Guidelines and restrictions for standard-distance Metro VCS
Consider the following when configuring Metro VCS with standard-distance ISLs:
• Only two data-center and three data-center topologies are supported.
• A maximum of two nodes are supported for each site, which provides node redundancy. If more-
complex local designs are required, a local VCS sub-fabric design must be used.
• Only standard Ethernet services are supported. DCB and FCoE are not supported.
• Brocade trunking with up to 80-G (8x10-G) links is supported.
• There are no additional limitations on the supported overall number of MAC addresses.
Metro VCS and distributed Ethernet vLAGs
Outside of Metro distances, and whenever bit transparency may be a problem, edge-to-edge
interconnected fabrics using 10-G vLAG over multiple standard Ethernet links can be used. This
allows you to connect separate Ethernet fabrics that can be located in different data centers, even if
the distance between those locations is more than 30 km. This is currently supported for distances up
to 100 km.
Metro VCS over a long-distance fabric
As illustrated below, one side can be a Metro VCS over a long-distance fabric.
