Port Trunking
Trunk Group Operation Using LACP
Status Name
Meaning
LACP Status
Success: LACP is enabled on the port, detects and synchronizes with a device on the other end of the
link, and can move traffic across the link.
Failure: LACP is enabled on a port and detects a device on the other end of the link, but is not able to
synchronize with this device, and therefore not able to send LACP packets across the link. This can be
caused, for example, by an intervening device on the link (such as a hub), a bad hardware connection,
or if the LACP operation on the opposite device does not comply with the IEEE 802.3ad standard.
LACP Notes and Restrictions
802.1X (Port-Based Access Control) Configured on a Port.
To main
tain security, LACP is not allowed on ports configured for 802.1X authenticator
operation. If you configure port security on a port on which LACP (active or
passive) is configured, the switch removes the LACP configuration, displays
a notice that LACP is disabled on the port(s), and enables 802.1X on that port.
ProCurve(config)# aaa port-access authenticator b1
LACP has been disabled on 802.1x port(s).
ProCurve(config)#
The switch will not allow you to configure LACP on a port on which port
access (802.1X) is enabled. For example:
ProCurve(config)# int b1 lacp passive
Error configuring port < port-number >: LACP and 802.1x
cannot be run together.
ProCurve(config)#
To restore LACP to the port, you must first remove the port’s 802.1X configu
ration and then re-enable LACP active or passive on the port.
Port Security Configured on a Port.
To maintain security, LACP is not
allowed on ports configured for port security. If you configure port security
on a port on which LACP (active or passive) is configured, the switch removes
the LACP configuration, displays a notice that LACP is disabled on the port(s),
and enables port security on that port. For example:
ProCurve(config)# port-security a17 learn-mode static
address-limit 2
LACP has been disabled on secured port(s).
ProCurve(config)#
