Cisco :: Topology Services LMS 4.2.2 Links Showing As Ethernet Channels?
Oct 15, 2012
im trying to figure out the right way of configuring cdp on devices so that they dont show the links as etherchannels segments linked together, i have several port-channels in the network and the layer 2 view seems all messy.

The regular problem with the LMS topology and WAN Links when you see the branches are disconnected from the HQ BUT in my case the branches are already connected via Layer2 links but unfortunately some intermediate layer2 modem/switch exist in some branches which prevent CDP discovery but you will find both HQ and branch router in the same subnet .

current topology is build from 4 6500 switches connected in a ring topology. Using Port channel (2x 10Gbit) links to connect left side top and bottom 6500's (DC1), 10 G bit link to connect right side 6500's (DC2) In between a 1 G bit link is used to connect top 6500's (DC1-DC2) and the same for bottom 6500's (DC1-DC2).
Path costs are 5 and 6 so the T5/4 from bottom right is blocking. Bandwidth demands are increasing, so thinking about adding extra 1 G bit links to the existing ones and create ether channels. Path costs here are 4 and 5, so T5/4 from bottom right is still blocking, but when the bottom 2 G bit port-channel is loosing one 1 G bit link the path costs of both directions become equal. So I am worried that STP will not re converge and leave me with a congested 1 G bit link. I cannot test this setup in a lab, are there any options for STP to re-converge here?

I work with the topology view in LMS 4.1. I can see all the links between the differrent switches (N7K, 3750, 3040).I miss only the links between the different N7K's. This links have one special thinks: they are configured as " rate-mode dedicated force" In the N7K cli this interfaces are displayed with the SN too.
sw-bb13# show cdp ne.The links to sw-bb11 and sw-bb21 are not painted in the topoloyview.

Using Topology I can show device view from all my managed VTP domains. I don't understand why all links are "not in network"!?

On a LMS 4.0.1 :I want to know what is the right way to change the telnet program on the campus mgr map (topology services map), when right-clicking a device icon and selecting telnet.I would like to use a tool of mine, and not to launch a telnet command from the IE browser.I changed the default telnet of Windows in the registry, but the program is still launched as a telnet URL in the browser and this is not what I would like to do.

We have a problem with the Layer2 view of the Topology java applet in Cisco Prime LMS 4.2.The Layer2 view shows all the ethernet interfaces links but not the ones in the serial interfaces.All devices have CDP and SNMP (read-only) enabled, and theirs neighbors can be seen with "show cdp neighbors" in both sides of those links.

Can LMS 4.0 display event directly on Topology Services when error occurs without accessing the other module by clicking right mouse on device? Anyway, I configured the logging command on all device but I cant see any syslogs on Event Monitor > Syslog. It dislays "No Syslogs are available" message.

I noticed that I cannot remotely check the Topology Services in Ciscoworks LMS 3.2. I have attached a screenshot of the error for reference. When I access Topology Services on the server itself, everything works well.

it seems that users with active device authorization - e.g. permitting only a certain user defined group - can anyway view all devices or views?Is it possible to apply the same view rule from user management, so that these users can only view certain devices or topologies?

My attempts to connect me and my girlfriend's laptops together for some LAN gaming with an ethernet cable has had some odd problems, with my LAN connection showing up as an Unidentified, Public Network which I cannot edit in any way whatsoever. I'm at a loss. I've tried setting a static IP and it didn't appear to work at all.The network bridge is to use my laptop as a wireless adaptor for my Xbox.

my new build i installed a TP-link 300mbps wireless card, it will only however be recognised as ethernet controller and not the normal network adapter. So i put an old wireless card from another PC into mine and it works without a hitch comes up with network adapter in device manager and installs fine, and the problem card was put into an older PC and worked fine just like expected. Im really unsure on what could cause this and im not to sure about buying another card just get incase
my system info is(not sure if it matters)

My Ethernet is not showing up in device manager or Network Connections. I've checked the bios and it is enabled. I've also tried to install the drivers, but at the end of the install this error message pops up " the Realtek Network Controller was not found. If Deep sleep mode is enabled please plug the cable"

have had a new HP G62-234DX laptop for about 4 months now and I'm now having problems connecting to the internet via ethernet. The lights do not come up when I plug it into the port and I have already tried to download the Ethernet driver from HP but it didn't seem to install properly, tells me it only works for Windows Vista which isn't true. I checked my device manager also and saw that I only have my wireless network adapter showing which works fine because I've been connecting wireless but I need a wired connection when I do not have wifi at my university. On device manager I chose 'show hidden devices' and I saw an unnecessary amount of "Microsoft 6to4 adapters" come up which does not seem right.

my computer is a dell dimension 1100, with a Linksys WMP54G wifi card, running vista home basic.In the wifi thing in the notification area, it shows two wireless networks, One is my normal SSID (Lower Net), and one is "Unidentified network". They are both on one wireless connection (Wireless Network Connection 3). When i try to go on the internet, it says i'm not connected. i tried disconnecting from the unidentified network, but that disconnects me from lower net too.

I am testing a Cisco 1552 and cannot seem to set it to use the 40 MHz channels. In the controller GUI is is set to use 40 MHz channels under DCA for 802.11a but when I go into the CLI and show the config of the AP it shows the channel width to be 20 MHz. If I try to change the channel width through the CLI I get "radio is not disable or ap not set to customize" or something like that. The radio is disabled globally and locally. Is there a way to set the AP or radio to a "customize" mode?
What prompted this was I was testing the throughput on it and can only get a 130 mbps data rate connection to it. The data sheet says it will support 300 mbps with the 40 mhz channel so I was trying to test it atteh higher rate.The HW is a Cisco 4402 with 7.0.230 software on it, 1552E.

I've got a deployment of 1142N APs using a pair of 5508 controllers running 7.3.101.0. We're in the United States and the country is set to "US". I've added the UNII-2 channels to Auto-RF on the controllers via "config advanced 802.11a channel add 100" and so forth. According to the output of "
show advanced 802.11a channel", I've enabled every 5 GHz channel that's legal for use in the US:
802.11a 5 GHz Auto-RF Channel List
Allowed Channel List......................... 36,40,44,48,52,56,60,64,100, 104,108,112,116,132,136,140, 149,153,157,161,165
My confusion comes because the automatic assignment of 5 GHz channels is heavily biased toward just a few of them, with most of the available space being ignored. Here are the 5 GHz channel assignments from a large, single-story building with 31 APs:
(qty 2) 36
(qty 6) 40
(qty 5) 44
[ code].....
A total of nine channels are used (two of them only once) while twelve other channels are ignored completely. Many of these APs are close enough to hear one another, so assigning seven of them to ch. 48 makes no sense.
Looking at my campus as a whole, I've got numerous APs using channels 36, 40, 44, 48, 149, 153, 157, 161, and 165. I've got at least one each using channels 52, 56, 60, 64, 112, 116, and 132. Nothing at all is on 100, 104, 108, 136, and 140. I am using 20 MHz wide channels, between, so all are independent.
Can anyone shed light on A) why my distribution is so heavily skewed toward the first nine channels, and B) how I can learn whether certain channels are being avoided due to the presence of radar, etc, on the frequency? I'd like to take full advantage of 5 GHz by having as little channel re-use as possible.

Where you get get a modern ISDN modem with at least 4 channels? I am 2 miles from Cable and .5 miles from dsl.ISDN is the only option cause I play games online. Would 256K or 128K Up and Down be enough for playing FPS games on xbox live? I cant find any ISDN modems that are new. Only used ones on ebay that I dont know would work on windows 7.

We have a Cisco 2504 controller and approximately 35 AP's. Some of the AP's are located directly above each other (on another floor). When I run a basic annalyzer, it appears that there is some adjacent AP traffic, the controller has some of the close AP's with the same channel, so there is some RF interferance. The AP's currently are all setup for "G" and majority of the AP's are 1200 series, most of them are 1242's. Should and can the AP's be set with static channels so that there is no adjacent signals? If so where in the controller can that be done?

Couple questions on setting channels on Cisco 1552s. First off almost all locations are fibered and set as RAPs. It doesn't allow me to set the channel assignment method to "global" to use DCA. It says it can't be done for a mesh backhaul AP. Is there any way around this? Next, when the channel is set to "custom" there are only 5 channels listed to choose from in the UNII-3 band. The spec sheet on the 1552 shows it supports other frequencies in the UNII-2 and UNII-2 extended range. Why can't I select those channels?

According to inSSIDer the router seems to be using two wifi channels (10+6) and inSSIDer is recommending to move to a standard channel (1,6,11).

The only thing I notice now is that channels 12 and 13 do not work properly. Setting the router to channels 12 and 13 basically sets the channel to something in the 1 - 11 range as seen by inSSIDer. This could be because the firmware I installed is the US version, which only has channels 1 - 11, but the EU version has channels 1 - 13. Normally this wouldn't be a problem but because there are a lot of wireless signals where I live, channels 1 - 11 are quite congested, so channel 13 was quite useful to me.I don't suppose anyone has a EU version of the WAG160NV2 2.00.17 firmware do they?Channels 12 and 13 worked fine with the EU version of the WAG160NV2 2.00.20 firmware but of course only at 2Mbps.

In my LAN, I have always been used an Aironet 1250 for internal use and always work fine. Now, I added a 3com AP but both AP are not correct. When I turned off the AIRONET 1250, the 3COM AP settings works fine. When both are turn on, the 3COM AP loses connectivity all the time.I have heard about the overlapping channels in 802.11b/g networks.
