Checking SNMP SET Errors

Occasionally, you may receive an SNMP SET error when you try to connect to a

router in dynamic mode. SET errors lock you out of the router for a period of time

(the default lockout time is 2 minutes). The router displays one of the following

SET error messages:

• SNMP General Set Error! Machine is currently locked by Manager (IP

Address)

• SNMP set error

The SNMP General Set Error message appears when an SNMP SET lockout

condition exists on a the target router.

Common causes for these errors include the following:

• Another person is connected to the router you are attempting to conﬁgure.

• An SNMP request from your Site Manager workstation timed out due to

trafﬁc conditions on the network.

• The SNMP community name that you speciﬁed for the SNMP request did not

allow write access to the desired router.

When you are locked out of the router, it may mean that the router rejected one or

more of your SET attempts, or you may need to modify part of your conﬁguration.

RMON, BootP, DHCP, and RARP Services.
