Figure 12 IRF split 

 

 

# Verify that BFD MAD detects the split and displays IRF link state and member device failure 
messages. The following is the sample output from IRF 1: 

%Jan  1 05:19:10:176 2018 H3C STM/3/STM_LINK_STATUS_DOWN: IRF port 2 is down.    

%Jan  1 05:19:10:184 2018 H3C IFNET/3/PHY_UPDOWN: Ten-GigabitEthernet1/0/53 link status 

is down.                                                                 

%Jan  1 05:19:10:184 2018 H3C IFNET/3/PHY_UPDOWN: Ten-GigabitEthernet1/0/54 link status 

is down.                                                                 

%Jan  1 05:19:10:176 2018 H3C STM/3/STM_LINK_STATUS_DOWN: IRF port 1 is down.    

%Jan  1 05:19:10:184 2018 H3C IFNET/3/PHY_UPDOWN: Ten-GigabitEthernet2/0/51 link status 

is down.                                                                 

%Jan  1 05:19:10:184 2018 H3C IFNET/3/PHY_UPDOWN: Ten-GigabitEthernet2/0/52 link status 

is down.                                                                 

%Jan  1 05:19:10:186 2018 H3C DEV/3/BOARD_REMOVED: Board is removed from Slot 3, type is 

MAIN_BOARD_TYPE_54QT.       

%Jan  1 05:19:10:186 2018 H3C DEV/3/BOARD_REMOVED: Board is removed from Slot 4, type is 

MAIN_BOARD_TYPE_54QT.       

%Jan  1 00:40:22:534 2018 H3C BFD/5/BFD_CHANGE_FSM: Sess[192.168.2.1/192.168.2.3, 
LD/RD:33/33, Interface:Vlan1000, SessType:Ctrl, LinkType:INET], Sta: DOWN->INIT, Diag: 
0    

%Jan  1 00:40:22:791 2018 H3C BFD/5/BFD_CHANGE_FSM: Sess[192.168.2.1/192.168.2.3, 
LD/RD:33/33, Interface:Vlan1000, SessType:Ctrl, LinkType:INET], Sta: INIT->UP, Diag: 0 

%Jan  1 00:40:27:962 2018 H3C BFD/5/BFD_CHANGE_FSM: Sess[192.168.2.1/192.168.2.3, 

LD/RD:33/33, Interface:Vlan1000, SessType:Ctrl, LinkType:INET], Sta: UP->DOWN, Diag: 1 

The output shows that the BFD session was up for a short time after the IRF split. Because the 
master device in IRF 1 has a lower member ID than the master device in IRF 2, BFD MAD then 
changed IRF 2 (Device C and Device D) to the Recovery state. The BFD session was down after 
BFD MAD shut down all service interfaces on Device C and Device D, except for the IRF physical 
interfaces and the service interfaces excluded from the MAD shutdown action. 

# Log in to IRF 2, and verify that the IRF fabric is in Recovery state.

Excluded ports(can not be configured):
