Cisco :: 142 AP - Clarification On WCS And WLC 7.3 Versions Compatibility
Mar 6, 2013
I have 3 WLC's currently running version 7.0.116 and a WCS on version 7.0.220. I am looking at upgrading the versions and am uncertain as to the compatibility.
1. Upgrade the WCS to 7.0.240, and upgrade the WLC's to 7.3. Resulting in my WCS just not able to manage the "new features" in the latest WLC code?
2. Upgrade the WLC's to 7.3 resulting in WCS completely unable to manage the WLC's? I am aware there is WLC 7.4 code however I've read there is an issue with 1142 AP's rebooting.

Recently I came across a wireless design whcih I ws not able to understand.The design is:
1. Two wireless LAN Controllers 5508, each with 25 AP license. AP load (5APs per Contorller) shared between the WLCs and congured with Backup Controller option.
2. The design has a Data Center Switch 3560x series, on which the two WLCs, Cisco Prime Infrastructure and Cisco MSE were connected. I've attached the design here.
3. The Data Center Switch is configured with DHCP pool for the wireless clients. The IP Address of the Data Center Switch is : 10.xx.xx.2 and Default Gateway is: 10.xx.xx.1
4. On the WLC, the Management Interface is configured with the IP Address: 10.xx.xx.21 for Controller 1 adnd 10.xx.xx.22 for Controller 2. But, their DHCP Server is configured with IP Address: 10.xx.xx.1 but not with 10.xx.xx.2 .
This means, all the DHCP requests are pointing towards the Gateway of the Data Center Switch.Is this the correct configuration?I have seen the Wireless Clients getting the IPs allocated from the DHCP Pool, even though the Management Interface's DHCP server configured with Gateway IP address 10.xx.xx.1 .
The DHCP configuration for the Data Center Switch is:
ip dhcp pool xxxxxx
network 10.164.220.0 255.255.254.0
default-router 10.164.220.1
The Management Interface configuration on the WLC is:
Interface Configuration
Interface Name................................... management
MAC Address...................................... 2c:54:2d:72:b5:40
IP Address....................................... 10.164.220.21
IP Netmask....................................... 255.255.254.0
IP Gateway....................................... 10.164.220.1
External NAT IP State............................ Disabled

Basically I need to upgrade the license for Base-AP count to add 100 more AP's however my vendor has provided hardcopy of license as below:
-LIC-CT5508-UPG
-AIR-CAS-3KC-K9
-AIR-WIPS-AP-5
-L-NCS-1.0-100-ADD
My understanding is rigister LIC-CT5508-UPG/PAK number on cisco site and get .lic file however what is the use of other PAK where do i register this files with? Moreover , we do have NCS , MSE in place which is centralised devices.

I currently have a 3560G switch running c3560-ipservicesk9-mz.122-58.SE2 I have a spare 3560 V2 switch I want to configure and have ready in case of a failure. This spare switch is running c3560-ipbasek9-mz.122-55.SE5 My plan was to pull the IOS image from the current switch and upload it to the spare that way I have an "idnetical" switch. From what I have read, there are some feature differences between "ipbase" and "ipservices". However, when I run the show license command on the production switch, I get an unrecongnized command error. So that throws into my confusion as if its running an ipservices image, shouldn't it have a license file?

we are observing the no. of conn thru asa 5580 is getting increased and one a fine day it will stop sending/receiving traffics.firewall# show conn count 1900000 in use, 2000008 most used As per the datasheet of this asa, the max conns permissible is 2 million (20 lacs). and the output shows that currently 1900000 connections are there and 2million+8 connections are most used.when i run " show local-host | include host|count/limit ", below are the outputs showing for max connections..
local host: <172.x.x.x>,
TCP flow count/limit = 35857/unlimited
TCP embryonic count to host = 25
UDP flow count/limit = 0/unlimited
local host: <DC01>, TCP flow count/limit = 306/unlimited TCP embryonic count to host = 8 UDP flow count/limit = 736807/unlimited
local host: <DC02>, TCP flow count/limit = 246/unlimited TCP embryonic count to host = 2 UDP flow count/limit = 582010/unlimited
local host: <172.y.y.y>, TCP flow count/limit = 1/unlimited TCP embryonic count to host = 0 UDP flow count/limit = 308412/unlimited
These are the top 4 connections, i wonder should we consider only the tcp flow count or udp as well ?

I have a 1905 series cisco router, when I run "sh int" command it gives me following details -
MTU 1500 bytes, BW 1544 Kbit/sec, DLY 20000 usec,
reliability 254/255, txload 7/255, rxload 151/255
Encapsulation PPP, LCP Open
Stopped: CDPCP
Open: IPCP, loopback not set
[code]....
let me know the significance of txload and rxload.This router is used for MPLS connectivity.Link is working OK..but I'm not able to understand exactly what is the above txload and rxload signify.There is also one peculiar phenomena occuring, when my reliability goes down then rxload also goes down or might be vise versa.

We want to configure the "mac-address-table synchronize" command on our 6500 series switches to ensure that the CAM tables on our DFCs are in synch with the PFC on the supervisor modules. url...it is recommended that we disable the routed MAC purging with the mac-address-table aging-time 0 routed-mac global configuration command. What is a routed mac entry? Are there any issues with running that mac aging-time command?
We also plan to run this command "mac-address-table aging-time 14400" to keep our ARP and CAM tables on the same aging time to reduce unicast flooding on our network. Can we run this command with the "routed-mac" command above?

I got a few Cisco Aironet 3602i. The minimum WLC version to support these is 7.1.91.0. I am planning to upgrade to 7.2.103.0. The minimum WCS version to support these WAP is 7.0.220.0 and the next available 7.0.230.0. Checking the release notes for both of these WCS versions, there is no mention of support for WLC versions listed above.
URL
Am I missing something here ? What versions would be required on WCS and WLC to make all the three entities (WLC, WCS, WAP) inter-operable ?

I am in the process of rebuilding our ASA 5540 pair. We are currently on 8.2 code with this set of firewalls and I was going to upgrade it to 8.4 being I have a couple of other firewalls running this code currently and am familiar with it. That said, I saw that the 9.x code is out there now. Are there any major advantages or caveats with the 9.0 code? I plan to use this firewall with SSL VPN and RSA Secure ID integration for the next 2-3 years at least. Any quick pointers on these two code versions and on upgrading to 9 or staying with 8.4 line.

Why do some versions have heatsinks and others don't? The HP branded cards EH352AA always seem to have the heatsink, but very few Intel branded cards have it. I'm talking about the single port NICs - all dual+ port cards have the heatsink.

I am configuring two 2504 controllers, which I ordered together, however they run different software versions and I don't have a contract/ login to download wlan controller software from the Cisco website. The one with the newest version runs 7.2.103.0 while the other one runs 7.0.220.0 I want to run them together in the same subnet and use them for redundancy (10 AP's will connect).
Is there a way I can download the software from the controller, just like I am able to do with an ASA firewall? Then I can upload it to the controller with the older software version.

We have 3200 logical devices configured on CiscoWorks and CiscoWorks is running very very slow. CiscoWorks installed on server with Windows Server 2003 32-bit and this version of windows it can only support RAM up to 4GB, which is already installed. In order to increase the RAM we have to upgrade the windows version as well. Which versions of Window can perform best with CiscoWorks. E.g. Windows Server 2003 with Service Pack 1 (SP1), Standard Edition 64-bit: or Windows server 2008 etc. We are currently using the LMS 3.2, RME 4.3.0, CM 5.2.1

I am working for a customer on an enterprise site containing many 6509's. We have built a test environment and upgraded a chassis from sup720 running 12.2(18)SXF15 to VS-S2T-10Gb running 12.2(50)SY on the management card. I have noticed and so has the customer that there are many commands missing or added and they want an expalnation of these. I can do some of them easily, change syntax etc but for instance it has added a table-map, 50 vlans with a large MTU and large COPP policy.
What are these ?? and also is there a quick way resource etc to find out why the commands have been added/removed, for instance-mls ip cef load-sharing full is missing--

I'm putting together a lab to start on my CCNA and I've got two 3640s and two 2620s. I want to upgrade all of the units before I start on the CCNA and I'm having trouble working out what the final rommon version is for each of the routers.My 3640's are on version "Version 11.1(20)AA2". Is this the final release ?
One of my 2620's is on "Version 12.2(10r)1" and the other is on "Version 12.2(6r)". Is "10r" the final release for the 2620 ?I've also seen a few sites mention that either version "8r" or "3r" of the 2620 rommon adds support for 32MB flash SIMMs. Is that correct ?Is there a document that describes the differences between the different releases ?

We have Internal Wireless Controllers to be set up for HA (AP SSO) and wireless traffic from Guest SSID will be terminated on a Guest Anchor Controller inside Firewall DMZ. The Internal WLC controllers are installed with software versions 7.3.101.0, and the Guest Anchor controller is installed with software version 7.2.103.0. Just wondering if the Guest Anchor controller needs an upgrade to match the software versions on the HA controllers. Also, Cisco provides a new version of code, 7.3.112.0 now. So is it recommended to install the new software version on the HA controllers as well as the Guest Anchor Controller.

I have many of these, many models and versions. I have a WRT54G v1, V1.1, V2....V8, I also have WRT54GS's WRT54GL's and others, Lots of other Linksys stuff, almost all of it in the Blue and Black boxes of varing sizes.I have a heck of a time when I reconfigure my network or the wife changes the furniture. I'd love a single document that lists the power specifications and adapter requirements for thens devices... I can't find them any where on the Linksys site. I Have looked and searched and nowhere can I find a consolidate list.
Any have a list of the DC power Specifications, Barrel sizes, and other stuff needed to buy a replacement Power adapter. This page url...lists a lot of information but does not list this critical information... I am amazed that Linksys does not have it listed some where here. Losing a wall wart should not be a reason to pull you hair out, just a simple purchase, If they don't want to stock them, then at least tell us what they are.

I have a problem with current (1.0.06) firmware on WRT120N. Few hours after restart DHCP server stops assigning IP addresses. Another restart resolves problem, but only for next few hours.Computers and other devices "see" my wireless network and they are able to connect to it, but the process stops at requesting IP number.There was no such effect with original firmware (although there was another problem with 2200BG), so I want to downgrade.where can I find previous versions of WRT120N firmware?

I am trying to build a site-to-site VPN between cisco 1811W at a main office and SRP541W at a remote office.
I already have the configuration for the 1811W through SMD, but can't install the SDM on the SRP541W.
Does the SRP541 is compatible with SDM; and if not is there any other GUI to configure a VPN tunnel on SRP541.
