Probable Cause
VLAN / non-VLAN
configuration is incorrect
or
IP address configuration
is incorrect
Client configuration for
acceptable Grandmaster
is incorrect
PTP state set to Disable
PTP Max Clients setting
for TP5000 exceeded
PTP domain setting for
GM does not match
client's domain
PTP Unicast - Dynamic
negotiation disabled on
GM , with Unicast
-Dynamic clients
PTP max allowable rate
settings for sync and
delay less than values of
client
Troubleshooting Procedure /
Corrective Action
Verify that IP configuration is correct with
"show ip config ioc1"
Verify that VLAN configuration is correct
with "show vlan-config ioc1"
Verify that IP status is correct with "show
ip status ioc"
If status does not look correct, restart
interface with "set ip ioc1-1 restart" or "set
ip ioc1-2 restart", as appropriate
Check acceptable Grandmaster setting of
client.
Change PTP state to Enable with "
state" command for the port.
If number of clients exceeds max setting
for TP5000, extra clients are ignored.
Change max clients setting with "
max-client" command
Verify domain setting for GM matches the
domain setting for the client. Check GM
domain setting with "show ptp-config
common" command for the port.
Check Unicast - Dynamic negotiation
setting of GM with "show ptp-config
common" command for the port. Use the
set ptp
" unicast dynamic negotiate
ioc1-[y] enable" command for the port.
Check sync-limit and delay-limit settings
of GM with "show ptp-config common"
command for the port. If max allowable
rates of GM are less than those of client,
set ptp
use the " sync-limit" and "
delay-limit" commands to increase rates
to meet or exceed rate values for clients.
Or decrease rate settings for client to a
value less than or equal to settings of GM.
