Cisco Firepower Forbidden- you don’t have permission to access

After re-image FPR2110 from FTD to ASA9.8.2, the chassis (FXOS) mgmt interface UI become unaccesible giving the following error “Forbidden- you don’t have permission to access / on this server”.

In a nutshell, i could access FXOS via SSH and ASA (SSH & HTTPS) but the FXOS Chassis Management was broken. After spend some time, the only way to get this sorted was upgrade for the version 9.9.x

After upgrade, everything was working again.

Juniper Cross-Track Recertification for Associate-Level Exams

Do you have an associate-level exam that is coming up for renewal? Rather than retaking the same exam, you can now recertify your certification by passing another associate-level exam.

On September 21, the Juniper Networks Certification Program (JNCP) updated the recertification policies to allow for cross-track recertification for all associate-level exams. If, for example, your JNCIA-Junos certification is coming up for renewal, consider attempting the JNCDA, the JNCIA-Cloud, or the new JNCIA-DevOps certification exam instead. If you pass, not only will you have earned a new certification, but you will have also recertified an existing one.

Plus, you’ll be on your way to earning our new JNCIAx3 or JNCIAx4 multi-certification badges.

Learn more on the JNCP Recertification webpage.

Dell Networking OS10 using GNS3

Dell EMC Networking OS10 combines the best of Linux, open computing, and networking to advance open networking disaggregation. OS10 is a transformational software platform which provides networking hardware abstraction through a common set of APIs.
You can enable consistency across compute and network resources for your system operator (sysops) groups that require server-like manageability, as well as leverage your existing network con€guration.
You can simulate OS10 devices using OS10 VM appliances. The OS10 VM appliances execute the same software deployed on OS10-enabled hardware devices, with the exception of the hardware abstraction layer. The OS10 VM hardware abstraction layer simulates hardware devices in a VM environment.

All CLI commands as well as RESTCONF and SNMP interfaces are available in the OS10 simulation environment. You can build sandbox environments to learn open networking concepts, and prototype network operations and scripts risk-free.

OS10 simulation features

All OS10 CLI commands and north-bound interfaces (RESTCONF, SNMP) are available including:

  • System management (SSH, AAA, DHCP, and so on)
  • Management port

L3 data plane and control plane (using Linux functionality)

Partial support for L2 data plane and control plane (using Linux functionality):

  • LACP
  • VLAN
  • LLDP
  • VLT

OS10 feature limitations

  • No ACL or QoS support (NPU is not available) — ACL and QoS CLI commands are available (but have no effect on trafc)
  • Limited L2 functionality (NPU is not available on simulator) — no spanning-tree control plane functionality
  • No breakout mode for simulated ports
  • Defaults to S6000-ON hardware platform simulation

Requirements

  • Workstation or laptop with 16 GB RAM or larger recommended
  • 64-bit x86 CPU with 2 GHz or faster core speed (dual-core or larger recommended)
  • SDD with 64 GB available space
  • Virtualization environment — you can use either Windows, Linux, or VMware ESXi as a host system for the GNS3 Server VM environment
  • VMware ESXi server recommended for large network simulation
