Solution Traffic statistics fields for logical interfaces in show interfaces commands show only

control traffic; the traffic statistics do not include data traffic. You can view the statistics

for all traffic only per physical interface.

IPv6 Interface Traffic Statistics Are Not Supported

Problem Description: The IPv6 transit statistics in the show interfaces command display all 0

values.

Solution EX Series switches do not support the collection and reporting of IPv6 transit statistics.

SNMP Counters ifHCInBroadcastPkts and ifInBroadcastPkts Are Always 0

Problem Description: The values for the SNMP counters ifHCInBroadcastPkts and

ifInBroadcastPkts are always 0.

Solution The SNMP counters ifHCInBroadcastPkts and ifInBroadcastPkts are not supported for

aggregated Ethernet interfaces on EX Series switches.

Interface Configuration or Connectivity Is Not Working

Problem Description: You encounter errors when you attempt to configure an interface on the

switch, or the interface is exhibiting connectivity problems.

Solution Use the port troubleshooter feature in the J-Web interface to identify and rectify port

configuration and connectivity related problems.

To use the J-Web interface port troubleshooter:

1. Select the option Troubleshoot from the main menu.

2. Click Troubleshoot Port. The Port Troubleshooting wizard is displayed. Click Next.

3. Select the ports to troubleshoot.

4. Select the test cases to be executed on the selected port. Click Next.
