Ethernet module features
Because you can change SFPs, inconsistencies can arise in the configuration file if you swap
SFPs of different speeds. The port operates correctly after you change the SFP, but the
configuration file can contain inappropriate Autonegotiation settings because of prior CLI
actions. The system ignores these inconsistencies and does not generate an error. You can
save the running configuration to update the file with correct Autonegotiation settings for the
port.
