Cisco Switches :: SG300 Link Aggregation And Wake On Lan?
Aug 21, 2011
Having issues waking NAS devices using a magic packet when using link aggregation on an SG300-28 switch.
Without link aggregation everything works fine so I know the magic packet is being generated correctly and the NAS device is correctly configured to wake. After configuring link aggregation the device does not wake. Have tried dynamic (LACP) and static link aggregation but neither allowed the device to wake? When the NAS is powered off, the ports in the LAG still show as being connected at 100M but it appears the magic packet is not being transmitted.
I'm trying to setup Link Aggregation on this switch for an HP server with a 4-port NIC which is teamed. I create the LAG and see in the HP Network Utility where each port in the team disconnects then reconnects and the server has internet access, but workstations cannot access the server (can't browse UNC, RDP, ping, etc.) and vice versa. This is the only switch at the site, all the workstations are plugged into it. Rebooting the switch after creating the group didn't have any effect.
I have a Synology 1512+ and trying to setup Link Aggregation but no success. I have configured LAG Management with LACP enable or disable but still failed.
At the Synology 1512+ setting page, there are 2 options: IEEE 802.3ad Dynamic Link Aggregation and Network Fault Tolerance (Non-802.3ad network enirovement), I selected IEEE802.3ad, which i think S200-18 should be able to support. right?
answer regarding stacking the SGE2010 switches versus link aggregation if greater than 1 Gb connectivity is required between individual switches? Currently have several switches in a stack configuration but would like to increase the bandwidth between some or all of the switches. Does stacking support a link aggregation configuration? If so what ports can be used and how should the link aggregation be configured in conjunction with the stacking?
We have a pair of N7K distribution switches connected to a pair of N7K Aggregation switches.We run vPC on both pairs of n7k's.
-n7k-d1 has two interfaces in a Port-Channel connecting to n7k-a1 & n7k-a2. (PC1) -n7k-d2 also has two interfaces in a Port-Channel connecting to n7k-a1 & n7k-a2. (PC2)
My problem is that Spanning-Tree is blocking PC2 and all traffic from n7k-d2 is traversing the Peer-Link before reaching the Aggregation layer. Is this the best design for connecting two pairs of n7k's with vPC or if a better design would be to connect all 4 links into the same Port-Channel and vPC?
I have two switch SG300-10 that need to be interconnect togheter with a simple redundant "cable fail safe" configuration.My idea is use the two uplink copper port of the first switch, connected to the two uplink copper port of the second switch.
How to create a working setup configuration? The first setup that i need, is with only one VLAN1 for all ports,
The second setup is with the VLAN1 assigned to the ports 1-2-3-4 of all the two switch, (linked togheter by uplink ports) and the VLAN2 assigned to the ports 5-6-7-8 always linked togheter with the same uplink ports.
Is possible use the two uplink port at the same time, as cable fail safe? or use a uplink port 1 for the first group and the second uplink port for second group?
I need to use this configuration for audio cobranet transport, and i need to test the correct configuration for the primary and secondary audio stream, if can work togheter on the same VLAN or i need to separate the two stream, from start to the end.
whether VSS technology support on 3560 switches.I'm planning to intergrate new Cisco 2x6509 with VSS and all the access swtiches 3560's uplink to core 6509..if not support, what will be the solution or any bug fixing or new IOS releasing
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
what is the difference between "link aggregation" and "STP"?
For example: I have two switches connected with two ethernet cables together. Why I will use link aggregation on trunk ports (without load balancing) when STP will do same service?
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?
We want a solution for routing between N5K and VSS with aggregated WAN links.
DC1: It has 2 cisco 6509 with VSS. There are 4 server farm cisco4948 switches connected with VSS with redundant uplink via MEC. Server gateway is the VSS. VSS is running Eigrp routing.
DC2: This is a new datacenter we are going to establish soon. We are planning 2 N5K at core layer with L3 daughter card and 4 N2K as server farm switch. 2 N5K will have vPC peer between them. Each 4 N2K will connect with redundant uplink via vPC with this N5K. N5K will run Eigrp routing and will be the gateway of this new DC server.
WAN between DC1 & DC2: DC1 VSS will connect with DC 2XN5K with 2X10G links. we want to do MEC at VSS side and L3 vPC at DC2 side. If we have VSS at both end it might not be a problem. Both the link will work together as 20G aggregated link. But as we are using N5K at one end, so it creates a confusion whether it will work properly is this scenerio or not.Also I would like to know,
1) In VSS I have configured 1 VLAN interface for server gateway. But in N5K do I have to configure at 2 switch seperately?
2) In WAN routing VSS shows as 1 device. Does this 2 N5K will show as 2 seperate hops or L3 vPC will allow them to act as a single device while traceroute from one end to another end.
I am trying to setup a home network where I have multiple low bandwidth or rather lower bandwidth links coming in. They are suppose to be broadband but I do feel the need for a fatter pipe. Since this is in India and we have limited availability of bandwidth options like here in the US I thought if I could double or even get close to doubling my bandwidth using some sort of device for link aggregation or a network / pc setup which can achieve thisThe links I am getting are above 1mbps, possibly even 2mpbs and its relatively cheap, 100$/yr so I can add 3-4 to get desired results. A dedicated 10mbps connection costs nearly 12000$/yr so I have a lot of margin to create a substantial pipe without the cost if what I am thinking is possible.
I've been having some issues lately where if I am copying large amounts of files two and from my NAS and thus saturating my gigabit ethernet, web browsing and internet streaming slows down which is a bit of a bummer. I figured I might fix this with link aggregation.
My switches (Procurve 1810G-24 in basement and 1810G-8 in office) both support 802.3ad Link Aggregation. It works beautifully to connect them together, as well as to connect my FreeNAS box to the switch as well.
how do I set it up to work with my Windows 7 box?
I can't find the options for 802.3ad in the windows menus anywhere, and googling has not led me to the answer yet...
My motherboard has two on board Intel gigabit ports (Intel 82574L and Intel 82579V). Is it possible to link these two, or do I need to pick up another Intel PRO PT dual port copper gigabit NIC like I have two of in my server?
I am trying to get WOL working across different VLANS on a SG-300-10 Switch in Layer 3 Mode. To achieve this, I've setup an UDP-Relay (GUI menu IP Configuration) for UDP-Port 7 to 255.255.255.255 (this should flood all interfaces with the paket), however, WOL doesn't work across different VLANS. When I am connected directly to the corresponding VLAN, WOL works fine within the same subnet.
I am looking after a mixed collection of Cisco and HP switches and use a Perl script to extract configuration data.I use the ifStackStatus table (OID: 1.3.6.1.2.1.31.1.2.1.3) from RFC1573 to sucesfully obtain the EtherChannel data from the Cisco switches but, though I do obtain data from the same table from the Procurve switches it seems to bear no resemblance to Link Agregation. I could look at other tables and may have to - but would like to use this one in order to simplify the code.
We have acquired a cisco sge 2010 to replace our distribution switch. I set up the 802.1X network. Everything works great except I can not find how to enable 802.1x with 'Wake on LAN' on this kind of switch.
On catalyst I saw that it was sufficient to activate this control "authentication control-direction {both | in}" Except that it seems not to exist on this switch. Is there another way to enable 802.1x on WoL without using this command?
Or how to allow the magic packet (WoL) on a tagged port by unauthorized 802.1x?
My switch Cisco small business SG200-26G in modality link aggregation LACP the Wake On Line doesn't work !! (WOL work only in link aggregation non LACP..) I already upgrade the latest firmware but not resolved..
if my SA520w will support link aggregation for network devices within my LAN. If so, is there a Cisco wiki or how-to on how to setup this up in the SA520w? I only find a brief mention of this in Section D of the manaul.
I have two 2960 switches connected with two links. One of them is transparent modem connection with 2Mbps limit, and the other is optical link with media convertos on both sides. Is there a way to set up etherchannel, LACP or any other kind of link transparent to switches or I have to use some sort of STP?
I have two workstations running 7 Pro, each has a quad port intel card (PCIe) which I have created teams for on both sides using link aggregation. On my switch, a Cisco SG500X-24, I set up two LAG's with 4-ports each and have both servers connected as necessary. I turned on Jumbo frames and disabled energy saving. The teams were set up without LACP turned on, however I tried it with LACP and I also ran into the same problem. Both workstations have a 26TB arrays running in RAID 6 (so plenty of read/write speed), however, with this setup, I can only get about 100MB/s (single port speed) and multiple data streams cause the speed to divide. Only single ports blink on the cards as well.
Questions 1 is probably a no-brainer, but it's my first time setting this up, but once this is working properly, would it allow a single file to transfer at ~400MB/s or would I need to start multiple datastreams to take advantage of link aggregation.
Question 2 is what do I need to change to make the link aggregation work?
I do have a little linksys router plugged into a non aggregated port to do DHCP but that wouldn't mess anything up, would it? Considering I can unplug it once everything is talking, all the transfer should take place at the switch level, correct?
Trying to configure my desktop to Wake on Lan. I have the BIOS set to WOL(PME) enabled, i have the ports set up, and everything. I installed a WoL Sniffer on the desktop, and sent a wake up command and the sniffer showed it came through (with the correct FF FF FF FF FF FF <Mac address repeating>). The router it's hooked up to has the UDP port 9 forwarding, ad that's what my WoL tool is sending, and i see the light by the ethernet port and it does indeed flash repeatedly when i try to send the WoL magic packet.However, nothing happens. It's shut down, plugged in, i used the soft shut down from windows,If it was the router, then the light wouldn't flash when sending it...
I just got a d-link DIR-655. I had a WRT-54G before, and Wake on Wan worked fine (was built in to the DDWRT firmware) and so did remote VNC. Now that I have this one, neither work and I can't find wake on wan in the firmware and no outside utilities seem to work. I am using ultravnc and I did forward port 5900. Port forwading works on other things, I think, because I got web access to work for my NAS.
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 been trying in vain to setup my home network so that I can perform wake on lan (WOL) over the internet. I have been able to do WOL with a magic packet utility within my local network - so I know that the PC NICS are configured correctly - but this does not work when I try it from my office for example, over the internet.
I have a virtual server set up forwarding ports 9 and 7, UDP to 192.168.1.101 initially, but found some threads about using the broadcast address so changed this, but still no luck. I had to downgrade to 1.20 from 1.21 as I found several threads here about firmware versions not allowing broadcasts.
My setup is as follows:
Router: 192.168.1.1 PC1 192.168.1.101 (static assigned by MAC address in the router) PC2 192.168.1.102 (static assigned by MAC address in the router)
