interface serial

Last Updated : May 31, 2019 |

Enters Serial interface or sub interface configuration mode. If the specified interface or sub interface does not exist, the system creates it and enters its configuration mode. Use no interface serial to delete the interface. The no interface serial command can be used only to delete sub L3 and sub frame relay interfaces. The command fails for USP interfaces and when higher or lower layers are defined for that interface.

For USP interfaces if_number has the syntax:
