NOTE
You can enter text following " ! " as a comment. However, the " !" is not a comment marker. It returns
the CLI to the global configuration level.
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. As a result, you might get different 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, then 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 whose syntax is valid at the global CONFIG
level as well as the interface configuration level, then the software applies the command globally. Here
is an example.
The configuration file contains these commands.
interface ethernet
2
no spanning-tree
The CLI responds like this.
device(config)#interface ethernet 2
Error - cannot configure secondary ports of a trunk
device(config)#no spanning-tree
device(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. Here is an example.
The configuration file contains these commands.
interface ethernet 11
ip address 10.10.10.69/24
The running-config already has a command to add an address to port 11, so the CLI responds like
this.
device(config)#interface ethernet 11
device(config-if-e1000-11)#ip add 10.10.10.69/24
Error: can only assign one primary ip address per subnet
device(config-if-e1000-11)#
To successfully replace the address, enter commands into the file as follows.
interface ethernet
11
no ip address 10.20.20.69/24
ip address 10.10.10.69/24
