values it is very critical to ensure that each SPB enabled switch in the network uses a
unique ISIS System-Id value.
If you do decide to change the System ID, it is recommended to set the locally
administered bit. The second least significant bit of the most significant byte of the MAC
address should be set to 1 to indicate the MAC address as locally administered. For more
details, please go to http://en.wikipedia.org/wiki/MAC_address.
Please note that if you change the System ID after ISIS has already been enabled, you
must also change the nickname. If you do not wish to change the nickname, you will still
need to temporary change the nickname. After you change the System ID and temporarily
change the nickname, enable ISIS, disable ISIS, change the nickname back to the original
value, and then enable ISIS again.
