I was told to implement 100% end-to-end redundancy (from the distribution switches to the servers). We have nine racks of servers for this project. Each rack will get a primary access switch, and a secondary access switch. That is a total of 18 access switches. These switches will all have...

Hello, We have a hub and spoke frame relay network. All routing is static. Each remote end has one physical circuit installed. Our frame relay provider has it set up so each circuit has TWO DLCIs. One PVC is currently going back to the "hub", or the main distribution router. The other PVC...

Hello, I am curious to see what everyone's best practices are regarding VLAN 1. Does anyone use it? "Disable" it? Avoid it? I know there are some features that utilizes VLAN 1 (such as CDP), and I am curious to know if this will effect any of my services. We have a Solarwinds Orion server...

Monitor the CPU, memory, and overall bandwidth load. Check the interfaces for input/output errors and drops. What kind of routing protocol are you running?

Hello all, I work for a company that is trying to provide internet services for a garden style apartment complex. The complex is about 10 different buildings, scattered within a 3,000 foot radius. The buildings are about 50 units each, and are no more than four stories high. We will have a...

So you are running IPSec and EIGRP on a 837 router? Thats impressive. Mine can barely handle NAT, a GRE tunnel, and a few access lists. Just what themut said, the unexpected reload could have come from your router crashing.

One of the machines could have obtained a virus and is flooding your NAT table with continuous entries. Do a.... "show ip nat stat" and "show ip nat trans" to see how many entries you have in your table and from where they are coming from. When there are over 10,000 entries, your...

Forgot to mention about the clock source. You may need to specify that on the interface - "clock source internal", for example. Whatever the case, the local port configuration must match the remote port configuration.

I apologize as I was thought you were using channelized port adaptors. If you are using a PA-2T3+ card, then forget what I said about the controllers. I may be overlooking something else with your configuration. Like I said its been a while since I last worked with DS3s (Im stuck in cable world...

You dont have the controllers and the timeslots defined. I dont have a VXR in front of me, but I believe the global configuration command is... "controller T3 x/x" (where x/x is the slot/unit number) From there you can specify the framing type, clock source, linecode, and the timeslots...

Wybnormal brought up a good point. Why do people spend thousands of dollars for expensive VPNs when more cost effective solutions are potentially available? If I need to secure a SMTP connection between two nodes, for example, why not just forward it via SSH (v2 of course)? The cost is...

Greatly appreciated gconnect. That information was very helpful...

You need to put "ip nat inside" on your ethernet interface as well. LGarner forgot to mention that, a very rare mistake for him. Whats wrong lgarner, hurrying to get out of work for the weekend? =)

I have a network right now with about 100 residential users. Unfortunately, I was only able to obtain a /28 block of public IPs....so I implemented NAT on my core router (7206VXR) to accomodate everyone. The problem is - my customers have been killing this router's NAT table. Last night one...

Is the Cisco default on a router = weighted fair? Just wanted to confirm. Thanks...

Thanks Degg, another helpful thought. Actually, the contract is with SBC....and the CIR is listed at 1.544. Like I said in a previous post, I ruled out SBC because my DIA workaround (1721) is working great. I havent had a single performance issue yet. Same frame relay circuits, same...

Did you ever figure out what was wrong?" Unfortunately no. I classified it as hardware failure, with the PA-MC-8T1+. Instead of terminating the 2 T1 DIAs directly to the port adapter, I have them running into a 1721 instead as the work around. The configurations are basically exactly the same...

Cisco makes high quality wireless products, but there are other solutions out there for those who are looking for something more flexible and cost effective. Tsunami has equipment that range from 16Mbps to 872Mbps. It can carry voice, video, data, etc. Orinoco makes some access points for the...

- show ip nat stat - show ip nat trans - show proc cpu - show proc mem Check your NAT entries. There could possibly be one or two computers with a virus that are beating up your NAT tables. The more NAT entries there are, the more resources it takes for the router to process the information. By...

lgarner, wouldnt policy-based routing work in your case? raphaelmontcho - 27 network bits give you 30 hosts, so the netmask will be 255.255.255.224. The wildcard mask for your access list would be 0.0.0.31.
