Troubleshooting an Aggregated Ethernet Interface
Troubleshooting issues for aggregated Ethernet interfaces:
Show Interfaces Command Shows the LAG is Down
Problem
The show interfaces terse command shows that the LAG is down.
Solution
Check the following:
- Verify that there is no configuration mismatch.
- Verify that all member ports are up.
- Verify that a LAG is part of family ethernet—switching (Layer 2 LAG) or family inet (Layer 3 LAG).
- Verify that the LAG member is connected to the correct LAG at the other end.
- Verify that the LAG members belong to the same switch (or the same Virtual Chassis).
Logical Interface Statistics Do Not Reflect All Traffic
Problem
The traffic statistics for a logical interface do not include all of the traffic.
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
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.
