Access Gateway policies
2
The ports mapped to N_2 (F_1, F_3, and F_4) fail over to N_3 and N_4. Note that the F_Ports
are evenly distributed to the remaining online N_Ports and that the F_2 port did not participate
in the failover event.
FIGURE 4 Example 1 and 2 Failover policy behavior
Enabling the Failover policy
1. Connect to the switch and log in as admin.
2. Enter the ag command with the
--failovershow <n_portnumber> operand to display the
failover setting.
switch:admin> ag --failovershow 13
Failover on N_Port 13 is not supported
3. Enter the ag command with the --failoverenable <n_portnumber> operand to enable failover.
switch:admin> ag --failoverenable 13
Failover policy is enabled for port 13
