#### Meaning

Table 30 lists the show icr-partition command output fields.

Table 30: show icr-partition Output Fields

Field Name | Field Description
--- | ---
ICR Partition ID | Identifier for the ICR partition.
ICR Partition State | State of the ICR partition: Master—ICR partition that accepts subscriber login requests. Backup—ICR partition that does not accept subscriber login requests. Dormant—When the IP address or virtual router is forcibly deleted, or if the lower interface is not available, the ICR partition moves to the Dormant state. The dormant ICR partition does not accept subscriber login requests. Note: The state of the ICR partition depends on the associated VRRP instance.
ICR Partition Grouping Criterion | Grouping option for the subscribers. Possible options: S-VLAN and VLAN. The default grouping option is S-VLAN.
SVLAN | S-VLAN identifier for the interface.
VLAN | VLAN identifier for the interface. Any indicates that the VLAN ID is a wildcard and you can specify any configured VLAN ID with the associated S-VLAN ID.
control-interface | Controls the state of the corresponding subinterfaces (up/AdminDown) based on the state of the partition (master or backup). If the subinterfaces are part of the backup partition, the router changes the state of all the subinterfaces to AdminDown. You can also block all traffic on the backup partition. However, the router does not block VRRP advertisements as long as VRRP is running on a separate interface. Possible states: enabled or disabled. If the status is enabled, the router changes the state of the subinterface based on the state of the partition. If the status is disabled, the router does not control the state of the corresponding subinterface.
vrrp-mac | Configures the interface to use the default MAC address instead of the VRRP MAC address. Possible states: enabled or disabled. If the status is enabled, the interface uses the VRRP MAC address; otherwise, the interface uses the default MAC address.
advertise-mac | Enables the interface to transmit GARP advertisments when the partition moves from backup state to master state. Possible states: enabled or disabled. If the status is enabled, the interface transmits GARP advertisements; otherwise, the interface does not transmit GARP advertisements.
