The most likely reason the sa-web-01 VM dvfilter name is missing from the command output is that the sa-web-01 VM is powered off on the ESXi host. The dvfilter name is associated with the VM when it is powered on, and is removed when the VM is powered off. Therefore, if the VM is powered off, then the dvfilter name will not be visible in the command output. Other possible reasons could be that the ESXi host has the firewall turned off, the ESXi host has 5SH disabled, or that the sa-web-01 VM has no firewall rules configured.

The NSX-T IDS/IPS updates are provided through VMware's cloud-based internet service at two different intervals: daily periodic updates, and off-schedule for 0-day updates. Daily periodic updates are provided on a daily basis to ensure the latest threat signature files. Off-schedule updates are provided as needed when a 0-day threat is identified, allowing customers to have the most up-to-date protection from the latest threats.

East-West service insertion refers to the ability to insert security services, such as firewall and intrusion detection and prevention, between virtual machines (VMs) that are communicating within the same logical network.

One of the insertion points for East-West service insertion is the virtual network interface card (vNIC) of the guest VM. The vNIC is the virtual representation of a physical NIC on a VM, and it connects the VM to the virtual network. By inserting security services at the vNIC level, traffic between VMs can be inspected and secured before it reaches the virtual switch.
