Network Analyzers [7:72346]
I work for a small growing business and am currently evaluating two types of network analyzer software. EtherPeek NX and Sniffer Portable (Sniffer Pro). Since the versions that I have are not the full production versions (only for evalutation purposes), I am limited to the functionality I can do with each. I know there is an extensive difference in price (Etherpeek NX is somewhere around $2000-2500 range, and Sniffer Portable (Pro) is somewhere greater than $10,000. For a small growing company, it is hard to justify over $10,000 for a piece of software, when I can get something comparable for much less, especially when we are in a time where we have to justify our jobs. What I would like to know, if anyone has experience with both of these applications, and what capabilities that Sniffer Pro offers, that Etherpeek NX does not. I would also like to know if anyone has experience with Ethereal (for Linux). I know it is free and it has much less functionality than Etherpeek NX or Sniffer, but I would like an opinion on that to. Thanks.

6509 MSFC [7:71340]
I have a MSFC on a 6509 that I am firing up for the first time. The 6509 is running CAT-OS (Hybrid Mode). I have defined several VLAN interfaces on the MSFC, and now must create a specific access-list to limit only a certain source and port address to reach each of these VLAN's. This access-list will not allow Telnet connectivity. My question is, if I create this access list and bind it to all VLANs, will I be able to SESSION over from the switch to the MSFC? Does the SESSION command actually use Telnet to get to the MSFC? Will I need to assign a loopback address and then allow access to the loopback address specifically in my access-list? I just want to make sure that I do not block all access to the MSFC. Any clarification on this would be helpful. Thanks.

RE: 6509 MSFC [7:71340]
Actually I think I answered my own question. I believe that it does telnet, but uses a system default Loopback address (127.0.0.x). When I session over, it shows that I came from 127.0.0.y. Any thoughts...?

VTP Domain Server Question [7:70942]
I have a question regarding VTP. I am working with a network configuration that has dual 6509's as core switches. One is the VTP domain server, the other is a VTP domain client. All other 4000 switches are defined as client also. I need to take both 6509's down to upgrade the Cat-OS on them, however I am concerned about what happens to the other switches when the VTP domain server goes away while the other 6509 is in client mode. I know that I can assign multiple VTP servers to a domain. My original thought is to first make sure that the client 6509 is running the same VTP revision # as the server 6509. Then I should be able to change the client 6509 to VTP server mode. Then in theory either server can take over VTP responsibilites, because one will be able to act as the other if the other one goes away. What I was also wondering, do all VLAN's go disabled if I were to only have a single VTP server and shut it down when the rest of the switches are clients? If so, would this happen right away, or after 5 minutes? If I take the 6509 server down, it will not be able to tell anyone that a topology change has occurred, but will the clients be looking for the VTP 5 minute updates? If anyone could help clarify this, I would appreciate it. Thanks. Dave C.

RE: Help with router config [7:69612]
No this is not correct. You should not see an entry of 192.168.0.2 in your route table. All you should see is a route to 192.168.0.2/30 (which means two host addresses). It looks like you have a subnet mask conflict possibly on the other end. If you want your configuration to be: router 1 192.168.0.1 router 2 192.168.0.2 then you need to make sure that both IP addresses have a subnet mask of /30 (255.255.255.252). Generally /32 (or 255.255.255.255) is used for a loopback interface. Since the route is being learned via Serial1/1, I would have someone verify subnet mask info for that interface at the other end of the circuit. You may want to verify your configuration too just to make sure that there are no secondary addresses configured or something strange like that... Thats my perspective... HTH...

RE: Help with router config [7:69612]
I am sorry, you should see a connected route of 192.168.0.0/30 in your route table. (Not 192.168.0.2/30 or /32). I appologize for the typo, but its been a long day! HTH...

RE: CCIE Lab - Boson Router Simulator [7:66367]
I just wanted to let you know that I purchased the Boson Router Simulator when I was preparing for my CCNP exams. Looking back, I feel it was certainly not worth the investment. I thought that this may save me some money over buying a couple of routers on eBay, but I would have been better off with the routers. I spent a lot of time trying to figure out what was wrong with the simulator. Things as simple as configuring a P-P Frame Relay circuit. I was never able to get frame-relay to activate. Some IP routes would not refresh correctly until a different routing protocol was loaded and unloaded. I could go into more detail, but I do not think it is necessary. Then I would have to document these issues and send them on to tech support and wait a day or so for a response. It seemed to slow me down in my progress. Do not get me wrong, the simulator is a good idea (I think if you are trying to get your CCNA). For the complex scenarios we have to learn for the CCNP or CCIE, there is no replacement other than a network of actual routers. Hope this helps!
