Hi,

     Max is 30Km using ER optics and 10Km for LR.

EDIT - Extract is from Network OS Administrator Guide 3.0.1 I would assume it is the same for 3.0.0. Confirmed up to 30Km for 3.0.0 as well.

Long distance ISL guidelines and restrictions

Consider the following when configuring long distance ISL:

Long distance ISL is only supported on 10G interfaces.

Edge ports can not be configured with DCB maps.

Edge ports and port groups with long distance links can not use the fcoeport default command.

A maximum of three PFCs can be supported on a long distance ISL configured platform. By default, PFC is enabled by class 3 and 7.

All the ports on the platform are rebooted when configuring a port for long-distance.

For 2Km, 5Km, 10Km long-distance, use Brocade-supported long range (LR) optics for direct connectivity.

For 30Km long-distance, use Brocade-supported extended range (ER) optics for direct connectivity.

To configure a long distance ISL port, use the long-distance-isl command in interface configuration mode. Refer to the Network OS Command Reference for complete details. The following example sets port 1/0/2 to support long distance ISL up to 30Km.

Example

switch(conf-if-te-1/0/2)# long-distance-isl 30000


Thanks

Michael.
