The ports on the CX116 are in GE full-duplex mode. The current version does not support
port rate auto-negotiation or duplex mode auto-negotiation between the local and peer ends.
Check that the speed and duplex modes on the local CX116 and peer end are the same before
any connection.
The logical numbers of the 32 ports are 0 to 31, which are used for running commands
remotely. A physical number is in slot number-port number format. Physical numbers are
used for locating ports when you connect network cables and view the mapping between the
ports on the pass through module and the server slots. The 16 front half-width slots of the
E9000 server are numbered 1 to 16. Each slot has two ports: slot number-1 and slot
number-2. For example, half-width slot 7 has ports 7-1 and 7-2, and half-width slot 15 has
ports 15-1 and 15-2.
Each full-width slot has four ports, which map to two half-width slots. For example, full-
width slot 7 maps to half-width slots 7 and 15, and full-width slot 7 has ports 7-1, 7-2, 15-1,
and 15-2.
