mdc-operator 

Parameters 

irf-port

: Displays IRF port-specific load sharing modes. If you do not specify this keyword, the command 

displays the global load sharing mode for IRF links. 

member-id

/

port-number

: Specifies an IRF port number. The 

member-id

 argument represents an IRF 

member ID. The 

port-number

 argument represents the index number (1 or 2) of the IRF port on the 

member device. If you do not specify the 

member-id

 and 

port-number

 arguments, this command displays 

the load sharing mode used on each IRF port in the IRF fabric. 

Examples 

# Display the global load sharing mode for IRF links. In this example, because no user-defined global 
load sharing mode has been configured, the default global load sharing mode applies.  

<Sysname> display irf-port load-sharing mode 

irf-port Load-Sharing Mode: 

Layer 2 traffic: destination-mac address, source-mac address 

Layer 3 traffic: destination-ip address,  source-ip address 

Layer 4 traffic: destination-port,         source-port 

# Display the global load sharing mode for IRF links. In this example, because a global load sharing 
mode based on source and destination IP addresses have been configured, the configured mode 

applies.  

<Sysname> display irf-port load-sharing mode 

irf-port Load-Sharing Mode: 

  destination-ip address,  source-ip address 

# Display the load sharing mode of IRF-port 1/1. In this example, because neither port-specific load 

sharing mode nor user-defined global load sharing mode has been configured, the default global load 
sharing mode applies.  

<Sysname> display irf-port load-sharing mode irf-port 1/1 

irf-port 1/1 Load-Sharing Mode: 

Layer 2 traffic: destination-mac address, source-mac address 

Layer 3 traffic: destination-ip address,  source-ip address 

Layer 4 traffic: destination-port,         source-port 

# Display the load sharing mode of IRF-port 1/1. In this example, a load sharing mode based on source 
and destination MAC addresses has been configured on the port. 

<Sysname> display irf-port load-sharing mode irf-port 1/1 

irf-port1/1 Load-Sharing Mode: 

  destination-mac address, source-mac address 

# Display the load sharing mode used on each IRF port.  

<Sysname> display irf-port load-sharing mode irf-port 

irf-port1/1 Load-Sharing Mode: 

destination-mac address, source-mac address 

 

irf-port1/2 Load-Sharing Mode: 

Layer 2 traffic: destination-mac address, source-mac address 

Layer 3 traffic: destination-ip address,  source-ip address
