Excluding A Port From The Shutdown Action Upon Detection Of Multi-Active Collision; Recovering An Irf Fabric - HP FlexFabric 5700 series Configuration Manual

Step
10. Assign the interface an IP
address.
11. Enable ND MAD.
Excluding a port from the shutdown action upon detection of
multi-active collision
CAUTION:
Do not exclude a VLAN interface and its Layer 2 ports from the shutdown action if the Layer 2 ports are
distributed on multiple member devices. The exclusion introduces IP collision risks because the VLAN
interface might be up on both active and inactive IRF fabrics.
By default, all ports (except the console and IRF physical interfaces) shut down automatically when the
IRF fabric transits to the Recovery state.
You can exclude a network port from the shutdown action for management or other special purposes. For
example:
Exclude a port from the shutdown action so you can Telnet to the port for managing the device.
•
Exclude a VLAN interface and its Layer 2 ports from the shutdown action so you can log in through
•
the VLAN interface.
To configure a port to not shut down when the IRF fabric transits to the Recovery state:
Step
1. Enter system view.
2. Configure a network port to
not shut down when the IRF
fabric transits to the
Recovery state.

Recovering an IRF fabric

When the failed IRF link between two split IRF fabrics is recovered, all member devices in the inactive IRF
fabric automatically join the active IRF fabric as subordinate members. The network ports that have been
shut down by MAD automatically restore their original physical state, as shown in
Command
ipv6 address
{ ipv6-address/pre-length | ipv6
address pre-length }
mad nd enable
Command

Remarks
By default, no IPv6 address is
assigned to any VLAN interface.
By default, ND MAD is disabled.
Remarks
N/A
By default, all network ports on a
Recovery-state IRF fabric are shut
down, except for the IRF physical
interfaces and console port.
