Command History
Usage Guidelines Before you use this command to associate an SNMP context with a VPN, you must do the following:
• Issue the snmp-server context command to create an SNMP context
• Associate a VPN with a context so that the specific MIB data for that VPN exists in that context.
• Associate a VPN group with the context of the VPN using the snmp-server group command with
the context context-name keyword and argument.
SNMP contexts provide VPN users with a secure way of accessing MIB data. When a VPN is associated
wi
th a context, MIB data for that VPN exists in that context. Associating a VPN with a context helps
enable service providers to manage networks with multiple VPNs. Creating and associating a context
with a VPN enables a provider to prevent the users of one VPN from accessing information about users
of other VPNs on the same networking device.
context-name Name of the SNMP VPN context, up to 32 characters.
