Trunking Over Extended Fabrics; Trunking Distances; Trunking Support For San Switch 4/32, 4/32B And 4/64 San Switch (Condor Asic) - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

Use the trunkShow command to display the following information about ISL Trunking groups:
Trunking Group Number Displays each trunking group on a switch. All the ports that are
Port-to-port connections, Displays the port-to-port trunking connections.

Domain
Deskew
Master
To display trunking information:
1. Connect to the switch and log in as admin.
2. Issue the trunkShow command:
This example shows three trunking groups (1, 2, and 3); ports 1, 4, and 14 are masters:
switch:admin> trunkshow
1: 1 ->
0 ->
2: 4 ->
5 ->
7 ->
6 ->
3:14 -> 14
15 -> 15

Trunking over Extended Fabrics

In addition to the criteria listed in
for trunking over Extended Fabrics:
• ISL Trunking over Extended Fabrics is supported on switches running Fabric OS 4.4.0 and 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 fabric. When
you issue the portCfgLongDistance --vc_translation_link_init command, specify 1 to
activate long-distance link initialization sequence; specify 0 to deactivate this mode. If you run the
command without specifying a value, 1 is assigned automatically for the long-distance link in VC_RDY
flow control; otherwise, 0 is assigned. For a long-distance link not configured for ISL R_RDY mode, this
parameter must be set to 1; otherwise, it must be reset to 0.
