fcTimerRatov
Module: CISCO-VSAN-MIB
OID (symbolic): CISCO-VSAN-MIB::fcTimerRatov
OID (numeric): 1.3.6.1.4.1.9.9.282.1.4.1
Node type: OBJECT-TYPE
Type: CiscoMilliSeconds
Access: read-write
Description: The Resource_Allocation_Timeout Value used for FxPorts as the timeout value for determining when to reuse an NxPort resource such as a Recovery_Qualifier. It represents E_D_TOV (fcTimerEdtov) plus twice the maximum time that a frame may be delayed within the Fabric and still be delivered.
Note that all switches in a fabric should be configured with the same value of this timeout.
What is fcTimerRatov?
This read-write timer, expressed in milliseconds, sets the Resource_Allocation_Timeout Value (R_A_TOV) that FxPorts on this switch use to decide when it is safe to reuse an NxPort resource such as a Recovery_Qualifier. An administrator must keep this value consistent across every switch in the fabric, since a mismatch can cause resource reuse conflicts during fabric recovery. For example, if one switch in the fabric has a shorter fcTimerRatov than the rest, it might free up port resources for reuse before its peers consider it safe to do so.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.282.1.4.1 snmpwalk -v2c -c public <target> CISCO-VSAN-MIB::fcTimerRatov
Get a specific instance (index 1):

Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.9.9.282.1.4.1.1 s <value>
