I'm just wondering if there is any documentation that confirms if the 2 built-in Gigabit ports on a Cisco 2851 router support (or otherwise) auto-mdix.I can find information for the modules but not the 2 built-in ports.

Cisco Router 2851 connected with one ISP using 2 serials. the case is :
1)s0/0/1.1 is the only utilized and s0/0/0.1 utilization is zero. 2)when shutting down s0/0/1.1 : the other ,not utalized, link work perfect and forward all the traffic.
Attached the configuration file with output of show interfaces command.
I am trying to set up a guest SSID which will be separate from other corp SSIDs. I have read about this auto-anchor feature and I have a basic idea. Here are some questions about the network design
1. Can Cisco 5508 with 7.2.111.3 code do NAT? I mean can I use the anchor controller also as a gateway to Internet or do I need another device such as FW or router to do the job?
2. I want the guests to get IP address in 192.168.0.0/24 range. On the anchor controller I will need an interface in this range, correct? However on the internal controller I won't need this interface. The guest ssid will be associated with the management interface on the internal controller, correct?
3. I want the guests to get IP address from general DHCP server. Does DHCP request have to come out of the new interface in the 192.168.0.0/24 range? However this interface will be connecting with the FW. It won't have connection back to the internal network to reach the DHCP server. The management interface will have the route to the DHCP server. Is it possible to use management interface for this SSID but still let traffic to pass through the Guest interface?

I am using a 2851 router in mpls network. We had a power shut down activity recently and post to that i could not find any logs in the router.
View 4 Replies View RelatedI recently obtained a 2851 and have been battling this issue for a week now. An odd set of circumstances happen with the bootstrap startup process. If the router has loss of power or when reloaded; it fails to read the CF card and boots to rommon. I can tftp an image to it (tftpdnld -r) and IOS CAN read the flash card along with any saved configuration.In fact once in IOS, I can wr mem and print the hardware details of the CF card. Once I reload the router it goes to rommon, fails to open the flash, then sits until i tftp the image back. When the router load IOS, it also loads the startup config.I don't think it's a problem with the CF card as IOS can read it. I've tried formatting the card from IOS and from my pc as FAT, FAT16, FAT32, and NTFS - it didn't make a different. I updated the ROMMON to allow for USB booting but haven't purchased a USB Drive yet for testing. The upgrade didn't resolve this issue either. It almost seems like a firmware problem with the EPROM.

Network newbie here asking an embarrassing question on logging We have a Cisco router with the following IOS version. I want to enable logging; so do I need to configure event-log enable before adding the following logging configuration?

View 9 Replies View RelatedI have a 7604 Edge router that connects to our Data centre via Fiber.
but i keep getting input errors on the interface Gi3/5. i also found out that i cannot change the duplex settings on the edge router to auto, i only have two options of full and half and changing it has not worked either.
I have tried to use a switch in between the fiber modem and the edge router to try to manipulate the duplex settings, but when i tried it the port simply shutdown and then i have to reverse the configuration.
The software version of the router is 12.2(33)SRE3, i really need to sort this out as connection to and from the Data centre is quite slow.
Some of which use snap and some use mux, the router is the one will start the connection and will always be on, untill there is a power cut, if there is. At this point when the power comes back on and a packet's destination is the outside the router should initiate a connection over the atm.
•Do not use this feature on a router that initiates PPPoA sessions.
•This feature supports ATM PVCs. Switched virtual circuits (SVCs) are not supported.
•PPPoA does not support static IP assignments within virtual templates.
The second and thrid I can understand and the 3rd will just get assigned an IP address from the ISP.But with the first point how is it possible to set this up when the router cannot initate the connection?

View 1 Replies View RelatedI am trying to sort out an IP problem on my mates PC. I have setup a Linksys wireless router on his home broadband and it works fine with my laptop and gives me a DHCP address. When I try to connect his home PC either with a wireless dongle or ethernet connect it gets a Public IP address through the router and not one of the DHCP addresses. Even if you give it a static IP address and setup the router to accept it when you turn the PC on it still gets this public IP address. It is associating with the wireless router but only gives a local connection. I have done the ipconfig and it just renews the public IP address to a different one

View 1 Replies View RelatedI got a simple office: one flat LAN, one single 1841 router and 2 ISPs.LAN is 10.10.20.0/24 and is connected to a port on an HWIC card I installed in the 1841. Then FA0/0 connects to ISP1 and FA0/1 connects to ISP2.
Everything is fine except that I am having some issues with the Failover feature. Currently, I am using Object Tracking with SLAs. I am pinging 2 hosts located on the internet and then I have an SLA OR statement which basically say if ANY of the 2 objects are unreachable, DO NOT trigger a failover to ISP2. If in the case that BOTH objects become unreachable, then DO trigger a failover. It works like a charm.
The problems:Any internet hiccup obviously makes the router activate the tracks and redirects all traffic to ISP2. However, 99% of the time ISP1 is back online within minutes or seconds, so after 180 seconds the traffic gets redirected back to ISP1. So in essence, the customer suffers 2 interruptions.
Besides internet hiccups, I have also noticed that every time any user tries to copy a big file accross the tunnel (the 1841 has site to site tunnels with 2 branches) the tracks go crazy and the objects become unreachable so a failover is triggered. We were breaking our heads and fighting with the ISP1 provider because every time this happened, we called them but every time they kept telling us that their line was UP and running without any problems. So after careful investigation, I do admit they were right.... it is not so much that the ISP1 experiences hiccups, it is actually the fact that users putting heavy load into the router are causing it to have its track to stop reaching the objects.
I have Cisco 2651XM and currently running old IOS c2600-is-mz.123-26.bin (IP PLUS) which I used the NAT protocol. I was wondering can I use IP-BASE on this router and I am not sure if this feature set has NAT protocol.

Now I setup my computer to auto-shutdown at a particular time via cmd, but I want o know whether it is possible for me to put some time settings in my modem+router so that it switches off at a particular time or something like that.Then when I get up next morning, start using it again. I don't want to keep my router on after it's not needed. Also I don't wanna keep it vulnerable after it's not needed, even though I have set it up quite securely. ( WPA2 PSK, and MAC filtering)

View 8 Replies View RelatedI'm a bit confused about what a wireless range extender gives me. I have bought a Sitecom Wireless Range Extender 300N. This extends the wireless range of your router to parts of the house that have a weak signal or none atall.
It is setup correctly and is working fine, however, the SSID is different from the Router.
Essentially, I want to extend the range of my router to parts of the house that have a low signal. This range extender seems to be the correct product to do this. However, I want my clients to switch to the appropriate wireless access point (either the range extender or my router) depending on the strongest signal, how can this be configured?
When a client is the overlap area (the area where both the router and the range extender can be sensed) I want the client to switch to the strongest signal.
In my case My Router is in the loft and the range extender downstairs. You can still get a low signal from the router when you are downstairs but the range extender give a full signal. However, I dont understand what makes a laptop 'switch' from router to extender when its downstairs.
Because the extender has a different SSID a laptop that can still get a low signal from the router when downstairs doesn't automatically attach to the extender to get a strongest signal.
If I set the extender to have the same SSID as the router
