RE: Is CVOICE1.0(1998) enough for CVOICE 2.0 Beta?
I'd took my CVOICE ver 1 training in S'pore 3 weeks ago. According to the instructor the CVOICE 2.0 is basically a subset of CVOICE 1.0 but their material are much more organized. However in the CVOICE 2.0 exam, you can expect the question more towards PBXes (told my the instructor). Taking the exam next week. Good luck everyone.

RE: ISL & VLANS between routers
It can't be done with 10MB interface LAN in the router. For example: Cisco 1600 series and 1700 series is not capable for VLAN routing (although 1700 series has 100Mb interface).

CiscoWorks & HP Openview in multiple VLAN.
Good day, It seems that I'm stuck with a problem on my customer network. I doesn't have much idea about LANE and their existing network setup since it is managed by other vendors so the bottom line is that I cannot view their cisco router configuration at all. However base on their existing updated network schematic design, they have 4 core catalyst switches with RSM module and few distribution & floor switches. My current HP Openview and CiscoWorks configuration pointing the address of the local catalyst RSM IP with SNMP read-only enabled. I'm expecting that the HP Openview to discover all the devices in the network while the CiscoWorks discover all the routers in the network by looking on the routing table in RSM. At the end, it turns up that both of the network management software didn't discover any devices in the network even the after 2 days leaving it on my table to discover. Do you guys think that I should replicate/mirror all the other VLANs traffic into my network management port (SPAN)? Any idea or improvement should I look forward in case I left our any of requirements? Thanks in advance. p/s: I'll be appreciate that if you intend to asked a question, please reply to my email and I will reply to your query to the group again to illuminate unnecessary flooding.

RE: Firewall in ATM environment (design question).
Title: RE: Firewall in ATM environment (design question). Sorry for the confusion caused yesterday. Ignoring the fact of the Internet bandwidth (say E1 line), they were using the Cisco 3600 series router to connect to Internet. The reason why we put a firewall in my diagram was to maintain a secure connection between branch to branch, LAN to LAN and branch/LAN to Internet. The scenario such as Remote Network A (ATM connection to the core ATM switch) will need a secure connection either inbound or outbound traffic. Others such as LAN A or B might prohibit from any other source to came into their network. What I had in mind or option I could drafted out are like below: a) Implement a L3 catalyst switch to connect Remote LAN A & B via a VLAN to the Internet and filter any incoming traffic from other source other than from the Internet router. b) Use e-LANE (I'm a bit confuse with this, but it's an opinion from friends).

Traffic Director with LanProbe.
Hi, Does anyone have experience configuring the HP LanProbe III (RMON 1) with Traffic director 8.1? I had install the lanprobe with an IP and as an agent. When I test the probe, it returns the following string. General info: IP Address: 10.1.5.106 Ping: Not supported Read Community: "public" OK Write Community: "public" OK SNMPv1 Protocol: Supported Protocol Monitoring: Disabled or Not Supported Application Monitoring: Disabled or Not Supported High-Capacity Monitoring: Disabled or Not Supported Application Response time: Disabled or Not Supported Resource Monitoring: Disabled or Not Supported Interface info: Interface Number: 1 Description: HP LP-III Intel 82596 Interface type: ethernet csmacd (6) Physical Address: xx-xx-xx-xx-xx-xx Number of Interface: 2 Net Speed: 10 Mbit/sec What I observe from this string is that I will not be able to perform traffic monitoring or even segment zoom into the lan probe because it says "Error Accessing Agent Rmon-agent1(10M)! While retrieving ETSTATS. Error: Entry or Group not present in Agent". The group of agent and the agent itself is configured properly. Even with the new HP LanProbe (RMON 2) doesn't help either.

Configuring ELAN with VLAN. [7:5367]
Cat5505 with LANE module (A & B PHY), 1 x 24 port module, 2 x 12 port module, SUP II. There's a Hitachi ATM switch pre-configured with 3 ELAN (eg: demo1, demo2, demo3) with only 1 ATM server address given which we can't play around with. My attempt: a) Configure 3 VLAN (10.1.1.1, 10.1.2.1, 10.1.3.1) in Cat5505 with 1 VTP domain (transparent). Then assign VLAN 1 to 3/1-12, VLAN 2 to 4/1-12 and VLAN 3 to 5/1-24. b) Configure 3 ELAN as assigned by the Hitachi ATM switch into Cat5505 ATM module with the server atm address. c) Create 3 database for different ELAN. d) Configure 3 sub-interface for 3 different ELAN bind to the VLAN number Result: 'show lane' no global LECS addresses exist cumulative total number of unrecognized packets received so far: 0 cumulative total number of config requests received so far: 0 cumulative total number of config failures so far: 0 Question: When I attach physically a laptop to VLAN 2 and assign an IP to it as 10.1.2.10, it could not ping to another destination behind the Hitachi switch. Thought the ELAN (when bind to VLAN2) would forward the udp traffic to another switch. Your comments is highly appreciated.

Fail over to 2 ISDN Provider. [7:9899]
Hi, Out of curiousity, one of my respective pre-sales ask me this set of question and it triggers my mind whether this is feasible to implement. Assuming there is only 1 router with 1 ISDN card (regardless what IOS/Model it is), where 2 Dialer profile is configured for 2 separate ISP. The scenario is if the first dialer profile fail to authenticate/connect due to some other reason, how could I tell the second dialer profile for activation? Each and every IP is dynamically obtain so there is no way of using metric or static route to do it. But what abou backup interface? I'm sure this might squeeze our mind a bit, while I'm still wondering around cisco website.

Spanning tree cost for redundant connection. [7:11623]
Hi, I have about 18 C3548 switches with UTP cross-over as a redundant link to the core C6009 switches (1 unit) and the production link of LX & SX GBIC. When the production link is in operation, all the GBIC ports is in forwarding state. However when I attach the redundant UTP cable at 1 C3548 to the another C3548 (cascade), I wonder why they are still in forwarding state. Here's a basic layout. C3548\ /C3548 (utp) |\ /| (utp) C3548 C6009 - C3548 (utp) |/ \| (utp) C3548 / \C3548 How do I set the cascading port (as a redundant link) into blocking state?

RE: Spanning tree cost for redundant connection. [7:11623]
Can we conclude that whenever each UTP resilient link is in forwarding state, only 1 link is in blocking and the rest in forwarding state as shown in the diagram early? If this is normal, I shall leave it as it is. :) Regards, Ryan -Original Message- From: Michael L.

First learning experience. [7:27652]
Hi all, Just want to tell you all that I finally attempted my first lab on 28/11. What an experience for 2 years in networking line (newbies) after completing all my NA/NP certification and finally now turning to the lab. I knew I didn't do a good job there though the result have not been released yet (which took a couple of days), it's my first learning experience. I found that this is the complete lab I'd ever put my hands on, all the while I only had 4-5 routers at home to practice. Lots of practice needed to get me more prepare for the next round, which might be 1/2 years ahead. I was inspired by Chuck's story line before I had my exam the other night, and now it's all over. Time is not something we ask for, knowledge keep you going. You got to know what to do when you face a problem, you don't really have a choice. For the last 15 mins before it's over, I knew I will not finish them on time so I'll just stop and review all the question and keep them in mind. They are my first lesson and it'll be more tougher the next attempt. I didn't regret for the result later, I'm just happy that quality of the exam really worth for everyone here to work after. They'll sure pay off one day. One day lab is a monster, with little trouble in mind memorizing the ip address, distribution and routing table, you will soon overcome them. Once the frame relay works, routing come into picture. You have no idea how and what the end of this lab are trying to achieve, putting tons of assumption into the answer though they never work.. you got no time to browse the documentation cd, you can't wait a sec to save your configuration and you can't affort to show run your configuration at all time. Memorizing and organizing every single information is crucial to keep you on time. Luckily troubleshooting is removed from the lab. Thanks to Jeff for putting off my nervous on my first attempt, I'm sure I'll see you again next round. On my way home riding on a bus, the question still dazzle on my mind. The movie played on the journey home, Pearl Harbour even inspire me that getting train to fly a dangerous mission even harder getting the CCIE status. I promise myself that I'll work even harder for my next lab attempt. To all the others coming up with your lab attempt this year, good luck to you all. Never doubt on your first attempt, take it as part of your first learning experience. My mind is empty when I had it also. Have a nice day.

Design opinion. [7:23335]
Hi! I have the following scenario with regards to the design of 2 sites connected via dishes as a backup. The satellite dish is connected to the router's Ethernet port so when one of the ISP A/B is down, the whole site will fail over to the other site via satellite link. Here's the diagram for your reference. Site A /-- LAN Firewall -- DMZ / 2621 --- ISP A (assume 192.168.1.x/24) | | | 10Mbps backup satellite link | | Cat2900 (LAN) \ Firewall (192.168.1.100/24) | \--DMZ | 2621 --- ISP B (assume 10.1.1.x/24) Site B Question: a) I would forsee that there will be some routing issues here. Since the satellite is not connected directly to the router, there is no way the router will be able to fail over gracefully. The only option we have is floating static route (ie. route 0.0.0.0/0 192.168.1.1 0 & route 0.0.0.0/0 192.168.1.100 200) hoping if the first route is unreachable, the route will revert to second higher route metric. Will this work? b) The DMZ at site A will not be able to fail over, since no inbound traffic could come in hence (in this scenario, we are talking about a mail server) I intend to put 2 different IP in the InterNIC DNS. 1 point to Site A and 1 to Site B. Question is how the traffic could route back from Site B firewall to Site A DMZ? Unless we mirrored the mail server to both site so the mail to Site A will be stored at the mirrored server at Site B. c) What about the client at Site A going out to Internet (via ISP B if ISP A is down)? The firewall will perform NAT at Site A, then router will chose to route to Site B's firewall and NAT again out to ISP B. It seems very complex to me. Any alternative? Any input or criticism is welcome. Thank you.

What steps to take under *any* attack? [7:23336]
Hi! I have a couple of question with regards to the security attack (for beginners like me!), if you suspect this will happen to you. Say you have a PIX with cisco router, your inbound traffic is very high and the PIX logs is filling up with lots of port scanning, connection drop, DoS attack, nimda and etc.. what would you do at first place? Any steps or procedure people practices? As for my suggestion, if the logs show http attack (base on the destination port), I will intend to debug ip http traffic in the router, then probably ip icmp traffic. If by most of the traffic is inbound, I would immediately apply the access-list to filter all the inbound http traffic. Any suggestion?

Summarizing OSPF to IGRP in lab. [7:23835]
Hi! I guess this question might shoot up several times, but I'm trying my luck here if someone could point/reforward back the similar question earlier. My question scenario is summarizing and redistributing OSPF /25 or above mask into IGRP route. As we can see here, the IGRP might advertise and accept any mask below /24 while my OSPF redistribute and summarize the /28 mask into /24 mask for IGRP. In this case, we have 2 route with /24 mask to the same destination, isn't that inefficient (at least that's what the proctor thing)? Or the administrative distance is taking up the role here?

No matter what I did, I would get errors stating I had a mismatched authentication key. Well, the key was "cisco" so that's not too hard to type in correctly. Still, I played with the configs on the two relevant routers and I rebooted them several times, all to no avail. I even changed the authentication type to md5 and got the same message. Very weird. I thought at one point this was an IOS issue because one router was running 11.2(7) and the other 11.2(25a). I upgraded the first one to 11.2(25a) and I still see the same error. I peeked at the solution and saw that I had it configured exactly how they suggested. Then I checked CCO and saw that they suggest the same configuration. Do any of you have any tips for configuring virtual link authentication? This seems to be a pretty simple config and I don't see what I'm missing.

The company I work for is a cisco premium partner. As I have understood it to keep the partner status the company will have to specialize (take a couple of online courses and a test) to keep the partnerstatus. So we choose wireless specialization.. My question is if anyone has taken the test yet, and if so.. how was it compared to the online courses? best regards Johan Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=23972&t=23890 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
