 For a blade server that lacks support of bonding, the port channel mode that results in “route based on originating virtual port” on the VMware VDS is MAC Pinning-Physical-NIC-load (Option B). This mode ensures that the virtual machine traffic is distributed across the available uplinks based on the MAC address of the originating virtual port1.

In a Cisco ACI fabric, Spanning Tree Protocol (STP) Bridge Protocol Data Units (BPDUs) that are generated by an external switch, such as Switch2 in this scenario, are indeed forwarded across the fabric. This allows externally connected switches to maintain a loop-free topology. While Cisco ACI does not participate in STP as it uses its own protocols and mechanisms for loop prevention within the fabric, it will forward STP BPDUs across End Point Groups (EPGs) on which they are received1. This ensures that the connected external switches can still use STP for their loop prevention mechanisms.

To securely back up the current Cisco ACI configuration to a remote location with encryption and authentication, and ensure that sensitive information is not exported, the following steps should be taken:

Create a Remote Location: Define a remote location where the backup will be stored. This involves specifying the hostname or IP address of the remote server and selecting the protocol (SCP/FTP/SFTP) to be used1.

Create a Configuration Export Policy: Set up an export policy that defines the format (XML/JSON) and the destination for the backup. This policy will also include the schedule for the backup to run once per day1.

Configure Global AES Encryption: To ensure that the backup is encrypted, configure the Global AES Encryption setting. This will allow for hashed secure properties, such as passwords and certificates, to be exported in an encrypted form. It’s important to configure a passphrase that is at least 16 characters long for the encryption1.

Schedule the Backup Job: Use the scheduler to set up the backup job to run once per day. This ensures that the backup process is automated and adheres to the customer’s security policy1.

Exclude Sensitive Information: To comply with the security policy that mandates sensitive information not be exported, ensure that the configuration export policy is set to exclude secure fields unless encryption is enabled1.
