N_Port also go offline. Once the number of SCNs drops below the set threshold, the port is deemed
reliable again and the N_Port and mapped VF_Ports go back online.
The default threshold is 25 SCNs per 5 minutes. You can set from 10 to 100 SCNs per 5 minutes.
Modify default threshold of SCNs counted in 5 minutes using the counter reliability value command
while in ag command mode.
Setting and displaying the reliability counter for N_Port monitoring
You can set the reliability count of static change notifications (SCNs) counted during a five-minute
period before the link between a N_Port on a VDX Switch in Access mode and an F_Port on a FC fabric
is considered unreliable.
Access Gateway mode must be enabled for this procedure to succeed.
To set the reliability count, use the counter reliability value command while in ag configuration mode
for the switch. The default value is 25 SCNs per 5 minutes. You can set from 10 to 100 SCNs per 5
minutes.
1. Enter the configure terminal command to enter global configuration mode.
switch# configure terminal
2. Enter the rbridge-id id command to enter RBridge ID mode for the specific switch.
switch(config)# rbridge-id 2
3. Enter the ag command to enter Access Gateway configuration mode.
switch(config-rbridge-id-2)# ag
4. Enter the counter reliability value command to change the counter value.
switch(config-rbridge-id-2-ag)# counter reliability 50
5. Enter the counter reliability command without a value to display the current reliability counter. In the
following example, a counter value of 50 is returned.
switch(config-rbridge-id-2-ag)# counter reliability
() (50)
