Limitations Since the total number of frame buffers is limited in quad, when one
of the ports in the quad is configured as a long distance port, all
remaining ports must be level zero ports only (that is, none of the
remaining ports in the quad can be a long distance port). Further
more, if one port is configured as a level 2 long distance po rt, none of
the remaining ports in the quad can be used as an E_Port.
A quad is defined as a group of four adjacent ports that share a
common pool of frame buffers. Port 0-3 belong to a quad, so do port
4-7, and so on.
Certain buffers are dedicated for each port, and others are shared among the
ports. In Extended Fabric mode, one port is given an increase of dedicated
buffers from this pool. Refer to the EMC Connectrix Departmental Switch
DS-32B2 and Enterprise Director ED-12000B Extended Fabric User Guide for
more information on limitations in p ort configurations.
Example The following example is for a 100 km link on a port in a v4.0 switch:
switch:admin> portCfgLongDistance 2/3, L2
done.
The following example is for a 100km link on a port in a v4.0 switch
with long distance link initialization protocol enabled:
switch:admin> portCfgLongDistance 2/3 L2 1
done.
