What do I need to consider when copying a configuration file over to a new switch?
Posted on 2013-05-21
I am adding a switch to our network. I am going to connect a C3560-IPBASEK9-M to an existing C2960-LANBASE-M.
At first, I tried loading an existing configuration from a similar switch to the 3560. This is a fairly simple network and all switches are configured similiarly. Simply copying the config did not work.
After some reading, I learned that it would probably be best not to copy over the NTP commands, so I can enter them, allowing the new switch to set its own ‘ntp clock-period’.
I learned that aside from deleting any existing vlan.dat file, I should start the switch in ‘transparent mode’ and then enter the vtp domain and password and set it to client mode.
I read that I should not use ‘spanning tree’ or ‘portfast’ on the ports connecting the two switches. (Not that I was)
Although I believe both switches have auto-sensing and don’t need a cross-over cable, I think I will use one anyway.
I figured out on my own, that it would probably be best to create any banners manually. It seems the control character causes some issues if copied.
Is it okay to copy over the mls qos commands as is?
Are there any other considerations I should make when copying a config file from one switch to another?
