CHGCOMSNMP (Change Community for SNMP)

CHGCOMSNMP Command syntax diagram

 

Purpose

The Change Community for SNMP (CHGCOMSNMP) command changes an SNMP community profile in the SNMP agent community list. An SNMP agent uses a community profile to determine whether or not to honor a request sent by an SNMP manager. The community profile consists of a community name, an object access specification, and a list of the SNMP managers that are part of the community. The combination of the community name (COM) and the translate to ASCII community (ASCIICOM) parameters defines a community.

 

Required Parameters

COM

Specifies the name of the SNMP community being changed. The community must already exist in the SNMP agent community list. You can define an SNMP community using the Add Community for SNMP (ADDCOMSNMP) command.

community-name: Specify the name of the SNMP community being changed. The name may contain characters that cannot be displayed.

 

Optional Parameters

ASCIICOM

Specifies whether the community name is translated to ASCII characters before it is compared with the community name specified in a request from an SNMP manager. This parameter is used in combination with the community name to determine the community to be changed. If this parameter is not specified and two communities have the same name but different ASCIICOM parameter values, the community that is changed is the community with ASCIICOM set to *YES.

*YES: The community name is translated to ASCII characters before it is compared with a community name specified by an SNMP manager.

*NO: The community name is not translated to ASCII characters before it is compared with a community name specified by an SNMP manager.

INTNETADR

The internet addresses of the SNMP managers that are part of this community.

*SAME: The value does not change.

*ANY: Allow any SNMP manager to be part of this community.

manager-internet-address: Specify the internet address of the SNMP manager. The internet address is specified in the form nnn.nnn.nnn.nnn, where nnn is a decimal number ranging from 0 through 255. An internet address is not valid if it has a value of all binary ones or all binary zeros for the network identifier (ID) portion or the host ID portion of the address. If the internet address is entered from a command line, the address must be enclosed in apostrophes. Up to 300 unique internet addresses may be specified. The same internet address may appear in more than one community profile.

OBJACC

Specifies the object access for the community.

*SAME: The value does not change.

*SNMPATR: The object access defined with the Change SNMP Attributes (CHGSNMPA) command is used for this community.

*READ: Allow SNMP managers that are part of this community to read all management information base (MIB) objects. Modification of MIB objects by SNMP managers is not permitted.

*WRITE: Allow SNMP managers that are part of this community to change all MIB objects that can be changed. Specifying *WRITE implies *READ access.

*NONE: Do not allow SNMP managers that are part of this community to access any MIB objects.

LOGSET

Specifies whether Set requests from SNMP managers in this community are logged in journal QSNMP in library QUSRSYS.

*SAME: The value does not change.

*SNMPATR: The value defined with the Change SNMP Attributes (CHGSNMPA) command is used for this community.

*YES: Set requests are logged.

*NO: Set requests are not logged.

LOGGET

Specifies whether get requests and get-next requests from SNMP managers in this community are logged in journal QSNMP in library QUSRSYS.

*SAME: The value does not change.

*SNMPATR: The value defined with the Change SNMP Attributes (CHGSNMPA) command is used for this community.

*YES: Get requests and get-next requests are logged.

*NO: Get requests and get-next requests are not logged.

Example for CHGCOMSNMP

CHGCOMSNMP   COM(ENDICOTT)   INTNETADR(*ANY)
  OBJACC(*READ)

This command changes community ENDICOTT to have an object access of read and to allow any SNMP manager to read the MIB objects on this system. All of the other community values are unchanged.
