5928c#
I just want to know how to get into the console interface main menu where these lines should appear so that i can change the system mode:
• System Configuration Menu
• Port Status
• Port Configuration
• System Mode
• Help
• Logout

I'm looking for feedback and constructive criticism on our network redesign project for our company.We are currently on a 192.168.1.x/24 and running out of addresses. We are looking to move to the following design and implement VLANs as well for segregation and security. We are probably going to use a few SG300s for switches. [code]

Can a Cisco SG300-10P switch power a Cisco SG200-08 switch over POE? Or an SG200-08P power an SG200-08 via POE? I have an area where I'd like to put a small switch, but would like to avoid having to have electrical power run to it. Or will the SG300 and SG200 POE switches only power endpoint devices such as cameras and IP phones?

A client of ours has installed an SG300-24P switch and would like to setup a LAG between the SG300 and the 3560 switch we manage for them. They would like the LAG to also pass the voice and two data VLANs currently in use; 5, 10, and 100 respectively. I configured the two ports as an Etherchannel with trunking on the logical port, but no luck. I reconfigured as follows:
interface GigabitEthernet0/1
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode active
end
[code]....
I see no output when I do show lacp nei. At this point the client is looking to use for the configurations to use as he does not know how to setup the SG300 and it is a switch I have never dealt with. I have found some configurations that I believe would allow a single VLAN across, but nothing I believe will allow the LAG to pass all the VLAN's.

I am having trouble with my Cisco SG300 switch big time. I have two servers with IP addresses 10.17.0.11 and 10.17.0.29 sitting on the same switch which is a Cisco SG300. I initiate a file transfer from 10.17.0.11 to 10.17.0.29. I could see lots of Dup Acks and retransmissions which means something is wrong in the connection. Further, I could see the session initiation a bit bizarre. I could see two SYN packets sent from 10.17.0.11 to 10.17.0.29 and also two SYN ACK packets returned by 10.17.0.29. The switch forms part of a network but since both the servers are sitting on the same switch I suppose the rest of the network doesn't come into play when one server talks to the other.
See also the number of Dup Acks and retransmissions. The two switch ports connecting the servers have speed and duplex set to auto negotiate, flow control is enabled. What could cause this sort of problem?Could it be any setting on the switch or the servers' NICs?Or could it be a bad switch that causes this?
