Restricting SNMP on an interface

tzachi.slav · ‎03-29-2006

Dear Experts,

Our network router has 4 serial interfaces and 2 Ethernet interfaces.

The router is working in SNMP V2 with SNMP based application.

One of the Ethernet interfaces is restricted. Thus, i do not want it to be polled VIA SNMP.

How can i not notify my management station about the second Ethernet interface (the management application will think that there is only 1 Ethernet interface)?

Thank you very much.

Use SNMP View:

Thank you very much for the fast response.

However, i don't understand how "SNMP view" will disable polling of a specific interface in the router?

The OID tree for your device will have a section that describes the interface you want blocked and all it's characteristics. If you MIBwalk the device, you will discover the specific OIDtree "branch" which applies to the particular interface. You then plug that ASN.1 subtree into "oid-tree" field of the command "snmp-server view view-name oid-tree excluded"

Hope this helps, please rate helpful posts.
