Dell 5324 - Managed Switches And Port Boot Time
Nov 29, 2012
I recently installed a Dell 5324 switch as my main switch and it's my first time using a managed switch at home. One thing I've seen as an issue in a corporate environment, and now here, is that managed switches tend to take a bit longer for a port to be active. Ex: a PC is turned off, I turn it on but if the PC boots up very fast the port may not be ready. All mounts fail. This is the issue I am facing with my HTPC. It runs Linux and has a SSD, and it has no UEFI bios to slow it down (which is good, I hate UEFI for that) so it's up and running within 5-10 seconds of pushing the power button. The network mappings fail because the port is not ready by the time it gets to the script that mounts everything.

We have recently purchased SG 300-52Port Cisco Switch to support our Network but they constantly having some bizarre issues or I assume bugs, i.e. we cannot Telnet nor SSH to the switch now, whereas we were able to SSH before, we have set them up for Remote Log Services to get some syslogs and reports but no report have been generated nor logs,
I have done some testing through Wireshark and there are absolutely no reports / logs.We have some real issues with this switch and it’s hard to believe that this is a Cisco Product,
SG 300-52 Port Gigabit Managed Switch
Firmware Version (Active Image ) : 1.1.1.8
Firmware Version (Non-active ) : 1.1.0.73
Boot Version : 1.0.0.4

I'm searching for a managed switch that allows me to not only mirror a port/ports, but also to still use the destination port for the mirrors as a link to the internet/the rest of the network. Aside from this, I still need the VLAN functionality of good switches, and ideally PoE provided, too.
I have seen the majority of the features of this in the NETGEAR GS108E (http:url...), but this doesn't provide PoE to the ports and also requires Windows to log into.Is this a feature of many switches? I can think of many snooping applications where it would be incredibly useful.

I bought an ESW 540 8-port switch, mainly for the POE capability over all 8 ports, so that we can power some SPA50X phones.The concepts of a "managed" switch are challenging for a newbie.Is there a way to make this device behave like a boring "unmanaged" switch ??We have plenty of bandwidth, and don't need to be troubled by QoS and virtual LAN's, or all the security stuff at this time.Making this device work like an unmanaged switch (aka plug-and-pray).

I have a sge 2000 24 port POE switch that won't boot, won't communicate on console or TCP/IP, and all of the port lights are lit up green. Holding down the reset button doesn't fix the issue and there aren't any lights illuminated on the left hand side of the switch.

such as the SLM2048T can be configured as an managed switch. Our schools have laptop carts and we want to put switches in the carts so that the laptops will be plugged into the network when not in use and software installs, updates, etc. can be pushed to the laptops while they're in the cart instead of waiting for them to be taken out, powered on and pushed over wireless. I can find a 10/100 48-port unmanaged switch, but I really want a gigabit unmanaged switch, but they don't seem to exist so I was wondering if a managed switch can be configured and used as an unmanaged switch. I don't want to have to assign a static IP address to the switch.

I have bought this switch to try :
We (our company) have a new glass fiber internet from a provider with 5 ip-addresses in an /29 range. I try the accomplice the following. On port 1 comes the output from the provider. On port 2 till 7 I want to separate the ip addresses so can distribute these addresses to our lan, to a wifi hotspot for external company visitors etc. So on port 2 a ip to the lan, on port 3 a ip to wifi router

I just purchased a new SF-300 managed switch for the purpose of using it on the DMZ, so we can mirror the internet port and monitor traffic for my company. I have set it up from the web interface to miror port 1 to port 2 and that's pretty much it. I decided to test it before putting it in production, by hooking it up to one of my core network switches, connecting a laptop to it and trying to get online. It doesn't even connect to my DHCP server to get an IP address. If I put the laptop back on the same subnet as the switch management IP, I can still connect to the switches web interface. Isn't the basic functionality of a switch to pass traffic?
I should also mention that I'm not a network engineer, so there might just be something I'm missing with regard to a default setting that needs to be switched off?

I need an 8 port switch to mange 6 web servers and while I haven't been able to decide whether or not I need a managed switch, I have recieved conflicting answers from sales reps with respect thier construction.In a 24/7 environment, is an SG100D-08 any different than a managed SG200D-08 switch in terms of the product components?Is the managed SG200D version any more reliable/dependable for 24/7 usage?

We have a standalone Cisco SGE 2000.
We lost connectivity to the web user interface - it no longer responds on the configured IP address.From the manual we see that by default the switch get its IP address via DHCP - but we find no record of any ip address assigned to this switch.Is there a IP address that this unit defaults to when DHCP is not available? Also - what is the best way to connect to the console using Windows 7?

I have installed an Aironet 1130AG and utilized a power injector for the power source. I have the settings configured correctly in IOS, but the AP takes about 7 minutes to come on (illuminate LED status lights) once the Ethernet cable is connected. Is this 7 minute power-on delay normal when using POE? I am used to the instanteous "on" that usually comes with Cisco products being connected directly to the AC adapter.

I just bought this switch off Ebay and I can't seem to find anything online on the physical connection of this switch. It's not like normal switches where it just uses a ethernet type cable that goes to serial, it requires a female to female cable which does not exist anywhere so I ended up buying a gender changer for a normal cable I had but can't seem to get the prompt to come up. I'm using 9600, 8 data bits, no parity, 1 stop bits and no flow control. Do some wires have to be crossed a special way or something or do I need to type anything special in the console to get the prompt? I can't find much online on this switch. At least not as far as serial connectivity goes.

When I came back home today I saw that my SG200-08 switch did not look fine.Basically, the system LED of the switch keeps blinking and end devices connected just don't have any network.I tried to reset the switch with the "reset" button (with a paper clip) the system LED was orange during just a second and then continue to blink.What is wrong with the switch?Is there a way to flash a new firmware and/or to delete the configuration file?

I have a SG200-50P. It had a problem with the PoE ports (didn't supply power to my Bosch POE security cameras) so I updated it to the latest firmware. Now it does recognize the cemeras and supplies power to them. However, there are a few problems:
1. The boot time is extremely long, maybe 15-20 minutes for it to become ready. I've tried to reset to factory default settings, push the reset button for 30+ seconds, and disconnect all the ports. The boot time was always very long.
2. Even thought it supplies power to the cameras, the PoE lights on the ports are not lit.
3. The log is filled with this error, posted every second.

I am in the process of upgrading our stack of 4 switches consist of WS-C3750G-48PS. Upon reading release notes found that there are two versions of release notes 1 day apart, the one 02 Sep 2012 saying that WS-C3750-48PS is not supported in this version. Then in release next day 03 Sep 2012 that note has been removed. Which one is correct. Is it supported with my model of switch or not.also unable to update boot path in the stack switches, "switch all" is not supported in the current IOS. Master switch has new boot path but unable to change in slaves.
