# TRACERT

## Qualifiers:

RTC <ip address> /HOPS n /WAIT n

IPSET <ip address> to <ip address> /HOPS n /WAIT n

## Purpose:

Traces the path from the RTC
1. Real Time Clock. 2. Real Time Complex. The RTC is a card that is used for the IP phones signaling, and for the ESM, DHCP, FTP and TFTP servers, among others. Call progress, device status and screen updated messages are sent between the IP Phones and the RTC. or IP sets to a destination IP address (IPv4 or IPv6). The system response identifies the IP address of routers (or hops) traversed and the time it took to make three round trips to each device (including the destination) and back. TRACERT is useful for determining where performance bottlenecks might be occurring.

TRACERT supports the following sets only:

- 5312 IP

- 5320/5320e IP

- 5324 IP

- 5330/5330e IP

- 5330/5330e IP

- 5360 IP

- 69xx IP

NOTES

- The IPSET trace results are influenced by the DiffServ or Differentiated Services Code Point (DSCP) value assigned to packets. To ensure that trace packets received the same priority as voice packets, the DiffServ value should be set to the default 46. The value is programmed through DHCP Option 134 in DHCP Options (see DHCP programming).

- Tracing routes to or from Teleworker devices could be impossible as the trace route packets may not "know" how to get to the device and back unless the routing tables are set up along the entire path. The inability to resolve IP addresses due to issues with Network Address Translation (NAT)
  For a computer to communicate with other computers and Web servers on the Internet, it must have an IP address. An IP address is a unique 32-bit number that identifies the location of your computer on a network. An IP address is similar to a street address in that it is means to find out exactly where you are and deliver information to you. Network Address Translation allows a single device, such as a router, to act as an agent between the Internet (or "public network") and a local (or "private") network. This means that only a single, unique IP address is required to represent an entire group of computers. and the presence of firewalls that block trace route packets also pose problems with respect to Teleworker.

## Details:

The </HOPS n> option:

Specifies the maximum number of hops in the path to search for the target destination. The maximum is 30. The default (specified by omitting the option) is 30.

The </WAIT n> option:

RTC Command: Specifies the amount of time in seconds to wait for replies from each hop and destination. The maximum is 60 seconds and the minimum is 1 second. The default (specified by omitting the qualifier) is 5 seconds. If a reply is not received within the time specified, an asterisk (*) is displayed in the response.

IPSET Command: Specifies the amount of time in milliseconds to wait for replies from each hop and destination. The maximum is 999 milliseconds. The default (specified by omitting the qualifier) is 250 milliseconds. If a reply is not received within the time specified, an asterisk is displayed in the response.

The HOPS and WAIT options can be entered alone, together, or omitted.

A "Request timed out" error indicates that the trace timed out waiting for the destination to reply. Likely causes of the time-out include

- the trace was interrupted by higher priority call control traffic

- the target IP set was unplugged from the LAN or power

- the target IP set was failing over or back

- a network issue causing lost connectivity between the IP set and the controller

An "Unknown IP Set" response indicates that the specified IP address is not associated with a registered IP Set on this MiVoice Business system.

NOTE: The spaces in the command are important. There must be at least one space between the qualifiers and no space directly after a /.
