I have configured a GRE tunnel and set the IP MTU to 1420 then I received this message. %Warning: MTU set 1420 is greater than default 1396, fragments will happen, What and where is this default MTU? Ive never set one and it doesnt look like any values Ive encountered for the MTU before. (its an 1841) Even a link to a document would be fantastic here as I cant find any info so far.

It only happens with 1of my laptops, all others have not problems. In the network and sharing ctr, it intermittently says Access type: internet then suddenly I get a no internet access. I've tried release renew DNS, reboot computer, release/renew IP. When it says I have internet access, I attempt to connect to no avail.

View 6 Replies View RelatedI am getting the below error on my new switch though I can’t find out A. why I am getting the error and obviously B. how to resolve said error as I need to ensure I am operating under the letter of the law and compliance. The switch is a WS-C3750X-48T-S running C3750E-IPBASEK9-M, per my research IP base is the correct IOS for a T-S switch, the label on the outside of the switch matches the show ver (WS-C3750X-48T-S) so I know that IPBase is the right IOS for the hardware. Could it be that I don’t have the license file installed? Below is what I get when I do a show license. Lastly is there a place that I can find what IOS ships default with what switches, not version but type like c3750e-ipbasek9-mz.150-1.SE vs c3750e-ipbase-mz.150-1.SE

One of our clients is replacing some of their aging network components with 4 Cisco 2960S switches. Unfortunately in this case, my skills of switch configuration are greater than my skills of network design. I have a really crude network diagram of their basic network layout (4 servers, 4 switches, and a number of endpoints).
How would you experts design the physical connections in such a way as to facilitate some redundancy?
Is there much of a network speed difference between a green drive, Seagate Barracuda or a regular drive?i.e. would you see greater network throughput with a 7200 RPM drive compared to a 5900 RPM drive?
View 6 Replies View RelatedWhen we install an HWIC-2FE card in slot 0 or slot 1 of a 3845, the interface fails to pass any ping packet greater in size than 449 bytes. It works fine up until that limit is reached, but then fails completely on a larger size packet. If we move to slot 3 or slot 4 on the 3845, the card works just fine! I have looked through the cisco official bug tracker for HWIC-2FE, but could not find a similar symptom listed. We're running advanced ip services 12.4(24)T7 code on the routers. Any software fix or if this is a platform problem with the 3800 series.

I went to the Dell Drivers and Downloads site in order to get a driver for my bluetooth. The driver I found was C:DELLDRIVERSR140135, I checked the compatibility and it is supposed to be compatible with my system and Windows Vista 32 bit. However, whenever I try to install it, a window pops up instructing me to push Fn+F2 or the Radio on/off switch. Fn+F2 does not work and there is no radio switch. I tried to start over from the beginning, now it's telling my I need Windows Vista to install this driver ... I am using Windows Vista. I checked the Device Manager ... no exlamation points or question marks.

I now have two identically configured (same hardware and software) Inspiron 1420 (new) and I can't get the Wireless Activity Indicator light to come on. I've talked with Tech Support three times (Level 1 and 2). They thought it was the switch ans sent an in-home technician to replace the bottom casing of my first unit. When the Technician realized that the switch was fine and the indicator (LED light) was not coming on, I requested a new replacement unit. The second unit arrived with the same non-functioning LED. As I mentioned in a previous post, I've gone to Staples office supply store that now sells Dell 1521 & 1721 laptops and both store display model's LED activity indicator lights up when both units are off and the switch is pushed to the ">>" position. Having already insured (with Tech Support walking me through it) that Quickset as well as the BIOS have the Wi Fi Catcher enabled and Wireless settings enabled. There are no problems connecting to wireless networks when the laptop is on and the switch does turn wireless On and Off. Question to all Inspiron 1420 owners, how many of you can get your wireless activity indicator to light up when your laptop is OFF? If enough owners respond that their LED indicators don't work, maybe we can get Dell to admit a design defect. At this point, I don't know what else to do to get Dell to fix this issue and I assume they won't keep sending me new replacement laptops until I find one whose LED works.

View 7 Replies View RelatedWe have a network consisting of a central site and a few remote offices. The sites are all connected via MPLS and also have VPNs over ADSL / internet connections as a backup. The remote offices have Cisco 837 routers for the ADSL connections which we can manage but the MPLS routers are managed by the service provider providing the MPLS connections. At the central site we have a Cisco 891 for the the MPLS connection (which we manage) and a Cisco ASA5505 for the backup VPNs.
In order to implement failover from MPLS to VPN in the event of any MPLS line going down I have tried to use ip sla monitors and tracked objects on the 891 as per Cisco's documentation. The problem that I am finding is that I can't set the number of ICMP echo failures required before the tracked route is dropped. Whenever the ip sla monitor fails to get a response the tracked route is dropped immediately. This is too sensitive as packets are occasionally dropped which results in the routes bouncing back and forth between MPLS and VPN too frequently (disconnecting users in the process).
I have tried different threshold types and values, tried configuring ip sla monitor reaction-triggers (although I don't understand what little documentation that I can find on this) and have even looked at event manager. I have been working on this for a few weeks now and am getting nowhere.
The Cisco ASA5505's implementation of ip sla monitor is much better in that it is possible to specify the number of packets but unfortunately we can't use the ASA as the default gateway for the LAN as the asymmetrical routing that occurs does not work with the firewall function of the ASA.
Any issue with ip sla monitor on IOS and managed to get it working?

The catch is I cant alter the customer router only the the two ISP devices. I tried doing some route maps but I'm lost.

I'm in student halls where the internet connection they provide is via ethernet cable. I've read somewhere that if I hook up a router I should be able to set up wireless - so I got a relative's old router and hooked it up. Everything is connected and working fine, however, the connection has no security set up whatsoever.I can't connect to the default 192.168.1.1 or the 192.168.0.1 which I believe would take me to the router's settings page (according to the manual) where I could set up a WPA2 password. Also, when I checked router's IP address it actually displays as 109.175.244.193, but I can't connect to this either.My ISP is StudentCom.This is a 3Com OfficeConnect ADSL Wireless 11g Firewall Router.I'm using both a Windows 7 computer and an OSX 10.8.2 MacBook Pro.
