What is the difference between stitched and unstitched Ethernet? What are the advantages or disadvantages of one versus the other?
A. Stitched, also known as Multicard EtherSwitch, allows you to provision two or more Ethernet cards in the same chassis to act as a single Layer 2 (L2) switch. Multi-Card mode limits circuit size to STS6c, because this mode reserves the remaining STS6c of bandwidth available to the card for a “stitch” to other E-Series cards in the Ethergroup. This limitation does not allow you to fully utilize your bandwidth. However, all installed Ethernet cards in an Ethergroup can transmit to and receive from any provisioned Ethernet circuit and VLAN(s). The most common application for this mode of operation is the use of Shared Packet Rings, which utilize Spanning Tree Protocol rather than SONET switching to provide redundancy. This makes more efficient use of SONET bandwidth as the circuits are created unprotected. Unstitched, also known as a Singlecard EtherSwitch, allows each Ethernet card to remain a single switching entity. Unstitched circuits alleviate the limitation of STS-6. They allow th
