Cisco Switches :: Connection To SGE2000 Managed Switch Web Interface Lost
Apr 19, 2012
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?

configure a secondary ip address (over the same address range) in a vlan interface on the SGE2000?For example, I want Interface Vlan 10 on mw switch has 172.16.10.1/24 and 172.16.10.2/24. Is that possible? If I try I get an error message with a duplicate IP address error. On Catalyst switches it can be done, but on Small Business?

We've been trying to monitor the used bandwidth of our SGE2000 and SGE2010 switches with Nagios.We've been experimenting with the various OIDs and we've found the OIDs linked to the different switchports.
Though when we use SNMPWalk (to find the OIDs connected to the port) the names of the ports are all the same.
[code]....
Is there a way to change the names of these interface to unique names?We've already given unique names in the description field through the switch's GUI, but it doesn't make any difference for Nagios.

I am running the SGE2000 as my l3 core switch with multiple inter-vlans.
have a customer requirement that needs to restrict eg. GUEST-VLAN10 to all other VLANS in the network. Only allowing access to the internet.
It seems on the switch i am able to bind ACL to per port interface. if this is possible on the SGE2000

DHCP Relay on a SGE2000 switch.I have configured two VLANs on the switch, VLAN2 (192.168.10.x/24) and VLAN3 (192.168.9.x/24). I have the switch in Layer 3 mode. I have configured the DHCP relay server of 192.168.10.4 and the DHCP Interfaces as VLAN3. All of the IP Static Routes were generated by the switch.
If I put a client computer on a port that is Untagged VLAN 3 and try to get a DHCP address from the server on an Untagged VLAN 2 port I never get a response back.I have done some packet captures and here is what I have found:
I see the DHCP broadcast on the client computerI see the DHCP Request on the DHCP server coming from the IP assiged to the switch on VLAN 3 (192.168.9.254)I see the DHCP server respond with a DHCP OfferThe DHCP offer never gets to the client computer I can't seem to get a DHCP address to any system not on the same VLAN as the DHCP server. Option 82 is disable and I did try enabling it, which made no difference.

I currently am using the SGE2000 switches for our datacentre and they have run great. We are looking at replacing them as part of our normal equipment refresh and have questions about what is the best switch for us. We are looking at upgrading to at least 48 port switches which isn't a huge issue.The main purposes of the switches will be for iSCSI traffic between Starwind SANs and Vsphere 5.1 hosts. We had some latency issues with one of the SGE2000s but otherwise they've been great.
We also will use these switches to handle our feeds from our ISP and our normal interserver communications. We have had DDoS attacks in the past of 40k packets per second and 600mbps and the SGE2000 never even flinched. We don't need it for any layer3 routing (which we use virtualized PFsense for). Looking at the Miercom report the SG200 series looks like it would be fine for us but I'm just worried around the part which mentions it becoame unresponsive in a DoS attack and also whther it may be slower for iSCSI. Both series seem to support flow control and jumbo frames.

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?

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 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 Campus LAN setup which is layed out using Cisco SRW2024 and SGE2000 SB switches. On the LAN we are running various services. These are CCTV, VOIP(SIP), Public Address(multicasting) and Internet hotspots to various locations. I have attached a layout of the setup. A unique VLAN is setup for each of these services.The problem we have is that the PA audio is breaking up at intervals making the output distorted this is also happening for the SIP phones within the facility. Using the user guide we have tried to setup QoS on the system but we seem not to improve the services.

I'm having trouble getting a stack of three sge2000 switches to connect together and NOT reboot.Two of the switches are older Linksys sge2000s and they stack well together, but as soon as i connect the new Cisco sge2000, it will make them both reboot sequentially, even though it detects that it needs to be #3 in the stack.SW 1 port 24 is connected to SW 2 port 12 and they function correctly (both of the linksys switches). The documentation states they should be connected in a ring topology so I first tried completing the loop with SW3 (the newer cisco sge2000). When that had the aforementioned troubles I just connected SW2 port 24 to SW3 port 12. Still forcing the switches to reboot.I SUSPECT it may be a firmware/software issue, but I wanted to check if they'ed even work together.

I have recently purchased a a Cisco SGE2000 switch and when connected to it via console cable, I was introduced to "Switch main menu" which was kind of a GUI interface. I found a way of accessing what is called a lightweight CLI (lcli).After having a few searches on google it turns out that this switch doesn't have a proper CLI. Is this possible at all? I thought that all managed switches have CLI?

I have a wireless router that was named and all the wireless equipment (laptop, ipod, phones) was connecting easily with no problems. Everything is saying "unable to connect". I have no clue what she did but she said her laptop asked her for the 8 number code from the router and she entered it.

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´ve got a strange problem with the connectivity within a ring topology.There are five switches from the SGE2000 series and one SG200-50.The SG200-50 is the root bridge and RSTP is configured.From the root bridge switch (Switch 5) I can ping Switch 0.But I cannot ping Switch 0 from PC0.
On the other hand I am able to ping all other Switches (1-5) from PC0.In addition to that I can establish a RDP connection from PC0 to Server0.This tells me that there is no general problem with the connection from PC0 to the Switch0.
Right now when I want to configure Switch0 the only way is to connect to Server0 first.But we have to move Server0 and this is why I want to manage Switch0 from PC0 like any other Switch on that network.

I have a Linksys SGE2000 Switch and I've been trying to get Vlan's to work.How I'm trying to setup is like this
Port 1 - Vlan22 - Plugged into trusted port in firewall
Port 3 - Vlan25 - Plugged into DMZ in firewall
Port 15 - is plugged into a VMWare host. The network is setup as production is Vlan 22, DMZ is Vlan 25.
Port 16 - Internal server so is Vlan 22
Both Vlans have a different IP subnet.I think I have port 3 configured ok as it's only one Vlan. I'm trying to get Port 15 configured properly and it won't work.Servers on VMWare hosts are Windows Server O/S.

I just want the switch to be quiet so that I can perform some network testing with only the connected hosts showing up in my traffic analysis program. But every 30 seconds or so the switch sends out an LLDP packet. This switch is only used in the lab for running tests so I know I don't need the LLDP feature running.
This article explains how to disable LLDP globally on a Catalyst switch, but I can't find any option to disable LLDP in the SGE2000's configuration menus.

I need a ≥ 8 port layer 3 managed switch. What would be the cheapest solution for this?I've been looking at some stuff like Cisco 4908G, but that only supports 1000base-X. I need something that supports the standard 1000base-T. I've also looked at a Cisco WS-C3508G-XL-EN, but correct me if I'm wrong, this is only layer 2?

I have a brand new SG500-28P sitting on my desk.
The swtich is configured and going to operate in L3 mode. All ports are still assigned to the default VLAN ID 1. I have created several new VLAN's. Once I configure and aplly an IP Interface to a certain VLAN the swtich becomes inaccessable right away. I am pretty sure I am not pulling my own VLAN under my connection. Every port is inaccessable. I have to pull the power plug and restart the swtich with its saved configuration. Even when I add another IP interface to the default VLAN 1, same issue. I have tried lot's of things, but can't get it to work properly. I have just upgraded to the latest firmware.
I have configured dozens of SG300 swtiches which is very easy. This one does not work with me.

We have been set the task of securing a small managed office system which is currently set up with a standard switch allowing each of the offices (containing different companies) to see each other, and in some cases, access each others documents across the network.
Obviously this is a far from adequate set up and our aim is to isolate each office using VLAN's but share a common internet connection provided by the managed offices. We have two Cisco SGE2000-G5 layer 3 switches but we are new to Cisco equipment and VLAN's so we are not quite sure on how to implement this. DHCP would need to be provided by a Router, there is no Server. We are open to suggestions on the Router as we have yet to purchase one.
