7. The final step on the 3012 is to save this config to NVRAM.
From the main page of the Element Manager, click Maintenance → Save Config to save
the configuration to NVRAM.
8. After saving the configuration of the 3012 to NVRAM, you need to configure the 4948. In
this example, we connect the Ethernet gateway module to the 4948 on ports gi1/16 and
17, with the gateway module 4/1 going to gi0/16 and gateway module 8/2 going to gi0/17.
Note that for reference purposes, we show removing the port channel added in the last
example and then setting up all other elements needed to support his redundancy. All of
these steps might or might not be necessary in your environment. Contact your network
engineer if you are not sure what you need to do for this to work.
After logging into the 4948 with sufficient privileges, execute the commands in
Example 7-15 on the 4948. Items that start with an exclamation mark (!) are for
reference/comments only and will not be executed.

Note: As mentioned previously, all changes done through the GUI take effect
immediately and are placed in the running config, but the changes in the running config
are not explicitly saved to NVRAM until you perform this step.
