Cisco Switches :: SG 300 10 Multicast With Multiple Switches In LAN

Jul 21, 2012

My internet router acts as an IGMP Proxy for the LAN and distributes IPTV there. The router is connected to one of my three SG 300 10 Cisco switches (connected to one another via uplink port). Now I want all switches to send multicast traffic to only the recipients of such traffic (PCs with VLC and Network Media Players) connected to either one of them. How do I have to configure the switches to do so and not flood the LAN with multicast traffic, is it enough to enable IGMP Snooping on each switch?

Cisco Switches :: SG300 Switches Can Be Used With Microsoft NLB In Multicast Mode

Dec 18, 2011

does the SG300 switches can be used with Microsoft NLB in Multicast mode?I know on traditional Catalyst switches you can statically "map" IP's to mac's and then to multiple ports but this doesn't seem to work correctly on the SG switches - it gives an error about the mac not being not Unicast?

Cisco Switches :: SG30028P - Implementing QOS For Over Multiple Switches For Two Vlans

Jul 17, 2012

I was looking for configuring QOS for two VLANS i have created. these will be for voice traffic vlan 22 and video traffic vlan23. i also have three other vlans for pc's, wireless devices and our cnc machines. we have 5 switches that are all SG30028P's with a single switch doing the intervlan routing (operating at layer 3). all of the switches are trunked back to the main switch and ive been through the guide written on how to do this on a single switch which i dont think is layer 3.

Cisco Switches :: Multiple VLANS And SG300-28P Switches Setup?

Aug 20, 2012

I'm going to have several SG300-28P switches to setup.  I'll need to create multiple vlans for data, voice, and wireless traffic.  I have the following questions in setting up this configuration:
VLAN 1 Management
VLAN 100 Data
VLAN 200 Wireless
VLAN 300 Voice 
1) For managing the switches via IP, will LAN1 be the default management network?  Should I create a seperate VLAN for managing the switches?
2) For uplinking the switches together, I plan to trunk a port to connect the switches together.  What's the configuration on the trunk port to forward all vlans from one switch to another?
3) On some ports, I want to configure a trunk for two vlans (Data and Voice) where the phone has a pass through for PC.  The phone supports tagging for the PC and the VoIP traffic.  For example on port 10, would VLAN 100 and 300 be set to tagged?

Cisco Switches :: SG300-52 Multiple Lags Between Switches?

Jan 19, 2012

I'm having alot of trouble trying to connect more that one LAG between two SG300-52 switches.Basically i have configured both switches with the same vlans. For 2 of the vlans i would like to connect them together between the two switches using LAG. Switch1 has Vlan 5 (ports 1-12) & Vlan 10 (Ports 25-36) with LAG configured on ports 1-2 and ports 25-26. I have setup the second switch identical to the first. But when i connect the LAG's there is no connectivty. If i disconnect one LAG the other starts working.Can you only have i interconnect LAG between switches?

Cisco Switches :: SG300- Use Multicast TV VLAN?

May 10, 2013

I want to use Multicast TV VLAN with my SG300-10 to join Multicast Groups in different Data VLAN's. It's working fine, but the problem is that it isn't possible to add all the Multicast Groups to the Multicast VLAN because each TV channel use other groups. For me it's only to handle if I can use wildcards to add a specific range of multicast traffic to the Multicast TV VLAN. Is that possible with that Switch?

Cisco Switches :: SG 300-10 Multicast Routing On VLans 10 / 20 And 30

Apr 9, 2013

I am IT teacher at a middle school in Nuremberg, Germany. We have in our school 5 VLANs, 4 Switchtes, 1 L3 switch and 1 router.
2 months ago the old L3 switch (Catalyst 3550-12T) is broken. In the short term I've borrowed a Catalyst 3750G-24, so that the network continues to function. Now a SG 300-10 switch was purchased. This should be configured the same as the 3550-12T or 3750-24G.The network looks like this (there are much more PCS than in this image):
VLAN Interface
The DHCP server in VLAN 30 is also a FOG server. The Fog server images all PCs in school. PCs in VLAN 10, 20 and 30 boot from PXE. The MS Server in VLAN 10 has been configured by the DHCP options 66 and 67.
The Catalyst 3750G-24 routes the multicast, but the SG 300-10 I do not have the option of using the commands ip multicast-routing distributedip pim sparse-dense-modeto work and must configure igmp. I'm having problems with the igmp-configuration on the SG 300-10. Therefore, I have uploaded the configuration of the 3750G-24 and the configuration of the SG 300-10 (without ACL).

Cisco Switches :: Manual Multicast ARP Entry For SG300

Jan 22, 2012

We're replacing our older catalyst switches with new SG300 family switches and have a Microsoft NLB cluster for some services that run in multicast balancer mode.
We currently do L3 routing to the network with the cluster and have the following IOS configuration line in the specific switch to let users on other subnets to access the services.
arp 03bf.0a14.01e2 ARPA
How do we replicate this using the SG300 series in L3 mode? Whenever I try to add a manual ARP entry I get an error message that says that the MAC address is not a valid unicast address?

Cisco WAN :: C6509E Multicast Configuration For Only Layer 3 Switches

Jun 13, 2011

If there is C6509E as core switches and C3750 Switches running layer 3 at the User dept uplink to the C6509E Switches, what will be the multicast command that should be implemented at both end? CGMP or IGMP or do not need to implement this snooping as well?

Cisco Switches :: SG300-28P Multicast (IGMP) And Routing

Dec 11, 2012

A brief background on the setup: I recently switched out my switch.  It was a Cisco 3750 10/100 switch and I wanted to upgrade to Gig.  The cost of a Gig+POE 3750 is too much to bite so I opted for the SG300.  My router is a Cisco 891.  Here is the setup:
Cisco 891:
two SVI's: vlan1 and vlan 100
Vlan1 =


With the 891+3750, I was able to add "ip pim sparse-dense-mode" on all the SVI's and hosts could join any multicast group, irregardless of which vlan the host was a member of.
Now I've changed switches, and I dont get the same love.  I have the PIM statement on both SVI's on the 891, but Im unsure of what I need to configure on the SG300.  I have enabled "Bridge multicast filtering" + "IGMP snooping".  What can I do to get similar functionality using the SG300 + 891?  I assume this is my lack of understanding IGMP in general, but was able to get away with it using the PIM statements on the 891+3750 stack.

Cisco WAN :: Multicast On 4510 Core Switch And 3750x IDF Switches

Jul 15, 2012

At our site we have a 4510 core switch and 3750x switches in our IDFs. The 3750 switches are connected to the core via DOT1Q trunks in a server client setup. We are putting in an Informacast/Berbee server witch will send pages and text to the cisco phones. We also have 1 3750 switch connecting to the core via a layer 3 port channel. If we put the Informacast server on the phones vlan would I just need to enable ip pim sparse-dense mode on that vlan only and enable multicast routing, ip multicast routing?

Cisco Switching/Routing :: 3750G / Switches Flooding Multicast Streams But IGMP Enabled?

Nov 3, 2011

I have a 2x Cisco 3750G switches (Stacked) that are part of an IP Video Surveillance System .All network is set to 1 VLAN (VLAN 1 default).The Cisco SWs ( Core )  are configured with IGMP Querier + Snooping .Connected to the Cisco SWs are 4 Fiber Rings(Loops)  for redundancy . RSTP and IGMP Snooping are enabled on all the network SWs .Network Architecture Figure :
When all Fiber Rings (Loops ) are connected , the Cisco and Ring SWs spanning-tree tables show the blocked and forwarding ports properly .I am able to connect all my IP Cams + Encoders to the Ring SWs and connect my Servers + WorkStations to the Cisco SWs to record and view the multicast ip streams .All streams from Rings 1 ,3 and 4 are getting normally to the Servers + WorkStations through multicast ( IGMP Snooping are filled correctly on the Cisco and non-Cisco SWs ) . All multicast streams are joined normally except for Ring 2 .The Multicast streams passing through Ring 2 will operate normally for around 2 hours then after that the Fiber SWs begin to flood their multicast traffic causing the cams on the same switch to drop off the network .

I checked the Configuration of all the SWs on Ring 2 but all are are the same .

What is weird is that I have to set all the streams to unicast to stop the flooding just on Ring 2 (All other rings are not affected ) then after some time if I enabled a video multicast stream on one of the SWs of the Ring it will be streamed properly to the Servers + WorkStations ( All IGMP tables along the way will be filled properly ) then again after 2 hours or so , the flooding will start again suddenly and all IGMP  table entries for the SW on Ring2 will be empty . No problem occurs on the other Rings which have more multicast streams .

Cisco Switches :: Configure Multiple VLANs On SG 200-18?

Jun 22, 2011

I am having problems accomplishing these tasks with my new SG 200-18.
I have a LinkSys WRT54G2 connected to port 1. I would like ports 2-8 to be in one VLAN with access to the Internet and to be able to share their printers, hard drives, etc. with other computers on ports 2-8. I would like each of ports 9-16 to be on a separate VLAN with access only to the Internet and no other ports on the switch. I would like to be able to manage the switch from any of the ports 2-8.
After I create the VLAN 1009 (see screenshot below), port 9 can browse the Internet and cannot see the other ports on the switch which is correct. However, ports 2-8 can no longer access the switch at in order to manage the switch.

Routers / Switches :: Setup Multiple Public IP's?

Apr 7, 2011

At my company, we lease 3 static public IP addresses from 1 ISP. We want to have 3 separate networks that each use one of the IP addresses. Network 1 is the computer network, network 2 is the VOIP network, and network 3 is the security camera network. I am trying to determine the best way to do this. I have come up with 2 solutions in my head, but I'm not sure if they will work or not. I would like to get some input. Solution 1:Solution 1 looks something like this. Fiber box -> Router-> 3 switches. There would be one WAN input on the router, that would have a static route to 3 different LAN ports. For example, address would be assigned to LAN port 1, would be assigned to LAN port 2, and would be assigned to LAN port 3 (by assigned, I mean have a static route to it). Is there some type of router that is capable of doing this? Solution 2:Solution 2 looks something like this. Fiber box -> Switch -> 3 Routers. The ethernet cable would run from the Fiber Box to a switch, and then 3 routers would be plugged into the switch. Each router would have the Static information configured in them. Would both of these methods work? If so, which would be the best way to go?

Cisco Switches :: Linksys SRW248G4 And Multiple Membership In VLANs?

Jun 26, 2012

I can't figure out how to configure a port membership with multiple VLANs. My setup:

- VLAN10
- VLAN20
- port settings tab: port24 in general mode
- ports to VLANs tab: untagged everywhere, when I set port 24 membership to VLAN10 I can't set port 24 membership in VLAN20 because when I do that port 24 membership in VLAN10 dissapears and vice versa
- but I can set port 24 membership to both VLANs in VLANs to port tab, but I think it doesn't work because:
- when I connect hosts to ports 23 (port 23 is a member of VLAN10 only) and 24 (member of VLAN10 and VLAN20)
there are not any connectivity between them
- but connectivity is working when I set the same PVID for both ports 23 and 24 in port setting tab, I can't set multiple PVID in here.

So, is it possible to configure port membership for multiple VLANs on this linksys. [URL]

Cisco Switches :: SG-200 To 887 Setup Trunking Between These 2 Devices For Multiple VLANs

With previous routers, you could set the router up in the configuration 'router-on-a-stick' and VLANs worked like a charm but the 887 no longer support sub-interfaces.So how can you get trunking working between the 2 devices?
Is there a VTP configuration menu for the SG-200 which we can setup in order for it to talk 'VTP' with the 887 router??
