Snmp query timeout increase

Other Northbound Interfaces

Hi,

We are seeing snmpwalk entry timeout in a scale setup where there are lot of entries. From the snmp log, it says that when it times out, get_next_request is taking almost 70 sec. By the time backend responds, confd times out. Is it possible to tweak this timeout? I tried increasing snmp gw timeout value to 90sec. It does not help. Any pointers?

The timeout message comes from snmpwalk, not from confd. If you want to tweak snmpwalk’s timeout, you can use -r <NoOfRetries> or -t <RetryTimeout>.
