When the secondary port takes over, the port status shows Port 13,
the primary, as
Disabled/RL ; and Port 1, the secondary, as
Normal/RL .
To configure Check and return to primary timer :
The value you enter here has no effect if the primary port’s failure is due
to loss of link.
When the primary port is autopartitioned or is not receiving data, the
secondary port becomes enabled. Within the period you specify here, the
software does not check the primary port.
The timer indicates how long you want the secondary port to remain
enabled before checking if the primary port can receive data again or is no
longer partitioned. The default is 60 seconds.
This parameter provides you the flexibility to adapt to your requirements.
For example, you may base the checking time on how long it takes for
someone to fix the problem once the SNMP trap is received. This may be
5
minutes on typical days. If you know how long a primary port cannot
receive data because this port services an area in your building that is
being remodeled for two days, you want this timer value to encompass or
even exceed two days; but once this temporary condition goes away, you
can reconfigure the timer back to your standard, routine value.
1. Enter C to get the next screen.
2. Enter a value from 0-65,535 seconds.
NOTE
If your Check and return to primary timer is 0 and the primary port
fails, the secondary port takes over indefinitely. You must manually enable
the primary port through the
Port status menu.
To configure Resample timer :
The value you enter here has no effect if the primary port’s failure is due
to loss of link.
This timer indicates how long you want the software to test if the primary
port is able to receive data or is no longer partitioned. This timer begins
once the
Check and return to primary timer has expired (five
minutes based on the previous example). If the test shows that the
primary port is still not receiving data or is still partitioned, the secondary
port remains enabled. While sampling the primary port, the secondary
port cannot transmit packets received. To minimize packet loss, you may
want to enter a very low value. The default is 200 milliseconds.
1. Enter D to get the next screen.
2. Enter a value from 100-65,535 milliseconds.
After entering the above values, you are taken back to the Port
Configuration screen.
