I would like to set up "IP SLA" between L3 switch(supports many "IP SLA" versions like "UDP Echo Operation", "TCP Connect Operation", "UDP Based VoIP Operation", "ICMP Echo Operation", "FTP Operation" etc) and GNU/Linux server. Are there any "IP SLA" test types which are supported only between two Cisco devices?
View 1 RepliesI'm trying to connect Switch 3560 to NTP Server based on Linux, the NTP is working fine but the switch is sync with the Server:
address ref clock st when poll reach delay offset disp
*~10.0.0.70 208.53.158.34 3 42 64 377 1.7 -2.49 0.1
* master (synced), # master (unsynced), + selected, - candidate, ~ configured
Clock is synchronized, stratum 4, reference is 10.0.0.70
nominal freq is 119.2092 Hz, actual freq is 119.2093 Hz, precision is 2**18

But server has on time and the Switch another. I test this NTP with CUCM and is working fine, the issue is with ther server?
I have a lot of reading to go through but so far everything I have found is for web server clustering.

(Setup routing and iptables for new VPN connection to redirect **only** ports 80 and 443) Only my goal is a bit different. I am running a headless gui-less install of Ubuntu Server 12.04 that is being used for a variety of different purposes... I would like all traffic to travel un-prohibited through my ISP except for my transmission traffic. I have a VPN i subscribe to that allows me access for which I only want to direct a single port's traffic to. I am currently using a modified version of the code from the above link.

In the past a used an RVS4000 as a VPN server for my company, but since I recently moved my company to China I would like to use it for a different purpose if it's possible. What I would like to do is the following:
Use an ADSL router to create a LAN networkConnect my RVS4000 to the ADLS router and use it as a switch instead of a routerUse the RVS4000 to connect to a VPN server abroad over L2TP or PPTP . This would allow me to enjoy the best of 2 worlds:
Enjoy the full broadband speed of the LAN network created by the ADSL router for normal internet useHave a separate wired connection permanently connected to VPN giving access to company email etc... My question is: Is this actually possible?
Can the RVS4000 be used as a switch?When used as a switch, can the RVS4000 still be used a 'VPN receiver'? I'm possible trying to do the impossible, because I would have to have the ADSL router have to act as a DHCP server and disable DHCP on my RVS4000 in which case it is probably impossible to have the RVS4000 act as an L2TP/PPTP VPN receiver.
I'm pondering this new client's topology. He has: (internet) >> router >> switch >> Windows server with a VPN enabled.
Right now I access his network remotely by just RDP directly into the server with a public IP address.Now doesn't this mean that I'm already sailing through his router and switch? Doesn't that mean that all (broadcast, routing, etc) communication hitting this IP is sucking CPU cycles and bandwidth on his router, switch, and server? Wouldn't it be best if he had his VPN endpoint set on his gateway?
when we use switch as dhcp server and we want to configure a DHCP relay on other subnet that is not connected to this switch, what is the DHCP server ip address for configuration of DHCP relay? Should we use vlan1 ip?

View 1 Replies View RelatedI have some unused 10G NIC's and want to see if there's a way to install them into a computer and turn that PC into a switch. I need to run Windows based software for driver support of the NIC's, such as Server 2012. This is a picture of what I am hoping to accomplish:
[PC1] -----10G------[PC2]------10G------< Hardware Switch >
| | | | |
1G 1G 1G 1G 1G
| | | | |
[PC3][PC4][PC5]......
As you can see in the simplified picture above, I have a real switch which has a single 10G link that is connected to PC2. I would like to add the 10G cards to PC2 so that I can create a "switch" of 10G ports on PC2 which I can then hook up other clients (such as PC1 in the above picture).
PC2 needs to provide network access and internet access to PC1 (and other PC's connected to PC2 - not pictured).
The rest of the clients on the network are connected to the regular gigabit ethernet ports of the hardware switch (including my router which is 192.168.1.1).
I looked into Windows Internet Sharing, but for that to work, I need to connect the router to PC2 above and for other considerations not described above, it is not physically possible for me to do that.
Is there software I can run on PC2 that will turn all the NIC ports of PC2 into a "switch"?

View 1 Replies View RelatedI am sutdying at uni and in a few months, I will be moving into a house, with my current flatmates. We will be buying a fibre optic line.Ideally,what I want to do, is split the connections evenly,depending on how many people are online current, rather than having mass downloads of everyone at the same time, when other will only get a small speed while browsing or gaming,or streaming,etc.So, basically, what I want to do is split the connection at anyone time evenly,so if there are 5 people connected and our connection speed is 50MB then each will get 10MB. And if 2 people are connected, then the speed will be 25MB each, and so on.
I am wondering what is the cheapest way of doing this? I am very computer illerate,I know how to use unix systems.I even own my own server, but I'm not so clued up in this area of networking.I believe it's something to do with a switch, and which switches support this? (I've heard it's something to do with full-duplex / half duplex).
- I will probably set up a domain system, where everyone has to login to the main server to access the internet. (I know vaguely how to do that) - is there some software that I can put on the server which will distribute connection speeds automatically.
I'm due to replace a stack of 2 x 3750 switches very soon with 2 x 3750Gs. These 2 current switches are the VTP server for a small domain. I have put the config on the new switches switches and I made it a server and used the same VTP domain and password etc and got the VLAN info ported over.Now I did this a while back and noticed the switches are in transparent mode with a revision number of 0, I need to set this back to server and swap the switches out but the revision will be lower than the client switches (around rev 200), what do I need to do?

I want to replace an existing 3560 Switch with another switch of the same exact model and IOS. However, this switch that needs to be replaced is the VTP Server of my LAN at this location. When I replace the switch I will just use the same exact running config but I'm concerned about the vlan.dat file. Do I need to copy that file over to the new replacement switch and if so, what is the best way to do that?

View 1 Replies View RelatedI am having a problem configuring NAT for a Linux device on our network. I am far from a Cisco expert but I have configured this many times in the past for Windows machines quite easily. I do this using the Cisco ASDM 5.2 for PIC GUI. All I needed to do for the Windows machines was:-setup the static NAT rule(inside ip translated to outside ip)-create a security policy(outside, incoming rule) to allow traffic to the outside ipand hey presto it works, ie: i can ping the outside ip and access the device remotely if I have allowed correct ports.I am not sure if this is the correct method but it was how i was shown and has worked many times in the past.But with this Linux device its no dice. The Linux device isnt a desktop but a mediator for industrial air conditioning controls. It runs a web server which we can view temperatures etc... through a browser. This works inside our network by browsing to the inside ip but I am trying to set it up to work outside of our network.

For example, we have three Linux machines in production, each in three separate V LAN's. For me to communicate to these boxes from one V LAN to another I must first ping the server. If I do not ping the server it will not bring up a connection like ssh or HTTP, etc. Below is the error I get from the FWSM that hosts the Linux server, but like I said once I ping the server the error goes away. We only have this problem with Linux machines, and it is a problem for all three of them. Is the FWSM having issues understanding something with all three Linux boxes? Below is the error I get at first, when I try to SSH from one V LAN to another V LAN with the Linux machine.

Below is what happens when I initiate a ping to the Linux Server and then ssh again. Notice it builds the connection with no problem after the ping. During the ping it builds the dynamic translation, and then when I ssh it builds the TCP connection. Do you know why this could be?
