I have a Cisco 1941 ISM. It sits between my Fortinet Firewall and the Internet. I tried to console to it so I can backup the configuration. Is there any way I can do this as I do not know the name and password for this unit as the previous net admin is no longer employed.
View 1 RepliesI am an IT professional that is installing my first extended range wireless AP in my companies warehouse. I am very excited!
Now I have set up many a linksys and repeater wireless networks, so when I was looking into the Aironet 1240AG I thought ?No Problem!?
And at first, it is not!
I have the AP and antenna set up here in my office before I take it out and mount it in the warehouse. And I can get connected to it, no security for now, no filters, I just want to connect and make it work.
I stay connected for maybe 3 minutes, I can get to the internet, I can ping all my servers. Full connectivity. But then for no reason the connection fails and I cannot reconnect.
The error I get in the log is
Interface Dot11Radio0, Deauthenticating Station 0006.2510.bbe3 Reason: Previous authentication no longer valid
So strange! So I have reset the AP to factory defaults and then set the SSID, and I can connect, again for a second, then nothing.
I have tried with multiple wireless cards, even laptops. Thinking maybe the problem was on the computer side.
We currently have two 6509's running in VSS, both switches have a WS-6748-GE module in slot 3. I'm in the processing of removing these modules. I will then be replacing them with a different module type, but I need to know how to remove the old configuration of the previous modules.

I have this Cisco 1941 router with two Ethernet ports g0/0 and g0/1. The g0/0 is connected to office LAN with internet access. As my office LAN is DHCP, it will assigned a IP address for g0/0 since this g0/0 is configured as "ip address dhcp". Now my question is that i have a group of 5 pcs, namely PC1, PC2, PC3, PC4 and PC5 that is connected to the switch and one of the ports of this switch is connected to g0/1 of Cisco 1941. Is it possible that let say PC2 and PC3 (both DHCP enabled) could access the internet access from g0/0 and at the same time, the office LAN assigned IP address for PC2 and PC3 automatically?

I have a strange behavior and a simple proble . I configured the following static route
ip route 10.84.22.0 255.255.254.0 10.84.23.254
That I advertsied in eBGP :
router bgp 65000
network 10.84.22.0 mask 255.255.254.0
the IP next hop 10.84.23.254 is cascaded on my customer LAN . At nominal time the router advertsed the route in BGP
pjnb1376#sh ip bgp nei 57.213.169.169 ad
Next Hop Metric LocPrf Weight Path
*> 10.84.22.0/23 10.84.23.254 0 32768 i
When the lan interface of the router goes down , the router still advertise the route !!! Even if the IP next hop
10.84.23.254 is not reacheable anymore ....
The box is a Cisco 1941 using

I have a client who has Cisco 3800 series routers in their data centre with which they have QoS/CoS policies implemented. They wish to further manage traffic by limiting outbound traffic to their branch sites in line with the network access bandwidth each site has available. Is this possible whilst leaving the QoS policies in place? If so how?

I bought a secondhand small business router (model 1941 Integrated Services Router) for personal use. It runs version IOS 15.0(1)M1 software, which seems to work well, but I'd like to download a firmware update that addresess some of the security flaws in this software. When I tried the download process it told me I need to buy a service contract first? Is this right, or am I doing something wrong?

Recently my company buy a EHWIC4ESG card and put into the cisco 1941. The reason we buy this card is because the in built two network ports of cisco 1941 are being used up. g0/1 is being connected to the internet and g0/0 is being connected to the office switch (192.168.5.x)
We have two servers (192.168.6.x and 158.55.33.x) that required to be connected to this router 1941 where the router will be configured as VPN for external user to access this server.

I have a 1941W that has a connection to my ISP (Gi0/1) and another connection to a remote lab (Gi0/0). Everything is working fine how it is setup. All my traffic from my internal networks can access the Internet and devices on the 192.168.201.0 /24 can access the Internet and the lab 10.89.0.0/16.
Now I want to have two devices (192.168.201.51 & .147) use Gi0/0 when accessing host 63.85.190.67. There is no route to this subnet since it reside in the remote lab. Here is what I have right now. How would I setup a PBR to have those two host use Gi0/0 when accessing 63.85.190.67

What is the procedure to reset a 1941 router to factory defaults? I just recieved my1 1941 router. I connected it up to my Mac using USB. I got loged in using the cisco/cisco login and it said it will only work once and that I should create a new account. So I entered the command as directed on the screen and it gave my an error about the command. I verified it three times and each time it rejected. While I was looking online for an answer the connection timed out and now I can't get back in.
View 1 Replies View RelatedI decided recently to switch out our border router (1841 12.4 advsecurity) with a shiny new 1941 (15.2 SEC/K9) as the CPU upgrade was needed.The core below acts as a VPN end point to various other remote offices we have, all of which have a similar network design at each end (and all entirely managed by me). All of these are still running 1841's with 12.4 advsecurity on them as well. These are all GRE tunnels with ipsec procection on them (not crypto maps). [code]
Everything else works fine (NAT, route-maps etc), it's just these IPSEC/isakmp tunnels that are not playing ballIt's definitely not an ARP issue (all arps were cleared) and ICMP appears to work fine (ie, I can ping the remote tunnel's public IP endpoint from the core using the loopback for that tunnel as the source). I am suspecting it's something strange with the stateful firewall config, but I did try and apply ipsec and isakmp-msft to the ip inspect list, with no success.
I don't have access to my config at the moment and I haven't had a chance to get to the console of this router as of yet.A little background info:This is a Cisco 1941 router in which I have multiple NAT inside interfaces for internal VLANs. Before my current problem I was using one NAT outside interface for Internet access with another NAT outside connecting to our corporate network that was in a shutdown state.The router is performing router on a stick and had layer 3 subinterfaces for each VLAN. I have ACLs filtering on each subinterfaces allowing only the traffic I need through.I also currently only have one static NAT port for an FTP server.The time finally came when I had to connect our corporate network to this router via an access port on a 2950 which trunks to the router.The problem comes when I send any traffic to the subinterfaces on the corporate network which is the second NAT outside interface on the router. The main point for this connection is to do a static NAT from this interface to a web server on another VLAN. Any traffic to this interface including just pinging from the outside causes connection to the router to fail for about 3-4 min.Like I said I haven't ha the chance to get to the console yet Sony cant tell everything that happens. Nothing shows up in the logs after I can get connection back and the router didn't reboot as a "show version" says the router has been up for a long time.The CPU is also usually very low as not that much traffic flows through this router at a time.I built a very similar network in packet tracer and it works just fine.

View 6 Replies View RelatedI'm setting up a lot of small remote sites that are only reachable via VHF ethernet radios that operate at 32k. I'm going to be using 2 of these radios shooting to two seperate base station radios to provide diversity. I'm going to have a Cisco 1941 sitting between the two radios and the way I have it configured now is to only use one radio and the second is only sitting there in case the primary fails. I was thinking though that I could load balance them to give a little more throughput. The devices at these sites are really low speed but we like to use snmp to monitor everything that is ethernet so I wanted to give as much bandwidth as I can.
Will load balancing work in this situation? What would the basic configuration be? This is all internal to our network so there are no ISPs to deal with. We're using C1900-UNIVERSALK9-M IOS will that work or will I need to change that?
I have been recently asked to design a network. What I have for equipment is four 2960G's and one 1941 router. One switch is a root switch and the other three will have end devices on them.I have decided on three V lans to go with: VLAN20 Data, VLAN30 ISCSI, and VLAN99 Management each with seperate trunk links and redundancy (see picture below).
I have a seperate trunks for each V lan using the switch port trunk allowed. With exception to the Data V lan.My design has the Data V lan as the native because it is going to be receiving untagged traffic from the external network. I have set up inter v lan routing on the 1941 via sub-interfaces to allow them to talk to each other (or because of allowed they cannot?). I have one port coming from my router to my switch via Ethernet cable which is my bridge out. I have my external port doing a NAT translation for my inside addresses and a Default route set up ip route 0.0.0.0 0.0.0.0 gig0/0. I am using rapid- PVST to prevent loops and provide my zero downtime convergence when a link goes down. As it stands right now I cannot talk out of my network or inside of my network.
You can see it is highly redundant and I do not want to change it. This network is going to be deployed but there will never be anybody physically there to manage it which is why I made it as redundant as humanly possible.
