Snmp Community Operation in a Stack

Configuring Advanced Features

Stack Management

Community Membership

In the default stacking configuration, when a Candidate joins a stack, it automatically becomes a Member of any SNMP community to which the Commander belongs, even though any community names configured in the Commander are not propagated to the Member’s SNMP Communities listing. However, if a Member has its own (optional) IP addressing, it can belong to SNMP communities to which other switches in the stack, including the Commander, do not belong. For example:

Commander Switch

IP Addr: 12.31.29.100

Community Names:

–blue

–red

Member Switch 1

IP Addr: 12.31.29.18

Community Names:

– public (the default)

Member Switch 2

IP Addr: None

Community Names:

– none

Member Switch 3

IP Addr: 12.31.29.15

Community Names:

–public (the default)

–gray

•The Commander and all Members of the stack belong to the blue and red communities. Only switch 3 belongs to the gray community. Switches 1, 2, and 3 belong to the public community

•If Member Switch 1 ceases to be a stack Member, it still belongs to the public SNMP community because it has IP addressing of its own. But, with the loss of stack Membership, Switch 1 loses membership in the blue and red communities because they are not specifically configured in the switch.

•If Member Switch 2 ceases to be a stack Member, it loses membership in all SNMP communities.

•If Member Switch 3 ceases to be a stack Member, it loses membership in the blue and red communities, but—because it has its own IP addressing—retains membership in the public and gray communities.

SNMP Management Station Access to Members Via the Commander.

To use a management station for SNMP Get or Set access through the Commander’s IP address to a Member, you must append @sw<switch number> to the community name. For example, in figure 9-37,you would use the following command in your management station to access Switch 1’s MIB using the blue community:

snmpget <MIB variable> 10.31.29.100 blue@sw1

Note that because the gray community is only on switch 3, you could not use the Commander IP address for gray community access from the management station. Instead, you would access switch 3 directly using the switch’s own IP address. For example:

snmpget <MIB variable> 10.31.29.15 gray
