Acquired a 3875 Router with a NME-16ES-1G-P switching service module recently. I don't know what the passwords are. I reset the router, and gained access to it, but how do I reset the password on the service module?

View 1 Replies View RelatedI recently decomissioned an 871 from a small business site and the owner did not want the device anymore. So now I'm trying to use it back at the office in the sandbox, however I don't know the password to the device and neither does the business owner. There's a reset button on the back, but from what I've read (here), it only loads a different config file found on the internal flash. Tried this, no dice. Is this essentially a bricked router now or is there anything else I can do to clear the config and repurpose it for my use?

I am using the correct bin file as I checked with my pix version. Also I CANNOT ping the firewall from a PCor system on the network, but CAN ping everthing from the PIX.I've tried using interface 1 but no go. Also I've checked the TFTP software (Solarwinds) is running fine and I've unblocked it in XP's firewall.

have a Switch I bought off a guy at work. Just to get into the Switching world of Cisco. He doesnt know the password on it and i cant reset the switch. I would like to mess around with it more but it doesnt load the flash or helper. It just sits there and holds. I have tried the password recovery and everything. Trust me, everything is correct, but it wont work for me. I cant load a new image to it because I dont have access to a server to get it from.

how to recover password and retrive configuration on Cisco switch 2950 and 3560.I know the way to press and hold the mode button and then plug in the power cord can reset the switch to factory default but it will reset everything to nothing. As such, it is not what I want and I want to keep the configuration file and able to use the configuration on the switch.

Does any know what " Last reset from system-reset " means? Is this becouse of a power failure or someone reloading the switch?

We currently have a Cisco 1841 router with version 12.4(1c) of IOS using image c1841-ipbase-mz.124-1c.bin. Our goal is to make it so our router can fully support IPv6. The current IOS version cannot. I've seen a site that seems to indicate 12.4T does support with IP Base image but recently had Cisco tell me with the latest IOS release 15.1.4.M4 that I have to use either the "Advanced Enterprise Services" or "Advanced IP Services" image. Did Cisco just remove IPv6 from IPBase in later IOS releases?
Also I've seen conflicting specs on the max amount of Flash and DRAM the router can support. The following link shows that 384MB is the max for DRAM and 128MB max for flash. We're looking to upgrade ours from 128MB and 32MB respectively but as mentioned I've seen it where higher amounts are supported. In fact we bought a backup 1841 to have and it has a 256MB Flash card in it.URL
Last but not least. Where can I find a straightforward documention of this situation where we may have to upgrade our Flash and DRAM and then upgrading the IOS?
I have got a l2 link of 512 kbps from two different ISP. I want to aggegrate the bandwidth of this connection so that I can feel like having 1 mbps connection. I am not actually talking about load balancing, but bandwidth/link aggegration. Can we have the solution of failover with different vlan from different isp ? Can we be able to make the link as a single link.

I'm at a FOX affiliate TV station, and in order to connect our EAS Device to the internet & Fox Splicer, I need to setup a Statio NAT, so we picked up an 1841 on eBay.
I've done a little configuration in HyperTerminal.
I've done these ip addresses:
FE0/0 10.1.10.13 this is the subnet our EAS device is on
FE0/1 10.110.81.174 this is the subnet of the Fox Splicer.
I need to have NAT translate 10.1.10.11 to 10.110.81.170 and I also need to set a route for 10.110.81.0/24 pointing to 10.110.81.161
I have the following devices for our IT Test LAB
1. Cisco 1841 with 2 Fast Ethernet interfaces fa0/0 & fa0/1
2. Cisco 2960-S
3. Speedstream 6200 DSL Modem ( PPOE Connection with Static IP address)
I want to connect to the internet using the current DSL connection we currently have .
LAPTOP --> SWITCH 2960 --> ROUTER 1841 ---> DSL Modem ---> ISP
Troubleshooting 1: Currently from the LAPTOP i am able to ping
1. Switch 2960 Vlan interfaces
2. Router 1841 fa0/0 & fa0/1
BUT can not Ping the DSL Modem LAN interface IP 192.168.2.1 and can not get out to the INTERNET
Troubleshooting 2:currently from the Switch 2960 i can ping
1. All the Vlan interfaces on the Switch 2960
2. Router 1841 fa0/0 & fa0/1 interfaces
3. Laptop A & B
But can NOT ping the DSL modem LAN interface IP 192.168.2.1 and can not get out to the internet
Troubleshooting 3:Currently from the Cisco 1841 router i can ping
1. All the Vlan interfaces on the Switch 2960

View 1 Replies View Relateddue to upcoming changes to our network I'd like to be able to pass vlans across the FE ports of a Cisco 1841 router.1 port would go to a managed switch and then to local devices on different VLANs.the 2nd port would go upstream to a Cisco 3825 at a different location which would then connect to the internet.due to monitoring behind the Cisco3825 we would like all NAT to occur on the 3825.
what I would like to happen is this example device connected to port 7 on managed switch gets an IP (10.0.7.10) from the Cisco 1841 in VLAN 7 (10.0.7.0/24).traffic from that device goes to the switch, then in f0/1 on the 1841 and out f0/0 still with the same IP info, no NAT occuring.traffic is received on the 3825 port 0/1 and then NAT occurs and out port 0/0 to the internet.
I have 10Mbps internet speed connected to ciusco router 1841 that has 2 internal NICs. One NIC has a full 10Mbps download speed and the 2nd NIC is currently limited to 1Mbps download speed. I want to change the download speed of the 2nd NIC to 4Mbps? How do I do this on a cisco 1841 Router?
View 8 Replies View RelatedThe issue is occuring on our local LAN where my ARP requests are being modified after a period of time by the router for one host. I'm finding that the host will work fine with the correct MAC IP pairing for a period of time and then about 15-30 minutes later, the arp table is changing so the associated mac/IP address is now the mac address of the router interface.
The FastEthernet 0/1 port has no ip proxy-arp enabled and is set with ip nat inside.This only started happening after restarting the router, however the running config was saved as the startup config prior to the restart.I've tried hard-coding the entry with the command arp 10.15.4.190 c82a.1459.0579 ARPA however that is not working as expected.
The device is an 1841 ISR with the advanced IP Services bundle loaded. Is there some way that the router is viewing my host (provides DNS, Directory Services) as a intrustion attempt and somehow rejecting the packets?
We have a setup of a firewall in between my Cisco 1841 router and Switch.
Cisco Router --> Meraki Firewall--> Switch
Client VPN is configured on the Meraki Firewall but then for the outside users to client vpn in to the network, I have to port forward or open the ports 500 and 4500 to the IP address of the Meraki Firewall 192.168.1.90. [code]
We have a 1841 Cisco router for one of our remote sites and we have the GRE over IPSec tunnel on it (with our datacenter router) for the connectivity. The LAN facing interface becomes UP/Down (status 'UP', Protocol 'Down'). When I login the router and 'shut' and then 'no shut' the interface, the interface becomes UP and everything starts to work. Traffic starts to flow across it. But after some time, some hours or sometimes some days, the interface is again back to up/down status. The router is connected to a non-Cisco switch. I do see some CRC's increasing very slowly, but apart from that there seems nothing wrong with the interface in sho int fas0/0 command:
!
RTR01#sho int fas0/0
FastEthernet0/0 is up, line protocol is down
Hardware is Gt96k FE, address is 0026.cb91.ee48 (bia 0026.cb91.ee48)

View 1 Replies View RelatedI want to know is it possible to check Internet speed directly in the cisco router thru any command or activating any service in the cisco router?.As it is seen most of the times internet speed offer by ISP is different as compared to clients.and Clients most oftenly not satisfied with internet speed The problem is that our ISP has given us 100MB leaased line.But when we deployed in production network the speed is same as DSL.We have reported this issue to ISP they then carried out Iperf test by connecting laptop directly with the ISP router.They have tested the speed and it shows about 94-96 Mbps and argu that it is up to the mark and there is problem at your side(i.e our internal network).Now our internal network has cisco 1841 router connected directly to ISP 3825 cisco router.Our router has minimum configuration as required to pass traffic out and in.Our internal 1841 router is connected to switch to which different clients are connected.We have performed some online tests using different speed checking websites and also perform real time tests by uploading and downloading files.The speed is much low as compared to 100Mbps and it is nearly or slightly higher then as DSL connection. how can we check internet speed in the specified scenario?Is there any command or service available in cisco router to check internet speed as we want to check ISP connection speed directly thru 1841 router?what about authenticity of online speed checking websites?Any specialize software/tool you recommend to check Internet speed in specified scenario?
View 11 Replies View RelatedI've moved a Cisco 887 router from a site where it was used to dial up on an ADSL line to a new site where we have a EFM circuit which terminates at a Cisco 1841 router managed by our ISP. I therefore need to re-configure our 887 router to work as a conduit from our servers back to the Cisco 1841 as its gateway.
I have asked from our ISP and they told me that i need to configure the 887 to use IP address 176.35.140.65 255.255.255.248 and its gateway should be 176.35.140.70. That's great advice in theory but I don't know how to configure this correctly
Our internal network is using subnet 192.168.42.XX which will need to be retained for local devices.
