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 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.

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?
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'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.
View 1 Replies View RelatedI 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.

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?
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.

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?
View 2 Replies View RelatedI have two 2960 switches connected with two links.

View 1 Replies View RelatedI 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?

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?

View 4 Replies View RelatedWe 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?

Two week ago I bought the TD-W8970 ADSL router model. Im using a canon pixma IP4700 printer connected to the router USB print server port and everything is working without any issues if I just look to the router functionalities.
However since that Ive installed TP-LINK USB Printer Controller, my both computers (desktop with windows 7 and laptop with windows 8) are getting very often some BSOD.
I was editing all files automatically generated by windows on this cases and if seems that the cause of this issue is the file TplinkUDSMBus.sys (installed by USB Printer Controller).
To check the impact of this, Ive uninstalled the TP-LINK USB Printer Controller software from my laptop and I dont have any BSOD since 5 days ago. In the desktop Im still have the same issue.
The router print server is a nice functionality and I really want to use it.

I am trying to set up port forwarding on this router but it seems I need to use virtual servers but in all the guides there is a menu for this under the advance settings nat menu.I do not have that option, I have downloaded the latest firmware but still nothing.
when I connect my DIR-655 to the Motorola SB6141 cable modem I notice that the link speed LED on the cable modem never glows blue indicating a gigabit connection, it only glows amber indicating a lower negotiated speed. I am using a Cat6 cable between the two devices and have also tried a Cat5e cable.
When I try and force the WAN port speed to 1000Mpbs in the router interface the cable modem link speed will not light at all with no connectivity. Only resetting to Auto WAN port speed restores functionality albeit at the lower negotiated speed setting.
I'm running the DIR-655 rev B1 at 2.03NA firmware level.
I did connect the modem directly to my PC that uses an Intel Gigabit ethernet card and still had the lower connection indication (Amber) so it seems that the modem might be faulty.

I have a BSNL BB connection. When I use the connection directly, without adding TP Link router, all the websites open flawlessly. Once when I connect the wireless router, certain websites for example Yahoomail, pepperfry.com, yepme.com don't open at all. These are just examples, but I'm unable to access many sites which is a bit annoying. But sites such as gmail, youtube, facebook open clean, there are no issues. I didn't make any configuration changes too. I tried it more than three or four times, but there is a restricted access only.
We have a customer who has a network consisting of two ISPs, one as a primary and the other as a backup. We are trying to create a configuration that would allow the primary link to fail and the secondary link to automatically pick up traffic and begin routing .how to set something like this up. Both routers are non Cisco routers and there for HSRP is out.
View 14 Replies View Related I have a DIR-655 Rev B, in a typical cascaded config: modem > dir-555 > switches & devices, etc.One of the four dir-655 ports is connected to a cheap-o Belink Wifi router which I use as an access point (I only use this because there's one device that only supports WEP). I was debugging a WiFi issue and I pulled the plug on this Belkin just to get it out of the picture. Well, when I did that, EVERYTHING that was connected through the DIR-655 lost connection. (Well, all the wired stuff anyway- not sure about WiFi devices through the DIR-655). I noticed that the port link light for the powered-off device stayed on on the DIR-655. When I unplugged the cable from the DIR-655, everything went back to normal.
So what I'm trying to figure out now is, is this a DIR-655 issue, or is it something screwy with the Belkin? Or Both? I've got to assume that there's some inherent flaw in the DIR-655 that allows something connected to a port to screw up everything that it's hosting.
I'm in an issue w/ on of our ISPs. We're using an ADSL line as a secondary light load line ( 16 MBit, /w PBR in place to separate the 80 and 443 from the business-critical applications running via a SDSL link. ).
I am on a 2611 XM with IOS 12.2, mated to a D-Link 321B modem running in transparent mode. After running smoothly for weeks, for a few days now, every night some time between 2 AM and 4 AM the link would die with the dialer showing:
Virtual-Access1 is up, line protocol is down Hardware is Virtual Access interface [code]....
To my knowledge, the only option to bring it up again is to reload the box . Taking into account that the router is our DHCP server and the date gets reset to 1994, interesting effects are the outcome of resetting the box.
Well, the ISP have checked their gear and keep saying that these report a "port error" ( quite unspecific ) and blame me that I have a wrong. config in place - which is here:

What ISP Service do you have? Cable or DSL? Cable (link speed independent of internet speed)What ISP Modem do you have? Stand Alone or built in router? Separate Motorola ((link speed independent of modem)What ISP Modem make and model do you have? Does not matter, router issue.If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems.To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged. Not bridged
Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic. Independent of issue, not a factor
Turn off all devices accept for one wired PC while testing. Wired works perfect.Check cable between Modem and Router, swap out to be sure. Cat6 is recommended. Wireless issue.
