Cisco Switching/Routing :: SG500X-24 / Link Aggregation On Switch And Controller?
Nov 4, 2012
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?
We're looking for Cisco switches with the following attributes to serve as the core switches in a production network:1U (or close), fixed config20 or more 1GbE copper ports4 or more 1/10GbE fiber ports (SFP+)Not ridiculously expensive So far the closest fit we've found for these requirements is the SG500X-24. However, since the SG500X-24 is a "small business" switch we're concerned that the reliability may not be up to the levels of Cisco's enterprise switches, the support level may not be sufficient, the 12MB packet buffer may not be enough to support wire-speed operation (or efficient communication between hosts on 1GbE and 10GbE ports), and so on. But in looking through Cisco's entire current switch line (a daunting task...) this seems to be the switch that best fits the specifications above. So, some more appropriate switch that fits the listed requirements?s why the SG500X-24 would be a poor choice for a production network? Have you had positive experiences with using the SG500X-24 as a mission-critical switch?
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?
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.
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
We are running a Cisco 887VA router for our internet access but of course the port connected to the internal network only supports 100Mbit/s. There are a few 100Mbit/s ports on the router; I was wondering whether it was possible to use more than one port to provide aggregation to get higher speed such as two ports providing 200Mbit/s? We are running Gigabit internal.
I need to confirm how many queues actually supports the switch SG500X?. In SG500X_data_sheet.pdf document (pg. 8) say they have 4 hardware queues (8 future) !
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'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 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 am looking to configure a wired and wireless guest network. I have industrial barcode scanners that connect to one SSID and then there is the business network on the office SSID (no vlan seperation for these devices just different SSIDs). There is not really a need to seperate the business network from the scanners in any case. However, there are needs for a guest network and this needs to be seperated. At the bare minumum I would like to have the wireless guest network. Here is what I have: 2125 Wireless LAN controller managing 18 LAPs (1 indoor and 17 outdoors)Cisco Cat 2950 switches (2 x 24 port and soon to be replaced with 2 x 48 port 2960's with 802.1x capability) Sonicwall TZ210 firewallOne existing wired and trunked vlan for PLC infrastructure. One ESXi hosting Windows server guests (soon to be 2 with vMotion) The reason for the wired guest access network is tp prevent anyone from plugging into the wall jack in the office with thier home laptops or anyone else from being on the same subnet as our domain machines. Granted they would be unathenticaed but there would be no layer 2 seperation and that is what I think would be best.
How would I go about doing this on the wireless controller without an anchor controller just using my existing hardware? I would like to have the Guest SSID only availible in the front office. Is it possible to offer a guest network while still servicing the business network SSID on the same access point? Then might I be able to have the guest network be treated as it should at the controller? However this might present another issue altogether as the guest traffic will be over the same wire as the business SSID until it hits the controller for management.
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?
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 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?
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.
I'm trying to use 1142 APs with a 2504 Wireless Controller through a D-Link 48PT GBIT XSTACK SWITCH (DLI-DGS-3120-48PC/SI).At any rate, the 1142 AP joins with the wireless controller ONLY when I attach it directly to the controller. When connected directly to the controller the AP functions normally and all is well. When I attach it through the D-Link switch, the AP flashs green several times, indicating that it can't find the controller. I suspect that there's some setting on the D-Link switch that's preventing the AP from seeing the controller.
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?
I just deployed two stacked SG500X switches. I noticed these messages in the log (see below). Despite these messages everything appears to be functioning.

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?
We are using CISCO 4507R-E switch as our core/distribution switch. Out of the 7 available slots, 3 are currently being used. Descriptions is as follows:
Slot 1: 6 Port Fiber Line Card
Slot 2: 6 Port Fiber Line Card
Slot 3: Supervisor Engine
Slot 4: Empty
Slot 5: 48 Port Copper Line Card
Slot 6: Empty
Slot 7: Empty
We want to add extra 10 Gbps fiber links (approximately 12) using slot 6 and 7.
I have one 12-port 3750 switch having one gig connectivity with ASR-9010 router having IOS-XR. I am not able to ping this link with 9000 mtu size. I have enable system mtu jumbo on switch to 9000 and on ASR router interface mtu is set to 9114. At switch side switch interface is configured as a trunk port and one vlan has been passed on that interface. I am not able to ping the ip 172.16.10.2 with 9000 mtu size.
I have an issue with a Cisco 4900M switch with a WS-X4908-10G-RJ45 half card. The link connection between a 10Gbase-T server nic and the switch does not establish, i believe it is an auto negotiation problem. The link fluctuates constantly between connected and disconnected when set to auto negotiate. When the 10G half card port groups are configured for 1G connections it does the same. If i hard code the server nic to 1G the link remains up when the port group is at 1G. If i hard code the server nic to 10G the link stay down, i don't think the port speed and duplex can be hard coded on the switch end. I have tried updating the drivers on the server as well as diagnostic tests on the nic, which passed. The 4900M IOS code is version 15.0.2-SG2. If i plug a laptop into the 1G configured port the switch and the laptop negotiate at 1G. Also, i believe, if the 10G server nic is plugged into another 1G only switch the link auto negotiates to 1G as normal. The server nic is an INTEL Server Adapter AT 10G, which became end of life in 2009. I believe the half card came out in 2010.
I need 10gigbit uplink for this switch. What are the other devices that i need order along with this device.And what is the diff between X2-10GB-LR= and CVR-X2-SFP.if i take CVR-X2-SFP, in future how can i upgrade from one gig to 10 gig?for current use i need 10gig support required. so what are all the other devices that i need to order.Fiber multimode and distance 15Mt only.
i have an issue to connect a trunk between cisco switch and extreme switch i have many vlans that i want to cross via a link between cisco 3750 switch and a Extreme Alpine 3800 switch
I have two 3750-X configured to be a stack and I am planning to re-rack these somewhere else. What I would like to know is what are the effects of having the master switch itself lose power? Does it immediately just make the member take over master (there should be no election since there are only 2 switches??) and there would be no loss of connectivity?
I have a Catalyst 4006 switch in production and a spare switch of same model. I have to quickly copy the configuration from production switch to spare switch (both L2 and L3 configurations) How do I do that?
Having an issue with my WLC 5500 and client connectivity. This just started today. Clients will connect for a short period of time and then drop off. WLC appears fine with the exception of a bunch of trap errors. I've rebooted the WLC but this did not clear the issue.
