61.2 circuit-failover
Commands:
circuit-failover {vlan<ID>| IFNAME} <value_reduced>
no circuit-failover
Function:
Configures the VRRPv3 monitor interface.
Parameters:
{vlan<ID>| IFNAME} is the name for the interface to be monitored.
<value_reduced> stands for the amount of priority decreased, the range value is from 1 to 253.
Command mode:
VRRPv3 Protocol Configuration Mode.
Default:
Not configured by default.
Usage Guide:
The interface monitor function is a valuable extension to backup function, which not only enable
VRRPV3 to provide backup function on router (or L3 Ethernet switch) fail, but also allow decreasing
the priority of a router (or L3 Ethernet switch) to ensure smooth implementation of backup function
when status of that network interface is down.
When this command is used, if the status of an interface monitored turns from up to down, then the
priority of that very router (or L3 Ethernet switch) in its Standby cluster will decrease (If the priority of
that value_reduced is higher than interface configuration, then the corresponding router is down, the
priority of interface in Backup decrease until 0), lest Backup cannot changes its status due to lower
priority than the Master when the Master fails. After the interface monitored turns up over again, the
priority of corresponding router (or L3 Ethernet switch) will restore in Backup.
Example:
Configuring VRRPv3 monitor interface to VLAN 2 and decreasing amount of priority to 10.
Switch(Config-router)# circuit-failover vlan 2 10
61.3 debug ipv6 vrrp
Command:
debug ipv6 vrrp [all | events | packet [recv | send]]
no debug ipv6 vrrp [all | events | packet [recv | send]]
Function:
Display the state change, message receiving and sending of a VRRPv3 backup group, the no
