snMetroRingPort1

brcdIp.1.1.3.29.2.1.1.7

Syntax: InterfaceIndex

Read-write

The ifIndex value of port 1 to configure into the metro ring.

snMetroRingPort2

brcdIp.1.1.3.29.2.1.1.8

Syntax: InterfaceIndex

Read-write

The ifIndex value of port 2 to configure into the metro ring.

snMetroRingName

Read-write

The description of the metro ring.

snMetroRingRowStatus

brcdIp.1.1.3.29.2.1.1.10

Syntax: Integer

Read-write
