What It Means

The command output displays the alarm date, time, severity level, and description. An SSB failure or removal generates an fxp0 link alarm. The fxp0 link is the dedicated 100-Mbps Fast Ethernet link between the SSB and the Routing Engine. This link transfers routing table data from the Routing Engine to the forwarding table in the Internet Processor ASIC. The link also transfers, from the SSB to the Routing Engine, routing link-state updates and other packets destined for the router that have been received through the router interfaces.
