Cannot execute
commands from any
switch in the fabric.
All FCS switches have
failed but secure mode is
still enabled, preventing
access to fabric.
Type the secModeEnable command from the switch that you want
to become the new primary FCS switch, and specify the FCS
switches.
Note: Specify adequate backup FCS switches to prevent a
recurrence of this problem.
Cannot access some or
all switches in the fabric.
The MAC policies are
restricting access.
Note: An empty MAC
policy blocks all access
through that management
channel.
Use a serial cable to connect to the primary FCS switch; then, enter
the secPolicyShow command to review the MAC policies.
Modify policies as necessary by either entering valid entries or
deleting the empty policies.
Cannot access primary
FCS switch by any
management method.
Primary FCS switch has
failed or lost all
connections.
Log in to the backup FCS switch that you want to become the new
primary FCS switch and enter the secFCSFailover command to
reassign the primary FCS role to a backup FCS switch.
If no backup FCS switches are available, enter the
secModeEnable command to specify a new primary FCS switch.
Specify adequate backup FCS switches to prevent a recurrence.
Troubleshoot the previous primary FCS switch as required.
Cannot access a device
or switch port listed in
the SCC or in a DCC
policy.
Switch port might be
disabled.
Type the switchShow command. If the port in question is disabled,
enter the portEnable command. If the switch port still cannot be
accessed, enter the portEnable command for the port on the other
switch.
One or more CLI
sessions is automatically
logged out.
Password might have been
modified for login account
in use, the secModeEnable
command might have been
issued, or switches might
have changed switch roles
(primary to backup, backup
to primary, and so forth).
Try closing and reopening CLI session.
On chassis-based
platforms, status
messages from any
logical switch are
broadcast to the serial
console and telnet
sessions on all other
logical switches.
The status messages from
any logical switch are
normally broadcast to the
serial console and telnet
sessions on all logical
switches.
All broadcast messages display the switch instance. Messages that
originate from a switch instance other than the one to which the
telnet session is logged in can be ignored.
CLI session freezes or
cannot be established
after secure mode is
enabled.
CP failed over and network
routing cache(s) require
updating.
Try closing and reopening CLI session. If this fails, request that
your LAN administrator refresh the network router cache(s).
