Dynamic configuration loading
7
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 4/2
no spanning-tree
The CLI responds like this:
BigIron RX(config)# interface ethernet 4/2
Error - cannot configure secondary ports of a trunk
BigIron RX(config)# no spanning-tree
BigIron RX(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 3/1
ip address 10.10.10.1/24
The running-config already has a command to add an address to 3/1, so the CLI responds like
this:
BigIron RX(config)# interface ethernet 3/1
BigIron RX(config-if-e1000-3/1)# ip add 10.10.10.69/24
Error: can only assign one primary ip address per subnet
BigIron RX(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:
BigIron RX(config)# interface ethernet 3/1
BigIron RX(config-if-e1000-3/1)# no ip add 10.10.10.1/24
BigIron RX(config-if-e1000-3/1)# ip add 10.10.10.69/24
BigIron RX-if-e1000-3/1)
•
Always use the end command at the end of the file. The end command must appear on the last
line of the file, by itself.
Loading the configuration information into the running-config
You can load the configuration information from a TFTP server. To load the file from a TFTP server,
use either of the following commands:
•
copy tftp running-config <ip-addr> <filename> [overwrite]
•
ncopy tftp <ip-addr> <filename> running-config
