Installation and Basic Configuration Guide
If either of these events occur, the HP device shuts down the port and notifies all the upper layer protocols that the
port is down.
HP 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 occur:
• Link aggregation is enabled on the adjacent port (the paired port) and both ports have the same key
• LACP brings the port back up
• The port joins a trunk group
Displaying Link Aggregation and Port Status Information
Use the show link-aggregation 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:
HP9300(config-mif-1/1-1/8)# show link-aggregation ethernet 1/1
System ID: 00e0.52a9.bb00
Port [Sys P] [Port P] [ Key ] [Act][Tio][Agg][Syn][Col][Dis][Def][Exp] [Ope]
1/1 0
The command in this example shows the link aggregation information for port 1/1.
NOTE: The Ope column displays in software releases 07.6.04 and later.
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:
HP9300(config)# show link-aggregation
System ID: 00e0.52a9.bb00
Port [Sys P] [Port P] [ Key ] [Act][Tio][Agg][Syn][Col][Dis][Def][Exp][Ope]
1/1 1
1/2 1
1/3 1
1/4 1
1/5 1
1/6 1
1/7 1
1/8 1
NOTE: The Ope column displays in software releases 07.6.04 and later.
Syntax: show link-aggregation [ethernet <portnum>]
Use ethernet <portnum> to display link-aggregation information for a specific port.
NOTE: Ports that are configured as part of an aggregate link must also have the same key. For more
information about assigning keys, see the section titled "Configuring Link Aggregation Parameters" in the
Installation and Basic Configuration Guide .
