Chapter 5 Managing the Passport 8672ATME Module with the CLI 87Using the Passport 8672ATME ModuleTable 22 describes the information fields for the show ports info atmall command.Table 22 Information fields for the show ports info atm all commandField DescriptionPORT NUM Port number.MDA DESCRIPTION This field describes the MDA:• Quad OC-3c SM — quad port OC-3c single-mode fiber• Quad OC-3c MM — quad port OC-3c multimode fiber• OC-12c SM — single port OC-12c single-mode fiber• OC-12c MM — single port OC-12c multimode fiberSCRAMBLE ENABLE Parameter that enables/disables the scrambling option.FRAMING MODE Indicates the framing for the port, either:• sonet (Synchronous Optical Network), the standardformat used in North America.• sdh (Synchronous Digital Hierarchy), the standardformat used worldwide except in North America.MAX-BITS VPI For OC-3c, 11 bits split between NumVpiBits andNumVciBits. NumVpiBits cannot exceed 6 bits for OC-3c.For OC-12c, 13 bits split between NumVpiBits (default is 4)and NumVciBits (default is 9). NumVpiBits cannot exceed 8bits for OC-12c.MAX-BITS VCI This field is read only. It takes remaining bits fromNumVpiBits. For example, if NumVpiBits is 3 for OC-3c,then NumVciBits is 8.CLOCK SOURCE Indicates whether the Clock Source is either:• line• internalLOOPBACK MODE Indicates the loopback mode::• off• internal• externalADMIN STATE Indicates the Admin State of the port, either:• up• downSTATUS Indicates the status of the port, either:• up• down
