The following sets of traps are supported:
• RFC 1157-dened traps — coldStart, warmStart, linkDown, linkUp, authenticationFailure, and egpNeighbborLoss.
• Dell Networking enterpriseSpecic environment traps — fan, supply, and temperature.
• Dell Networking enterpriseSpecic protocol traps — bgp, ecfm, stp, and xstp.
To congure the system to send SNMP notications, use the following commands.
