Cisco Switches :: SG200 / SA520 - Strange Error On Switch

Oct 17, 2011

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

Cisco Switches :: SA520 Lack Of HW Resources / ESW Series Switch

Jun 5, 2011

Updated formware of a partners ESW224  to the current GA code.I tried to add a ACL to a ESW switch.  The switch was connected to a SA520.
 
I setup a guest network on a AP541 and propogated that guest VAP VLAN  down through a ESW224 and down to a SA520.
 
On the SA520 I disabled IP routing between VLANs.  All worked OK.
Guest and corporate clients could get differeing IP addresses deopending on which VAP they connect to.
 
But the wireless  guests could still ping the management interface of the SA520.  This is a security violation for the partner.Tried to setup a ACL on a ESW224  to deny traffic from getting to the normal corporate vlan or 192.168.75.0.
 
But received a popup on the ESW when i tried to create a ACL.  It suggested there is a  lack HW resources.
 
I disabled ESW advanced QOS.Tried to add a ACL , but still have a error message saying lack of HW resources.Why do I get a message saying lack of HW resources ?

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.

Cisco Switches :: Can't Find The Switch / SG200-8 (SLM2008-TNA)

May 27, 2013

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?

Cisco Switches :: SG200-26 Switch Seems Unable To Reboot

Mar 9, 2013

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.

Cisco Switches :: SG200-26 Switch VLAN And Internet Access

May 9, 2012

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.

Cisco Switches :: Replaced WS-CE500-24LC Switch With SG200-50P

Jun 29, 2011

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.

Cisco Switches :: Can SG200-08 Switch Work With Dell PowerConnect 2716

Feb 23, 2012

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.

Cisco Switches :: SG200-08 And SG200-08P Fail To Hold Or Update Date / Time

May 24, 2011

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

Cisco Switches :: SG200-18 To C2960S Trunked - SG200 Cut Off The Net

Apr 29, 2012

how to connect our new SG200-18 to an existing Cisco network, in particular a C2960S.Here's what I've got:
 
<----- Rest of network ------- C2960S ----------- SG200 ----- (PC connected directly to the SG200)
 
On the C2960S-side here's what I've got on the corresponding interface:
 
interface GigabitEthernet1/0/1
switchport mode trunk
 
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.

Cisco Switches :: Very Slow Transfers Between SG200-18 And SG200-8?

Apr 16, 2013

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.

Cisco Switches :: Strange Network Standstill SG-300?

Dec 20, 2011

we have a production network that uses five SG300 switches that functions brilliantly most of the time. four of our switches run in layer 2 mode and the last switch runs in layer 3 as it is used to route our 7 vlans as well as routing traffic between our two gateways. the switches use the original firmware that shipped with the devices (v1 device) and will be upgraded within the next week.  the problem that we have is that the network seems to stop routing for all of the hosts after a given time. the only way to fix this issue usually is to reboot the main layer 3 switch. the main layer 3 uses a default route to one of the gateways and a return route has been applied in the gateway. the only thing i can think is that somewhere one of the devices routing tables become full and the network stops responding.

Cisco Switches :: SG200-18 Switches With LC Single Mode Fiber SFP's

Dec 2, 2012

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?

Cisco Switches :: Replacing Some Netgear Switches With SG200

May 16, 2012

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..

Cisco Switches :: ASA5505 - Does IOS Like CLI Exist In SG200 Switches

Aug 28, 2011

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.

Cisco Switches :: CLI Access To SG200 Switches?

Dec 27, 2012

Cisco Switches :: SG200 Vlans Across Two Switches

May 22, 2011

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.

Cisco Switches :: SG200-50P - Devices Not Get 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?

SG200 Switch Keeps Polling?

Oct 27, 2012

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.
