Clearing IS-IS information
When the level-1 or level-2 options are used, the SPF calculation is only triggered for the specified
level. If not specified, the SPF calculation will be triggered for both.
Clearing IS-IS information
To clear the IS-IS information that the Brocade device has accumulated since the last time you
cleared information or reloaded the software, use either of the following methods.
To clear IS-IS information, enter the clear isis all command at any level of the CLI except the User
EXEC level.
Brocade# clear isis all
This command clears all the following:
• Neighbors (closes the Brocade device’s adjacencies with its IS-IS neighbors)
• Routes
• PDU statistics
• Error statistics
Syntax: clear isis all | counts | neighbor | route [ip-address subnet-mask | ip-address/prefix] |
traffic
The all parameter clears all the IS-IS information. Using this option is equivalent to entering
separate commands with each of the other options.
The counts parameter clears the error statistics.
The neighbor parameter closes the Brocade device’s adjacencies with its IS-IS neighbors and
clears neighbor statistics.
The route [ip-address subnet-mask | ip-address/prefix ] parameter clears the IS-IS route table or
the specified matching route.
The traffic parameter clears the PDU statistics.
NOTE
The traffic option also clears the values displayed in the show isis interface command’s Control
Messages Sent and Control Messages Received fields.
The neighbor option of the clear isis command has been enhanced as described in the following:
Syntax: clear isis neighbor all [ethernet slot/port | pos slot/port | tunnel tunnel-id | ve
port-number]
The all option directs the router to clear all neighbors on all IS-IS interfaces or clear all neighbors on
an interface specified using one of the following options:
ethernet slot/port – clears all IS-IS neighbors on the specified Ethernet interface.
pos slot/port – clears all IS-IS neighbors on the specified POS interface.
ve port-no – clears all IS-IS neighbors on the specified virtual interface.
tunnel tunnel-port – clears all IS-IS neighbors on the specified tunnel interface.
Syntax: clear isis neighbor sys-id [ethernet slot/port | pos slot/port | tunnel tunnel-id | ve
port-number]
