Extended link buffer allocation overview
14
DRAFT: BROCADE CONFIDENTIAL
For an LD-mode link, the desired distance is used as the upper limit of the link distance to
calculate buffer availability for other ports in the same port group. If the measured distance is
more than the desired distance, the desired distance is used to allocate the buffers. In this
case, the port operates in degraded mode instead being disabled due to insufficient buffers.
For an LS-mode link, the actual distance is not measured; instead the desired distance is used
to calculate the buffers required for the port.
• Long Distance— Table 16 describes the long-distance settings and identifies which settings
require a Brocade Extended Fabrics license.
