Hi, Sorry to make it long. We are in a progress setting up QoS on our branch LANs. In general we have a routing switch (3750 ip services) and access switches (3750 stack with ip base) connected to the routing swich using etherchannel. Routing switch is connected to the WAN CE using an access port. Routing switch does all routing and access switches are just carrying the vlans. End users (through IP phone or straigth) are connected to access switches and servers, WLC etc. are connected to routing switch. We want to do all coloring on the routing switch. WAN provider offers 4+1 clasess: real time, data1, data2, data3, BE I was trying to figure out how best the classification and marking can be done on the LAN in order to be able to pass marked all traffic to the WAN. I need some clarification on how the classification can be done best. My understanding: 1. On access switches access ports connected to IP phones: trust DSCP trust device ip phone I guess traffic sent by the PC will not be trusted or rewritten (unless I set the rewrite option). 2. On trunk ports between access and routing switch trust DSCP 3. Marking the data from all vlans Here the voice traffic (signalling and RTP) comes already marked due to trust. But what about data? Shall I set up hierarchical policy map on the SVIs? If so how to do that. I found the config guide a bit confusing with the vlan based qos. Do I need to struggle with that or is there an easier way to achieve the same? 4. WAN uplink port is an L2 port and IP address for p2p connectivity with WAN CE is on SVI. Here I need to configure the egress queuing to put the marked traffic into the correct queue. Please correct me if I'm wrong. Thanks in advance Krisztian

Hi, I'm almost clear how to configure the Wireless guest using anchor controller however I have a question. I have a centralized WLC and APs spread across locations in H-REAP mode. I have few upcoming sites requiring local WLC due to number of APs on site. I also have a guest WLAN with webauth. I planning to use the same guest WLAN (since I have centralized Internet breakout) through the central WLC using anchoring feature. So far so good (I hope). The question is whether I can use the same guest WLAN on the centralized (anchor) WLC by the foreign WLCs as well the APs already associtated to this controller? Since I need to anchor the WLAN on the central controller itself I don't know if it creates any problem for the APs associated to this controller directly. Or Is it better to setup a new WLAN for the guest WLANs being used by the foreign controllers? Thanks Krisztian

Hi, Thanks for the answer. In the mean time I have completed with the upgrade and found the following. Once I have downloaded the new code it became primary image. Actually it was not a big surprise. After I did the config boot backup. Issued the config ap image predownload primary all so the (new) primary image was downloaded to the APs as you stated. However checking the APs after predownload found that the new code became the backup image on the APs. Here I was expecting that the downloaded code will become the primary like for the WLC, but anyway... Here I was not sure whether I need to swap the image on the APs and change the boot on the WLC as well or the "reset system at yyyy-mm-dd hh-mm-ss image swap reset-aps" will do it for me? So I tried it and it was working fine. WLC has booted with new code as well the APs came back with the new code. Krisztian

Hi, Not sure what you want to achieve whether you want an outside host with ip x.x.x to appear as y.y.y.y to the inside? If so you need to configure outside NAT. Please take a look at this link: http://www.cisco.com/en/US/docs/ios/12_2/ip/configuration/guide/1cfipadr.html#wp1042290 Hope it helps, rate if does Krisztian

Hi Ven, OK thanks for the answer. However I would need sort of confirmation on the entire process . Suppose WLC1 and WLC2 are the primary and WLC3 is the backup controller for both WLC1 and WLC2. WLC3 has no APs associted with it. What I was planning: 1. Load the new code to the backup WLC3 and swap image to use the existing image (6.x) as primary and the new code (7.x) as failover. Reload controller? 2. Move the APs to backup controller WLC3 (in such a way you mentioned) and predownload backup image (7.x) (which is in fact going to be the new code eventually) 3. Upgrade the primary controller WLC1 and use the new code (7.x) as primary image. Reboot controller. WLC1 comes up with new code (7.x). 4. Swap the image on APs to use the new code (7.x) as primary and change the primary controller to the original one WLC1. Reboot APs. 5. Move APs from WLC2 to WLC3 like did for WLC1. APs and WLC3 still runs old code (6.x). 6. Predownload backup code to APs. 7. Do step 3. for WLC2. 8. Do step 4. for WLC2. 9. Swap image on WLC3 to use 7.x as primary and 6.x as failover. Reboot WLC3. WLC3 comes up with new code. 10. Relax have some beer and enjoy Is the above described the correct way? Thanks, Krisztian

Hi, Concerning the upgrade process as per the documentation before upgrade the WLANs and 802.11 networks have to be disabled. If I do that will the APs move to the backup controller or before dissabling everything I need to move the APs manually to the backup controller. Thanks, Krisztian

Hi, Seems to be shorter indeed but... To move the APs from one controller to another I need to reconfigure them with a new primary controller and reboot them right? Just some clarfication needed on the steps: 1. Does WLC3 run the new code here after upgraded? If so when moving APs from WLC1 APs start downloading new code. 2. If WLC3 runs on new code first I have to predownload the new code to the APs and reconfigure with new primary controller and reboot right? 3. I guess here the only the code is already on the controller and just need to swap the primary and secondary and reload. 4. Again APs need to be reconfigured and reloaded to push them back to original (WLC1) controller. Thanks, Krisztian

Hi, I had the same dillema i.e where to deploy WLC for a corporate having multiple sites. What I can tell you consider the following: If most of the traffic should be kept local to the site you can use H-REAP mode though if you have more than 3 APs per site (and most probably you have) then it is not recommended/supported by Cisco. So if your wireless traffic is mostly towards applications hosted at for instance in a DC then you can go ahead with centralized WLC assuming you have sufficient WAN bandwidth. If your wifi traffic mostly toward local file servers for instance better to use H-REAP (less than 3 APs per site) or use local WLC. Another thing is I was told that AP to WLC control traffic consumes roughly 128kbps per AP. I don't know if it is correct but better to calculate with. So be carefull with centralized deployment. So I would say your design fits the requirements and also inline with recommendations. The gues traffic can be tunneled back to the central controller if you have centralized Internet breakout (auto-anchor). You may take a look to this link: http://www.cisco.com/en/US/prod/collateral/wireless/ps5679/ps5861/prod_white_paper0900aecd804f1a23_ns337_Networking_Solutions_White_Paper.html Hope this help rate if does, Krisztian

Yeah, that's the curse of low end switches. If something is cheap then you have to live with all these kind of issues. Not like higher end products wouldn't have nice bugs. I'm hesitating to offer this model for our client, but if it is not resolved asap I need to find another product/vendor. Actually it is a shame how a software release can be released with such a major bug.

Hi Scott, Just one more question. I cannot find anywhere the 3500i antenna paramaters (range, gain etc.) I was searching Cisco as well but without success. May be I'm just blind Do you know it by any chance. Thanks, Krisztian

Hi Scott, Thanks for the answers. That's what I was afraid of. So the 3500 is not supported at all with code 6.0 but only with 7.0? Krisztian
