Troubleshooting Agent Greeting
Network Interfaces
Agent Greeting generates network traffic for the following reasons:
• Multicast traffic from server card for auto-discovery of clients (one
packet every 15 seconds during discovery sequence, one packet per
minute during normal operation.
• FTP traffic for transfer of greetings during normal operation.
• HTTP traffic for Browser User Interface interactions.
• Telnet for maintenance access.
Loss of network connectivity
If the network becomes disconnected from the Agent
Greeting Card, the serial maintenance port will display
the following each time it attempts to transmit a packet:
-> lnIsa0: no carrier
lnIsa is the device driver for the network interface. No
Carrier indicates a cable or hub fault on the network.
Duplicate IP Addresses
If another device on the network is responding to the
same IP address as an Agent Greeting card, a warning
message will be displayed on the Agent Greeting
Maintenance terminal giving the Ethernet MAC address
of the duplicate node.
