Table 22 Information fields for the show ports info atm ports command
Field Description
PORT NUM Port number.
MDA DESCRIPTION This field describes the MDA:
• Quad OC-3c SM — dual port OC-3c single-mode fiber
• Quad OC-3c MM — dual port OC-3c multimode fiber
• OC-12c SM — single port OC-12c single-mode fiber
• OC-12c MM — single port OC-12c multimode fiber
SCRAMBLE ENABLE Parameter that enables/disables the scrambling option.
FRAMING MODE Indicates the framing for the port, either:
• sonet, which means the Synchronous Optical Network
format, the standard format in North America.
• sdh, which means the Synchronous Digital Hierarchy
clock format, the standard format in Europe.
MAX-BITS VPI For OC-3c, 11 bits split between NumVpiBits and
NumVciBits. NumVpiBits cannot exceed 6 bits for OC-3c.
For OC-12c, 13 bits split between NumVpiBits and
NumVciBits. NumVpiBits cannot exceed 8 bits for OC-12c.
MAX-BITS VCI This field is read only. It takes remaining bits from
NumVpiBits. For example, if NumVpiBits is 3 for OC-3c,
then NumVciBits is 8.
CLOCK SOURCE Indicates whether the Clock Source is either:
• line
• internal
LOOPBACK MODE Indicates the loopback mode:
• off
• internal
• external
ADMIN STATE Indicates the Admin State of the port, either:
• up
• down
STATUS Indicates the status of the port, either:
• up
• down
