Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
A separate cache is managed for each node that sends a traceroute request. All replies to a single traceroute
request are cached at once. The hold-time begins when the last reply to a request is received. When the
hold-time limit is reached, all replies to that request are cleared. The size of each traceroute reply is limited
by the MTU of the interface.
When the maximum number of entries (size entries) is exceeded, all replies for the oldest request are deleted.
