To configure a virtual port using the navigation tree
Steps
| 1  | On the Equipment navigation tree, expand NE→Shelf→Card Slot→Daughter Card Slot, right-click on an access/hybrid Ethernet port and choose Properties. The Port (Edit) form opens. This applies to ports on the IOM3 and IMM on the 7750 SR, 7750 SR-c4 and 7450 ESS. | 
| 2  | Click on the Egress Scheduling Virtual Port tab. | 
| 3  | Click Create. The Egress Scheduling Virtual Port (Create) form opens. | 
| 4  | Configure the required general parameters. | 
| 5  | Select a port scheduler policy in the Port Scheduler Policy panel. You cannot select a port scheduler policy for the virtual port if you have already selected a port scheduler policy for the associated channel. Likewise, selecting a port scheduler policy for the virtual port prevents you from selecting a port scheduler policy for the associated channel. | 
| 6  | Select a scheduler policy in the Scheduler Policy panel. | 
| 7  | If you did not select a scheduler policy in Step 6 , configure the parameters in the Aggregate Rate Limit panel. The Limit Unused Bandwidth parameter is only available on access ports and on SONET channels when an ATM MDA is used. | 
| 8  | Configure the Status parameter in the Egress Rate Modify panel. | 
| 9  | Configure the parameters in the Hardware Aggregate Shaper Scheduler panel. | 
| 10  | Click on the Host Matching tab. | 
| 11  | Click Create. The Host Matching (Create) form opens. | 
| 12  | Configure the Destination String parameter. | 
| 13  | Save your changes and close the forms. End of steps |
