Using RACADM
Open a serial/Telnet/SSH text console to CMC, log in, and type:
racadm setled -m <module> [-l <ledState>]
where <module> specifies the module whose LED you want to configure.
Configuration options:
•
server-nx where n = 1-8 and x = a, b, c, or d
•
switch- n where n =1–6
• cmc-active
and <ledState> specifies whether the LED should blink.
Configuration options:
• 0 — not blinking (default)
•1 — blinking
Configuring SNMP Alerts
Simple network management protocol (SNMP) traps, or event traps, are
similar to e-mail event alerts. They are used by a management station to
receive unsolicited data from CMC.
You can configure CMC to generate event traps. Table 12-2 provides an
overview of the events that trigger SNMP and e-mail alerts. For information
on e-mail alerts, see "Configuring E-mail Alerts" on page 423.
NOTE: Starting with CMC version 2.10, SNMP is now IPv6 enabled. You can
include an IPv6 address or fully qualified domain name (FQDN) in the destination
for an event alert.
