4500G tracert timeout

[acampbell]

A few months ago I posted a question regarding a 4500G that does not respond during a traceroute.  Since I can't find my original post, I'm reposting.

Traceroute shows astericks and 'request timed out' for the 4500G.  The 4500G has three VLANs.  Traceroutes from hosts on each VLAN to hosts on another VLAN show this behavior.

  1    <1 ms    <1 ms    <1 ms  200.0.1.231


  2     *        *        *     Request timed out.


  3     4 ms     2 ms     2 ms  10.1.0.10

One reply to the original post mentioned adding the command 'ip unreachables enable'.  No change in behavior.

Does anyone else have a suggestion?
