All,
I have an issue that even though I have both the idle and absolute timeout
configured but when I try to open telnet session from the Switch, the first
session gets drop which is expected but when I try it second time I get the
following message.

*% List#108-MYACL already contains this IP address pair*

I tried it couple of time and manually clear the dynamic ACL using "clear
access-template 108 MYACL host 172.16.8.8 any"" but no luck so far.
I remember seeing similar issue with someone in the groupstudy posting but
in my case it is not working.
