Hi Sir,

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


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:

Cat6509#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Cat6509(config)#ip sl?


Please advise.

Thank you.

I'd like to use IP SLAs ICMP Echo Operation to track an object and attach it to a static route, as follows:


ip sla monitor 1

type echo protocol ipIcmpEcho

ip sla monitor schedule 1 life forever start-time now


track 1 rtr 1 reachability


ip route track 1


Since the command is not available on 12.2SXF, I guess the closest workaround is as follows:


rtr 1

type echo protocol ipIcmpEcho

rtr schedule 1 start-time now life forever


Cat6509(config)#track 1 ?

interface Select an interface to track

Unfortunately, I can't complete the configuration because the next command "track 1 rtr 1 reachability" is not available. Do you have further suggestion?

I just wonder why the output of Feature Navigator indicates that IP SLAs is supported in 12.2SXF but in actual fact is not. The tool seems to be wrong.

Thank you.

Ok..this is what I see under command looksup for "rtr responder". Looks like you need to upgrade to 12.2(31)SB2

If you want to run 7600 code on your 6500, you can upgrade to something in the 12.2(33)SRA train.

If you prefer to get an actual 6500 release that supports this, wait 1 month for 12.2(33)SXH to come out. It will support this feature.
