1. Verify IOMMU is enabled:
2. Restart OFED:
3. Load nvidia-peermem:
4. Verify peermem:
5. Configure NIC IPs:
6. Bring interfaces up with MTU:
7. Set ring buffers:
8. Ping cameras:
9. Run camera enumeration to verify that all 20 cameras are visible.
10. Confirm IGMP snooping is disabled on VLAN 10 and VLAN 20.
11. Start
12. Verify that the host is the PTP grandmaster and all cameras have PTP lock across both VLANs before sending an eTrigger pulse.
cat /proc/cmdline | grep iommu2. Restart OFED:
sudo /etc/init.d/openibd restart3. Load nvidia-peermem:
sudo modprobe nvidia-peermem4. Verify peermem:
lsmod | grep nvidia_peermem5. Configure NIC IPs:
sudo ip addr add 172.16.10.1/24 dev enp1s0f0np0 && sudo ip addr add 172.16.20.1/24 dev enp1s0f1np16. Bring interfaces up with MTU:
sudo ip link set enp1s0f0np0 up mtu 9000 && sudo ip link set enp1s0f1np1 up mtu 90007. Set ring buffers:
sudo ethtool -G enp1s0f0np0 rx 8192 tx 8192 && sudo ethtool -G enp1s0f1np1 rx 8192 tx 81928. Ping cameras:
ping 172.16.10.11 && ping 172.16.20.119. Run camera enumeration to verify that all 20 cameras are visible.
10. Confirm IGMP snooping is disabled on VLAN 10 and VLAN 20.
11. Start
ptp4l with the updated priorities, then start phc2sys -a -r in a second terminal.12. Verify that the host is the PTP grandmaster and all cameras have PTP lock across both VLANs before sending an eTrigger pulse.
