Using a script to configure a Stinger unit
To downgrade to an earlier software version after enabling extended profiling, follow
these steps:
1
Save the configuration to another system. For example:
admin> save network 10.10.10.10 cfgsave
2 Reformat NVRAM.
admin> nvram -f
When you clear NVRAM, the system loses its IP addresses.
3 After reformatting NVRAM, perform the following steps to regain a minimal IP
configuration:
– In the IP-Interface profiles, set the IP addresses of the system’s Ethernet ports.
– Reset the system for these changes to take effect.
4 Load the earlier version of the boot loader. For example:
admin> load boot-sr network 10.10.10.10 stgsrb.bin
5 Load the earlier version of the tar file. For example:
admin> load tar network 10.10.10.10 stgrel.tar
6 Reset the system.
7 Restore a backup configuration made under the restored software version or one
of its predecessors.
Using a script to configure a Stinger unit
The TAOS command-line interface allows you to create configuration scripts with a
simple text editor and a Telnet client program with a Text Upload feature. This section
briefly describes how you can use a script to make changes to the Stinger
configuration.
Following are the basic steps:
1 Create a text file that contains the configuration commands as you normally
enter them in the TAOS command-line interface.
2 Log into the Stinger unit with sufficient permissions to change the configuration.
3 To upload the file to the Stinger unit, use the upload file feature of your Telnet
terminal software.
Following is an example of a text file that configures an SDSL line in shelf 1, slot 7:
new SDSL
set name = SF
set physical-address shelf = {shelf-1 slot-7 1 }
set enabled = yes
set line-config = { 0 1 static { any-shelf any-slot 0 } singlebaud 784000 coe
}
write -f
;
Note The write -f command causes the script to overwrite an existing
configuration without prompting.
