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'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.

i have 2 x T1 terminating on border router cisco 3640 route. (configured using multilink interface). Our IP block is routed on this bundled T1 circuits by At&T. I want more internet bandwidth.
1. Can i connect my DSL (on ethernet interface and using static DSL IP) on the same router and confgure two static routes to internet - one to multilink interface and other to ethernet interface (connected to DSL) ?
2. I have many servers using static NAT to external IPs which are routed on T1 circuits. Will it get into issues when communicating to outside? [for example my exchange server, websites etc?
I have a dual 5508 controller /NCS deployment. I deployed my first clean air AP today, a 3502I.
The Clean Air feature does not seem to work, however. "No information is available because CleanAir is disabled or otherwise not available for this radio. If no information is available and CleanAir is enabled then you can try rebooting the AP XXXX".The thing is that CleanAir is enabled on this AP.
Work connection will load database about a third of the way then crash laptop. I can change out the router from the new Cisco e3000 to an old wireless router and it works fine.

I read that the system uses location, signal strength and coverage data in conjunction with monitor mode APs at each exit to trigger the roam. I just don't know if MIR does this on it's own or needs to get location from Context-Aware service.

I know it's not the Internet itself, since it's only happening on my computer, and none others in the house - and I'm far from capped. I've run AVG, Spybot & Malwarebytes' scans and have found no infections of any kind. I've run TCP Optimizer and used the "reset to windows default settings" feature, which also hasn't worked one bit. I've tried different Ethernet cables and different plugs in the modem and no improvement.

View 7 Replies View RelatedA customer has an ASA5520 and 2 ISP routers with one WAN link each, and wants to split the load over both routers based on source IP ("natted" IP on ASA). I found this excellent doc on the topic: {URL}. Using PBR to achieve this is an option I was looking at, but I have come across a possible loop doing this with 2 routers. Setup:
-----------CE-1---------ISP-1
| |
| |
ASA55020---- HSRP |
| |
| |
-----------CE-2---------ISP-2
Both Routers receive default routes via BGP, and customer networks are propagated via BGP as well (i.e. the customer can specify the return path for the traffic). The ASA5520 forwards traffic to a HSRP virtual IP for redundancy purposes. If one router or ISP fails, all the traffic should use the other router/ISP. The customer wants to specify which traffic is sent over which link, by defining nat rules on the ASA. e.g. traffic sourced from the network 10.10.1.0/24 will always use ISP 1, and traffic sourced from the network 10.10.2.0/24 will always use ISP 2.
My problem: if I use route-maps on both routers (CE-1 and CE-2), sending part of the traffic to the other, and one ISP link fails, in my opinion I have a loop, since part of the traffic will get sent back to the router it came from. Is there any other was to achieve my goal without using PBR? I have looked at CEF and GLBP, but I cannot seem to find a way to load share via source IP.
Can an ACE 4710 have , in the same context - servers which are
a. just being routed to
b. a set of load-shared servers
I have been told you may not be able to do this on this version?
We have our network setup as displayed in the attached. We have 2 HQ offices and 1 branch office. The branch office needs to connect to resources located at both HQs but taking the most effecient path. We have ethernet circuits connecting from each HQ to 2 x Cisco 3560 switches in the branch. HSRP has been configured on the 3560 switches with SW1 as active and SW2 as standby. OSFP has been configured in a single area 0 and the path cost on the link between HQs has been increase to allow 3560 SW1 to route to HQ1 directly and HQ2 via 3560 SW2.The 3560s are connected with a trunk with a L3 SVI for OSPF. This seems to work ok but I have noticed that the branch could become transit if the HQ1 to HQ2 link breaks. How can this be avoided? I realise that if we configure the branch subnets and SW1 to SW2 link in a stub area (area1) then all traffic will route from SW1 to HQ1 and will never share over SW2. I'm assuming that this is because OSPF chooses inter-area routes over intra-area.
View 4 Replies View RelatedI have a internet router 2921 .my isp is providing 100 mbps internet link with static public ip network .I am using a default static route to the isp wan ip .I am planning to upgrade 100 mbps to 114 mbps .Unfortunately my isp doesnt have gig port in their side .So they are ready to provide two 57 mbps line .Isp agreed they will route my public ip networks in both the links .
As a result i have two 54 mbps link with same network with two wan networks .My question is whether two default static route to both wan ip will carry out the load sharing correctly ?
Eg :

I have 2 x Redundant Guest Anchor Controllers (5508) located in 2 separate Data Centers with all the management and guest user VLAN spanned between two. Everything is working fine with the Guest WiFi access except the DHCP functionality as the Controllers are acting themselves as the internal DHCP Servers.
This is how I tried to distribute :
network. 10.1.0.0/23
gateway: 10.1.1.254
Controller 1, DHCP Server pool: 10.1.0.2 - 10.1.0.254 Gw: 10.1.1.254
Controller 2, DHCP Server pool: 10.1.1.2 - 10.1.1.254 Gw: 10.1.1.254
As the user load balancing between the Anchor Controllers cannot be controlled (i.e. they are active/active), the same client sometime getting 2 different IP addresses from both the Controllers (as they do not talk to each other in terms of DHCP) hence depleting the pool addresses.
I guess one way of solving this is to just run 1 DHCP server in one of the controllers but that defeats the purpose of having N+1 Controllers. Is there a better way of doing the DHCP load balancing and having full redundancy at the same time?

I'm in a house on a network that has 2 Macbooks, 4 notebooks running either Windows Vista or Windows 7, and 3 desktops running either Windows Vista or Windows XP. (Sidenote: No, they're not all accessing the network at the same time; actually some of them are hardly ever even turned on but it's important to include them because of the questions to follow.) Out of all those machines, one desktop running XP and one notebook running Vista are mine.Now, my family's pretty private, so we have file sharing turned off on all the computers. The problem is it's really a pain to have to transfer files between my laptop and my desktop, which I do fairly often because some of my schoolwork is done on the desktop (bigger screen), while some is done on my laptop (portability), and I also have a partition on the desktop's hard drive specifically for backing up files. When I want to transfer files, whether it's one file or 10,000 files (which I had to do the other day, actually), I either have to:
a) e-mail the file to myself if it's not too large and open it on the other machine
b)use my flash drive to transfer files
c) use a usb transfer cable, start the software, log in to the connection, etc etc.
simply create a new Workgroup on the network with just my 2 machines in it, so I can put all the files I want to share/move between them on the network instead of manually transferring them. I've already taken care of that step (creating the Workgroup, that is), so for the sake of not being confusing, I'll call my network "Network" and my workgroup "Mygroup" and whatever workgroups the other computers might be in "Theirgroups". Now that I've figured out that it's possible for Mygroup and Theirgroups to co-exist on Network, what about the actual file sharing? If I set up file sharing will only the 2 computers in Mygroup have access to them, or will the computers in Theirgroups have access as well since we're all on the same network? If the computers on Theirgroups will have access as well, is there any way I can make it so that only Mygroup will have access?

For some reason today my desktop stopped being able to share media with other computers and devices.I mainly use PS3 Media Server to stream and download content to multiple devices including my PS3, Xbox 360, iPad, and iPhone. Now none of those devices can see the server. I tried restarting it, restarting my computer, and updating to the latest version.I've also tried turning on other media servers like TVersity and Windows Media Player and none of my devices can detect any of those either, so there must be something wrong with my desktop's networking (but it can still get internet). I haven't made any changes to my home network since yesterday (the last time I used my media server).My desktop runs on a wireless network with a Broadcom 802.11g Network Adapter, my router is a Netgear WGT624v4, and my cable modem is a Toshiba.

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.
