The NVR supports port trunking which combines two Ethernet interfaces into one to
increase the bandwidth and offers load balancing and fault tolerance (also known as
failover). Load balancing is a feature which distributes the workload evenly across
two Ethernet interfaces for higher redundancy. Failover is the capability to switch
over to a standby network interface (also known as the slave interface) when the
primary network interface (also known as the master interface) does not correspond
correctly to maintain high availability.
To use port trunking on the NVR, make sure at least two LAN ports of the NVR have
been connected to the same switch and the settings described in sections (i) and (ii)
have been configured.
Follow the steps below to configure port trunking on the NVR:
1
. Click “Port Trunking”.
2.Select the network interfaces for a trunking group (Ethernet 1+2, Ethernet 3+4,
Ethernet 5+6, or Ethernet 7+8). Choose a port trunking mode from the drop-down
menu. The default option is Active Backup (Failover).
