I just recently upgraded my 3845 to 15.0.1M9 and everything was going fine until I turned it back on later today. It is now stuck in a loop and wont even allow me to access ROMMON. I took out all additional hardware and it is still stuck at this screen. [code]

I have a Catalyst 3560-X PoE that suddenly stopped working. I plugged in via console and below is the output I received. It scrolls constantly and I am unable to enter ROMMON mode or stop it from scrolling. I've read of a possible problem with the IOS version but I'm unable to verify due to not being able to stop the scrolling.

View 1 Replies View RelatedI have a couple of 3560 switches running c3560-advipservicesk9-mz.122-44 and they are randomly experiencing the following:
- The switch locks up with no preceding error message in the log (I am forwarding syslog to Splunk).
- Upon reboot, the switch goes through the normal startup sequence with no error messages, then for some reason reloads the flash and starts all over again. (refer to doc)
This could happen after days or weeks. Sometimes they will go through two of these reloads on boot and be fine for awhile, and other times they will be stuck in the loop infinitely. I am using this same image with all of our 3560s, but am only having this issue with two of them.

View 1 Replies View RelatedAll my switches were connected together as ring topology. We use REP to block redundancy link.One of my colleagure was setting up a new link(VLAN) for one customer which was then caused a L2 loop. The CPU was hitting 100% and REP started to lost neighbors then we had a big outage.I am thinking to deploy QoS on all REP switch (on trunk links from switch to switch) to give priority to control traffic like REP and some importance data VLAN. Of course,Storm-Control already implemented on all access-port.

IOS = 32M

However, when I power up my router, it goes into a boot loop, and I see the following messages:

how to overcome this error, and successfully upgrade, so I could load my new image?
I recently had to deploy about 4 cisco 1131 AP's to one of our branch location. When configuring them on the controller, i needed to put them in HREAP mode. As soon as i do that and the AP needs to reboot, it will continue to reboot in a loop and indicate the following:

Our company has a handful of sites that use the EasyVPN technology.On my remote router (Cisco1841) - I add the crypto inside to the FA0/0 and the Loopback0 interface.On the other end my Cisco ASA 5580 - 8.41 code - I have RRI enabled and the tunnel comes up fine.However I only see the static route from the fa0/0 interface on the remote router. I can not figure why I can not see the Loopback0 address?Wondering if this is a limitation or feature not enabled.
I added multiple interfaces on the Cisco 1800 and can see the networks.I run "show crypto ipsec sa" on the Cisco ASA and see the spi encaps/decaps for the loopback, but the SH ROUTE does not show the static route being injected.
We are setting up one of these for the first time. It is in a constant rebooting process.
Here is the boot process:

I recently replaced a client's router with a Cisco RV 120W. The client employs a web-based application on an internal server that manages their business. Workers in the field use a handheld device power by WIndows Mobile to access a mobile version of the the web-based app. Data contained on the mobile app syncronizes with the server when workers choose a sync menu. Some workers perform this sync in the field, others wait till they return to the office and use the wireless provided by the router. Prior to changing the router, the synching worked fine either inside or outside the company network. The mobile app accesses the internal server via the router's public IP address. The router forwards the http requests to the internal server. But now the synching does not work internally. I assume it's because the Cisco RV 120 W does not support NAT Loopback, or I simply haven't figured out how to enable it. Does anyone know how to enable NAT Loopback on the RV 120 W so I can access the web-based app by through the router's external IP while on the private side of the LAN??

View 7 Replies View RelatedWe have 6 WAN routers connected through ISP MPLS cloud , we need to implement GET VPN between these WAN routers.We have 2 Key servers (1800 routers) , and the WAN routers will act as Group Members (6 GMs)
The attached configuration files are for working configuration for typical GETVPN (crypto map applied on WAN interface)
In Key server configuration , the crypto isakmp command is using the WAN interface IP address of each WAN router (172.16.x.x) , and since that the KS routers are connected to local backbone (VSS) , they should be able to reach 172.16.X.X , and therefore the subnet 172.16.X.X is advertised to the local network (check GM configuration file under eigrp - redist connected )
This is what our customer want to avoid ! they do not want 172.16.X.X to be advertised to the local network .I know It is possible in GETVPN configuration to configure ,the crypto isakmp command to use loopback address's of the WAN routers instead of the WAN IP , but in this case the crypto map must be applied to the loopback address , and this requires all traffic to be encrypted and decrypted to go through the loopback interfaces on all WAN routers .
i was wondering what is the best solution for this case , I though to use the below config on the GM's

I am trying to reproduce a Spanning-Tree loop in my lab that occurred on Ops, and for the life of me I cannot break it. The loop is very simple:
Cisco 2960------------FW that doesn't forward STP traffic-----------Cisco 2960
This created an STP loop. In my lab, I am substituting the FW for another Cisco 2960 with STP disabled and BPDUFilter on ingress/egress ports to stop the switch from sending BPDU's to the downstream switch to keep it in the dark, as the FW did on Ops.

A week ago I actualy successfully implemented and tested HA scenario with two 5500 controllers (one of them with the HA SKU code). Both of them were upgraded to 7.4.100 version, but today the bckup controller has gone insane! The HA sceanrio was broken down and the bckup controller loops in "Enter credentials" loop forever! It doesn't matter what I enter, how many signs, it just loops endlessly... I bolded the console output underneath...

I am working with a device that does not have a physical reset button on it, and have mistakenly typed in 127.x.x.127 for it's IP. I was trying to use 172, but mistyped and didn't catch it until after I had rebooted the unit. Is there anyway that I might be able to gain access to the device. My PC is running Windows 7, but I am familiar with linux as well. I have attempted to change the loopback adapter IP to 128 on a ubuntu live disc and set my ethernet port to the subnet the device is on with no avail. (I am also using vlans on the device, but believe I have them set up correctly)the device is set to IP: 127.x.x.127 netmask 255.255.255.128. [code] I know that the last octet of 127 is the broadcast IP for the range, but have been able to address similar blunders before by forcing myself to a /24 subnet to correct that.

Just upgraded Cisco ISE to 1.1.1 in my lab/demo environment and am now having problems with a basic posture implementation. In short I connect to a wireless SSID and check posture based on the presence of a file. The NAC agent is declaring my host as compliant and granting full network access however about 5 seconds later it it checks for requirements again while placing my host in the temporary network access. At this point it states I am compliant again and 5 seconds later scans again. This behaivour does not stop and continues endlessly until I close the wireless connection. I had no problems with this setup on 1.1.All logs indicate successful compliance and no errors in terms of compliance.
View 33 Replies View RelatedI've got an SG300-10P switch and am trying to use it to create a testing environment for a Fiber Test set. What I would like to do is get two hosts, A & B, plugged into ports 1 and 3 on the switch, to talk to each other, but forcing the traffic to be routed through the two Combo ports 9 & 10. Please see the attached diagram.I've attempted to configure two VLAN's, 10 and 20. Vlan 10 is used for traffic between Ports 1 and 9, Vlan 20 is used for traffic between Ports 3 and 10.I don't really care whether the traffic is tagged or untagged as it passes between ports 9 and 10.
I've tried various combinations of tagged/untagged ports, PVID's, etc. As a first test I've bypassed the Fiber Test set and simply created a direct connection between ports 9 and 10. I am unable to get the traffic from Host A to Host B to get routed through ports 9 and 10 (I ping each host from the other and get no response).
