Troubleshooting Steps and

Action

 

 

Command

 

 

 

 

 

 

1

Use the show logging command to

Check the log information for physical failures.

 

 

check if any failure occurs.

 

 

2

Check if filtering and QoS are set

Certain packets may have been discarded by filtering, or packets may have been

 

correctly.

discarded through bandwidth monitoring, discarding control, or shaper of the QoS

 

 

control. Check to see if the conditions of filtering and QoS control in the configuration

 

 

have been set up correctly and if bandwidth monitoring, discarding control, or shaper

 

 

has been set up appropriately for system operation.

 

 

 

For the procedure, see "3.23.1 Checking Filtering/QoS Setting Information."

 

 

 

 

3

Check the settings of IPv6 multicasts if

Check the following:

 

 

you want to use IPv6 multicast at the

• Check to see that the settings by configuration command are applied to the system

 

same time.

[IP8800/S3600]

 

 

[IP8800/S3600] [IP8800/S6700]

 

 

 

[IP8800/S6600] [IP8800/S6300]

When the settings by configuration command swrt_multicast_table are

 

 

applied, "On" is indicated on "Current selected swrt_multicast_table:" by entering

 

 

the show system command.

 

 

 

Current selected swrt_multicast_table: On

 

 

When "Off" is indicated after the

configuration command

 

 

swrt_multicast_table has been executed, restart the system.

 

 

• When IPv6 multicast and MLD snooping are used at the same time, configure IPv4

 

 

multicast in the VLAN. [IP8800/S3600]

 

 

 

When IPv6 multicast is used in the VLAN, "On" is displayed in "IPv4 Multicast

 

 

routing:" by entering the igmp-snoopingcommand.

 

 

 

IPv6 Multicast routing: On

 

 

 

• When static group entry function of IPv6 multicast is used in the VLAN, set

 

 

multicast router port to the ports that are necessary for multicast communication.

 

 

• When the number of entries registered in MLD snooping exceeds the

 

 

accommodation conditions, the excess multicast relay entries of IPv6 multicast can

 

 

communicate only between multicast router ports. Therefore, set up network

 

 

configuration so as not to exceed the registered entries of MLD snooping.

 

 

When the registered entries of MLD snooping exceeds the accommodation

 

 

conditions, log information is displayed in the following:

 

 

MLD snooping: The number of the MLD snooping entry

 

 

exceeded the capacity of this system.
