29. th an SNMP Agent The WDM4 with a SNMP Agent board installed is a plug and play device Once connected to the network and powered ON the WDM64 starts operating according to factory set default values However to ensure proper operation and maximum performance specific to your network configuration and to provide SNMP access some environment specific parameters must be configured through the Administrative Interface The following steps should be taken Global Setup Connect a terminal to the Administrative Interface Port Log in to the Administrative Interface see Chapter 2 3 Initialize all the WDM4 parameters to their default values Use the following command sequence init nvram warm reset 4 Wait until you see the LOGIN prompt again Log in to the Administrative Interface Now all system parameters have been initialized to their default values IP Setup SNMP Setup Modify the system IP configuration to match your IP network Use the set ip conf command in order to provide an IP address a netmask and a broadcast address For example set ip cfg 129 1 1 64 255 255 255 0 129 1 1 255 Check that the actual IP configuration matches the desired one SYS_console gt get ip cfg The device IP address netmask and broadcast are IP address 129 001 001 064 IP netmask 255 255 255 000 IP broadcast 129 001 001 255 Set the default gateway address using the set gatew command for more details see Chapter 3 IP Commands
