Feature Operation for BPDU Cop
Manual Change
TIMEOUT = n
(0..2048) made by User
n = 0 None
(Auto-recovery
disabled)
n = 1..2048 None
(Auto-recovery
enabled)
n = 1..2048 User changes BPDU-
COP to N
n = 0 User changes BPDU-
COP to N
n = 1..2048 User changes n to 0
n = 0 User changers to a non-
zero value
n = 1..2048 User changes n to
another value
Configuring BPDU Cop
Result
If there is an unexpected BPDU, feature is
activated. The interface is disabled and must
be re-enabled by the user
If there is an unexpected BPDU, feature is
activated. After n minutes, the system will
re-enable the interface.
The fault is cleared immediately (interface is
re-enabled) by the system, but the feature is
now disabled.
The fault is not cleared (user must re-enable
interface), and the feature is now disabled.
Fault is not cleared (user must re-enable
interface), and the fault will not clear auto-
matically the next the feature is invoked.
Auto-recovery is being invoked, and once
the command is accepted the system will
wait n minutes and re-enable the interface.
The previous value is used for system
recovery, and the new value is used the next
time
