SFP ports cannot be used (see the table given in Port Combinations Usage Guidelines section).
• Each SFP port can be configured for SONET or Ethernet.
• SFP ports configuration parameter, (see the table given in Port Combinations Usage Guidelines section):
• Maximum of 4 x OC-48 interfaces are supported per interface module
• For each OC-48 port enabled, neighboring SFP ports cannot be configured
• OC-3 and OC-12 port configuration is supported on all ports simultaneously
