Sun Microsystems CP3240 manual 12.4 1G Configuration for RTM Optical Port

4.12.41G Configuration for RTM Optical Port

For 1G operation, an SFP module must be used and the port (17-20) must be set to auto-negotiate. When you enable auto-negotiation, 1G operation is automatically enabled and 10G operation is automatically disabled.

For all 10G RTM optical ports no auto-negotiateis the default setting. Therefore, 1G operation must be explicitly enabled. Note that Base 10G port, 0/25 and 0/27 do not support 1G operation. The Fabric 10G RTM optical ports support both 1G and 10G operation.

where <0/xx> is the port number of the RTM on Fabric. Valid entries are 0/17, 0/18, 0/19, and 0/20.

For each port on the RTM, enter the command.
