2.2.7 Provisioning Subnetwork Connections
The three modes supported for SNC provisioning on Ethernet equipment are:
• Single-card mode—E-series cards; VLANs can be associated during creation.
• Multicard mode—E-series cards; VLANs can be associated during creation.
• Linear-card mode—E-series, G-series, and ML-series cards.
To obtain available source and destination FTPs for SNC provisioning, use the following methods:
• managedElementManager::ManagedElementManager_I:: getAllSrcFTPsForSNCProvisioning
• managedElementManager::ManagedElementManager_I:: getAllDestFTPsForSNCProvisioning
2.2.7.2.1 Single-Card Mode and Multicard Mode
By default, all E-series cards are in the multicard mode EtherSwitch group. Each node has only one
multicard mode EtherSwitch group; the group exists even if the node has no Ethernet cards. A
single-card EtherSwitch group can exist only if a node has at least one Ethernet card.
• To create SNCs in multicard mode, both aEnd and zEnd must be in the multicard EtherSwitch group.
• To create SNCs in single-card mode, one end can be an OC-n CTP. You must create a bidirectional
SNC.
The following table shows the maximum bandwidth allowed for single- and multicard EtherSwitches.
2.2.7.2.2 Linear-Card Mode
You can apply linear-card mode SNC provisioning to all types of Ethernet cards. One end of the SNC
must be an FTP; the other end can be a CTP on any OC-n port, or an FTP. The FTPs must use linear-mode
naming conventions.
Only single source and single destination are supported for the SNC creation, and the SNC must be
bidirectional.
For E-series and G-series cards, the port number in the FTP name is the number of the front Ethernet
port. For ML-series cards, the port number is the number of the virtual back-end port.
