3.2 Preparing to update
Ta
ble 3-1 shows the conditions required for updating the software. Make sure these conditions are
met before updating the software.
Table 3-1 Required conditions before update
No. Update operation Conditions Procedure
1 The Switch must be accessible from a remote
terminal, such as a PC.
Connect a remote terminal to the network so that IP
communication between the terminal and the
Switch is possible.
2 FTP client software must be running on the
remote terminal, and files must be able to be
written to the Switch by the put statement.
Obtain FTP client software and install it on the
remote terminal. In Windows, the FTP software
provided with the OS can be used.
3 The Switch must be configured in the
configuration to communicate with remote
terminals via FTP.
Set
ftp-server in the configuration. If access
list information exists in
line vty mode, the
Switch must be set to allow access from remote
terminals.
4
Conditions required
for transferring the
update file
Available capacity on the internal flash memory
must be sufficient to receive the transferred
update file.
Use the show system command to confirm that
the free capacity of the user area in the internal
flash memory of both BCU 1 and BCU 2 for an
AX6700S series switch, CSU 1 and CSU 2 for an
AX6600S series switch, or MSU 1 and MSU 2 for
an AX6300S series switch is larger than the
update file by 1,000 KB or more.
If the update file cannot be transferred because the
internal flash memory capacity is insufficient, see
3.3 Actions to be taken if there is insufficient
free space in the internal flash memory
.
5 Login to the Switch that will be updated must be
possible from a remote terminal or a console.
For login from a remote terminal via Telnet, the
Switch must be set to support the Telnet
functionality.
(Use the
line vty command to make this in the
configuration.)
6 The user must have administrator-level
permissions (enable).
To execute the
ppupdate command, use the
enable command to become an administrator.
7
Conditions required
for executing the
ppupdate
command
In a BCU, CSU, or MSU redundant
configuration
, the license information between
the active and standby systems must match.
If the license information does not match, use the
synchronize command to synchronize the
information, and then use the reload command
to restart the standby system.
3.3 Actions to be taken if there is insufficient free space in the internal flash memory
 Use t
he rm command to delete all files in /usr/var/core/.
 Execute the erase protocol-dump unicast all command.
 Execute the squeeze command.
 Reduce the number of user files saved in the user area.
