  47. Basic Performance check

  48. show Commands The switch supports two slots for the supervisor engines. A CLI command is provided to allow the administrator to inspect which of the SFMs is active: 6500# show fabric active Active fabric card in slot 5 No backup fabric card in the system The mode of operation in use by the SFM can also be inspected by issuing the following command: 6500# show fabric switching-mode Fabric module is not required for system to operate Modules are allowed to operate in bus mode Truncated mode is not allowed unless threshold is met Threshold for truncated mode operation is 2 SFM-capable cards Module Slot Switching Mode 1 Crossbar 2 Crossbar 3 Crossbar 5 DCEF

  49. show Commands (Cont.) The status of the SFM can be inspected by using the following command: 6500# show fabric status slot channel speed module fabric status status 1 0 8G OK OK 2 0 8G OK OK 3 0 8G OK OK 5 0 20G OK OK The utilization of the SFM can be inspected by using the following command: 6500# show fabric utilization slot channel speed Ingress % Egress % 1 0 8G 28 0 2 0 8G 0 0 3 0 8G 0 25 5 0 20G 0 0
