R3303-HP HSR6800 Routers IRF Command Reference

21
Usage guidelines
MAD action is not configurable for IRF physical ports.
When MAD detects that an IRF fabric has split into two or more identical active IRF fabrics, only the IRF
fabric whose master has the lowest member ID among all the masters can still forward data traffic. MAD
changes its status to Recovery on all the other IRF fabrics and shuts down all their physical ports except
the physical IRF ports and those manually configured to not shut down.
If a port must be kept in up state for special purposes such as Telnet connection, exclude it from the
shutdown action. To avoid problems, HP recommends not excluding any ports except the ports used for
Telnet and MAD.
The ports that have shut down by MAD come up when the member devices reboot to join the recovered
IRF fabric. If auto recovery fails because the current master fails or any other exception occurs, use the
mad restore command to manually recover the member devices and bring up the ports.
Examples
# Exclude Ethernet 2/0/5/1 from being shut down when the MAD status transitions to Recovery.
<Sysname> system-view
[Sysname] mad exclude interface ethernet 2/0/5/1
mad ip address
Use mad ip address to assign a MAD IP address to an IRF member on a VLAN interface for BFD MAD.
Use undo mad ip address to delete a MAD IP address.
Syntax
mad ip address ip-address { mask | mask-length } member member-id
undo mad ip address ip-address { mask | mask-length } member member-id
Default
No MAD IP address is configured on any VLAN interface.
Views
VLAN interface view
Default command level
3: Manage level
Parameters
ip-address: Specifies an IP address in dotted decimal notation. This IP address is bound to an IRF member
for BFD detection and is called a "MAD IP address."
mask: Specifies a subnet mask in dotted decimal notation.
mask-length: Specifies a subnet mask in length, in the range of 0 to 32.
member member-id: Specifies an IRF member ID.
Usage guidelines
To use BFD MAD, you must configure a MAD IP address on a BFD MAD enabled VLAN interface for each
IRF member, and make sure all the MAD IP addresses are on the same subnet.
