during using switches Linksys sps224g4 faced with the following problem.
When the end user is connected in 100 Mbps port of the switch and rtt more than 10 ms to a remote server, the download speed from server in one stream does not exceed 2.5 MBWhen rtt less than 5 ms, the download speed in the one stream 11 MB.
When switching user from 100Mbps to 1Gbps port, download speed from remote server grows up to 11-14 MB.When we connect user to 100Mbps port of another manufacturer switch in one stream download speed reaches 10MB.
Tried to configure next parametrs:
1. Checked for firmware 1.0.2 and 1.0.6, the situation is identical.
2. Enable, disable negotiation on the client port.
3. Turn on / off qos.
4. Turn on / off flow-control.
5. Turn on / off jambo-frame (I do not know how it could have an influence, just in case).
6. During traffic analizing on the users port were found no differences between downloading from servers with rtt 5 and 35 ms.
Pinouts for making a serial cable to connect from a pc to the LINKSYS SPS224G4 Switch?

View 2 Replies View RelatedI have applied port security in one cisco switch and i have enabled port security in one port.I have applied port security as sticky and applied "restrict" on violation of the portsecurity.Now i have connected a PC to that switch port. Later i have connected another PC. The packets got dropped. But when i connected the original PC again, the packets flow started again.So, i have a doubt. Will the packet flow get establish, when the original PC is connected again to a port which is applied with port security violation "Restrict"?
View 2 Replies View RelatedWe 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?
I'm trying to setup an ACL on my SG300-20 to enable FTP and a few other protocols to a server, but I'm running data that returns on different ports (ie active FTP).
Below is a sample:
-------------------------------------------
Extended IP access list Protocol_Restriction
permit tcp any ftp any any
-------------------------------------------
Now that works great to allow a connection, but with active ftp when the data tries to come back on a different port (I assume) it is just hung up as all other ports are denied.
I event tried allowing all ports to come back from the server:
-------------------------------------------
Extended IP access list Protocol_Restriction
permit tcp any ftp any any
permit ip any host 192.168.0.100
-------------------------------------------
But that also didn't work seem to work.
I've played around with this in layer2 and layer3 to no avail. I've also seen many tips on applying in and out to the various interfaces, but that doesn't seem to work. Is that something that is only available on higher end switchers/firewalls?
I just want the switch to be quiet so that I can perform some network testing with only the connected hosts showing up in my traffic analysis program. But every 30 seconds or so the switch sends out an LLDP packet. This switch is only used in the lab for running tests so I know I don't need the LLDP feature running.
This article explains how to disable LLDP globally on a Catalyst switch, but I can't find any option to disable LLDP in the SGE2000's configuration menus.
I would like to deploy this kind of configuration (See attached network plan).My questions are:
1) is possible to enable etherchannel links between different switches, without stacking links?
2) how is the expected bandwith consumption when I enable etherchannel PAgP or LACP protocol?
I have not been able to find the option to turn on LLDP for our Polycom (Lync) Phones. Is this not an option for this model router (C1861)?

I will say that these 5548s are serving as the distribution layer for a UCS chassis (2x 6120 FIs) but didn't know what kind of visibility the Nexus would have into that - the chassis keyword is what's alluding to this in my mind, and I'm seeing these messages whenever interfaces that connect downstream to the fabric interconnects are brought up or down.
I would like to know cisco 3560X-24P-S will support LLDP & DHCP relay .If it support which IOS feature is required to enbale these features.

I recently purchased an SG300-28P. I have 2 VLANS/subnets that are successfully routing between them.Machines on both sides can ping each other just fine, but none of the usual Windows/NetBIOS browsing is possible. I've recently learned that NetBIOS is not usually forwarded between subnets. How would I enable NetBIOS packet forwarding between my subnets?
Reading the manual, it seems like enabling UDP Relay might be the answer but I've been unable to get it to work (same with DHCP relay).
when I try to enable network internet connection on my computer it tells me that somebody else is using IP 192.168.0.1

View 1 Replies View RelatedIf I have two stackable switches one switch uplinks to one 6509 core switch and the other connection uplinks to another 6509 core switch, and also the other stackable switch does not connect to the core switches. Because I am using hsrp and also we are not using vss then one uplink to the core is not in used only ones is so then how does creating an etherchannel between does two uplinks to both core switches benefit me in anyway such as more bandwith and using both uplinks at the same time or I'm I wrong?
View 7 Replies View RelatedI have 2 switch groups.
2 SGE2010's with VLAN's defined as 10,20 and 30
Vlan 10 is the management VLAN, and it uplinks to our border router.Vlan 20 is the workstation VLAN, and all workstations point to the switch as their default GW? Vlan 30 is the ip phone VLAN, and all phones use this as their gateway.
I would like to put a LAG between said switches, we have some servers on the ip phone switch that need to be accessed by the workstation clients, and the single 100mb link through the router is probably not going to be enough.As I understand it, because the switches have different networks on them, a simple lag will not work. I did create a lag, and assign ip addresses to each side, however in that mode, it doesn't appear I can block vlan 10 from transiting the LAG, and with out that block I will end up with a logical loop, and spanning-tree will block one of the uplinks, or the LAG itself.
If I have two stackable switches were only one stackable switch has two uplinks one uplink goes to one core 6509 switch and the other uplink goes to the other 6509 core switch can a Layer 3 etherchannel be used if each uplink go to a different core switch, by the way hsrp is running between both switches and also can you give an example how data will be routed from the stackable switch through the ethernetchannel to one of the core switch accross the WAN to another core switch?

View 1 Replies View RelatedWe 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.
