I wonder if I can build a NTP Stratum 0 device using a GPS and a Cisco router.Preferred would be a CISCO819 as it has a build in GPS, alternative a CISCO2901 + EHWIC-3G-HSPA+7.

I am now having trouble to buil a vpn ipsec on an adsl link, my architecture is as follow:
[code]...
whith this output, debbuging seems very difficult. see attached my configuration on router 1841
Any configuration example to build a vpc b/w 5ks and 7ks? i have total 4 links between them . If not, I am assuming to have the following config for the port-channels:- (Provided the vpc domain is configured).
N5k1 and 2:
int eth1/10-11
channel-group 10 mode active
switchport mode trunk
int po10
switchport mode trunk
switchport trunk allowed vlan a-d

So, its basically vpc 10 that has 4 physical links b/w the vpc domain of 7ks and vpc domain of 5ks.

View 7 Replies View Relatedsetting up a single home network in my apartment that will be able to connect to and use 2 separate wifi internet connections to provide stability and reliable bandwidth for a home network.
Situation: I have recently moved into an apartment complex that has 2 separate wifi connections that are available to the residents free of charge. (yes i am authorized to use both) I do have the option of paying for and having my own personal DSL line installed but I would much rather use the free wifi and not have the monthly bill.
The Problem: My apartment is located far enough away from each of the routers (One wifi at each end of the building and I am in the middle) that my signal strength is poor most of the time and sometimes heavy traffic on one wifi requires that I disconnect and connect to the other. Wifi A is farther and has very low signal and low or no connectivity. Wifi B has good signal most of the time but gets very slow during peek usage times of the day.
I understand that I need one or more high gain antennas in order to receive adequate signals from either Wifi connection.
Between me and my son we have 2 laptop PCs, 1 Desktop PC, 1 network printer, 1 Xbox, 1 HDTV and my smartphone. I don't want to try to equip each device with its own high gain antenna and try to figure out which device should be connected to which Wifi depending on available signal and bandwidth. Rite now I do not have a Home network set up at all and we are only using 1 laptop and the Xbox and each is directly connected via wifi (usually to Wifi B).
If I could connect to either Wifi A or B with decent bandwidth and reliability and then be able to network or connect all my devices via wireless or wired to my own router/extender etc. I would be happy. However.. Given that I must share bandwidth with the other residents and at times one Wifi has heavy use while the other does not. I have been trying to research how to connect to both wifi signals for load balancing, reliability and hopefully greater bandwidth.
I have a ASA 5520 upon which I need to build a WebVPN for the company urls - webmail, intranet portals etc. There will be 2 groups -
a. Confidential Access - For senior management.
b. Public Access - For employee access.
RSA Token & LDAP auth would be used for access to the WebVPN. However, I am unclear on certain aspect.How do I isolate the 2 groups? I mean only Senior management should be able to view & access the first set of links while employees see and access the other set of links only.Both the groups will be available to all users loggin on to the WebVPN. Since the authentication mechanism - LDAP - is the same, anyone would be able to access the groups and in turn, urls.

View 1 Replies View RelatedI just built a new computer that will not connect to the internet, but only while using my wall port, and only this new computer, and only while connected through the router. Totally bizarre, right?I just built a new computer with a fresh install of Windows 7. I set it up directly connected to the router, where I applied all windows updates. I then moved it to where my old computer is, which uses a wall port to connect to the router in another room, where this new computer then fails to connect to the internet or to the router's setup. The new computer's Ethernet LEDs will light up, and the computer will automatically obtain an IP address, but will not connect to the internet or even the router setup.

View 3 Replies View RelatedI'm not being able to wireless distribute the office LAN int-con via recently purchased Tp-link tl-wr740n wireless n router'. Actually, I had no problems with my USR 8054 wireless router before I decided to replace the router with an 'N' one as I experienced some connection loss on my mac book pro(mac osx 10.8) thru USR 8054. The internet connection I have is from a wall socket in my office. I know the hub/router/switch or whatever behind has no DCHP activated because the device connected to that socket cannot get an IP, you must enter it manually together with gateway, DNS etc.. and the values are as
ip 10.50.31.108
subnet 255.0.0.0
gateway 10.50.31.254
Whenever I enter these on my USR's 'static IP configuration' via quick setup and plug the Ethernet cable from the wall socket to the WAN, it works and the router immediately starts to let me surf on the net wireless. However, the same procedure has never succeeded on my Tp-link with its latest original firmware or dd-wrt. It even says no cable connected although it is connect from the wall socket to its WAN.I also tried to connect my computer directly to the wall socket with a regular Ethernet cable and entered the ip, gateway etc manually. It didn't work at first, then I changed IPv6 setting from ''auto'' to ''local connection only'' and I was able connect to the internet with no trouble.
Started a upgrade of my firmware to Ver.2.0.03 (Build 10) for the E1200 H/W v2 and at 98% it stalled this was over wired connection and via http not https.
I'm really disappointed which this router because in all honesty its been one of the slowest I have ever bought whereas the Wireless-N doesn't truly work with N speeds being like 3-9Mbps where if I disable WMM and switch to B/G Only then my speeds jump to 20-30Mbps.
I am unable to connect both of my smart phones to the access point. I am using WPA2 encryption on the AP. I can connect my phones to other AP's using WPA2. I have other devices that connect to the AP except my Android phones. I would like to be able to get some debug logs except the web interface says that the logging fictions are disabled when in bridge mode. Cisco/Linksys tech support: Any troubleshooting tips other than resetting the access point and or reflashing it.
View 4 Replies View RelatedI'm looking at the possibility of purchasing a few 3750 to build a switch stack to replace my current core and access switches. I'd like for the stack to support server, SAN, and user traffic, as well as provide simple switch management, redundancy, and failover. I've also been looking at the 4500, 6500, and Nexus series switches (although the Nexus switches maybe a bit too much for my network).
My current environment consists of 3560's as the core/distribution/access switches, a mixture of Hyper-V and VMWare environments (although we're slowly migrating to Hyper-V), an HP SAN (P4500), and about 100 users. Any issues going with the 3750's or have an alternative, more efficient solution?

For some really strange reason, my web browsing has been ridiculously slow, with the words "Waiting for [website]" always showing up in the bottom corner of Chrome for a good 10-20 seconds before the website loads. This happens to every website I visit, bar Facebook (secret Facebook virus?). It's especially bad on shopping websites such as eBay, taking upwards of a minute to load pages. I have tried Internet Explorer and the same thing is happening.
My downloads, on the other hand, have been unaffected by the upgrade, with download speeds averaging 800KB/s.
If it matters, my current modem/router is a D-LINK DSL-G604T; my other devices work perfectly fine on this modem, with browsing speeds being faster on my 2G iPod Touch than my desktop computer.

the only way i can get 300mbps from this router is by having these settings, it seems the only valid settings to get 300mbps from the router are the following:
Network Mode: mixed
Channel Width: auto (20mhz or 40mhz)
Channel : 1
if i leave the channel to auto it won't show up as 300.on top of that it doesn't want to stay at 300mbps for very long, sometimes its max rate in inSSDer is only 144 or 156mbps. its the weirdest thing, i think this version of the firmware seems to forget to check for how fast its wireless transmit speed is.When it reboots it only transmits at 144 or 156mbps. i have to go in the basic wireless page and just save the settings to reset it to 300, i don't even have to change anything, it resets its max rated speed back up to 300mbps.and more importantly, are the devs aware of this problem for the e1200 v2 ?
