Creating a community

Create a community to use in forming a relationship between an SNMP agent and one or more SNMP managers. You require SNMP community strings to access the system using an SNMP-based management software.

Procedure

Enter Global Configuration mode:

enable

configure terminal
Create a community:
snmp-server community WORD<1-32> [group WORD<1-32>] [index WORD<1-32>] [secname WORD<1-32>]
Important
- The group parameter is only required if you created a new user group using the procedure in Creating a new user group. If you use any of the default groups, the secname automatically links the community to its associated group so there is no need specify the group in this command.
- If you do create a new group, use the snmp-server community command to create an SNMP community with a new security name and link it to the new group you created. There is no separate command to create a security name (secname). You use the snmp-server community command. The security name is the key to link the community name to a group.
- You cannot use the @ character or the string :: when you create community strings.

Example

In the following example, the community name is anewcommunity, the index is third, and the secname is readview. There is no group specified because this is a default public/read only group.

Switch:1>enable

Switch:1#configure terminal

Switch:1(config)#snmp-server community anewcommunity index third secname readview
