As you'll find, I write in outline form :) 1. For the WGB, based on my testing, if you configure it "wlccp ap username USER password PASS," it will disassociate after 30-60 seconds without an error message.
2. Modular QoS is most certainly supported on the 3560s. It's just that you cannot apply certain policies in certain directions on certain interface types. The issue is knowing how and where it can and where it cannot be applied. 3. The Cisco documentation on the management interface for the WLCs is wrong. In most cases, you want to assign a bogus VLAN as the native VLAN, and use a tagged VLAN for management. 4. Good point about the H-REAP APs and whether or not to trust CoS or DSCP. That will be completely dependent upon the requirements of the lab. 5. Good write up Darby. There are a few things I probably would not expect to see, but as you said, you never know. Even Cisco says that there may be things on the lab that are not on the blueprint :) This is the lab. It may or may not reflect real life :) Jason Boyers - CCIE #26024 (Wireless) Technical Instructor - IPexpert, Inc.

I made some notes while I was reading it through: I cant' see all you mention is on the blueprint. But the harder the training thus easier the battle! AAP WDS: bridged ? I at least know that AAP in repeater mode does not support WDS participation. Cause there are WLCCP multicast issues. I somehow gather that WGB could be a problem too. Unless it was participating over the Wired side. But do you think it works over the wifi linki ? anyone ? ntp server: I wonder if they would present a NTP it has to be time synched somewhere. It is a small worry if you need to put up a VTP server yourself and manually set the time on it. Or if there is some source that is synched that can be used in the LAB. ACS: I would like to add TACACS configuration for roles. for example admin role1=all and consultant role1=monitor schenarios. This can be done too with Radius. I would exect the authentication to be encrypted in some cases like you wonder about. and Encrypted radius key ACS vs WLC. I have done some excersices with it in the Fastlane workbook. It might say do it FIPS best practices and that is from what I read a requirement to support FIPS. QOS: modular QOS not supported on 3560 but on the CME so SRR is worth considering in 3560s. I have not seen if QOS priority is to be set somewhere. I can only see it would fit on the links between the switches. I wonder If there will be a wired phone somewhere plugged in. (the 7920 has to ring to some phone of course) SRR queues is best practice on wired phone. I am going to expect that there is one wired phone. The QOS for the 7920 could be over the lwapp tunnel so marking and trust via DSCP on the LWAP and marking and trusting COS on the WLC trunk ports would probably cover that. I don´t know if they let you prioritise after that on SRR queues after it leaves the WLC on a VLAN. But I certainly am going to master that as far as I can. QOS in cat65k: is different from 3560 so I'm deffinatelly going to investigate what one. I find it strange with Cisco documentation that the mangagement port needs a native VLAN. This means no QOS tagging on the that managment VLAN ID !! interesting, perhaps it is tagged somwhere else. H-REAP QOS port settings: This popped to my mind. As when you change an AAP to trunk VLANs you are not trusting DSCP but COS for the trunked VLANs. But what about if there are other none H-REAP VLANS going over the lwapp tunnel aswell ? interesting question. How would you set your mls qos trust in that schenario. Perhaps it is a collision and not supported ? This is just my thougts reading your great post Darby. regads.

There seems to be a general lack of direction and plan in place. There has been some activity and it has been at varying levels of expertise offered previously. The quality differs it would seem based on the background of the presenter. It's a given. We are dealing with a new track with very few role models as of yet and those that have emerged are still getting the presentation mastered, not to mention deliverables. So... we are largely left to our own devices (not meant to be a pun on words). Collectively, we have the capability to send this lab back to the its owner on its knees wimpering. Individually, I don't know I've seen 100% of what I'd expect from the various offerings I've seen so far since I decided to get a little more serious towards this tracks. Things don't quite look as complete to me. However, I have seen a wealth of offerings from Cisco and while I've yet to attach each item I've found to the actual blueprint on the lab, I can say that off the cuff it looks like it is more than has been offered commercially, however, not necessarily in one place. So it takes time to decipher. I'm using my own study methods for the CCNA-Wireless and CCNP-Wireless and so far I'm 3 of 5 exams into it. My methods are working remarkably well and better than hoped so far. I budgeted for at least one re-take per exam however so far this has not been the case. I have Security on Wednesday and CCNA-Wireless on Thurdsday. I am considering touching up and re-certifying the Cisco WLAN DE/FE/AM exams too while the iron is hot. However, that's 4 more exams with the CSE and it is a diversion from the goal. The CWTS/CWNA/CWSP are the next certs immediately on my hitlist and the CWAP/CWDP (pending a book and blueprint for the CWDP) are quickly following the first phase. All of this leads the CWNE after I perform the write-up for at least 3 of my Wireless Project, get my references (I have sufficient references from my current employer but may ask for 1-2 references from former employers/managers to spice things up a little and validate my history/projects cited and my role in them). While not directly related to the CCIE Wireless, I think the recognition of being a CCIE Wireless is enhanced by being recognized as a CWNE as well. Others opinions may and will likely differ. No doubt. No need to elaborate. As far as the CCIE Wireless Lab: 1. The physical topology appears to be set in stone with little or no permutation. 2. The logical toplogy is dictated largely by the physical topology mentioned in number 1, however there is still a little wiggle room for a proctor's delight. 3. The sections of the lab are clearly defined. This appears to be case with the lab itself and I'm to understand they are represented quite well. 4. We can count on the following: - 6500 with WiSM, there may be two for redundancy and that's fine. But it does mean 4 Controllers and this is even more reason to leverage the usage of the WCS. - The Spanning-Tree can largely be anticipated, the spanning-tree protocol can be varied but this is of little consequence to the overall exam. I'd plan for Rapid Spanning-Tree but not surprised if asked to configure MST. All Spanning-tree features would be a given. - Port Channels - no doubt in my mind. Load balancing and optimization are highly likely. - VTP and Pruning - Always a CCIE Lab traditional favorite, it's kinda like vanilla ice cream... it never runs out. - Odds, Evens, Timers, and we can count on all of these features. - H-REAP and apparently with a 7921. This means EAP and likely EAP-FAST but I'd not discount other EAP methods, You know ACS configuration is going to be required well. Small matter. We could be asked to migrate the AP from AAP to LAP or doubtful but backwards. - AAP to LAP - I expect this to be required mostly everywhere on the 1242s and 1252s except for the 2 APs where WDS will be asked for. - WDS - you know it is there so expect it. I'd further expect it to be bridged. I'd expect multiple VLANs/SSIDs as well. Call me crazy, but it makes sense to me. - DMZ Controller - Yep - From what I've seen it does not look like the CCIE Wireless candidate needs to worry with the Firewall but that does not dicount either an ACL for the ports and protocol or whether QoS (probably necessitated by best practice requirement) will be the whim of the day of the lab. In any event, we get tested on a variety of items here, namely: Internal Controller DHCP, Authentication Methods, Wired and Wireless Guest VLANs with or without DHCP, Lobby Admin comes to mind, Authentication for Splash Page, maybe a little quarantine, etc. - WIPs seems like this may not "be in the lab" itself as the IDS is not a lab device on the blueprint, but that never stopped Cisco from saying it could be there and to configure for one before. - Management - Lots of interfaces, lots of VLAN interfaces, Native VLAN, SSID/WLAN to Interface Mapping (one click and you lose points fast) to VLANs, to HSRP with Etherchannels, etc. - Span/RSPAN and maybe ERSPAN? Now add the extra AP Roles to the mix. This can get interesting but given the finite number of APs, I'd bet for configure ad-if a Sniffer AP were used and I'd gues one of the 4 1252s is either a monitor or a Rogue to be detected by the WCS or Location appliance. - WCS - I see a lot of tasks here - management for one, alerts and logging for another, it's got to sync on time too, maybe produce a survey/heat maps, etc. Lots of fun here. How many points is it worth? Templates galore. Reports. Lots of tasks. Time-muncher too. - ACS - Well everyone has roles to configure, maybe users, maybe quarantine vlans or downloadable acls - AAA overridde is an interesting feature. VSA's can be intersting and the blueprint nailed a nice little must-know list. Other tasks might be asked related to the maintenance of the ACS itself. I do the CA/PKI being a particular task. - EAP and RF - Yep - I'd fully expect every type of EAP to be asked and required - kinda like the spanning-tree tasks. - DHCP on the routers, switches, MS, and internal as I mentioned before - Internal will surely be required in the DMZ. I'd expect the router to handle DHCP for the H-REAP AP, and I'd expect MS for the other vlans - Global versus Local option and DHCP Authorization are fun little gotchas. Static MACs can be fun. - Port-Security is another decent task to be presented with. - DAI/IP Source Guard/DHCP Snooping - Why not? Quick task that drains minutes and is probably worth 2-3 points collectively. - QoS - Interesting, I've seen it worded to represent "Best Practices" and so now we are tasked to understand best practices and implement them. Where is CoS and where is DSCP. Are SRR-queues best practice? What about Priority Queues or Ingress versus Egress Queues, Mutation Maps are fun too. Policed DSCP is probably a task and rate limiting is easily tied to it. MQC on the routers... inbound versus outbound maybe (why or why not)? - WMM and the VoWLAN - Hmm.. Upstream versus Downstream. 802.1p. - 802.1x - Encrypted RADIUS anyone? - Modifying any policy on the WLC just because you can. - Crash dumps on anything? - Autoinstall is an old time favorite especially for AAPs. - NTP is not just on a WLC/WCS, but also in the network and it has to work. Always fun. - Banners/Hostnames/SSH/Syslog/SNMP (what version?). Remember some of these appear trivial on the Gui, but might need a little trial and error on the IOS of the routers and switches. - Switch Port Trace - Wired Guest Access Hmm... just thinking out loud. I'm sure I left off 50% of the test but this is off the top of my head. I guess I need to take the blueprint and match it up with what I expect to see on the lab, time myself for performing a given set of tasks. I know a lot may frown on the older controllers but they are cheaper than the newer controllers and they do mostly everything I've listed so far, with few exceptions. To each his/her own. Ok It's past 2am and I'm in class this week. Any thoughts? Do I read too much into this or not enough? I know I left out a lot of stuff but it's late and I was just kinding of making a mental checklist and thinking about the order to perform the tasks in question. - Core - H-REAP - 1252 Cluster for triangulation and Context-Aware/Location - Switch Port Trace needs a rogue and a rogue client to work - Mobility Groups - met by the WiSM - DMZ - Anchor and Foreign Controller - CA/PKI - Enterprise QoS (E2E) - WCS/Location I mean so much of this test seems like a given, looks like a race to the finish line - lots of tasks and lots of room to fat-finger just about anything. Verification is key of course and do lots of debug tools might be nice to know about. I see a lot of areas with room for interpretation and I see a lot of this lab that might every well be seemingly related to other tracks. Particularly switching - I can see a lot of points on the various switches and who always considering the Egress Queue on the 6500 modules anyway? Call for conversation at least. Tell me where I'm so far off-base it's not even funny?
