7210 SAS-MXP, R6, R12, S, SX, T BASIC SYSTEM
CONFIGURATION GUIDE RELEASE 22.9.R1
Boot options
Platforms
Supported on all 7210 SAS platforms as described in this document, including those operating in access-
uplink mode
Description
This command configures whether the system will preserve system indexes when a save command is
executed. During a subsequent boot, the index file is read along with the configuration file. As a result, a
number of system indexes are preserved between reboots, including the interface index and others. This
reduces resynchronizations of the Network Management System (NMS) with the affected network element.
In the event that persist is on and the reboot with the appropriate index file fails, SNMP is operationally
shut down to prevent the management system from accessing and possibly synchronizing with a partially
booted or incomplete network element. Use the config>system>snmp>no shutdown command to enable
SNMP access.
If persist is enabled and the admin>save file-url command is executed with an FTP path used as the
file-url parameter, two FTP sessions simultaneously open to the FTP server. The FTP server must be
configured to allow multiple sessions from the same login; otherwise, the configuration and index files will
not be saved correctly.
Note:
•
Persistency files (.ndx) are saved on the same disk as the configuration files and the image
files.
• When an operator sets the location for the persistency file, the system will checks to ensure
that the disk has enough free space. If this there is not enough free space, persistency does
not become active and a trap is generated. In this case, the operator must free adequate
disk space. Until disk space is freed, the system performs a space availability check every 30
seconds. As soon as the space is available, persistency will become active on the next (30
second) check.
