Patch panel and LAN distance
Well, I am learning lot through the books on network configuration and network topologies and technologies. They do cover very little about wiring in the real world. If a ethernet LAN segment has a physical distance limitation, then is it possible to extend this distance using patch panel. Are patch panels used only to change the LAN landscape without physically moving the equipement? What are the other uses/functions of having patch panels?

Subnet mask in Network Addressing
I am trying to determine the IP addresses assigned by a local ISP. The address pool comes from a Class A network with a 27 bit subnet mask. Is it subnet mask used only to determine the number of IP addresses in a subnet, regardless of the network class? -- Oscar Rau [EMAIL PROTECTED] **NOTE: New CCNA/CCDA List has been formed.

Modem port on the Router
There are 2 serial interfaces on my Cisco2600. There is also a asynchronous port on the Cisco too. In the "interfaces" section, they are declared as interface Serial0/0 interface Serial0/1 interface Async75 From the software config, without looking at the HW box, how can I identify the modem interface on the router. The Serial0/0 and Async65 interfaces do have ip addresses on them. There is nothing defined for the Serial0/1 interface. The "line aux 0" has one item, speed 128000 Which one of these is the modem interface to the router? -- Oscar Rau [EMAIL PROTECTED] ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
IOS Firewall Feature set vs PIX
This is a bit confusing when it comes to Cisco security products. What is the advantage of buying a PIX when I have a Cisco IOS with the Firewall feature set? It looks like it is doing a lot of packet inspection too. Does IOS Firewall feature set support stateful information? Please let me know any major advantages of using PIX over IOS Firewall feature set. Thank you in advance. -- Oscar Rau [EMAIL PROTECTED] ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Adding HW to PIX
Hi, The PIX system we have only has the inside and outside NICs, which are default. If I were buy a 3Com card off the self and use it to connect to the DMZ, would that effect PIX in anyway. Would PIX recognize this new network HW? Is it something that I have to buy only from Cisco? The difference in cost is big $$$. Any advice or exprience appreciated. TIA. -- Oscar Rau [EMAIL PROTECTED] ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
MAC address
While an IP packet is being packaged to be delivered at the Ethernet frame stage, how is the destination MAC address determined? Is the destination MAC address going to be MAC address of the local gateway or the remote host? Is the MAC changed by the network devices (routers) along the way until it has been delivered to the destination Ethernet IP address? If a MAC address is, 01 23 45 67 89 11 Which half is the vendor specific portion? Where would the multicast bit and locally administered MAC address bit be located?

Documenting PIX config
The recent releases of IOS seem to begin supporting adding coments to the configuration. Is there anyway to document the Cisco PIX configuration?

PIX and NAT
We are implementing a DMZ which will be using public IP addresses. The DMZ systems interfacing the PIX interface will have a public IP addresses and not a private IP addresses. In this case, can GLOBAL/NAT statements be still used to add any valuable security to the DMZ systems? Is there any point in using NAT, because we do not have private IP addresses to the DMZ systems? Any thoughts/ideas for this solution appreciated. Thank you in advance.

Bus Topology and Ethernet
I was reading about network topology and they say that an example of bus topology is Ethernet network. Wouldn't ethernet network be a ring topology due to hub/switch environment? Please correct me where I am wrong. Thank you in advance. Oscar Rau [EMAIL PROTECTED]
ATM
Hello, This is a very basic question about ATM. Since ATM is a LAN technology, I would like to know the maximum distance of ATM network. I would like to know if it can be implemented on a very wide campus network as the backbone. If ATM is used in a MAN network backbone, what type of connections are used between the differrent regions in the MAN? Is fiber used for connecting the different regions or is it a Frame Realy, ISDN type of connection? Thanks for any info. -- Oscar Rau [EMAIL PROTECTED] ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: WAN question
On 0, "Taylor, Don" [EMAIL PROTECTED] wrote: HDLC may be used between routers and routers, routers and mainframes, and mainframes and mainframes. It's all over the place; that's why it's a standard. It doesn't have to go over a WAN - it can be back to back - but it certainly can, though never over POTS. POTS stands for Plain Ol' Telephone Service, which is limited to 56K (and further limited to 53K in the U.S. by the FCC), so there's no way that higher bandwidth technologies can be used over it. Besides that, it's asynchronous, whereas the others you mentioned are not (well ATM kinda is...). POTS is a WAN technology, but it's not a protocol like PPP or SLIP. The only way a WAN protocol (other than async) would use POTS, that I can think of, is as a backup method. - Don -Original Message----- From: Oscar Rau [mailto:[EMAIL PROTECTED]] Sent: Friday, May 19, 2000 7:52 AM To: Cisco GroupStudy Subject: WAN question I have some questions about HDLC and WAN protocols. Is HDLC via serial interface between router and mainframe? and between router and router? If HDLC is done between router to router, is it over WAN using POTS? Do WAN technologies such as Frame Relay, X.25, HDLC and ATM networks use POTS? Thanks you for any info. -- Oscar Rau [EMAIL PROTECTED] Thanks for replying. I will go to the more basic level of this question. For PPP, ISDN, DSL type of WAN connections, you can use the analogue phone lines at home. What about for Frame Relay, T1, T2 etc. type of lines? What medium is used for these WAN connections? I was under the impression that it is POTS (analogue lines) with specialized equipment.

Cisco Training Partners List
I am trying to locate Cisco Training Partners locally around the Great Lakes region of US. I would consider national training partners too. The cisco web site lists very few training partners from the US. Some of the courses that I am looking for are not even listed in any of the training partner sites that were listed at Cisco. If anyone has links to Cisco Trainers sites, please forward that information.
