Description: The gpon port is similiar to VCLs in ATM. Data is transferred between OLT and ONU via ports. This profile is dynamically created during CLI bridge-add, host-add, interface-add commands but must be explicitly created during SNMP operation.

GEM ports can be created using a supplied I/F index value or using the next available I/F index value. Since the GEM Port is a virtual device, ZMS prefers to supply the I/F index value because ZMS cannot lookup the newly created GEM port using shelf/slot/olt/port indexing ( virual devices do not support these values).

How to create a GEM port using next available I/F Index value, using a single SNMP packet with multiple var-binds:

1. Do an SNMP-Next of the object ifIndexNext to determine the I/F index value of the new GEM port. The SNMP-Next will not result in the auto-increment of ifIndexNext.

2. Issue single SNMP set command containing the following: zhoneGponPortConfigRowStatus.1 = create zhoneGponPortConfigRowShelf.1 = 1 zhoneGponPortConfigRowSlot.1 = GEM port slot zhoneGponPortConfigRowOlt.1 = GEM port OLT zhoneGponPortConfigRowPort.1 = GEM Port ID value zhoneGponPortConfigRowTrafficProfile.1 = traffic profile

The GEM port will be created using the next available ifIndex.

How to create a GEM port with a specified I/F index value, using a single SNMP packet with multiple var-binds:

1. Do an SNMP-Get of the object ifIndexNext to determine the next available I/F index value. The SNMP-Get will result in the auto-increment of ifIndexNext.

2. Issue single SNMP set command containing the following: zhoneGponPortConfigRowStatus.aaa = create zhoneGponPortConfigRowShelf.aaa = 1 zhoneGponPortConfigRowSlot.aaa = GEM port slot zhoneGponPortConfigRowOlt.aaa = GEM port OLT zhoneGponPortConfigRowPort.aaa = GEM Port ID value zhoneGponPortConfigRowTrafficProfile.aaa = traffic profile

where aaa is the I/F index value collected in step 1.

A GEM Port cannot be created if an I/F translate record already exists using the supplied I/F index value.

How to delete a GEM port using a single SNMP packet:

1. Determine I/F index of GEM port config profile (aaa)

2. Issue single SNMP set command containing the following: zhoneGponPortConfigRowStatus.aaa = destroy

Special Notes:

1. The deletion of a GEM port will be prevented if the GEM port supports bridges, interfaces, etc.

2. The GEM port ID value determines the GEM port ONU.
