Cisco :: Free Software To Create Network Topology Diagram 1231G
Apr 29, 2013
I have a problem where clients cannot roam between Cisco 1231g-e-k9 and recently installed cisco 1242g-e-k9 access points.. On looking at the CDP option on the 1231 and 1242 access points they are all aware of each other. However if I use the Network View option I see a different picture. All the 1231 access points can see each other but not see the 1242's. Network View on the1242 shows all the 1231's but none of the 1242's. The 1231 are running ver. 12.3(8)JEB and the 1242's are running ver. 12.4(21a)JA1.

I was trying to draw a diagram for my network, when the following problem occurs.When using "show cdp neighbor" command on my primary core switch i see the proper name and interface # of the attached secondary core switch. However, upon using the "show cdp neigh fa1/1 detail" command (fa1/1 is the port i get that is attached directly to the secondary core switch and is the correct int that is connected to it) i get the wrong ip!!! The ip it gives me is not that of the secondary core switch but is that of the asa firewall!! When i go on the secondary core switch and do the same thing i get the same result but it gives me the ip of the 2nd asa firewall instead.
Notes: I am logged in to the management vlan. Firewall vlan is separate as well. asa is also connected to the switches but on different ports.

After some time LMS stops to refresh network topology (not changing colors for devices which lost/found). However, if I restart topology services devices are refreshed.
Checked the processes. Everything is fine but there is a process named "1018". But I did not found any job with this number.

i create a network topology ( i attached picture) and i don't know what exactly IP addresses should be assigned to routers and switches + there should be five VLAN's created and just one vlan (vlan 2) must see others vlans (for management purposes) and others vlans should not see each other. So i need that: 1) What IP addresses should be on routers and switches 2) How to create a 5 vlans, that they should not see each other, but one should see all, for example where i have to put "tagged" ports where "untagged" or "not member" ports etc.

We currently support a third party VOIP software. Recently we have had issues with our T38 faxing to our SIP Trunk provider because our FW (sonicwall) doesn't support Nating the connection address within the SDP packet of the T.38 reinvite. This has caused us to look at alternate solutions. I have been in discussion with CISCO sales engineers and can't get a straight answer on which one of their products support this(RFC 3362, T.38 protocol used by our VOIP server)We were looking at replacing our sonicwall with an ASA but it seems it doesn't support RFC 3362 either . However, the sales engineer thinks that their regular routers will. So If I purchase a cisco router, i.e 8xx or 2621XM the question is where do I put it in my current topograpy. Currently we our at a Datacenter and our drop into our cabinet comes right into the Sonicwall and we have all NAT handled there, routing to different LAN ports on the Sonicwall. On LAN side all we have are standard switches supporting all of our Servers.
If I buy a Cisco router to handle my NAT issue for faxing.Do I put it on the WAN or LAN side of my FW?Do I setup the router to handle all of my NATing or just the NATing of my VOIP server that is having issues with the T.38? Would I need a Sonicwall FW if I purchased a CISCO 891?

As we know when multiple PCs share same link"line" they will need multiple access protocol like CSMA/CD to protected from collision,,share link like "bus topology" need multiple access protocol "CSMA/CD" but in star topology"switch not hub" PC0 connect to port0 ,,PC1 connect to port1 PCn connect to portn then every PC connect to separate port ,, and the switch mange the network"by using MAC" then why we need to used CSMA/CD in star topology"switch"???

I am a beginner, and my customer complaining about the internet connection performance which is very slow, the network description is given below:
Description:
The building has four floors and each floor has one mount rack which contains one 26 port switch + 16 port switch. and each floor has 32 pc as well.
- 4, Cisco SR2024 un managed switches.
- 4, Cisco SR2016 un managed switches.
- 1, Cisco access point for internet connection.
- 1, Active directory server.
- 1, Mail Server.
- Internet ADSL connection, 1 MB speed.
This is the current topology.
*Note:The links and cable type "100BASE-TX under Cat 5" among all switches.
*Note:Whenever I connect to the main router "Access point" the internet becomes very fast.

I have just moved into a new office and I have free internet, but I would like to set-up my network multi function printer in the same office.I don't have a router in my office I just have the socket (presumably from the building owners cabinet). Adding another network card.I tried removing the internet cable from my PC and setting up the printer by creating a TCP port but it didn't work. (I used to do this with my HP 1050tn).RouterI tried adding a router but that didn't work either.

I would like to set up a free wireless network in our local church hall for the local teenagers to use on the way home from school.We have an ADSL router and an office computer that we would need to keep secure.Obviously we'll need a wireless hub, but keeping the public wireless separate from the Ethernet connected PC is essential.

I am on the lookout for free dynamic DNS for top level domain name such as example.com
There seem to be quite a few free dynamic DNS providers for third level domain but I am having trouble finding one for top level domain. I am almost on the verge of actually mapping the top level domain to a CNAME of a third level domain with dynamic DNS but I really don't want to do that.

my customer has FreeRadius, and I'm trying to get the server to assign a network admin role to a 5K running 5.0.3 code.This is based on the example given in this document: url...The server authenticates the user name, but will only put the user into the network operator role. This is confirmed by checking the output of show user-account and debug security user-db.The Radius test using the same credentials passes the authentication test. I'm sure the problem is that the N5K dosent understand the VSA format of the attribute, and that this is a simple syntax problem.

I own a Dell XPS M1330 laptop (Windows 7 Home Premium 32 bit, service pack 1) that is about three and a half years old. I realize this Dell model has been discontinued. Work with me here. I STRONGLY believe after 6+ hours of personal troubleshooting that the laptop model is NOT the problem. I have lived at the same apartment complex the entire time I have owned this laptop. Up until a month ago when a new management company (the third one I’ve had) took over, I was able to use the free WiFi they offer at the office and the laundry room without one single speck of a problem weekly for YEARS. Suddenly I am getting: Unidentified Network: No Internet Connection with a public park bench (which it is a public network, I suppose) and a “!” over my perfect five bar signal. Therefore, we can rule out signal strength as the problem. I have a Dell Wireless 1395 WLAN Mino-Card, the card that came pre-installed with the laptop when I bought it brand new. Also, I know the Dell Wireless Card WLAN Utility is installed on this computer but I’ve always used Windows Network and Sharing Center to control the WiFi network I am connected to. I saw something somewhere about this maybe being the problem but since I’ve never used it I don’t think it has anything to do with my problem…
Talk about the router will be brief as it is my apartment complex they will not allow me access to the router so I know virtually nothing other than it is a Cisco wireless router, there are three office computers connected to it that run the internet just fine, and DCHP is enabled on both my laptop and the router (I may or may not have snuck in against their wishes to figure this one out…).
Also noteworthy are two things. One: I can connect to about a dozen other public WiFi networks around the city malls, coffee shops, bookstores, the college campuses, ECT. So connecting to WiFi is not the problem, this WiFi network specifically is (AKA. My NIC is NOT dead). I can also connect to my boyfriend’s private network at his house. The second thing worth noting is that once, I got the manager to cave and re-set the router for me. It connected! I re-started my computer and it still connected! I took my laptop back to my apartment, brought it back re-booted an hour late and it still connected! The next morning; back to the same old annoying problem. I asked him if they did ANYTHING with the computers at night and he said no.
As I stated, I have 6+ hours of troubleshooting pre-done on this problem. I have tried what I am able to with no access to the router (okay, maybe I snuck in and did a couple more things…) including:
Re-start laptop.
Re-start router.
Disable all firewalls/virus protection programs/ect.
Connect to the internet in Safe Mode.
Disable Bonjour.
Uninstall wireless card/re-install wireless card/un-install drivers/re-install drivers/update drivers.
Reset the TCP/IP stack.
[code].....

I have a couple of questions: I have a 161 AP,s most of which are AIR-LAP 1231G-A-K9 two 4400 WLC. Some of these APs are using AIR-ANT 1728 (2.4 GHz omidirectional 5.2 dBi) and Mobile Mark OD9-240 (2-GHz omnidirectional 9 dBi) on the same access points. Some of my AP are PoE and some are using a power supply (at the AP) some are using both. Power level is set at 2 a radios are not enabled just the bg radios. I'm having issues: I need to tweak the APs (Power settings & Channel settings) so my clients (LXE VX6) can refresh faster.

I bought 3 of the Aironet 1231g access points and cannot get any clients to connect to them. I have tried everything from an Iphone, Droid2, Win 7 and XP laptops with built in wireless G cards. All say that they cannot connect to the wireless network. I have two setup currently, one on Vlan 1 that I have configured the way I want with WPA2 enterprise. The other one is just one I setup while playing around.

the firmware offers 3 different dyndns services. But opendns is not included, also there is no free field to choose protocol, server, password and network. Will this be updated in further firmwares?

I have been experiencing wireless connectivity issues with one of our Cisco 1231G AP. Every now and then users would not be able to connect to the AP. To dive deeper into this issue, I would like to configure SNMP traps on this AP. We are using PRTG and there is an option to configure SNMP trap. However, I would need to now the OID of the AP. Also i need to check for interface up/down status for both fastethernet and the radio. PRTG should be able to notify me when there is any interface resets.

I am having an issue with my Cisco 1231G access points. When I make a password change on either SSID I am broadcasting, any device I try to reconnect to the network on will not prompt for the new password. It will just say unable to connect to whatever network. The 1231G AP is using the 12.8 (8) JEA IOS version. I have had Apple, Android, and windows laptops all not ask to enter a new password. It's like the device is not recognizing that it has changed. Is this an IOS bug or a setting I have to check. I can attach a configuration if necessary.
