Configuring A Port-Specific Load Sharing Mode; Configuring Irf Bridge Mac Persistence - HP 5130 EI series Configuration Manual

Configuring a port-specific load sharing mode

Before you configure a port-specific load sharing mode, make sure you have bound a minimum of one
physical interface to the IRF port.
To configure a port-specific load sharing mode for an IRF port:
Step
1. Enter system view.
2. Enter IRF port view.
3. Configure the port-specific
load sharing mode.

Configuring IRF bridge MAC persistence

By default, an IRF fabric uses the bridge MAC address of the master device as its bridge MAC address.
Layer 2 protocols, such as LACP, use this bridge MAC address to identify the IRF fabric. On a switched
LAN, the bridge MAC address must be unique.
To avoid duplicate bridge MAC addresses, an IRF fabric can change its bridge MAC address
automatically after the address owner leaves. However, the change causes temporary traffic disruption.
Depending on the network condition, enable the IRF fabric to retain or change its bridge MAC address
after the address owner leaves. Available options include:
irf mac-address persistent timer—Bridge MAC address of the IRF fabric is retained for 6 minutes
•
after the address owner leaves. If the address owner does not return before the timer expires, the IRF
fabric uses the bridge MAC address of the current master as its bridge MAC address. This option
avoids unnecessary bridge MAC address changes caused by device reboot, transient link failure,
or purposeful link disconnection.
irf mac-address persistent always—Bridge MAC address of the IRF fabric does not change after
•
the address owner leaves.
NOTE:
IRF fabrics cannot merge if they have the same bridge MAC address. If you use the removed bridge
MAC address owner as the master device in a new fabric, the bridge MAC of the new fabric is the
same as the old fabric. For the two IRF fabrics to merge, you must change the bridge MAC address of
the old IRF fabric.
undo irf mac-address persistent—Bridge MAC address of the current master replaces the original
•
bridge MAC address as soon as the owner of the original address leaves.
When you configure IRF bridge MAC persistence, follow these guidelines:
If ARP MAD or ND MAD is used, configure the undo irf mac-address persistent command to
•
enable immediate bridge MAC address change after the address owner leaves.
