3 Troubleshooting Functional Failures During Operation
73
No. Items to check and commands Action
2 Check if more than two devices
configuring the SML are connected,
and if the same SML ID is set for the
devices configuring the SML. If more than two devices configuring the SML are connected:
Perform the following procedure for recovery:
1.
Connect no more than two devices configuring the SML.
2. Remove from the peer link port the cable connecting the
excess SML devices to the devices configuring the SML.
3. Use the activate operation command to activate all ports
specified for a peer link on the devices configuring the SML.
4. Wait until
Full
is indicated for
SML Status
.
If the same SML ID is set for the devices configuring the SML:
The same SML ID is set for both SML devices. Perform the
following procedure for recovery:
1.
Set a new SML ID for either of the SML devices and then
restart the Switch.
2. For the other SML device, use the
activate
operation
command to activate all ports specified for a peer link.
3. Wait until
Full
is indicated for
SML Status
.
3 Check the cables connecting the
peer link ports of the SML devices. If a line failure has occurred on the peer link ports:
Perform the following procedure for recovery:
1. See 3.4.3 Actions to be taken for 100BASE-FX
[24S4X]/1000BASE-X problems , 3.4.4 Actions to be taken
for 10GBASE-R problems [10G models] , and 3.4.5 Actions
to be taken for direct attach cable problems [10G models] .
2. Put the peer link into the link-down status by, for example,
removing and then reconnecting the cables connected to all
peer link ports or by executing the
inactivate/activate
operation command.
3. After the peer link ports enter the link-up status, wait until
Full
is indicated for
SML Status
.
If the peer link ports are deactivated:
See 3.4.1 Ethernet port cannot be connected .
When
Full
is not indicated for
SML Status
:

Make sure that the cables are connected from the peer link
ports to the partner SML device.

Make sure that the SML functionality is enabled on the
partner SML device.
4 Use the
ping
operation command
to check the connectivity of the
Switch.
If the connectivity is lost, go to No. 5.
5
Use the show sml
channel-group
operation
command to check the
SML ChGr
status.

When the channel-group status of the Switch is Down
and the
channel-group status
of the neighboring device
is
Up
:
When the channel group of the Switch is down, the VLAN for
IP communication might also be down
Check the status of the Ethernet port belonging to the
channel group, and bring the channel group up.
