Switching Database Commands
add-lt-addr
Usage:
add-lt-entry <mac_address> {lock-off|lock-on} <dport>
Adds a learn table entry to the switching database. The command parameters are
described at the beginning of this chapter.
Note that
dport
is a decimal number representing the number of the destination port.
get-lt-age
Displays the switching database aging time in seconds. The aging time is the timeout
period for aging out dynamically learned forwarding information entries. An entry
whose MAC address does not appear in the source field of an incoming packet for a
period equal to the aging time is discarded. The default value for the aging time is 300
seconds.
SYS_console> get-lt-age
The running aging time is: 300 seconds
set-lt-age
Usage:
set-lt-age {run|nvram|all} <aging_time>
Lets you modify the switching database aging time. The change may be done:
•
In the running database so that the new value is used immediately.
•
In the NVRAM, meaning that the change will occur only in the next session.
•
In both the running and the NVRAM databases.
The
aging_time
is in seconds. The factory default value is 300 seconds. Use a lower
value if the number of active workstations at a given moment is larger than the size of
the switching database. The aging time can be anywhere between 10 and 11,000
seconds.
SYS_console> set-lt-age run 280
Aging Period update in the running database OK
SYS_console> set-lt-age all 100
Aging Period update in NVRAM OK
Aging Period update in the running database OK
