Cisco VPN :: ASA-5500 Fail Over Synchronization
Feb 28, 2013My client has two ASA-5500 in failover (8.4.4.1).To create AnyConnectVPN, the package must be uploaded on both machines - uncomfortable, but it can be accepted. The REAL problem is that the profiles (.xml file) are not synchronized.When I make a change of any of the parameters, after failover switching I loos alle the change.

Jul 23, 2012The setup is a S2S VPN with failover to 3G HWIC in a Cisco 1941 however the IPSEC tunnel needs to remain up through 3G if ADSL fails.The failover works ok, however when plugging ADSL back in, the - "sh crypto session" shows both dialer 0, and dialer 1 with the crypto map session to the other side of the VPN and either side is now not pingable.The NoIP DDNS updater client runs on a server in the network and all IP resolution to host1,host2 works ok (other side of VPN is Cisco 1921 with ADSL HWIC and 3G HWIC).

Feb 22, 2012We have two Cisco 2960 TT-L switches. I'd like to reduce single points of failure and have dual servers for most tasks. For example, two firewall servers and two web servers. Should one server fail the other will act as a failover.I'd like to extend the redundancy to the switches, and am thinking of connecting one web server to one switch, and one to the other. In the event a switch failed a set of servers would still run, and be able to talk to each other.I'd like to run two VLANs, one for the LAN, and one of the WAN, and connect the two VLANs on each of the switches with the associated VLAN on the other switch.

View 1 Replies View RelatedCisco Switches :: (S)NTP Synchronization On SG300 Access?
Nov 17, 2011In our network two Domain Controllers are configured as the central (S)NTP Servers. For a switch in Layer 3 mode it is quit easy to synchronise with these (S)NTP Servers. But what is actually the best approach for access switches in layer 2 mode, that are connected to the layer 3 switch? The only IP Address they have are part of the management VLAN ID 1 which is not routable. I am actually looking for something like a broadcast without having to put a NTP Server in management vLAN.
View 4 Replies View RelatedCisco :: Time Synchronization Via NTP Between Catalyst 2960 And 6509?
Jul 1, 2012I have a problem with the time synchronization via NTP between a Catalyst 2960 and Catalyst 6509. When I configure the 6509 switch as a NTP reference on the 2960, it does not synchronize with the 6509's NTP server. There is no reachability or ACL-related issue between both switches.
As soon as I configure a second Catalyst 6509 (which is completely identical to the other 6509 and in the same subnet) as a NTP server for the 2960, the time sync with the second 6509 happens immediality.
The first 6509 switch works as a NTP reference for at least 50 other switches and routers in the network - so why not for this one more switch? I checked some "debug ntp packet" and "debug ntp events" outputs and can clearly watch the NTP requests going out of the 2960, but on the 6509 just nothing happens - no debug outputs for this specific 2960, while requests from other devices come in all the time.
Maybe you have already experienced this strange behaviour in the past or got some deeper knowledge in the Cisco NTP server implementation. I could think of some sort of "maximum client limit" in the IOS NTP server, but could not find any mechanism like this in the standard NTP specification. Eventually, you can approve that this is a IOS-specific issue.
Cisco Switching/Routing :: Nexus 5000k Synchronization
Dec 11, 2012I have a Cisco Nexus Datacenter solution with this design:Every Nexus 5K is connected with every Nexus 2K with a Port-Channel and vPC.
What is the best way,to keep the configurations of the nexus switches synchronous? I have no DCNM (Mgmt.-Tool).
My problem is if I configure for example a Nexus2K-host port on one Nexus 5K, the change has no effect. Only when I make the same change on the second N5K the port-config really changes.
Cisco Switching/Routing :: 6500 - Native IOS Image Synchronization?

Can this be done on IOS? I was looking fot this over the Internet and couldn't find anything.
View 1 Replies View RelatedCisco Switching/Routing :: 3750 Switch NTP Time Synchronization Triggers IPS
Dec 20, 2011I've beating my head against the the above said problem for a quite a while. Our client has a very strict security policy and they require all standard protocol to comply with the expected behaviour. It was discovered that their 3750 switch running c3750-ipservicesk9-mz.122-25.SEE3 software and configured to sync its time with an external public NTP server triggers IPS signature - DNS Info leak. The problem is that the switch initiates the packet on UDP port 53 and not as I would expect on port 123 for NTP. Of course I can tune the IPS sensor and make it not to fire this signature but the client needs to know why it is happening and if it is faulty IOS software that doesn't comply to the rules.

Dec 13, 2011My company is moving the datacenter to our new building on Saturday, however the users will remain at the old building until late next month so they bought a 100M Metro E VPLS circuit through their ISP. I went to test it today but could not ping the workstation from my laptop. I wanted to do some bandwidth testing with iperf but could never get to that point because ICMP connectivity wasn't even there. From what I understand, VPLS is just a layer 2 extension so they way I'm testing the circuit below SHOULD work, but it isn't. Spoke with the ISP and they tested the circuit end-to-end on their equipment which was fine so am I missing something?

View 5 Replies View RelatedCisco WAN :: 2811 - PBR Testing Is Not Working
Mar 15, 2011I am deploying PBR at the moment in a simple configuration. The 'ip policy' is applied to a sub-interface on a 2811 and all ACLs and route-maps look good. I am using NAT also in this configuration. It is a very simple build, basically stating that all traffic inbound on this sub-interface is to use a next hop of x.x.x.x
My testing is not working, but i need clarity on this. For different reasons, i am not able to tests with hosts on the relevant VLAN yet, as there is not. So i am testing on the local router using the sub-interface as the source IP. i.e. 'ping 8.8.8.8 souce int fa0/0.99' or telnet www.cisco.com 80 source fa0.0.99
Nat appears to be working, but my debug on ip policy is not showing any hits. Will my tests work when i am sourcing packets from the locally connected interface?

Apr 19, 2010Has anyone tested QoS on the new E3000? Whenever I add an application (e.g. Voice Device) and set priority to Medium or High, my upstream bandwidth for everything else is immediately cut significantly, even when I'm not using the priority application.
For example, with QoS disabled, I can consistently get 10Mb upstream (speedtest.comcast.net). As soon as I enable QoS, upstream is capped to exactly 2Mb! On my old router, there was an option to set the total upstream bandwidth -- but on the E3000 there is no such option that I can find.

Jun 22, 2011I am working at a client site today. The client has a large Frame Relay Hub Spoke network. The Hub is at the HQ location, and then there are about 15 spoke sites in remote offices.
We are having an issue with the frame between the HQ and one of the spokes. We are currently working with our dear friends at AT&T to troubleshoot the issue. AT&T yesterday was trying to run a local loop test to the router at the remote (spoke) end. We were working iwth them in trying to put the remote router (which we manage) into a loopback mode. We were trying to use controller commands
COOP-Rappahanock#conf t
Enter configuration commands, one per line. End with CNTL/Z.
COOP-Rappahanock(config)#controller ?
% Unrecognized command
COOP-Rappahanock(config)#controller
That we seem to run out of options...
How can we put the subinterface that is the other end fo the frame into loopback mode so that a local loop test can be done between us and AT&T (provider)?

Jun 15, 2011We have a 5 node VMWare cluster connected to an EMC NS20 using VMWare over NFS.Right now, our only bottleneck is network and even that is not limiting. We are considering updating our infrastructure and since networking seems to be the the only real issue, they want me to research that first.So I thought I would get a server, throw in a 10Gbe NIC, get a cheapo 10Gbe switch, get some cheapo NAS (or build one) that can do 10Gbe and start testing...Wrong. What a CF 10Gbe still is. At first I just assumed I'd go with 10Gbe over copper. How naive of me. So once I realized that the most "cheapo" 10GBase-T copper switch would run me about $9,000, I shrugged and starting looking at 10Gbe over optics...
IS there a cheapo (relatively) switch out there for someone wanting to test 10Gbe?? Like $5,000 or less?EDIT: BTW, before this goes off-topic into teaming 1Gbe connections being good enough and such, let me say that we are planning for the future here. As I said, we aren't currently limited in any area right now. However, we see that if there was an area we need to focus on, it would be network. So to that end, we'd like to start testing what the future has to offer. We've already tested and are using link aggregation and such at the 1Gbe level.
