1. Enter the show running-config interface command to determine which interfaces have trunking
enabled.
switch# show running-config interface
interface Management 66/0
no ip address dhcp
ip address 10.24.81.66/20
ip route 0.0.0.0/0 10.24.80.1
ipv6 address ""
no ipv6 address autoconfig
!
interface TenGigabitEthernet 66/0/1
fabric isl enable
fabric trunk enable
no shutdown
!
interface TenGigabitEthernet 66/0/2
fabric isl enable
fabric trunk enable
no shutdown
!
interface TenGigabitEthernet 66/0/3
fabric isl enable
fabric trunk enable
no shutdown

2. Verify the status of the ISL port and link.
a)
Enter the show fabric isl command to verify whether the ISL is up.
b)
Enter the show fabric islports command to examine the status of each port.
on page 686 for details and corrective action.
3. Enter the show interface command for each trunk link and examine the rate information to check
for an equal distribution of traffic on the interfaces in the trunk. The rate information is shown
underlined in the following example.
switch# show interface tengigabitethernet 66/0/12
TenGigabitEthernet 66/0/12 is up, line protocol is down (link protocol down)

4. Having found a trunk member that carries no traffic while the other trunk members are busy, from
the same show interface command output, check the interface status, configuration, and error
statistics.
