IP Line Description, Installation and Maintenance
The output for each Echo Server displays the following information:
• Configured – the IP address: port configured for this Echo Server in
LD 117
• Actual – the IP address: port used for this Echo Server, followed by an
explanation in parenthesis. This is different from the “Configured”
parameter only when the default address (0.0.0.0) has been configured.
The explanation in parenthesis is one of the following:
— (TLAN IP, this card) – the IP address used is the TLAN network
interface of this card; the Echo Server is active on this card.
— (node IP, this card) – the IP address used is the Node IP address; the
Echo Server is active on this card because it is the node master.
— (node IP, other card) – the IP address used is the Node IP address,
but another card is currently the Node master; the Echo Server is not
active on this card.
— (not this card) – the IP address is not this card’s TLAN IP address or
the Node’s IP address; the Echo Server is not active on this card.
• LTPS request sent – the number of Resolve Port Mapping Request
messages sent from the LTPS to IP Phones, with this Echo Server
identified as the one to contact.
• Failed resp rec.d – the number of Resolve Port Mapping Ack messages
received from the IP Phones that had the public IP address and port
configured as 0.0.0.0:0000. Each increment of this counter indicates an
IP Phone never received the Discover Port Mapping Ack response from
the Echo Server (all 10 attempts failed).
The two peg counts give an indication of the interaction this LTPS is having
with the Echo Server. It is not a direct sign of the health of the Echo Server;
network conditions for IP Phones registered to this LTPS may be preventing
communication with this Echo Server while another LTPS’s IP Phones have
no problem. The echoServerShow command output can help to understand
why a particular IP Phone registered to a LTPS may be having difficulties or
helps to uncover patterns of communication problems between IP Phones and
Echo Servers.
A sample output is shown in Figure 39 on page 180.
