Ethernet SNMP Module Installation and Reference Guide ( J2603B) 1995-10

For Port Security: The security violations are indicated by the Security
LED and the LED for the affected port blinking simultaneously, and the
intruder’s station address being added to the Status command screen for the
affected port. Security violations occur when a non-authorized address is
detected on a port and at least one of the intruder prevention parameters
(Send Alarm or Disable Port) is set to YES.
For Network Management Security: The security violations are
indicated by the Security LED flashing and the violating network
management station’s address being displayed on the Status command
screen.
A network management security violation occurs when a network
management station that is not on the authorized management station list
attempts to issue SNMP “set” commands to the hub, or when a network
management station uses an invalid password (SNMP community name) to
access the hub.
See the Managers command description, earlier in this chapter, for
information on the authorized management station list. By default, all
network management stations are allowed to manage the hub. Under this
configuration, network management security violations will not occur.
Notes If the port was disabled because of a security violation
(Disable Port = YES), to re-enable the port you must enter the port ON
command for that port.
The Security Clear command does not remove the cause of the security
violation, for example the wrong device being attached to a port. Until
the cause is removed, the violation can reoccur immediately after
issuing the
SE CL command. It may appear as if the violation indication
was never cleared.
