• For ports directly attached to the chassis you can have a maximum of 4 sessions per port pipe. Refer to Port Numbering Convention for the exact port location on switch line cards. Setting the Speed and Duplex Mode of Ethernet Interfaces To discover whether the remote and local interface requires manual speed synchronization, and to manually synchronize them if necessary, use the following command sequence. 1 Determine the local interface status. Refer to the following example. EXEC Privilege mode show interfaces [interface | stack-unit stack-unit-number] status 2 Determine the remote interface status. EXEC mode or EXEC Privilege mode [Use the command on the remote system that is equivalent to the first command.] 3 Access CONFIGURATION mode. EXEC Privilege mode config 4 Access the port. CONFIGURATION mode interface interface-type 5 Set the local port speed. INTERFACE mode speed {10 | 100 | 1000 | 10000 | auto} NOTE: If you use an active optical cable (AOC), you can convert the QSFP+ port to a 10 Gigabit SFP + port or 1 Gigabit SFP port. You can use the speed command to enable the required speed. 6 Optionally, set full- or half-duplex. INTERFACE mode duplex {half | full} 7 Disable auto-negotiation on the port. INTERFACE mode no negotiation auto If the speed was set to 1000, do not disable auto-negotiation. 8 Verify configuration changes. INTERFACE mode show config Interfaces 504
