SNMP Health Check Parameters (/cfg/slb/advhc/health <health check ID>/snmp/snmp) 
Command Syntax and Usage
oid
 
Sets the OID string to be sent.
comm
 
Sets the community string.
response [integer|string]
 
Sets the expected response and the expected overload response.
In the overload state, the real server maintains existing connections. New connections are not allocated to such a server, unless the /cfg/slb/group/maxconex command is enabled for the server group and the new connection belongs to an existing persistent session (with pbind set to clientip, sslid, or cookie).
Values:
*integer — Specifies the minimum maximum values expected in the SNMP response packet, and the minimum and maximum overload values.
The real server is moved to the overload state when the value in the real server response is within the range defined by the minimum and maximum overload values.
Valid range: 0 – 65535
Default: 0 (none)
*string — Specifies the string for the expected response, and the overload string.
The real server is moved to the overload state when the response string matches the defined overload string.
Maximum characters: 64
weight
 
Specifies whether the real server weights are adjusted dynamically based on the SNMP health check response.
Weights can be assigned to each real server. These weights can bias load balancing to give the fastest real servers a larger share of connections. A setting of 10 would assign the server roughly 10 times the number of connections as a server with a weight of 1.
Values:
*enable — The real server weights are adjusted dynamically based on the SNMP health check response.
*disable — The real server weights are not adjusted dynamically based on the SNMP health check response.
*invert — If the SNMP health check response returns a value lower than 100, Alteon adjusts the real server weight to 100 minus the returned value.
If the SNMP health check response returns a value of 100 or greater, Alteon sets the real server weight to 100.
Default: disable
cur
 
Displays the current configuration.
