Description: This attribute indicates the current state of the LEC. Note that ifOperStatus is up only when interfaceState is operational. - initialState: Some parameters (such as addresses and ELAN name) are known to the LEC. - lecsConnect: LEC establishes Configuration Direct VCC to LECS. Manually-configured LECs skip this state. - configure: LEC discovers LES. - join: LEC establishes control connections to LES. LEC is assigned unique LECID and knows all ELAN parameters. - initialRegistration: LEC may register additional MAC addresses with LES. This is in addition to the single MAC address registered during Join phase. - busConnect: LEC issues LE_ARP to locate the BUS and sets up the connection. The BUS then establishes the Multicast Forward VCC to the LEC. - operational: LEC is operational and can forward data traffic.
