i've a problem with my SF300-24 routing. That's my network configuration:
Port 1 to 12 assigned to VLAN 10
Port 13 to 23 assigned to VLAN 20
Port 24 has an ip 10.17.7.254 to connect with my deafult route, beacuse I've also a Linksys RV042 router, connected in turn with my ISP router, having an ip 10.17.7.1.
My SF300-24 switch has been working 100% as a backup switch for a client of mine. At my clients premises it was running 3 Vlan's and doing inter VLAN routing. When my client received their original switch back, I obviously brought my SF300-24 back to the workshop, reset it back to Factory defaults and tried to do a fresh installation on it. I can not get it to change from Layer 2 to Layer 3! I installed the latest firmware but still no go.
Everything works a 100% via the console, but when I go to the System Mode menu and try and edit it, it justs sits at layer 2 and will not chage to layer 3!
now we have 2 switches: SF300-24..on one SF300-24 we config it at layer 3 mode with VLAN configuration same as following [code] And we use port 26 on 2 switches SF300-24 is trunk mode then we connect both SF300-24 switches.But on SF300-24 layer 2 cann't inderstand VLAN from Sf300-24 layer 3..How to config VLAN on 2 switches SF300-24 Layer 3 and SF300-24 layer 2?

How to condig SF300-24 to vlan 2 vlan 3 can get IP address from DHCP server in VLan 4?
it says that the cisco sg300-28 managed switch default system mode is Layer 2. but i want to change it to layer 3.
i can't get inside the "Console Interface Main Menu" where the switching from L2 to L3 will be done.
I have done the ff:
1. Upgraded firmware to 1.1.2.0 (latest)
2. Reset the switch to factory defaults.
3. The guide stated that in order to perform telnet to the switch, you need to enable it. So I logged in first in to the web GUI and enable telnet service.
4. I can now start telnet on the switch but I can't see the "Switch main menu".
All I can see are these lines from telnet:
User Name:cisco
Password:******
switchd5928c#
I just want to know how to get into the console interface main menu where these lines should appear so that i can change the system mode:
• System Configuration Menu
• Port Status
• Port Configuration
• System Mode
• Help
• Logout
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 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.
I'm setting up an SNMP poller to retrieve the ARP table (ipNetToMediaPhysAddress) from my SF300 switches. I can retrieve the table from SF300-24P and SF300-48P switches running Firmware Version 1.0.0.27, but get garbage for the MAC address when retrieving that same table on the same model switches running Firmware Version 1.1.1.8. Is there an outstanding defect on this code level? How can I retrieve the table showing the IP address to MAC address mappings?
View 1 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.
We 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 configure 3750 stack switch as core and 2960 stack switches as access layer switches.I connected my laptop to one of my core stack in VLAN 10 and I am pinging to one of my server in VLAN 1. What will be the minimum latency at the time of inter VALN routing

We 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 new install with 3 SF300 switches, setup as vlan 2, the switch connected directly to the 2901 router has no problems, plug in a phone and it gets an IP, but if connected to either of the two swtiches behind the first switch, they do not get an IP. I am seeing the DHCP request hitting the router, and the router sending the IP to the phone, but it never gets the IP.

View 7 Replies View RelatedI'm playing with an SF300-24P switch and want to connect an IP Phone. I'm more familar with IOS syntax than the SF300 GUI.
How would I replicate the following in the SF300:
Switch(config)#int fa0/1
Switch(config-if)# switchport mode access
Switch(config-if)# switchport access vlan 15
Switch(Config-if)# switchport voice vlan 5
Not sure if setting the port to an ACCESS port on VLAN 15 (i.e. 15UP) and having the Voice VLAN set to 5 is correct.
Or should the port be set to General or Trunk with 15 as the untagged VLAN and 5 as the tagged voice VLAN (i.e. 15UP, 5T)?
My ISP is providing me with 1 public IP on a /30 network and 14 public IPs on a /28 network. In this example the 10.0.0.1 is the default gw provided by my ISP and 10.0.0.2 is my SF300-08. If I setup my router to route to 10.0.0.2 as the default gw through the interface between the switch and router, can I configure the static routes in the switch to route further to 10.0.0.1?
is it possible to have these 2 networks on different VLANs and configure inter-VLAN routing? I don't want the switch accessible from the 10.0.0.2 IP.

View 1 Replies View RelatedWe have a mitel 3300 PBX that is our DHCP server. It feeds an old Foundry Networks switch that nobody knows the password for anymore so I can't even look in it to get some clues. What I think I know is this.
vlan1 = PC's subnet 10.0.0.X 255.255.255.0
vlan2 = phones subnet 10.1.0.X 255.255.255.0
Phones plug into the switch, PC's plug into the phone.
I am assuming this to be the case becase all the PC's get those numbers and when booting up a phone it comes up and says "vlan2 pri 5" during the DHCP discovery.
Like I said the Mitel 3300 is the DHCP server and our internet access is from the firewall's trusted port.
I have put the switch in L3 mode via the console. No matter what I try, the PC will always get IP addresses in vlan2's subnet. Even if I plug the PC directly into the switch.
I have factory reset this baby and all I have done at this point is put it back in L3 and changed the default ip address so I can get to the web GUI.
