3 Troubleshooting Functional Failures During Operation
72
No. Items to check and commands Action
7 Check whether the sending of flush
control frames is set on the Switch.

When not set:
Wait until aging of the MAC address table on the upstream
switch has finished.

When set:
Check the configuration of the port and the sending VLAN for
which sending of flush control frames has been set. If the
configuration is not correct, set the configuration again.
8 Check whether the sending of MAC
address update frames is set on the
Switch.

When not set:
Wait until aging of the MAC address table on the upstream
switch has finished.

When set:
- Check whether the VLAN that has learned the MAC
addresses on the port connected to the terminal is included
in the uplink port pair. If the VLAN is not included, specify the
setting again.
- Check whether the same VLAN is set for both ports of the
uplink port pair (primary and secondary). If different VLANs
are set, set the same VLAN.
For other cases, go to No. 9.
9 Use the operation command
show
switchport-backup
mac-address-table update
statistics
to make sure the
value displayed for
Transmission
over flows
has been
incremented.
If the value has been incremented, the number of applicable MAC
addresses for MAC address update frames exceeds 1024.

If the MAC addresses not applicable for MAC address
update frames can be deleted at the VLAN level:
Set the VLAN to be processed.

If the VLAN cannot be processed:
Wait until aging of the MAC address table on the upstream
switch has finished.

If a failure occurs when SML is used, isolate the cause of the problem according to the
failure analysis method described in the following table.
Table 3-29 Failure analysis method for SML
No. Items to check and commands Action
1 Use the
show sml
operation
command to check the SML status.
If
Conflict
is displayed for
SML Status
, go to No. 2.
If
Standalone
is displayed for
SML Status
, go to No. 3.
If
Full
is displayed for
SML Status
, go to No. 4.
If the SML domain is different from that set on the peer:
For
sml domain
, set the same domain ID as that set on the peer.
