  • NSO and a10 compatibility - ( 06-30-2025 )
  • NSO Developer Hub Discussions
  • Hi,I have just started picking up on NSO and currently we are in process of importing devices to NSO. When i import a10 devices and try to validate simple cli configurations i see that it is actually over-writing and deleting other configs at that level instead of just merging it.For example,Via CLI, i would be doing this a10_device: active-partition TEST a10_device[2/1][TEST]#configa10_device[2/1][TEST](config:1)#class-list TEST ipv4a10_device[2/1][TEST](config:1-class list)# 10.10.10.0/24 lsn-lid 2When i add above configuration via cli it merges and updates the class-list TEST to now have 10.10.10.0/24 subnet with lsn-lid 2.When i try to do the same via NSOuser@nso(config): devices device a10_device config active-partition TEST class-list TESTuser@nso(config-class-list-TEST)# 10.10.10.0/24 lsn-lid 2if i do a commit dry-run it shows me that it's removing all existing configurations user@nso(config-class-list-TEST)# commit dry-run cli {    local-node {        data  devices {                  device a10_device {                      config {                          active-partition TEST {                              class-list TEST {             -                    cl-type ipv4;             +                    v4 10.10.10.0/24 {             +                        lsn-lid 2;             +                    }             -                    v4 10.10.1.0/24 {             -                        lsn-lid 4;             -                    }             -                    v4 10.10.2.0/24 {             -                        lsn-lid 5;             -                    }             -                    v4 10.10.3.0/24 {             -                        lsn-lid 6;             -                    } We're currently running a10 NEDs with below versions:packages package a10-acos-cli-3.22package-version 3.22.5.I just wanted to understand if anyone has any experience with a10 and NSO and if i'm missing something simple or it's how NEDs are communicating with devices and that has some issues?

  • Call taking 1 minute to setup from one side. - ( 06-30-2025 )
  • IP Telephony and Phones
  • Call is taking one minute to connect between CUCM and CME Router. The CUCM is 12.0 and it is configured as a CUCM Cluster with one publisher and one subscriber node. The call works fine from both sides (CME to CUCM and CUCM to CME).When publisher is active. But when publisher is down. Then call works fine from one side (CUCM to CME).But takes one minute to set up from other side (CME to CUCM).The CME is cisco 8300 Router. And I am using cisco IP Phone 7965 on CME side and Cisco Video phone 9971 on CUCM. Kindly advice for possible solution.

  • Custom Bounce Message II - ( 06-30-2025 )
  • Email Security
  • Hello @All,This question has been asked before. However, the proposed solution does not seem to work.https://community.cisco.com/t5/email-security/custom-bounce-message/td-p/5136251If the "bounce()" action is triggered via a message filter, this text appears in the bounce message by default:"554 5.0.0 < #5.0.0 smtp; 5.x.0 - Message bounced by administrator (delivery attempts: 0)>"How can I customize the text? For example:'554 5.0.0 < #5.0.0 smtp; 5.x.0 - Message bounced by policy violation, policy #123>'I tried the following:* Created a bounce notification text resource "CustomBounce"* Created a bounce profile "CustomBounce" and selected the text resource "CustomBounce" as the notification template.* Created a message filter with the actions "bounce-profile("CustomBounce");" and "bounce();"I still get the default notification, not the text from the "CustomBounce" template.How can I ensure that bounce actions in message filters do not output the default text in the bounce, but rather a customized, meaningful message?ThanksStefan

  • Implementing IPSec over DMVPN Tunnel - ( 06-30-2025 )
  • VPN
  •                                                                            Implementing IPsec over DMVPN Tunnels Introduction Lab Topology IPsec Configuration Verification Conclusion Introduction The drawbacks of DMVPN Phase 2 are overcome by DMVPN Phase 3 implementation. DMVPN Tunnels don't offer any encryption, so the traffic passing through these tunnels are not secure. You can implement ipsec protocol over DMVPN tunnels to encrypt traffic and make them secure. While IPsec is not mandatory for a DMVPN (Dynamic Multipoint VPN) setup, it's highly recommended, especially when using the internet as the underlay network. DMVPN, in itself, provides a scalable and dynamic way to create VPN tunnels between multiple sites, but it doesn't inherently encrypt the traffic. IPsec, on the other hand, provides encryption and authentication for the data being transmitted, enhancing the security of the VPN connection. So, in this article, we will discuss how to implement IPsec over DMVPN Tunnels. To know more about DMVPN Phase 3 implementation, please go through the following the link: https://community.cisco.com/t5/vpn/dmvpn-phase-3-implementation/m-p/5302916#M299236 Lab Topology                                      Assuming that all routers are configured with Underlay and Overlay (DMVPN Phase 3) configurations. Since traffic is not encrypted by default with DMVPN, we are going to implement IPsec to encrypt the traffic passing through the DMVPN tunnels and secure them.

However, this is meant to be dynamic. Therefore, we have to specify the address 0.0.0.0 0.0.0.0, which will allow any IP address to connect as long as they know the password. DMVPNs would send traffic over mGRE tunnels, and the data is encrypted using IPSec. Now IPSec and mGRE each add their own headers, and this could lead to the packet size exceeding the MTU, or the maximum transmission unit. And this would cause fragmentation, and fragmentation is bad because it increases CPU usage on routers. So to work around this, we can use the client MSS setting in order to adjust the MTU size. Now Cisco recommends that when you set the GRE MTU on the tunnel interface, that the MTU is set to 1400. Now from this, we can then calculate the MSS. Let's say, for example, we have a GRE packet, and the maximum MTU is 1400. Now, we have the GRE header itself that's 24 bytes, then we also have the DMVPN key in the header. That's another 4 bytes. We have the IPSec header, which is 60 bytes. After the IPSec header, we have the TCP header, which is 20 bytes, and we have the IP header, which is another 20 bytes. This makes a total overhead of 128 bytes. So, if we subtract 128 from 1400, we get 1272.                                  Verification Conclusion: As we know that DMVPNs allows multi-point connectivity over the internet, but they can only do so with Cisco routers. What happens if you have a non-cisco router and you wanted to connect to a Cisco router? Well in this situation, you’d use FlexVPNs. We will discuss FlexVPNs in another article.

  • SWIM on C9300 with dual reboot - ( 06-29-2025 )
  • Cisco Catalyst Center
  • Hi Community,I've been upgrading a few Catalyst C9300L and C9300LM, from 17.08.x and 17.09.x to most recent 17.12.04 using Catalyst Center SWIM and noticed that while monitoring a switch with a continuous ping, there are two times that a switch stops replying (dual reboot) during the process as the Catalyst Center still shows progress after the second reboot, assuming final tasks are being executed.I've also performed a manual upgrade on those platforms, from same versions to 17.12.04 and noticed only one reboot.All these switches are being upgraded for the first time after being shipped, so it's their original version from factory.Both attempts, manual and SWIM, have been following Cisco Upgrade Guide recommendations.So, I'm just wondering if the dual reboot could be due to a firmware upgrade of both bootloader and OS images. Cisco says that bootloader can be upgraded before or after OS upgrade at any time but is Catalyst Center performing the bootloader first as a best practice, before upgrading OS?If so, and in case of a small maintenance window allowing only a single reboot, can we disable the option of bootloader firmware upgrade through Catalyst Center?Much appreciated for all if your inputs.

  • How to Implement Cisco Umbrella Multi-Org Console Within a Single Org - ( 06-29-2025 )
  • Umbrella Discussions
  • Hi everyone, We are working within a single company that uses multiple Cisco Umbrella tenants (for example, different departments, business units, or managed customer environments). We would like to implement the Cisco Umbrella Multi-Org Console to gain centralized visibility and management across all tenants. Could someone please clarify the following: Is it possible to implement the Multi-Org Console within a single organization managing multiple Umbrella tenants? What are the steps to activate and implement the Multi-Org Console? Are there any specific licensing or Cisco partner requirements? Does the Multi-Org Console support centralized policy management, reporting, and alerting across all tenants? If anyone has experience with this type of deployment or knows which Cisco team to contact for enabling this feature, I would greatly appreciate your input.

  • Contract not assigned to company - ( 06-26-2025 )
  • Cisco Software Discussions
  • Hi,I have Signed up for some Cisco licencing for the colaboration flex plan. with that order there is entitlements to access the associated software.after making the purchase i have actually found that the company selling the contracts are not proper cisco partners (already paid for the service now) The contract has been created however it hasnt been associated to my company properly meaning i cant access anything. I have engaged with that company and basically getting the response of "oh it should appear" "it may take some more time" I have spoken to cisco about why im unable to access my entitlements and the reason i was given is that the support contract is not assigned to the company and it needs to be assigned in order to make it work.So now i have a subscription licence that is burning through the subscription that im unable to use because 1. the vendor doesn't seem willing to help. 2. Dicker Data wont cooperate with me to fix it even when their branding is all over this. so not a good look professionally on their part especially given they are the ones who have likely made the mistake, I have asked them how to get around that and they said there is nothing i can do. So are my only options hear for real to just create a new contract again?

  • WEBUI Troubleshooting tab PCAP files - ( 06-26-2025 )
  • Switching
  • I have several tabs open to several switches and routers in the WebUI.  I'm using the troubleshooting tab to create a few PCAP files.  The issue occurs in both chrome or firefox, so I dont think it's a browser issues specifically, but some of the time I'm unable to "export to desktop".The packet capture feature (EPC) in the web interface is very intuitive and easy to use.  It's simply using the monitor capture commands but using it in the web ui allows you to download using HTTPS and in this environment that is the only option available, so it's invaluable.When it works you click the Export button and a window pops up allowing you to choose several options, default being "my desktop" which just allows you to download it directly to your PC.  When it doesn't work and you select "my desktop" the browser errors out stating it can't find the selected file.  However you can immediately select export once again and select flash: and it will create the pcap as bootflash:WebUITmp.pcap which you can then browse to in file manager and download it that way (which i found in another thread here) however it's a multi step process that's for some reason unnecessary at times.The one thing is if *it is* a browser problem, which again, multiple tabs open and on some they download fine and others I get this problem, developer tools is disabled by security so I don't have that luxury...

  • Only 6 participant videos showing at one time despite max in settings - ( 06-26-2025 )
  • Cisco Software Discussions
  • Hi all, I have been losing my mind for a couple of weeks trying to fix this issue, but using the desktop Webex tool, every meeting I have joined for the last few weeks is only showing a maximum of 6 participants in the meeting at one time. I have tried every option for the layout, including grid, and I have gone into the meeting settings through the app to change the maximum participants in the grid view to every possible number, including the maximum, but nothing changes. I've restarted my computer and the app without luck. The one thing I haven't done is delete and reinstall the app as I do not have the ability to do so on my work computer.Aside from reinstalling, any ideas on how to fix this that don't involve changing meetings layout settings? (which I have already tried a million times)
