Cisco Switches :: LACP Between C4503 And SG300 With Media Converters
Nov 16, 2011
We recently purchased SG300-52s to be deployed as IDF switches of several buildings. We also implemented LACP between it and our core cisco 4503 switch. In the inserted image, the first setup where we used Cat 6 UTP cables, LACP connection worked flawlessly. However, when we tried deploying it using our fiber optic connection and media converters, the LACP won't go up.
I would like to know if you have experienced the same problem and what could be done to correct this situation. Initially, i am thinking that it has something to do with the media conversion from copper to fiber, vice versa. I am searching the web for similar problems but can't find one.
I need to know if LAG channel groups can be used to increase capacity of media converted links? (i.e. wireless links).For example.. aggregating two 1300 series wireless bridges via 2 switches.
I just installed a new 2960 to replace a 3550 this last weekend. All of the fiber media converters will not connect to the new switch. The converters are made by Black Box and Desa. If I plug them into the 3550 they link up immediately. If I plug them into the 2960 there is no link whatsoever. I've tried letting it auto-negotiate and tried turning off inline power on the 2960 with no luck.

However these ports are not in use and have nothing installed...............Firmware 1.1.2.0 (latest as of Nov 2011)
I work for a place that has its own TV broadcast system. From the central site we have contracted fiber connectivity to each of our 10 remote locations. To each location we currently have fiber for data (1Gbps) and fiber to transport our TV channels. Am am looking for a device that can take in our TV channels on coax and give me an rj45 ethernet connection so I can plug the unit into a data switch to use our data fiber for everything (if I need 10 units at the central site to do this, that is fine).taking the ethernet back to coax to distribute TV to all of the TVs in the building. This would eliminate me 10 point to point fiber links.
These are our first switches and seems like GUI is lot different than the online. Out intervlan routing is o not working. I am absolutely sure that I setup the switch in L3 mode since it allows me to create mutiple interfaces. I am hoping that this GUI issue is related to interVLAN routing.
Below is the blog I started for InterVlan issue [URL]
This is the link for online simulator and what I see in its IP tab. I know this switch is not SG300. [URL]
This is what I see on our switch.
Our switch version switchd64684#show version SW version 1.1.0.73 ( date 19-Jun-2011 time 18:10:49 ) Boot version 1.0.0.4 ( date 08-Apr-2010 time 16:37:57 ) HW version V01
I have SG300-28P that I am using as layer-3 switch. Recently I ran in to SG300-52 switch and even though loading same firmware doesn't give me option to do layer-3 switching. For SG-300 I see options in GUI to create vlan interfaces under IP information section, while SG300-52 has IP information option only under the management section.let me know if these are 2 different hardware types and L3 is not possible on SG300-52. If its possible to enable L3 switching on SG300-52?
I used LACP on port 49 and 50.After upgrade firmware from 1.0.0.19 to 1.1.2.0 my LAG1 stay down...all port member stay down, port link is up but LAG stay down...I testtu delete and reconfigure LAG1 but nothing work...
I am trying to setup up a LAG with LACP between the switch and a Sinology DS1511+. Every time I enable LACP on the LAG I cannot get the ports to become Active Members.
I'm replacing 2 3COM 4500 Swithes with the SG300-52 Cisco switch. We have 3 VLANs, 10, 20, 100. The switch is set for Layer 3 and I have setup DHCP relay. what settings i should set on the Cisco for the following setups:
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.
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?
Any snmpset commands to add, modify and delete vlan table entries on SG300-10 switches? I checked url... however this information is apparently only valid for catalysts. The latest firmware is installed and the provided MIB files are used.
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:
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?
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?
I have two SG300 serie switches and two Gigabit connection between them. How do I configured these two links to work toghether like a one 2 Gigabit channel?
I have a Cisco LMS 4.2.1 on a Windows 2008 Server R2 platform and I would like to backup the configuration of my WS-C4503-E version cat4500e-universalk9.SPA.03.03.01.SG.151-1.SG1I create the job in Configuration > Configuration Archive > Synchronization and after the execution of the job, I check th status in Admin > Job > Browser: I don't know why the archive doesn't exist. It's a newly install.
Currently i've a cisco ws-c4506-e edge swith loaded with cat4500e-ipbasek9-mz.122-53.SG4.bin image file. Can i use this image file on a ws-c4503-e as well?
I have a question, does the SG300-28 support VTP and STP?. I want to add it to my network's VTP domain so I don't have to manage vlans manually on the SG300-28 and also be able to configure STP to keep my network loop free.
I need to know how to configure each port in switch SG300-10 to vlans, i need to configure one port "trunk" with catalyst switch and assign 4 ports to different vlans. any solution?
In the CLI documentation for the SG 300 Series, it shows sh ip route rip as a command. I have installed the latest firmware and that command is no longer available. Does the SG300 series support RIP?
We purchased a SG300-52 last week to replace a 5yr old Dlink which has worked perfectly. 1 day after the SG300 went it it started crashing with this fatal error problem so I reverted the firmware back from 1.2.7.76 (latest) to 1.1.2.0 but I still get the problems. It crashes when I have it on my lan with users connected or if I just have the switch on my desk with just my laptop connected, so it cant be a load issue or a network topology issue. I already have a Cisco SGE2010 on my network without problems.
I have a question about ACL and binding. I have a SG300 28P and a couple of other linksys switches and Access points that are connected to it via trunks. The cisco SG300 28P is running in layer3 mode and i have created a couple of vlans and one of them is a guest vlan. Now to my question, i create an ACL and an ACE that vill funktion so that guest vlan only can connect to the internet and not the rest of the internal network. And then i must bound the ACL to an interface port or lag, what i can see it is not possible to bind it to an vlan? so if i have a port on some of the other switches that is member of the guest vlan, vill the ACL on the SG 300 stop guest vlan trafic to the internal network that is comming from some of the other switches?
I want to set up a vlan only for the wifi APs and wifi clients on my network. They can't access to any server, only internet acces. I already implement this configuration and its working, but now I want to allowed a couple of laptops to connect to servers in other vlan. what should I do? Should I do it using Mac address of laptops or IP?
Yesterday I upgraded my SG300-10P to firmware 1.2.7.76. I was curious about the new SYN Protection feature, but it seems to do nothing on my installation.
The switch is running in Layer 2 mode. I have ACLs in place and DoS prevention is not enabled. I also tried clearing ACLs and enabling DoS prevention. As I understood the Admin Guide enabling DoS in the Security Suite Settings is not necessary for using the SYN Protection.
In my firewall I see about 300 pps with SYN flags only arriving. What "they" do is sending me SYN packest to port 80 from forged IPs, so that my system should send SYN-ACKs to the victim system. In this case it is the Arab Bank. They are down at the moment...I think that is called a spoofed SYN flood attack.
So I thougt the SYN Protection feature should exactly solve that problem but it does not and does not show any "Last Attack" entries.
If I put a SYN filter in place it works, even if I put SYN Rate Protection in place. But that is just a dirty workaround. My firewall blocks those SYN packets with a SNORT rule.
