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 :: 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.

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 300-10MP Multiple Vlans But Shared Up-link

Aug 30, 2011

I have 8 apartments that have a single internet connection coming into the building, I then have a PoE Access Point in each of the 8x apartments.
What I would like to be able to do is to have each apartment within its own vlan, but to be able to use the internet via one of the non-PoE ports (port 9 say) but do not want residents in different flats to be able to see each others devices on the same network.
I have a Cisco SG 300-10MP which has 8x PoE ports and 2x Ethernet ports, one of which my Internet connection is plugged into (using WiMax).

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

Mar 28, 2012

We have a Cisco 887 router and a Cisco SG-200 switch.We'd like to setup trunking between these 2 devices for multiple VLANs on the switch to be made available on the router.
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??

Cisco Switches :: Multiple VLANs And Relaying DHCP On Two Stacked SGE2000-G5

Nov 17, 2011

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.

Cisco Switching/Routing :: 2960 - Private Vlans Across Multiple Switches

Nov 11, 2012

I am aware that private-vlans are not supported on edge switches like 2960 series - so my question is would it be possibel to ceate private vlans on say just the core switch which would be a 3570 or 4506 that supports private vlans and then just trunk these to the edge like normal vlans?
what I need to achive is to have edge port not able to communicate to each other even across switches - which cannot be done using 'protected' port so need the private vlan feature

Cisco Switches :: SG300-10 / Setup Multiple Routed VLANs Going Back To FiOS Actiontec Router

Aug 13, 2011

I just received a new Cisco SG300-10 and am configuring it in Layer 3 mode.  I am trying to setup multiple routed VLANs going back to a FiOS Actiontec router.  My configuration is as follows.
Fios Router:
Assigning DHCP through 100.
 SG300-10 has VLan 1 ip used for Mgmt.
VLAN2 is
VLAN3 is
I have a static route set on the fios router for both subnets setup as follows.
Destination Gateway Netmask Metric 1
Destination Gateway Netmask Metric 1
I have a laptop connected to Gi8 on the Cisco (Vlan 3) and statically assigned, with a gateway of  DNS set to the fios router ( 
Everything pretty much works EXCEPT, I cannot get out to the internet from either vlan.  Traffic routes between vlans/and the default subnet on the fios without issue.
When I ping out, DNS resolves, but will not go past the fios router.  Am I missing a setting somewhere?

Cisco Switches :: SGE2010 Switches / VLANs And A Blocked Port In Spanning-tree?

Aug 20, 2012

I have 2 switch groups.
2 SGE2010's with VLAN's defined as 10,20 and 30
Vlan 10 is the management VLAN, and it uplinks to our border router.Vlan 20 is the workstation VLAN, and all workstations point to the switch as their default GW? Vlan 30 is the ip phone VLAN, and all phones use this as their gateway.
I would like to put a LAG between said switches, we have some servers on the ip phone switch that need to be accessed by the workstation clients, and the single 100mb link through the router is probably not going to be enough.As I understand it, because the switches have different networks on them, a simple lag will not work. I did create a lag, and assign ip addresses to each side, however in that mode, it doesn't appear I can block vlan 10 from transiting the LAG, and with out that block I will end up with a logical loop, and spanning-tree will block one of the uplinks, or the LAG itself.

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 :: Implementing VoIP With SG300-28P

Oct 12, 2012

I want to implement VoIP on my client network, currently the data network is using SG300-28P small business switches for user access. According to my design the IP Phones (Cisco 9971 and 7942G IP Phones) are to connect to the small business access switches while the user PCs connects to the IP Phones.
My concern is I really don't understand how the small busness switches will advertise the voice VLAN to the IP Phones. I understand that the switches are suppouse to use LLDP/CDP for this but it seems the model I have can only do LLDP. The IP Phones and the PCs connected to them will be recieving IP addresses from an uplink L3 managed switch.
how LLDP works (particularly regarding this scenario)? Does it matter if the small business switch is in L2 or L3 mode for the VoIP implementation?

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 :: 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 :: 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).

1810-24G Setting Up VLANs On Procurve Switches

Oct 31, 2011

I have:

-Procurve 1810-24G
-Procurve 2520-8-PoE

Router (with Internet Connection) is plugged into port 24 of the 1810.My asterisk server is plugged into Port 1 of the 1810.The 2520 is plugged into Port 2 of the 1810, and all of the VoIP phones are plugged into the 2520.Rest of the office computers are plugged into the remaining ports on the 1810.

After setting up the subnet and assigning an ip to the 1810, everything else just worked out of the box. I would imagine that I should segment and prioritize the network so that the VOIP traffic is isolated and is higher priority from everything else.

I tried playing around a bit, but the phones lost connectivity, so I just defaulted everything back for now.

What would the suggestions be for setting up the VLANS properly to do this?I would also need one of the office PC's (say the one plugged into port 13 of the 1810) to be able to access the asterisk server.Also, would it be more optimal to have the asterisk server on the PoE switch or the main switch?

Cisco Switches :: VLANS Between SGE2010s And SLM2024 Via Fiber

Oct 19, 2011

I have  successfully set up a VLAN on my primary switch which is an SGE2010. I  have 3 other switches is other buildings connected in series. The next  in line is another SGE2010 and then a SLM2024 and an SGE2010. Each are  connected with Fiber and I'm not sure how to set up the switches so that  the router controlling VLAN 2 will push IP addresses to the clients on  that VLAN and allow internet access. We're using it as a guest VLAN for  our customers to have internet access. I have those GBIC ports set up as  trunks right now except for the SLM2024...I'm not quite sure how to set  that up. The VLAN is set up on each switch exactly the same though.

Cisco Switches :: AP514N And SGE2010 Configuration For Vlans

Dec 10, 2012

Id like to set up our AP to push our different vlans depending on which ESSID you connect to.
A few things I am unclear on. The switch port on the SGE needs to be in trunk mode I assume.
Do I marry the Management Vlan ID on the AP to the PVID on the SGE port ? Or is the PVID the untagged vlan ID ?  
I set the switches port to trunk mode, it's PVID to 10 and set the management vlan ID on the AP to 10 and I get TTL Exceeded in Route when I try to ping.
