Displaying trunking information
Use the
trunkshow
command to display the following information about ISL Trunking groups:
• Number identifier.
• Port-to-port connections, listed in the format
local port number -> remote port number
.
• WWNs of the remote switches.
• Deskew values (the time difference, in nanoseconds divided by 10, for traffic to travel over each ISL as
compared to the shortest ISL in the group). The system automatically sets the minimum deskew value of
the shortest ISL to 15.
• Master ports.
To display trunking information:
1. Connect to the switch and log in as admin.
2. Issue the
trunkshow
command.
The following example shows three trunking groups (1, 2, and 3); ports 1, 4, and 14 are masters:
Trunking over extended fabrics
In addition to the criteria listed in ” Standard trunking criteria ” on page 113, observe the following
criteria for trunking over extended fabrics:
• ISL Trunking over extended fabrics is supported on switches running Fabric OS v3.2.0 (or later) or
v4.4.x (or later).
• Extended Fabrics and ISL Trunking licenses are required on all participating switches.
• The
vc_translation_link_init
parameter must be set the same on all ports in an extended
trunk. (For details on this parameter, see page 110 .)
