We have a potential new customer who is wanting to deploy a guest WLAN. I am happy doing this via a VLAN on the WAP4410N series AP’s. I would then create the relevant VLAN’s on the switch. Can each VLAN be assigned an IP address and allowing me to be able to add a static route on the router pointing the traffic for the Guest VLAN back to the switch?

As far as I can tell it will not let me enter a UDP port range for the RTP traffic... And I cant imagine creating rules for each port would be very effective either. So, how can I define an ACL to cover the RTP traffic so I can classify it?

Originally I was happy just set them all up in a stacked ring configuration. However I've become aware that my back bone fibre links are contantly pushed to their max.
So I've decided that I should change this configuration and unstack the switches and make them all stand-alone units. and I'll configure 2 cable LAG links between all my switches Theorically I should now get 2GIGs between each switch and to complete the ring in my network for redundancy I'll turn on Spanning tree.
However I've tested the speed and I just can not seem to get a LAG connection with 2 x 1gig cables to push more data than a single link 1gig link cable would.
My test enviroment(not using fibre optic cables just cat5e copper cabling):
4 x pc's(all gigabit network cards)
2 x sge2000p switches
PC1 ---(1G eth)--- /---(1G eth)--- PC2
[SGE2000P]===(LAG1 2x1G cables)===[SGE2000P]
PC3 ---(1G eth)---/ ---(1G eth)--- PC4
If I send files from PC1 & PC3 simultaneously to PC2 & PC4 They don't transfer faster than if I I just use a single 1GIG Link cable
looking at the LAG configuration it shows both cables are connected & the LAG looks like it's working. But it really doesn't seem to be running at the expected 2GIG?
The LAG fail over seems to work fine if I remove either of the 2 cables from the LAG the link continues to work. (sometimes it will drop a ping when removing or readding a LAG cable)
I'm planning to separate voice and data traffic with two vlans. I have a COR switch catalyst 3750, a UC560 for VOIP with SIP trunk and SGE2000P as access switches. The thing is i had configured VLAN1 (data vlan) and VLAN8 (voice vlan), i've created the vlan 8 in the database on 3750 and let pass those vlans through a TRUNK port. In the SGE2000P configuration i've created the VLAN8 and the the ports as trunk for letting pass the two vlans for the PC and the IP phone. This works but some phones aren't registering, and for example i've unplugged a register phone and plug and doesn't registering anymore.

Im trying to recover the password from my stacked switchs(doing procedure on master switch),im following a guide i have read in this forum("SRW248G4 V1.1 unable to reset password"), at console terminal have chosen "password Recovery" it prompts the "current password will be ignored" and then i hit "Escape" the switch start loading de configuration, at this point i attempt to login from telnet or http but the login fails.

I'm using a stack of four SGE2000P switches for a PoE video camera system. I've got the cameras in a VLAN and everything's working fine.
I'm wondering, though, is there a way to find out what data rate the stack interfaces are working at (since it's going over cable infrastructure we put in ourselves), and also what percentage of that bandwidth is being used? I don't see anyway to get to those interfaces from the main page, and I wasn't able to find a way to do any sort of percentage thing even on a regular interface.
I am having problem setting up SGE2000P switches to work with my default data VLAN and additional voice VLAN. I am configuring it to pick IP address for phones from voice VLAN which is working fine but when I connect a PC on phone port it is also picking up an IP from Voice VLAN while default VLAN is data with different scope of IP.
I pack these switches and purchase ESW 500 series. I have ESW 500 at another client and they are working fine out of the box but this guy is giving me hard time.
Currently, we have a plain network and we are planning to 'upgrade' it a little. We want to implement VLANs to separate wireless clients, workstations + servers and infrastructure devices form each other.As of now, we have no VLANs, and no managed Switches. We only have an RV016 that handles two ISPs and a 3rd party connection service to the office branches ( I belive they're using Frame Relay, but as far as we know, we are not concerned since we cannot touch their devices)
The reason behind the title, pointing towards the famous SGE2000P, is that my workplace is located in Argentina... and we don't have as many choices as some of you guys have ! In fact, I was unsuccessful trying to get a Cisco partner to contact me. We would like to replace the RV016 with a cisco 1941 (and a HWIC switch card).
So, back to business..! Assuming we will be using the SGE2000P switches, I was thinking about setting VLANs using 802.1Q through seven of these switches, along with a 1941 Cisco router. I'm expecting the 1941 to handle load balancing between both ISPs and the 3rd party link. Now, as for Inter VLAN routing, I would like to have gigabit traffic between VLANs.
Is it possible to use one SGE as Layer 3 mode to hande inter VLAN traffic (gigabit speeds) while using the 1941 as a end point device to reach internet (using PAT) ?Would you suggest me to use the 1941 for Inter VLAN routing, despite the 10/100 limitation(*) and use all SGE's in L2 mode? We need two ISPs, a third link for the FR connection, and finally the LAN interface. As far as I know, I'm limited to the gigabit builtin interfaces for WAN purposes, am I right?
I'm working with a customer who has an SGE2000P and a Catalyst 2960 to setup and configure a single mode fiber link. The SGE2000P has an MFELX1 fiber GBIC and the 2960 has a GLC-LH-SMD GBIC. When I have the customer plug in his fiber, there is a power light that comes on on the MFELX1 GBIC. Neither GBICs/switches show that a link or activity is occurring, but the presence of that light makes me think that they are connecting somehow. Are these two switches/GBICs compatible?

View 2 Replies View RelatedWe have several of the SG300 Serices switches. We use them to route VLAN traffic to Remote Offices, Internet Connections, and WiFi Access Points.In one remote office we have a SG300-10 setup to route the HQ Network and the remote Office Subnet. The SG300 is Connected to HQ via Fiber and has multiple Tagged VLANs on it. If I do speed tests over the Fiber Link on the Incoming Tagged Netwotk I get Decent performance, 80Mbs. If I switch to a networtk that is not priginating from HQ, and have the SG300-10 route packet, I get dismal performance. 15-20Mbs.
I Fireded up a New SG300-28P FW v1.2.7.76. Added a the HQ VLAN 101 and new VLAN 1025 . Mapped some Tagged and untagged ports for each. Switch was connected to HQ Network as untagged VLAN 101. I put a laptop on an Untagged VLAN 101 port. Ran some tests, cam back with 750-850Mbs. Great. Put the same laptop on a Tagged 101 Port, Configured the NIC for Tagged VLAN 101, Same test, same Speeds, 750-850Mbs.I then Configured laptop for Tagged VLAN 1025. Connected to tagged VLAN 1025 port. Ran speed tests, resuts were 15-20Mbs!
I then Configured laptop for Untagged VLAN 1025. Connected to unagged VLAN 1025 port. Ran speed tests, resuts were 15-20Mbs!It was only the Laptop and the Connection to the HQ net on the SG300-28P. Why is the performance of this unit soooooo poor when it needs to route?Other Switches have FW v1.0.0.27 or FW v1.1.2.0. They have Similar speed issues. All Configured for Layer 3.
I have a situation where I have ethernet traffic from two separate networks/ip subnets (Subnet A and Subnet B) on a single ethernet connection. I have the need to separate the traffic into two separate networks and two isolated broadcast domains. I thought this could easily be accomplished with a Cisco 300 Layer 3 switch, but I can't get it to work correctly. I have the switch set to IP routing mode. I have three VLANs configured. VLAN 1 sees the combined Layer 2 & 3 ethernet traffic for both subnet A and subnet B. VLAN 10 has an IP address assigned from subnet A and is the gateway for devices within that subnet. VLAN 20 has an IP address assigned from subnet B and is the gateway for devices within that subnet. IP proxy arp is on by default and should be active.Devices in VLAN 10 can ping devices in VLAN 20 and devices in VLAN 20 can ping devices in VLAN 10. This appears to be working only because the switch is the default gateway for those components.
No devices or servers in VLAN 1 can ping VLAN 10 or VLAN 20 components, and VLAN 10 and VLAN 20 components can not ping VLAN 1. I analyzed the ARP traffic on VLAN 1 and the switch is not responding with its own MAC address for requests for IPs for active devices connected to VLAN 10 or VLAN 20. The Cisco documentation says that the device should be responding and acting as a router.I can not physically connect everthing on VLAN 1 directly to the switch, I can not make the switch the default gaeway for all devices on VLAN 1, and I can not create static routes directly to the VLAN 1 switch IP address for all devices that are part of VLAN 1, so I am stuck. I need the switch to let VLAN 1 components automatically know what is connected to VLAN 10 and VLAN 20.
I am willing to scrap this approach entirely if there is an easier way to do this. Put simply, I have a few devices in Subnet A that need to be isolated from Layer 2 & 3 traffic destined for a few devices in Subnet B, but I can't reconfigure my entire network to create these isolated broadcast domains.
I am trying to setup my 3550 layer 3 switch to do hand out dhcp addresses for different vlans. It is connected to my router address 192.168.1.1. I setup a new vlan 3 and the dhcp pool..

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?
Users (IPTV) -> C3750 (Access Switch) -> C6509E (Core Switch) -> C6509E (Server Farm Switch) -> IPTV Servers
Do we need to configure multicast at C3750 Switches (Access Level) at the User dept? Let's say the IPTV Mulitcast is 239.1.1.1. How can we build up this multicast configuration based on this scenario?
I have a project I am working on that will require routing over a MetroE circuit to connect a few sites together back to HQ. Although, I know this can be accomplished several ways, I have come up with a solution that I think will work, but would like you all's input as to whether this is adequate and if my thoughts on how to properly "organize" the network are right.
I have been working with the SG300 line in Layer 3 mode and have not had any issues in a test setup I have here in the office. Basically my thought is to have a single VLAN/subnet allocated for each physical site. That will handle the basic interoffice connectivity etc. I also have a need to prioritize voice/video traffic throughout the entire network. My plan was to create an additional VLAN/subnet to house the teleconferencing equipment. Thats pretty much the jist of the setup. My only question is how to properly prioritize the voice/video VLAN.
Do you have the ability to setup DHCP servers on this layer 3 switch? I know I can with my old 3550 switch. Want to upgrade and make sure this model supports setting up dhcp servers on it.

View 7 Replies View RelatedI've been conducting research on configuring 3 distribution switches in my network which are Cisco Catalyst 4507's to communicate with our core over layer 3. Our core switch which is already configured at Layer 3 for intervlan routing is a Cisco Catalyst 6509.
I've got the configuration portion complete and all devices are able to communicate my only question is about QoS. Do I have to configure QoS at the layer 3 interfaces for voice, if so how is that completed. We have several vlans and separate the vlans for each building by voice and data. We only configure ports on the access switches with voice vlans for QoS and we use the auto qos option on these interfaces.
How to set the management interface on a SG300 Switch in Layer 3 mode? I've some vlans configured on the switch with interfaces in each of them:
Vlan 100 (10.0.1.254 /24)
Vlan 200 (10.0.2.254 /24)
Vlan 300 (10.0.3.254 /24)
...
Vlan 900 (10.0.9.254 /24)
Now, the management interface is listening on all interfaces (IPs). But I would like to configure the switch to only listen on 10.0.9.254. What I need to configure or whether it is possible?
I have a SG300-28P switch. I just read in the Administration Guide that, when in Layer 3 mode, the switch doesn't support MAC-based VLAN or Dynamic VLAN Assignment.
So, in order to assign a client to a VLAN based on their MAC or based on the response of a RADIUS server, we have to disable layer 3 features. Without layer 3 switching, the switch is unable to act as a default gateway and forward packets between VLANs. As a result, the VLANs can't communicate in any way, or access the internet, unless a separate router is connected to every VLAN. Right? Doesn't this limitation significantly reduce the usefulness of the DVA feature?
I've been taught/under the impression that vlans and stp stay in the access layer to prevent bridging loops and broadcast storms from taking down the whole network. Well I was reading about backbonefast and how it "Enables fast convergence in the networkbackbone or core layer switches after a spanning-tree topology change occurs." Now I thought that from the distribution layer up we use a routing protocol.
View 9 Replies View RelatedWe are currently designing Layer 3 to the edge EIGRP solution for our customers. The network is a hybrid of collapsed core (Core to access) as well as a three layer design (Core/Distro/Access) for connectivity to the Data Centre, Internet, Wireless Blocks etc.The core of the network contains two 6509-E switches interconnected on a Layer 3 Port channel (no VSS). Access Layer switches (3750-X series running Stackwiseplus protocol) connect to the core switches over p2p routed links and Distribution layer switches (3750X stackwiseplus) provide connectivity to the Data centre, Internet, wireless blocks etc.
The access and distribution switch stacks(Cisco 3750-X) are set up with two or three member switches with uplinks multihomed to the primary and secondary core switch with each uplink included in EIGRP. In each of the stacks, one of the switches controls the operation of the stack, which will be the stack master.As the Cisco Stackwise architecture is not SSO-capable but NSF aware, all Layer 3 fuctions must be re-established during a master switch outage. To minimize control plane impact and improve Layer3 convergence, uplinks should be diverse and originate from the member switches instead of the Master switches in the respective stack. This is as per Cisco recommended design solution.The above solution can be setup if there are more than two switches in the stack. i.e. uplinks are configured on the backup member switch modules.
1.But what about stack with two switches..Which switch should be set up as the Master for a two member stack with uplinks to the core primary and secondary from each switch(Master and Backup)
2. For Layer 3 routing, does the routing takes precedene over switch failures? Say for eg. In a two member stack, the master switch with uplink to primary fails, does EIGRP provide a fast convergence to route traffic via backup secondary and does not wait for the control plane on the switch stack to converge? All the access to core links will be set up for ECMP.
I have a question if I Stack a Catalyst 3750 L3 with a Catalyst just L2, will we able to use all L3 capabilities?
