The vlan parameter specifies the VLAN or VLANs for which ports are enabled.
Specified ports must be a member of the VLAN. If no value or all is specified,
the specified ports are enabled for all VLANs to which they belong.
Note that when a disabled VLAN is re-enabled on a port, the port
automatically has ingress filtering disabled, as long as there are no other
VLANs disabled on the port, and as long as ingress filtering was not previously
enabled by using the set switch port command.
Example To enable the default vlan on port 1, use the command:
ena swi po=1 vlan=1
set lacp
Syntax SET LACP PRIOrity=priority
[THRASHAction={LEarndisable|LINkdown|NONE|POrtdisable|V
LANdisable}] [THRASHTimeout={None|1..86400}]
Description This command modifies the LACP parameters.
The thrashaction parameter specifies the action the router or switch takes
when it detects MAC address thrashing on any trunk created by LACP.
Thrashing occurs when one or more ports or trunks repeatedly learn the same
MAC addresses, for example, as a result of a network loop. The router or
switch applies the trunk’s thrashaction to all ports in the trunk.
Take care with the thrashaction parameter because misuse can impair your
network operation.
Set the thrashaction parameter to:
■ none to apply no thrash limiting on the trunk.
■ learndisable to disable MAC address learning on all ports in the thrashing
trunk, until the period specified with the thrashtimeout parameter has
elapsed. The default is learndisable.
■ portdisable or linkdown to disable all ports in the thrashing trunk until
either the period specified by the thrashtimeout parameter has elapsed, or
until the ports or subset of ports in the trunk are re-enabled by the enable
switch port
command. If you specify linkdown, the link state is down; if
you specify portdisable, the link state remains up.
■ vlandisable to block all traffic on the VLAN where the address was
learned, on all ports in the thrashing trunk, until either the period specified
by thrashtimeout has elapsed, or until the ports are re-enabled using the
enable switch port vlan
command. When thrashaction=vlandisable, there
is only one timer per trunk, so if multiple VLANs have been disabled on a
trunk, the timer starts when the last VLAN was disabled. When the timer
expires, all VLANs are re-enabled on the trunk. When
thrashaction=vlandisable
, ingress filtering is automatically enabled on all
ports in the trunk.
The thrashtimeout parameter specifies the time, in seconds, for which the
switch employs the thrash action specified by the thrashaction parameter. The
thrashtimeout
cannot be set to none if thrashaction=learndisable. If
thrashtimeout=none, and thrashaction is then changed to learndisable, then
the router or switch automatically changes the thrashtimeout to 1 second.
