Spanning Tree is not an option. The Network contains Switches from different Vendors and Spanning Tree is not compatible enough. If your switches don't at least support MST which has been around for almost 10 years now, replace that garbage. Disabling spanning tree is the most incorrect solution to the problem.

I had solved the Problem by follow the hint from richardb. How i have done this: Set Broadcast Limit to 30% Setting up loop-protect for all Ports All loops are detected from now.

What you are describing is what happens when a switch's CAM table is full, where it can no longer learn MAC address and it forwards packets out every port. It might be hard to figure out if this is the problem with an unmanaged switch, but with a managed switch you should be able to display the CAM table. What also would help in this question is a diagram ...

I hadn't seen any snmp guides using snmpv3 and scp as transport protocol. For those looking to implement, here is what worked for me. As with the other snmp config copy guides you will need to download the respective MIBS and load them in the snmp.conf file. This post will specifically cover the snmpset commands for a v3 setup. SNMP Environment: Name ...

Its a bit hard to follow what has happened based on your description - but try "show auto qos interface fastethernet 0/1" and see what it tells you You can find a good description of everything Auto QoS will configure and its expected behaviors @ ...

This doesn't work. A switch runs a highly specialized operating system that usually lacks all the infrastructure that is required to run a chef client and it doesn't allow to install software on it anyway. (Edit: There might be specific switch series that have the required infrastructure and e.g. Run Linux as an OS, but this model doesn't). So, you can't ...

There is no single protocol for managing switches or other network devices. There are a few systems which allow a single management interface, which is then translated into the native configuration for the device (hopefully with some degree of fidelity); but these are neither standardizes or widely deployed.

This answer is pretty vague, because your question is too. Drop a comment if you add info to your Q, and I'll do the same. Most switches don't have a flow path tool per se. So what you'll want to do is use the switch to determine which ports are blocked via STP. That, coupled with your knowledge of the physical layout, will let you know which cables are ...

With DAC cables, I usually let the switch dictate compatibility. Go with what is known-good on the switch and work from there. The other part of this is your balking at prices. Part of working in this field is vendor management and establishing vendor relationships. There's almost always a better pricing option; especially with HP equipment. Try some of ...

No, there is no equivalent on Procurve gear. If you baulk at HP prices, your best option is probably to look for a third-party supplier that will sell compatible parts with the SFP+'s coded as HP.

In my experience, an "accelerated port" is typically a port on a piece of hardware that is accelerated for a specific use via vendor-specific methods. For example, Citrix's Branch Repeater "accelerated ports" to which WAN acceleration is applied. If you have a VTC switch the accelerated ports may have algorithms applied to their traffic (via software or ...

You can't remove configuration rules that set values with the [no] syntax; the way to remove them is to set them back to their default value, which may involve RTFM. So if you have the two rules DarkMoon gives: aaa port-access mac-based 9 aaa port-access mac-based 9 addr-limit 32 they are disabled with: no aaa port-access mac-based 9 aaa port-access ...

It's already off. Use show port-access mac-based to show the status of each port. What you have in that config is the address limit for each port, but have not enabled mac-based auth on any of them. Usually, for a port that has it enabled, you should see: aaa port-access mac-based 9 aaa port-access mac-based 9 addr-limit 32 The two lines do different ...

Swap it out for a different working switch. If it is still broken then your network topology HAS changed.

Access ports not in the VLAN that the unicast or broadcast originates from don't receive that traffic in the first place. That's the point of VLAN's. The excerpt from that article is making the point that instead of dealing with that traffic, if no access ports exist in the originating VLAN on a particular switch then VTP pruning "prunes" that traffic from ...

The only time I see it causing a problem could be an STP issue ( I can't tell without seeing a detailed diagram). If you don't have a very complex network structure, I don't think there will be any problems.

Yes, this switch can act as an NTP server. There are different ways to set it up, namely client/server, symmetric peers, multicast and broadcast modes. Most often you will likely set it up in a client/server mode. For this to work you need to set up NTP synchronization on the switch itself and then it can act as a server for other devices on your LAN. ...

Check the output from dmesg What does route -n say ? What is the output for the internet pointing interface from ifconfig ? Can you ping the default gateway ? Also, check if there is not a problem with subnet masks on the switch ports as well as on the production servers.

You don't need to do any routing tricks for that, nor do you need a virtual interface. You simply shape your traffic as it leaves system A. Outline exactly what you want to do and it is trivial to write a 'tc' rule for it. For example, say you want to limit A to 1mbit/s on all outgoing traffic: # Flush tc tc qdisc del dev eth0 root &> /dev/null ...

Some ideas: You can even shape the outgoing traffic coming from A and B even on GW! If your switch were a little bit smarter... doesn't it have an embedded linux? If you route that through B, beware, some network flag settings will be needed on B to handle the arp redirects correctly. The main problem with your solution, that it will make the network of ...
