Example
3.
Repeat
step 2
for the remote Long Distance ISL port. Both the local and
remote long distant ISL ports must be configured to the same distance level
for the connection to work. When the connection is initiated, the fabric will
reconfigure.
Level 1(L1)
An Extended Fabric license is required.
Extended Fabric port which can support up to
50 km at both 1 Gb/s and 2 Gb/s. This
mode does not support trunking with other
ports.
Level 2(L2)
An Extended Fabric license is required.
Extended Fabric port which can support up to
100 km at 1 Gb/s up to 60 km 1 Gb/s and
2 Gb/s. This mode does not support trunking
with other ports.
Level 0.5 (L0.5)
Supports up to 25 km 1 Gb/s and 2 Gb/s.
This mode was created to support 2 Gb/s up
to 10 km and uses EF principles. This mode
does not support trunking with other ports.
(Lx)
Any of L1, L2, LE, L0.5, and LD
Level D (LD)
(Dynamic long
distance
configuration)
LD mode dynamically assigns buffers based
on the link round trip timing calculation. Ports
will be disabled once the buffer pool has
been depleted. For example, if two ports are
configured at LD and each is connected at
100 km, all buffers will be utilized and the
remaining two ports will be disabled.
This mode supports up to 100 km at 1 Gb/s
and 60 km at 2 Gb/s.
