The above example indicates the following:
• There are six forwarding engines, 0 through 5.
• Since there are 48 ports on a Cisco MDS DS–X9448–768K9 module, each forwarding engine handles
eight ports.
• Each forwarding engine has 49136 entries in region 3 (the zoning region) for input. This is the main
region that is used, and consequently, has the largest amount of available entries.
• Forwarding engine 2 has only two entries that are currently in use out of the total 49136 in the zoning
region.
The commands that are used to view TCAM usage on fabric switches are different from the ones used for
director–class switches. For MDS 9148, MDS 9148S, and MDS 9250i fabric switches, use the show system
internal acltcam-soc tcam-usage command. For director class switches, MDS 9396S, and 32 Gbps fabric
switches, use the show system internal acl tcam-usage command.
