If one IRF fabric uses another IRF fabric as the intermediate device for LACP MAD, ARP MAD, or ND
MAD, you must assign the two IRF fabrics different domain IDs for correct split detection. False
detection causes IRF split.
An IRF fabric has only one IRF domain ID. You can change the IRF domain ID by using the following
commands:
irf domain
,
mad enable
,
mad arp enable
, or
mad nd enable
. The IRF domain
IDs configured by using these commands overwrite each other.
Examples
# Set the IRF domain ID to 10.
<Sysname> system-view
[Sysname] irf domain 10
irf link-delay
Use
irf link-delay
to set a delay for the IRF ports to report a link status change event.
Use
undo irf link-delay
to restore the default.
Syntax
irf link-delay interval
undo irf link-delay
Default
The delay time is 4 seconds.
Views
System view
Predefined user roles
network-admin
Parameters
interval
: Sets the IRF link status change report delay, in the range of 0 to 10000 milliseconds. If
the interval is set to 0, link status change events are reported without any delay.
Usage guidelines
The device delays reporting link status change events of an IRF port, but it does not delay reporting
link status change events of an IRF physical interface.
Examples
# Set the IRF link status change report delay to 300 milliseconds.
<Sysname> system-view
[Sysname] irf link-delay 300
irf mac-address persistent
Use
irf mac-address persistent
to configure IRF bridge MAC persistence.
Use
undo irf mac-address persistent
to disable IRF bridge MAC persistence.
Syntax
irf mac-address persistent
{
always
|
timer
}
undo irf mac-address persistent
