SG300-28 SFP

Hi All,
I am trying to use SFP module from one transceiver to the cisco switch . I have a general sfp device which the lighs turn on when plugged in from port 28 to 27 which are sharfed sfp but do not work if port 28 is connected to another fiber transceiver.
Any ideas, what the issue can be ?
I suppose I don't need to buy a cisco sfp as the current one which is from COMM 1 seems to work if plugging port 27 and 28 directly (loop)
Thanks for all inputs

Is there an SG300 or SG500 that has all ports as SFP ports?

Hi Alan, actually yes, there is. Much to my surprise I was shipped one this week. I have a SG300-10SFP. However, I do not believe these are on the market yet since I cannot find any documentation for them.

Which sfp module add in Sg300-10 for connecting with 4503 switch over fiber?

Hello guys...
i need help in network design...
i have 2 cisco 4503 core switches with 48 port sfp that will use to connect at branches SG300-10 with 2 fiber that is single mode...
which module should use in Sg300-10 that will compatable with 4503 fiber module?
Please tell me if I will use the GLC-LH-SMD for WS-C4500 with fiber optic card WS-X4448-GB-SFP what type of SFP do we have to use for the small business switch SG300-10?
We could go for MGBLX1?
if i am ok please reply if not please provide the correct one solution for my design...!

Cisco SG300 - IGMP and multiple switches

Hi all,
I have read through various Cisco documents and tried various configurations and i have been unsuccessful
Here is the network layout
Cisco SG300-10 in Layer 3 mode, managing all VLANS created and inter-vlan traffic is working fine
Ports 1-4 are in LAG 1 with LACP enabled, Ports 5-8 are in LAG 2 again with LACP enabled, port 9 is connected to the ASA 5505 (Trunk port, all VLANS) and port 10, again a trunk port I use for management
LAG 1 and 2 are connected to Cisco SG300-52 switches
again traffic between the switches is working ok, what we would like to do is the following
on VLAN 7, we have multiple devices streaming using UDP multicast, what we would like to do is allow PC's on VLAN 5 to be able to pick up these streams as and when they need to, the devices broadcast on their own unique UDP ranges
Could someone please explain to me what I need to configure on the Layer 3 switch and the other two Layer 2 switches in order for this to work?
If i put a port into VLAN 7 and can view the stream without a problem, also if there is any fine tuning to be done once this is working
Thanks
Andy

Jason,
The only advantage you would get from using SFPs (fiber tranceivers) in the GBIC slots would be if you needed to make a run of over 100m between the switches. Unless you have a very large property with switches at either end you are just as well to use the copper ports in the setup you described. There is also nothing wrong with chaining the SG100s together if necessary to free up a port on the RV320. The only other thing to consider is if you are using VLANs. Each unmanaged SG100 will only pass a single VLAN so if you need segregated distribution coming from the RV320 you would need to put each SG100 on its own port. Or, you could run a trunk from a port on the RV320 to your SG200 and then split off your untagged VLANs from there. Hope this answers your question and have a nice day.

SG300-10mp Fibre Link aggregation

Hi,
I have 2 SG300-10mp switches which i am trying to create a link redundancy for over the two fibre ports.
On the web interface when i go into the LAG settings ports g9 and g10 which are the fibre ones don't show up.
How do i create the link aggregation between them? Or perhaps i'm doing the wrong thing... All i require is the two switches to function as normal, however should one fibre port become faulty or the cable to break, the over port just takes over straight away with no latency, or atleast very minimal.
Please help!

Hello Ashley,
I think I see where the confusion is here.
When you are looking at the LAG settings page, the 8 things you see listed represent the 8 possible LAGs that the switch can handle, the page actually looks exactly the same even with a 24 port switch. You are seeing the LAGs themselves, not your individual switchports.
If you go to LAG management, you should be able to select one of those 8 LAGs and click the edit button. The window that pops up should allow you to add both fiber ports to the LAG. I don't have one of these in front of me right now, but since the SFP slots on the 300's are combo ports they will probably be numbered as whatever the ethernet port combo'ed to the SFP slot is.
Simply add the ports you would like to the LAG, and check LACP if you are using it on the other switch (you cannot change this setting later, you would have to delete the LAG first).
This way you have the redundancy you are looking over with the added benefit of having more throughput available between those two switches, since the traffic will be load-balanced across the LAG.
A LAG will also failover much faster than two redundant links, since it won't have to go through the Spanning Tree process everytime a link state changes.
Like I said I don't have one of these in front of me right now, so if I messed something up let me know and I will try it in the lab tomorrow.
Let me know if you need any more information,

Cisco SG300-28 / SGE2000 / Catalyst 2960

Hello everyone,
I'm looking for switch to accompany Cisco ASA 5520 in data center, with 20+ GE ports and no need for PoE.
I would like to understand the difference between Cisco SG300-28, Cisco SGE2000 and Cisco Catalyst 2960, 2960-C and 2960-S Series (except specific number of ports). As far as I can see the Cisco SGE2000 has 4x SFP and is stackable unlike the SG300 with 2x miniGBIC/SFP, but not much else. Cisco Catalyst 2960 series offers some additional features like USB storage, but I can't imagine I will need that.
Any suggestions?
Thank you
Dan

Cisco SG300 with QLOGIC Sanbox 5800 Interoperability

Hi,
Is cisco smb switch compatible with Qlogic Sanbox?
We are presently implementing new Cisco SG-300 switches over an existing Qlogic Sanbox 5800 Fiber Network.
None of of new SG300 are able to initialise the Fiber ports at both ends (cisco to Sanbox).
However, Cisco to Cisco and Qlogic to Qlogic works seamlessly.
Prposed topology is here-in
Please advised.
Regards,
Leerish

Hi Leerish, I can't find the Qlogic SFP anywhere searching for 31980-00 B.
I found an optic support Matrix
http://www.qlogic.com/Resources/Documents/LineCards/Optics_Support_Matrix.pdf
Another way to approach this may be. MGBSX1 is the equivalant of the Cisco Catalyst SFPS GLC-SX-MM. If Qlogic has a matrix for interoperability, you may want to find which of their optics match the GLC-SX-MM and it should work with the MGBSX1.

MGBLX1 & Cisco SG300-28

I am trying to connect the 2 Cisco SG300-28 switch using the MGBLX1 module with a single mode fiber cable. When I inserted & removed the module it detected (see attached screenshot) but when I see the optical module it is not detected (see attached screenshot), the shared port of mini-gbic is not blinking. Is there are any compatibility issues with switch, module or single mode fiber? What is the minimum distance of single mode fiber optic cable? Do I need to configure the switch to enable the mini-gbic?

I tried your suggestion but there is no light in the shared port. I will try a patch cable to test the module. How do I know if the module is defective?

SFP Module - Need Clarification

I am currently trying to connect two Cisco Small Business switches via the mini-GBIC ports/SFP module/singlemode fiber.
I have an SG300-52 and SG30028. I ordered two MGBBX1s because I (misunderstood?) their purpose. I had read this chart:
http://www.cisco.com/en/US/products/hw/modules/ps4999/products_qanda_item09186a0080abed87.shtml
It lists the TX/RX of the MGBBX1 as 1310/1490 which I thought meant that the module can both transmit and receive. When I got the actual MGBBX1 SFPs they have only "1310nm" printed on them and the Quick Start Guide says they are upstream only! It also states to use a GLC-BX-D as the downstream module which I can't even confirm is compatible with the small business series.
I have never set up an optical network before. I have a singlemode fiber cable strung between two buildings already and have paid a few thousand dollars to get to this point only to find the MGBBX1 may not be the right SFP for this.
Can someone please direct me to the correct SFPs for this application?
Thanks.

Glad to know I'm not the only one confused by that.
After reviewing the MGBLX1 it is clear that this is the route I need to go. The specific listing of a "DUPLEX LC CONNECTOR" gives me confidence.
Thank you for the help!

4500x losing connectivity to SG300 switches issue

I have a new Catalyst 4500X-16 SFP+ Switch with ten GLC-SX-MMD SFP modules connected to ten Cisco SG300-10 switches with MGBSX1 SFP modules. The 4500X is all default config except all I did was setup SSH so I can manage remotely. I have GB connectivity between small SG300-10 switches and 4500X switch without any problems at all, until the SG300 reboots. If power goes out or SG300 is restarted for any reason, it does not communicate with the 4500X switch any longer. If I restart the 4500X, then connectivity is restored. I don't see any port security setup or no ports are down...everything appears up, but I can't communicate until I restart the 4500X switch.
I'm not sure where to begin troubleshooting this one. I am putting battery units on each SG300-10 switch, but that is just a temporary fix and I'd like to get to the core of the problem.
4500X is running IOS-XE Version 3.05.00.E
Thanks in advance for any help you can provide.
Below is info on the 4500 switch...

Below is info on one of the SG300-10 switches.

I updated my question with more information in case that helps. Below is spanning summary on the 4500.

SG500X-48-K9-G5 and SG200-18 compatible SFP

Hello,
I am interesting if GLC-SX-MM sfp modules are compatible with following switches: SG500X-48-K9-G5 and SG200-18.
Do you have any information about it ?

Hi,
It doesn't appear that the GLC-SX-MM is compatible with the SG500. I quoted the manual below so you can see the compatible SFPs for the two switches.
Best,
David

SGE2000 - SG300 - MGBLH1 - Connectivity/DHCP/VLAN

Hi Experts,
Need your help, advise and support to fix the below issue in bringing our network
Just extended our intranet buildings with Fiber Optic Connectivity with the Following Components
Data Center Building
1. SG2000 - CISCO
2. 24 port LIU - MOLEX
3. GBIC SFP Transceiver - single mode SG300 MGBLH1 - CISCO
New Building with OFC Terminated
1. SG300 Switch SG300-28P (SRW2024P-K9) - CISCO
2. 24 port LIU - MOLEX
3. GBIC SFP Transceiver - single mode SG300 MGBLH1 - CISCO
Post the OFC Termination and Splicing, we are able to get the Link and connectivity through the SFP Ports.
But unable to get the Ethernet Link up and running.
SG2000 is configured to be L3 Mode Switch with couple of VLAN configurations and working perfectly well.
Have configured one of the custom VLAN in the new building and made the DHCP Relay to be passed through, but it is not passing the DHCP traffic.
But peculiarly, when we connect both the ends with SG300, it works like a charm.
Hence, i went back to basics and checked the SFP compatibility, and alas, the MBGLH1 is compatible with SG2000
Please advise, what additional should be made to extend the network with the above setup.

Hi.,
I am sorry for delayed reply.
This issue has been addressed and fixed. To update what the issue was.
1. When we connected the SFP Ports to the corresponding locations, link was up but it did get pass traffic through, as I was tailing my DHCP server logs.
2. My ex-colleague helped me to understand, though the SFP ports are separate on this Switch(SG300), the moment we connect a SFP port, one of the ethernet port which lits up has to be configured to our requirements.
3. I had allowed the corresponding Gig port g/11 to allow the specific vlan and enabled the dhcp relay option. It started receiving the traffic on the DHCP Server.
One more Issue was: Only Ports g/11 and g/23 were working out of the Four SFP ports.
While troubleshooting, sh interface commands showed the g/12 and g/24 as blank, and after 3 hours of continuous amateur troubleshooting,
When logged into the GUI mode of the switch and clicked on the port g/12 in the status page, it threw an error stating, that "This is a stacking port and cannot be configured".
Then I disabled the Stacking mode and had to reload the switch to make it work.
It was really an awesome learning and was very interesting to do such stuff.
I am sorry if something were very basic things which I should have done and missed it. Forgive me as I am a system administrator who has deep interests in working with networking.
Please help as I may be posting many other questions like this as I am volunteering my time and support to a non profit organization.
Way to go !!!
