Troubleshooting Network Connectivity Problems
If the RMON MultiProbe Module does not appear to be transmitting or
receving traffic properly on the network, it could indicate that there is no
connection to the network. Try performing one or more of the following
troubleshooting actions:
❑ From the 3Com management interface (for example, ONline
management module), verify that the RMON MultiProbe Module
interfaces are set to the appropriate networks.
❑ Using the RMON MultiProbe Module configuration menus, verify that
the following terminal parameters are set correctly:
– IP address
– Subnet mask
– Default gateway
For terminal configuration information, refer to Chapter 2, Installing
the Module, the section Connecting a Terminal.
❑ Use the ping utility to confirm there is network connectivity.
❑ Verify that the Ethernet configuration is valid. Refer to the
documentation that accompanied the Ethernet media modules for
more information.
If the RMON MultiProbe Module responds to pings, but not to SNMP, verify
that the RMON client software community string matches the RMON
MultiProbe Module community string default value. The RMON MultiProbe
Module default community name is admin. (Community names are
case-sensitive.) The admin community name provides read-write access.
Note: You can only modify the community name using the RMON
client software.
