364 Administering ISL Trunking
The following example sets the speed for all ports on the switch to eight Gbps:
switch:admin> switchcfgspeed 8
Committing configuration...done.
The following example sets the speed for all ports on the switch to autonegotiate:
switch:admin> switchcfgspeed 0
Committing configuration...done.
Displaying trunking information
The trunkShow command offers an efficient means of listing out all the trunks and members of a trunk.
You can easily discover the peer ports for disabling a port, disconnecting or adding additional members.
Viewing trunks is also useful for when you want to ensure that trunks are formed correctly.
Use the trunkShow command to display the following information about ISL Trunking groups::
To display trunking information:
1. Connect to the switch and log in as admin.
2. Enter 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 -> 1 10:00:00:60:69:04:10:83 deskew 16 Master
0 -> 0 10:00:00:60:69:04:10:83 deskew 15
2: 4 -> 4 10:00:00:60:69:04:01:94 deskew 16 Master
5 -> 5 10:00:00:60:69:04:01:94 deskew 15
7 -> 7 10:00:00:60:69:04:01:94 deskew 17
6 -> 6 10:00:00:60:69:04:01:94 deskew 16
3:14 -> 14 10:00:00:60:69:04:10:83 deskew 16 Master
15 -> 15 10:00:00:60:69:04:10:83 deskew 15
Trunking Group Number Displays each trunking group on a switch. All the ports that are
part of this trunking group are displayed.
Port-to-port connections, Displays the port-to-port trunking connections.
WWN Displays the WWN of the connected port.
Domain
CAUTION: Displays the domain IDs of the switches
directly connected to the physical
ports.
Deskew 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 Displays whether this trunking port connection is the master port
connection
for the trunking group.
