Dynamic configuration loading
6
NOTE
If you copy and paste a configuration into a management session, the CLI ignores the “!”
instead of changing the CLI to the global CONFIG level. You may get unexpected results if you
copy and paste a configuration instead of loading the configuration using TFTP.
•
Make sure you enter each command at the correct CLI level. Since some commands have
identical forms at both the global CONFIG level and individual configuration levels, if the CLI
response to the configuration file results in the CLI entering a configuration level you did not
intend, you can get unexpected results.
For example, if a trunk group is active on the device, and the configuration file contains a
command to disable STP on one of the secondary ports in the trunk group, the CLI rejects the
commands to enter the interface configuration level for the port and moves on to the next
command in the file you are loading. If the next command is a spanning-tree command with
syntax valid at the global CONFIG level as well as the interface configuration level, the software
applies the command globally. For example:
If the configuration file contains these commands.
interface ethernet
4/2
no spanning-tree
the CLI responds:
PowerConnect
(config)# interface ethernet 4/2
Error - cannot configure secondary ports of a trunk
PowerConnect
(config)# no spanning-tree
PowerConnect
(config)#
•
If the file contains commands that must be entered in a specific order, the commands must
appear in the file in the required order. For example, if you want to use the file to replace an IP
address on an interface, you must first remove the old address using no in front of the ip
address command, then add the new address. Otherwise, the CLI displays an error message
and does not implement the command. For example:
The configuration file contains these commands.
interface ethernet 3/1
ip address 10.10.10.1/24
The running-config file already has a command to add an address to 3/1, so the CLI responds
like this.
PowerConnect
(config)# interface ethernet 3/1
PowerConnect
(config-if-e1000-3/1)# ip add 10.10.10.69/24
Error: can only assign one primary ip address per subnet
PowerConnect
(config-if-e1000-3/1)#
To successfully replace the address, enter commands into the file as follows.
interface ethernet
3/1
no ip address 10.10.10.1/24
ip address 10.10.10.69/24
This time, the CLI accepts the command, and no error message is displayed.
PowerConnect
(config)# interface ethernet 3/1
PowerConnect
(config-if-e1000-3/1)# no ip add 10.10.10.1/24
PowerConnect
(config-if-e1000-3/1)# ip add 10.10.10.69/24
PowerConnect
-if-e1000-3/1)
