I have a Catalyst 6509-E with Supervisor Engine 32. Its IOS software is as follows:
Major Rel : 12.2SXF
Rel : 12.2(18)SXF6
Platform : CAT6000-SUP32/MSFC2A
Feat. Set : ENTERPRISE SERVICES SSH
Image filename : s3223-entservicesk9_wan-mz.122-18.SXF6.bin
From Feature Navigator, the feature "IP SLAs - ICMP Echo Operation" is supported. But in actual fact, the command is not available, as follows:
Enter configuration commands, one per line. End with CNTL/Z.
