Verifying The Pid Mode - Brocade Communications Systems DCX 8510-4 Hardware Reference Manual

Verifying the PID mode

Before connecting the Brocade DCX 8510-4 to the fabric, verify that the WWN Based persistent
port identifier (PID) feature on the Brocade DCX 8510-4 matches the other switches in the fabric.
This parameter must be identical for all switches in the fabric and is set using the configure
command as shown in the following example:
switch:admin>configure
Configure...
You can check the PID setting using the configshow command as in the following example. You can
use the | grep -i pid qualifier to pinpoint the PID information.
switch:admin> configshow | grep -i pid
fabric.ops.mode.pidFormat:1
fabric.wwnPidMode:1
The 1 indicates that the WWN Based persistent PID feature is enabled. The default value is 0 for
disabled.

where ntp1 is the IP address or DNS name of the first NTP server, which the switch must be
able to access. The variable ntp2 is the second NTP server and is optional. The 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.
The tsClockServer command accepts multiple server addresses in either IPv4, IPv6, or DNS
name formats. When multiple NTP server addresses are passed, tsClockServer sets the first
obtainable address as the active NTP server. The rest will be stored as backup servers that can
take over if the active NTP server fails. The principal or primary FCS switch synchronizes its
time with the NTP server every 64 seconds.
switch:admin> tsclockserver
LOCL
switch:admin> tsclockserver "132.163.135.131"
switch:admin> tsclockserver
132.163.135.131
switch:admin>
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
