The value of tmnxEthTunnelLEMbrThreshold specifies the threshold for
the Ethernet Tunnel Group.
When a physical port member state changes and the number of operational
physical port members is less than or equal to
tmnxEthTunnelLEMbrThreshold, the Ethernet Tunnel Group is set
operationally down.
When the number of operational physical members become greater than
tmnxEthTunnelLEMbrThreshold, the Ethernet Tunnel Group is set
operationally up
The value of zero specifies to bring the Ethernet Tunnel Group
operationally down only when all members are operationally down, and
bring the Ethernet Tunnel Group operationally up when at least one
member is operationally up.
