Introduction 33
Managing the switch
2
In this syntax, ntp1 is the IP address or DNS name of the first NTP server, which the switch
must be able to access. Ntp2 is the name of the second NTP server and is optional. The entire
operand “< ntp1;ntp2 >” is optional; by default, this value is LOCL, which uses the local clock of
the principal or primary switch as the clock server.
switch:admin> tsclockserver
LOCL
switch:admin> tsclockserver "132.163.135.131"
switch:admin> tsclockserver
132.163.135.131
The following example shows how to set up more than one NTP server using a DNS name:
switch:admin> tsclockserver "10.32.170.1;10.32.170.2;ntp.localdomain.net"
Updating Clock Server configuration...done.
Updated with the NTP servers
Changes to the clock server value on the principal or primary FCS switch are propagated to all
switches in the fabric.
Managing the switch
SNMP v3 authentication
Two user roles are supported:
•
snmpadmin—Provides read-write access
•
snmpuser—Provides read-only access
Table 10 lists user login information. Each entry requires a separate password. The default
algorithm (MD5/SHA) is used to create the authentication keys.
1. AES = 128-bit encryption
For more information, refer to the snmpConfig commands supporting SNMPv3 configuration
parameters, as described in the
Fabric OS Command Reference Manual .
