Chapter 5 Maintenance and Troubleshooting
Troubleshooting
No PTP flow between TP
2300/2700 Grandmaster
and client
(
If LED for port is OFF)
Cable connections Check the cable connections and SFP or
Ethernet connections.
Verify that SFP connector models are
recommended and supported.
Ethernet Auto Negotiation
settings
Check that either Ethernet Auto
Negotiation is enabled or that speed has
been set to a compatible level with the
connecting network element (
show
ethernet config
command).
Make sure that only full-duplex network
devices are used. The TP 2300/2700
does not support half-duplex devices,
such as hubs, for PTP connections.
No PTP flow between TP
2300/2700 Grandmaster
and client
(
If LED for port is ON
and ping to client is
unsuccessful)
VLAN / non-VLAN
configuration is incorrect
Verify that VLAN configuration is
correct with
show vlan-config eth2
Check VLAN and IP configuration of
PTP client
Note: The TP 2300/2700 uses the clock
ID as a unique identifier for PTP clients
and can only allow for one instance of the
clock id to be serviced. If a PTP client with
a single clock ID requests service using
two different IP addresses or VLANs, the
TP 2300/2700 will use the IP
address/VLAN of the latest request.
IP address configuration
is incorrect
Verify that IP configuration is correct
with
show ip config eth2
Verify that IP status is correct with
show ip status eth2
If status does not look correct, restart
interface with
set ip state eth2
ipv4 restart
IP address of ETH1 and
ETH2 ports are in the
same network/subnet
Make sure the IP addresses for MGMT,
ETH1 and ETH2 ports are on different
networks/subnets.
