Displaying and determining the status of aggregate links

Events that affect the status of ports in an aggregate link

Dell PowerConnect devices can block traffic on a port or shut down a port that is part of a trunk
group or aggregate link, when a port joins a trunk group and the port on the other end of the link
shuts down or stops transmitting LACP packets. Depending on the timeout value set on the port,
the link aggregation information expires. If this occurs, the Dell PowerConnect device shuts down
the port and notifies all the upper layer protocols that the port is down.
Dell PowerConnect devices can also block traffic on a port that is initially configured with link
aggregation. The port is blocked until it joins a trunk group. In this case, traffic is blocked, but the
port is still operational.
A port remains blocked until one of the following events occurs:

Displaying link aggregation and port status information

Use the show link-aggregate command to determine the operational status of ports associated
with aggregate links.
To display the link aggregation information for a specific port, enter a command such as the
following at any level of the CLI.
PowerConnect#show link-aggregate ethernet 1/1
System ID: 00e0.52a9.bb00
Port
1/1
The command in this example shows the link aggregation information for port 1/1.
To display the link aggregation information for all ports on which link aggregation is enabled, enter
the following command at any level of the CLI.
PowerConnect#show link-aggregate
System ID: 00e0.52a9.bb00
