I've got a 1941 router that keeps on rebooting by itself every minute. currently, there's no power issue.
I've detected the show version returned a bus error. Is this an IOS bug?
ROUTER uptime is 1 minute

What can we do to solve this incident?. Everything was working fine, and suddently the problem arose.
I just installed a refurb'd 3560 48 port POE switch and configured all ports on VLAN100. All Polycom IP 430 phones (with power adapter and without power adapter) constantly reboot every couple minutes. Any Cisco 7960 phone does not constantly reboot and works correctly. When I plug a small unmanaged switch into a 3560 port and then plug the Polycom phone into the unmanaged switch powering the phone with a power adapter, the phone works correctly. So it seems that the 3560 is causing the Polycom to reboot.

Can I force Switch #2 to be the master, then power down switch#1, remove switch#1, insert the replacement, and then power on the newly added switch without shutting down or rebooting switch#2?
View 3 Replies View RelatedI have a C3560-24P PoE switch, running on a very small network with nothing special about the endpoints or the configuration (5 laptops connecting via 1 wireless AP, 1 firewall uplink, a networked printer and one conference room phone using PoE. That's it.) I actually have inline power turned off on all the non-PoE device ports.
We are encountering a very strangle anomaly where if a client attempts to send a print job through the switch, to the network printer, the printer makes a noise as it if's begun to initialize and then the switch immediately goes into a reboot. Also the reboot appears to immediately drain all he batter power from the UPS unit that it's connected to. The unit is an APC SmartUPS 750 (500W, 750VA) and when the switch reboots the load on the UPS jumps to well above 100% until the switch appears to 'level out'. Is that kind of power draw normal when rebooting a C3560?

I'm having some trouble with a 4510 Switch Line Card. I need some recomendations for troubleshooting it.We have some PoE phones connected to the card number 3. When those phones were restarted, they did not go up again. In order to discard wiring issues, we connected the phone directly to the card 3, and the phone did not go up. If the phone is connected to a different card, it goes up correctly.
Additionally, to restore the service, these phones were migrated to other cards, but when we disconnect the equipment, ports in line card 3 remain in an up / up state (and nothing is connected to those ports!!), and only reflect the actual state after restarting the port.What steps could I do in order to troubleshoot this issue?. What should I look for, or how do I discriminate the problem? Might it be a hardware issue, a PoE issue?
we recently purchased L3 daughter cards (N55-D160L3-V2) for our 5548UPs along with the LAN Enterprise Services licenses (N55-LAN1K9).
I installed the cards and Ent Svcs lic this past weekend and everything went well excep that I couldn't enable the EIGRP feature .. apparently EIGRP requires the LAN Base (N55-BAS1K9-BUN) license even when you have the Enterprise lic installed, so I was able to dig up that license eventually (which comes with the L3 daughter card, incidentally). Another side effect of not installing the Lan Base lic is that the L3 card/module will be in an "offline" state until the Lan Base lic is installed. Either way, everything was working normally in L2 mode at this time.
So, here I was thinking I was ready to proceed with enabling L3 - this morning I installed the LAN Base license on one of the 5548s which apparently triggered the L3 Daughter card module to go active and triggered a switch reboot. Ok, not that big of a deal, knew that was probably coming. I expected the switch to come back up normally .. NOPE. The switch went into a continual reboot cycle where the console prompt would appear, then about 30 seconds later, would reboot again.
I finally ended up re-installing the original L2 card and the switch came right up. I see that LAN Base and LAN Enterprise are both still installed as well.
What have I done wrong here? Why did the switch go into a continuous reboot cycle once I installed the LAN Base license?

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?

Is this operation possible? if possible, how to configure inside the router 1941 to achieve this objective?
I have just set up my Cisco 1941 router to my cable internet connection. I have access to everything, but I cant login successfully into Cisco CP.
I set up a new user with level 15 privileges and a secret password. I go to login via webbrowser and I put in my credentials, but I get rejected. I have tested the username and password via the CLI, and it works fine, I just cant seam to login to Cisco CP.
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 ....

I am having an issue accessing the internet from a PC on the LAN. I have configured the PC with the gateway of the router infront of the ISP to test. I can ping from the router to google or any other internet IP. From the PC I can ping to the GIG0/1 (Inside LAN IP) and the GIG0/0 (Outside WAN IP going to ISP) but I can't ping the Next Hop IP of the ISP or anything past that. If I do a trace route from the PC to the google IP address it hits the GIG0/1 Inside LAN IP Address but fails from there. Here is a cut down snap shot of the router configure

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.
The EHWIC4ESG card is put into the router 1941 and after typing the "running-config" command, i could see it create a vlan 1 interface and

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.
