Configuring the SNMP Server on the JunosE Router
Access to the SNMP server on the router by an SNMP client is governed by a proprietary SNMP community table. This table identifies communities that have read-only, read-write, or administrative permission to the SNMP Management Information Base (MIB) stored on a particular server.
When an SNMP server receives a request, the server extracts the client’s IP address and the community name. The SNMP server searches the community table for a matching community.
If a match is found, its access list name is used to validate the IP address.
If the access list name is null, the IP address is accepted.
If an invalid IP address results, an SNMP authentication error is sent to the SNMP client.
If a match is not found, an SNMP authentication error results.
To configure the SNMP agent on the JunosE router:
Switch to the virtual router for which you want to create an SRC client.host1#(config)virtual-router <vrName>
Enable the SNMP agent.host1:<vrName>#(config)snmp-server
Configure at least one authorized SNMP read-write community (SNMPv1/v2c), which provides SNMP client access.host1:<vrName>#(config)snmp-server community boston rw
(Optional) Configure a read-only community.host1:<vrName>#(config)snmp-server public ro
