Cisco Switches :: SG200 Switch Not Forwarding Packet?
Jan 7, 2013
I have a problem with my SG200-08 Switch the switch not forwarding a special Packet. I try to run a simple Profinet installation for testing on the switch but it didn't work correct. A special packet (Profinet error message) was not forwarded.
I have tried it with different Profinet masters with Siemens Profinet master it works without of problems. With Rexroth master it dosn´t work. But it is the same packet only another Mac Address.
I have added two Wireshark logs, where I have mirrored the slave and the master port. With the Siemens master all packets are forwarding (every packet is double longed) with the Rexroth master the alarm packet was not forwarding (the alarmpacket is lost between the ports).
With a not managed Switch it is no problem too run both Installations correct. I have tried the Factory default Settings of the switch and too deactivate all services of the switch (like Spanning Tree, ..) but it was all the same, the Packet was not forwarded.
I recently bought a SG200-08 8-port gigabit switch. The switch firmware is the latest (1.0.0.16). Everything works fine, except that packet loss I have when flood-pinging on the LAN.
I have 3 machines connected to the switch, they have 1000 full duplex links, they all have Ubuntu Linux installed on them, no limiting on the switch (as far as I can tell), no limiting on the machines (nothing like htb, cbq), no QOS set up on the switch, the machines are fairly OK hardware-wise (dual-core, quad-core, six-core). And still, it doesn't matter which way I ping, I get a consistent packet loss of 5-7% when flood pinging:
I recently purchased an SG300-28P. I have 2 VLANS/subnets that are successfully routing between them.Machines on both sides can ping each other just fine, but none of the usual Windows/NetBIOS browsing is possible. I've recently learned that NetBIOS is not usually forwarded between subnets. How would I enable NetBIOS packet forwarding between my subnets?
Reading the manual, it seems like enabling UDP Relay might be the answer but I've been unable to get it to work (same with DHCP relay).
I had a SG200-8/SLM2008TNA switch that I was using on my lab network (192.168.9.x)One of my clients had an emergency so I moved the switch to their network (10.1.2.x)I can't see the switch at all! Cisco FindIt toolbar won't discover it (other switches on the client network are discovering OK)I changed my computer's IP to the range where the switch used to live...still can't find it I also don't see any new devices in DHCP with cisco-looking MAC addresses.Of course, the SG200-8 doesn't have its MAC address printed anywhere on it, and doesn't have a factory reset button.It's passing traffic OK but I was hoping to get it configured via web console and set for SNMP monitoring. how to discover/reset IP/factory reset this thing?
We have 2 of the SG200-26 switchs. When ever we loss power all the settings are reset to default. Even if we loss power for 1 min. This includes the IP, user, password, etc. How can I change this so the settings are saved?
Cisco SG200-26 (not PoE model). After a power failure, at restart the switch seems unable to reboot. The power led starts blinking in green, after some seconds the connected ports start blinking as well, but the the switch reboots automatically after few more seconds.I tried to disconnect lan cables, power cord, and reset to factory by pressing and holding down the proper button for 30s and more, but no success.In the small amount of time the switch's ports seem to be powered up, clients don't receive packets, don't ping each other or the switch manage address.
I start writing this post telling you that I'm not a qualified network admin, so I beg your pardon if I do not use appropriate terms in my question. Also my english in not so good since I'm Italian and my english in almost scholastic.
This is the "story" :
I bought two switches as described above and actually I have to create 2 VLANS as described below :
VLAN id 2 name "Service_A" ports 1-4 VLAN id 3 name "Service_B" ports 7-9
all other ports can stay in default VLAN1.
my network infrastructure have some other very simple swtiches connected and 1 soho router (static ip 192.168.1.1) with dhcp active and ip pool address released from 192.168.1.100 to 200.
the SG200-26 have static ip 192.168.1.254 and 192.168.1.253
MY NEEDS:
I need VLAN for privacy matter so all computer connected to ports in VLAN2 cannot see nor enumerate PCs and resources on other VLANs, but I also absolutely NEED that all computer in every ports (and every VLAN even default VLAN1) can access the internet.
I have just recently replaced a WS-CE500-24LC switch with a SG200-50P. I have plugged in a Cisco 1760 router with a fast ethernet into the switch. On the console of the router I now see these messages: [code]
As far as I am aware both ends of the link are set to autonegotiate the speed and duplex.
Last week and just yesterday, our switch SG200 50/50 logged an error like this:
%CDP-E-MALFORMED_TLV: CDP message from 88:43:e1:ab:66:f8 cached with illegal Appliance VLAN-ID TLV
At the time of the error, the SA520 router's LAN Port 1 where the SG200 Port 49 connected went down. (Light is OFF) So internet is down and other V LAN are disconnected. The MAC address on the log is the SA520 router. This happens 2x now and it needs for me to reboot both switch and router. and goes back again online.
SG200 50/50 Port Firmware 1.1.1.8 SA 520 Firmware (Primary/Sec):2.1.51/2.1.18
I have no previous Cisco switch experience. I just received a brand new SG200-08 switch. It replaces a small blue Trendnet 5 port switch. I configured the SG200-08 with a static IP address which is on the same subnet as all our wired devices, then I installed it and connected a computer and printer and another switch to it. The other switch is a Dell PowerConnect 2716. I suddenly have no network connectivity with the router any longer. When I plug the network cable that runs from the PowerConnect 2716 into the SG200-08, the link status light will not go on for that port. I am going to be replacing the Dell PowerConnect with a Cisco switch as well, the SG300-10.
SG200-08 and SG200-08P fail to hold or update Date/Time.(New installation for a UC320 setup.)I've got both an SG200-08 and SG200-08P that are failing to maintain date/time when set with "Use Local Settings". Every restart/powercycle causes them to reset to Dec 31 1969. Other settings save fine.I first tried to set time via SNTP Unicast using a variety of public time server addresses including the 3 hard coded to the SG200-08 firmware:
Sadly though it always just shows "Active Server Server Host Address: 0.0.0.0" and continues having 12/31/1969 as the date. Both after a config save and a reboot.I can ping the NTP servers just fine from the switches either by IP or by hostname.At this point I've decided that I must be missing something simple. At least I hope so... otherwise it's a firmware bug which means waiting for a fix.Other devices behind the same firewall/gateway (RVS4000) are updating NTP
I'd like to use an SG200 swicth to allocate bandwidth on a 100 Mbps fiber Internet uplink.I will have 5 routers (each supporting a separate network) connected to the SG200, and I'd like to give each network 20 Mbps. QOS configuration, best CIR and CBS settings for this.
On the SG200-side I've set the IP-address and default-gateway accordingly, however:From the SG200 I can't ping any other host on the same IP-subnet as the switchFrom the SG200 can't ping the default-gatewaycan't ping from any other host or the default-gateway *to* the switch But:On the SG200 I've got plenty of MAC-addresses under "Dynamic Address Table" - however only MAC-addresses that belong to the management-VLAN of the SG200 (i.e. VLAN9 in my case)The MAC-address table on the SG200 even includes the MAC-addresses of hosts on the same VLAN I tried to ping without success. For example: I tried a PING from a host having a MAC-address of 00:19:bb:31:91:30. This MAC shows up in the arp table of the SG200. To cross check I connected a dedicated PC to the SG200 and assign it an IP-address out of the management-LAN-range of the SG200 - in this case I can access the switch (i.e. PING, WEB etc.)So to summarize: Connectivity is OK when going from directly connected devices to the SG200. No connectivity from devices that are behind the C2960S towards the SG200 and vice versa. (The problem is definitely not with the C2960S-side since we've got plenty of them hooked together without problems.) I'm enclosing the screenshots of the corresponding definitions on the SG200.
I'm baffled by the poor performance that I'm seeing when passing traffic between my two Cisco SG switches.
The configuration is as basic as I can make it, no VLANs, QoS or bonding. Both have been updated to current firmware as part of the troubleshooting process.
When I transfer data within one of my switches I see 50/60Mb/s. When I pass the same traffic between both switches I see 0.6 Mbs/ or less.
I have tried to eliminate every possible factor including switching out the cables. No success.
We have a project in which we are using 34 Cisco SG200-18's each with a MGBLX1 (LC Single Mode Fiber) SFP mini-GBIC.All the fiber's come back to one building where we must "bridge" all 34 fiber connections. What hardware should be used to accomplish this? A L2 switch? For example, a 12 port SFP Switch with Fiber SFP's accepting the first 12 fiber connections, then other switch with SFP for the next 12 and so on, until there is a overall capacity of 36 and having patch cables between the 3 switches?
what cisco or non cisco hardware would work with these SF200-18's to accomplish this?
We are replacing some netgear switches with the Cisco SG200. The situation is relatively straightforward. We have a series of VLAN's coming in on a trunk from a service provider for our Metro Ethernet locations. These trunks then get cross-connect to various location for connectivity. The problem we have is there are two VLAN's that need to go to the same switch which provides access to our public IP block.
I set up the two VLAN's on the SG200 with the trunk port VLAN tagging on the service provider port. Then I set up a separate port for untagging the traffic with the PVID of the respective VLANS's as follows: [code] The public switch has no VLAN's configured (it is an SG200 too). If I connect GE2 to the public switch everything works fine. When I connect GE3 to the public switch, things die. I thought this might be caused by STP although STP should not be detecting issues like this across separate VLAN's. Disabled STP, no change.The same configuration with the Netgear worked without an issue. FYI, the VLAN's cannot be changed...they are defined by the service provider in this particular case. otherwise we'd just make them the same..
I need to purchase a few Gigabit PoE switches for a small business and I am thinking that SG200 or SG300 switches are perfect for this purpose.
Layer 3 functionality in SG300 switches is not great - HSRP or any other next-hop redundancy protocol is not supported, dynamic routing protocols are not supported, policy-based routing is not supported, etc. I may get one SG300 switch for inter-VLAN routing so that I do not have to send traffic to a Layer 3 device for this purpose, especially because my Layer 3 device (ASA5505) has only 10/100 Mbps interfaces. All other switches in the network don't have to be Layer 3 switches, and I am thinking of perhaps getting SG200 instead of SG300 swithces. However, because I am a long-time Cisco engineer, and know ins and outs of the IOS CLI, I would much rather administer the switches with CLI rather than GUI. So, do SG200 switches provide CLI (even if it is not officially supported) or is the only Small Business switch platform that supports CLI SG300? I do realize that the OS running on these switches is not IOS, but after having reviewed the CLI manual for SG300, I would say that 90+% of commands are identical to IOS CLI commands.
I just picked up a pair of 18-port SG200s, and I'm trying to figure out of there's some secret trick to getting CLI access to them? I've upgraded to the latest version of firmware (1.2.7.76) hoping that may work, but no luck.I can tell the guts to support a CLI are there, because writing the config out to a TFTP server shows identical an identical config style to the SG500 I have here.Is there some way to enable it?
I am trying to set up three vlans across two switches. The switches are Cisco SG200 and SG 300 series. There are 20 devices connected to the two switches including a router for Internet. Among these devices are five wireless access points all hardwired to the LAN. If I understand correctly the first thing I have to do is aggregate the two switches. I ran two cat5 cables to ports 1 and 2 of each switch. As I understand it all I need to do is to create SAG with the two ports on each switch. I think I need to use tagging but I don't really understand how to do this. Once I get the trunking set up correctly I want to create one vlan to which all devices will belong for Internet access. The other two would be for data and VoIP. Do I create vlans with the same name on both switches? When I assign the devices (by port) do I need to enable tagging? Which type of port setting should I use? I am assuming that by including the acess points in the vlans will mean that any wireless device connected to them will have acess to the Internet and the devices in the same vlan.
I have one server which run some application for wireless user. this server forward multicast packet to wireless user. server and wlc physically connect to cisco 3750 switch.i want the server forward the multicast packet to wireless users.server access vlan 4.wlc controller have 2 vlan: 90 and 110.and wireless user some of vlan 90 and some of vlan 110.i enable igmp snooping on wireless controller. and enable globally command but it is not working.which additional configuration i need on cisco switch.
I am trying to connect an SG200 to a customer's existing network. The customer does not want to receive any bpdu frames from the SG200. The customer's port has bpdu guard configured to err-disable their port upon receipt of a bpdu.
How do I completely disable spanning tree on the SG200 so that it does not send any bpdus?
My SG20-50P Switch Log appears as follows with Random ports going up and down. I am trying to find out if this links to another problem I'm having with a Client Server software locking up on the client end. The hardware, thin clients and desktops, are working and have checked all sleep and power settings. All items in working order, now I'm wondering about the switch
I saw the announcement stating that "200 and 300 Switches now supports Cisco Pre-standard POE" available here:[URL]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?
I just purchased a SG200-50P switch to replace a WS-CE500-24LC, that had a limited amount (4) of PoE ports. I was running Cisco 7940 IP Phone, Cisco AP1231 and AP1100 series access points via PoE off of this switch.
When I attempt to plug in these device types into the SG200-50P they do not power up. What is going on? Why do these devices (7940 IP Phone, 7960 IP Phone, AP1100 series access point, AP1231 series access point) not get PoE from the SG200-50P switch?
I have an SG200 switch and am trying to import a certificate signed by my own CA. I generate the CSR and sign it using Java's key tool with my own root cert. When I attempt to import the resulting cert, the switch blanks out the certificate text box and deletes all of my d name data (CN, etc) from the switch. What am I missing?
Just purchased a Cisco SG200-26 (non-PoE version).
It works great, but since hooking it up to my network, my Synology NAS won't hibernate.
So I went and checked if the switch was polling, and indeed it is. Every 1-2 seconds, the activity LED on all connected ports, flashes simoultaneously.
When the LED on the switch flashes, the network LED on my NAS also flash. So I'm prone to think the switch is polling the entire network every couple seconds.
I've tried disabling Spanning Tree, and other other options that could relate to the issue, but without any luck.
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 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?
I got a new switch and am trying to connect a UCS server to it. I can ping the switch just fine but when I try to use IE8 or firefox, I can't get to the web interface to configure it.
Here's my setup:
Cisco UCS C210 M2 IP = 192.168.1.100 Subnet = 255.555.255.0
I have an SG300-10 and an SG200-26. I also have an OpenWRT flashed router that can tag VLANs.My problem right now is that my default VLAN is 1, my router is doing DHCP in VLAN 1, and I want all my network equipment to be on VLAN 1, but my SG200, when LAGed to the SG300, will not get an IP.My SG300 is pulling an IP just fine from my router DHCP pool. When I connect the SG200 directly using either 1UP port settings or 1TP port settings, I get an IP just fine. When I LAG my connection (ports 1-3 on both) I get no DHCP information sent through the LAG to either the SG200, nor to any client devices that are set for DHCP.
what the intention behind adding SSH to the SG200 series switches was. Is it to allow SCP copies to and from the switch for configuration and firmware updates OR is it to allow CLI access to the switches.
I have tried to SSH to the switch using PuTTY from Windows and native SSH from Linux/Unix clients, but nothing happens.
Is there some other area of configuration to enable communcation via SSH?
