b. From the label set, remove the two appropriate color-coded switch and
port labels. Wrap one label around one end of the cable and wrap the
second label around the other end of the cable.
c. Line up the keyed cable connector on one end of the cable with the
notch in the GBIC of the appropriate port and switch.

3. Check the fabric for port or ISL issues.
a. From a computer workstation, log on with administrative privileges
by Telnet to one of the switches in the group.
b. Enter the following at the Telnet prompt:
islTopoShow
This command provides general information about all the switches in
the group. The results of this command are valid as soon as the fabric
stabilizes (the port LEDs stop flickering) after the switches are
reconnected. If there are any problems, the Status column in the
islTopoShow
display indicates an error condition.
4. Check each switch for port or ISL issues.
a. From a computer workstation, log on with administrative privileges
by Telnet to one of the switches in the group.
b. Enter the following at the Telnet prompt:
islTopoCheck
The
islTopoCheck
command provides detailed information about
the local switch (the switch currently accessed by Telnet). If there are
any problems, the Status column indicates an error condition. This
command can require 60 seconds or more to provide information,
depending upon the error rate specified in the threshold profile.
