Verifying The Pid Mode - Brocade Communications Systems DCX 8510-8 Hardware Installation Manual

Verifying the PID mode

2. Enter the tsClockServer command:
switch:admin> tsclockserver
"<ntp1;ntp2>"
In this syntax, 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 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

Verifying the PID mode

Before connecting the device to the fabric, verify that the WWN-based persistent port identifier (PID) feature on the device 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...
Fabric parameters (yes, y, no, n): [no] y
Domain: (1..239) [1]
Enable a 256 Area Limit
(0 = No,
1 = Zero Based Area Assignment,
2 = Port Based Area Assignment): (0..2) [0] 1
WWN Based persistent PID (yes, y, no, n): [no] yes
<command output truncated>
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.
