Port Trunking
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.
HPswitch(config)# aaa port-access authenticator e b1
LACP has been disabled on 802.1x port(s).
HPswitch(config)#
The switch will not allow you to configure LACP on a port on which port
access (802.1x) is enabled. For example:
HPswitch(config)# int e b1 lacp passive
Error configuring port < port-number >: LACP and 802.1x
cannot be run together.
HPswitch(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:
HPswitch(config)# port-security e a17 learn-mode static
address-limit 2
LACP has been disabled on secured port(s).
HPswitch(config)#
The switch will not allow you to configure LACP on a port on which port
security is enabled. For example:
HPswitch(config)# int e a17 lacp passive
Error configuring port A17: LACP and port security cannot
be run together.
HPswitch(config)#
To restore LACP to the port, you must remove port security and re-enable
LACP active or passive.
