Fabric OS 6.1.x administrator guide 371
The following example shows traffic flowing through a trunking group (ports 5, 6, and 7). After port 6 fails,
traffic is redistributed over the remaining two links in the group, ports 5 and 7:
switch:admin> portperfshow
01234567 Total
--------------------------------------------------------------------
00000145m144m145m 434
00000144m143m144m 431
00000162m0162m 324
Enabling and disabling ISL Trunking
You can enable or disable ISL Trunking for a single port or for an entire switch.When you execute the
commands portCfgTrunkPort or switchCfgTrunk to update the trunking configuration, the ports
for which the configuration applies are disabled and re-enabled with the new trunk configuration. As a
result, traffic through those ports could be disrupted.
IMPORTANT: Trunking is performed based on QoS configuration on the master and the slave ports. That
is, in a given trunk group, if there are some ports with QoS enabled and some with QoS disabled, they
would form two different trunks, one with QoS enabled and the other with QoS disabled. For more
information, see ”QoS zones” on page 306.
To enable or disable ISL Trunking on one port:
1. Connect to the switch and log in as admin.
2. Issue the portCfgTrunkPort command:
portcfgtrunkport [slotnumber/]portnumber mode
where:
• slotnumber specifies the number of the slot in which the port blade containing the port is located.
This operand is required only for Directors.
• portnumber specifies the number of the port on which you want to enable or disable trunking.
• mode enables (1) or disables (0) trunking on the specified port.
The following example enables trunking on slot 1, port 3:
switch:admin> portcfgtrunkport 1/3 1
done.
switch:admin>
To enable or disable ISL Trunking for all of the ports on a switch:
1. Connect to the switch and log in as admin.
2. Issue the switchCfgTrunk command. The format is:
switchcfgtrunk mode
Mode 1 enables and mode 0 disables ISL Trunking for all ports on the switch.
The following example enables trunking all ports in the switch:
switch:admin> switchcfgtrunk 1
Committing configuration...done.
switch:admin>
