destination. Each router along the path is required to decrement the TTL on a packet by at least 1
before forwarding it, so the TTL is effectively a hop count. When the TTL on a packet reaches 0,
the router is supposed to send back an ICMP Time Exceeded message to the source system.
Tracert determines the route by sending the first echo packet with a TTL of 1 and incrementing
the TTL by 1 on each subsequent transmission until the target responds or the maximum TTL is
reached.. The route is determined by examining the ICMP Time Exceeded messages sent back
by intermediate routers.
The IP address can use a domain-style address, providing the dns and/or hosts configuration
has been properly entered.
6.8.8 VERIFY CONFIGURATION SETTINGS - VFY
The vfy command is used to report configuration settings for the following categories using the
indicated syntax:
• vfy app - application installation and run-time status
• vfy banner
• vfy cfg … - application instance selection
• vfy console – cug list for the console
• vfy cug - closed user group definitions
• vfy dns - domain name server configuration
• vfy dtproduct
• vfy hosts - host-IP translation table
• vfy mod - module configuration and status
• vfy snmp - snmp settings
• vfy stby – for duplex configurations only (see sections 6.9.3 and 6.9.4.)
The verify reports for banner, cug, dtproduct, dns, hosts, and snmp are simple representations
of the configuration parameters described in each corresponding command. The more complex
verify reports are explained in this section.

The vfy app (or vfyapp) command shows the list of installed applications, along with their build
(revision) numbers and build dates. Unregistered applications are displayed with the notation
"not registered." The display continues with a list of applications currently running in each
application slot (instance), including "none", along with an internal identifier. Instances that are
removed from services will show an "oos" status. Instances configured for an unregistered
application will show an "unreg" status. For some applications, there may occasionally appear a
short temporary status report generated by some instances of the application.
