Cisco Nexus - Switch Fabric Module


What is a switch fabric module?





Fabric module connects the supervisor engine and line cards of the switch





Fabric Module Types





  1. Fabric Module - 1 - Generation 1 (provides 46 Gbps of backplane capacity)
  2. Fabric Module - 2 - Generation 2 (provides 110 Gbps of backplane capacity)
  3. Fabric Module - 3 - Generation 3 (provides 2.8 Tbps of backplane capacity)




What do the above numbers indicate?





The original M1 series I/O modules eg. N7K-M132XP-12 have 80 Gbps of capacity per slot. So, two Generation 1 fabric modules would be required (2*46Gbps = 92 Gbps) for providing sufficient fabric capacity for the M1 series 10GE line card. Ordinarily, Cisco would recommend using 3 fabric modules in this case, for redundancy purposes, since one fabric module going down would translate to reduced capacity / backplane in the production environment. This implies, the overall fabric module capacity should exceed the line card capacity.





Hardware specific details





  • Nexus 7004 has no fabric modules
  • Nexus 7000 series supports 5 fabric modules
  • Nexus 7700 series supports 6 fabric modules

MITRE ATT&CK - Kerberos Vulnerabilities and Security

From the previous post, the summary of Kerberos authentication process is as below: For the initial authentication, the user’s client machine sends a request to the KDC  Authentication Service (AS) . The request includes details like the user’s username, and the date and time. All information except the username is encrypted using the hash of the user’s password. The KDC AS uses the username to look up its copy of the user’s password hash and uses it to decrypt the rest of the request. If the decryption is successful, that means the client used the correct password hash and the user has successfully authenticated. Once the user is authenticated, the KDC AS sends the user’s client a  ticket granting ticket   (TGT) . The TGT includes a unique session key and a timestamp that specifies how long that session is valid (normally 8 or 10 hours). Importantly, before sending the TGT, the KDC encrypts it using the password hash for a special account, the  KRBTGT account. ...

Checkpoint - Exporting Objects in CSV format

Be it a Network Operations Manager, Security Architect or a Security Auditor, the people up the hierarchy always harangue the Security Engineers to compile the list of firewall objects or rules or policies or the traffic statistics and so on.. This can turn out to be quite hectic especially if there are no built in features to systematically provide the output in a "layman-readable" format. Come, Checkpoint's "Object Explorer..."  which not only provides the output in the "layman-readable" format, but also provides in-built filtering mechanisms, thereby ensuring that the Security Engineer doesn't have to rely on Google for building his scarce Microsoft Excel data filtering skills. The following screenshots will show how easy it is, with Checkpoint R80.10 to generate the firewall configuration inventory. On the SmartConsole Unified Portal, navigate to Menu >> Open Object Explorer... Select the Categories you wish to see in your output: Click o...
