I (think) I am following the correct NCL syntax here...but.. ncl> create node 0 routing circuit csmacd-0 type = csma-cd ncl> set node 0 routing circuit csmacd-0 data link entity csma-cd Here should be the data link entity defined completely as is done below. It would be more clear if you use another name for the routing circuit entity than is used for the csma-cd station entity. ncl> set node 0 routing circuit csmacd-0 enable phaseiv address true ncl> enable node 0 routing circuit csmacd-0 Node 0 Routing Circuit csmacd-0 AT 2013-02-13-13:05:26.514-05:00I----- FAILED IN DIRECTIVE: Enable DUE TO: Error specific to this entity's class REASON: Open Port Failed Description: The Open Port call to the specified Data Link failed Any ideas what i'm doing wrong? ____ This is the script: create csma-cd create csma-cd station csmacd-1 communication port tu0 enable csma-cd station csmacd-1 create routing circuit circuit-1 type csma-cd # # The following command sets the inactive area address, which is used # to enable transmission and receipt of ISO 8473 Inactive Subset PDUs, # also known as Null Internet.
