Command introduced before JUNOS Release 7.4.
Display status information about serial interfaces, including RS-232, RS-422/449, EIA-530, X.21, and V.35.
interface-type — On M-series and T-series routing platforms, the interface type is se-fpc/pic/port. On the J-series routing platform, the interface type is se-pim/0/port.
brief | detail | extensive | terse — (Optional) Display the specified level of output.
descriptions — (Optional) Display interface description strings.
media — (Optional) Display media-specific information about network interfaces.
snmp-index snmp-index — (Optional) Display information for the specified SNMP index of the interface.
statistics — (Optional) Display static interface statistics.
