config multicast_fdb
<macaddr>
−
The MAC address that will be added to the forwarding
table.
[add|delete]
−
Add will add the MAC address to the forwarding table.
Delete will remove the MAC address from the forwarding table.
<portlist>
−
Specifies a range of ports to be configured. The port list is
specified by listing the lowest slot number and the beginning port
number on that slot, separated by a colon. Then the highest slot
number, and the highest port number of the range (also separated by a
colon) are specified. The beginning and end of the port list range are
seperated by a dash. For example, 1:3 specifies slot number 1, port 3.
2:4 specifies slot number 2, port 4. 1:3-2:4 specifies all of the ports
between slot 1, port 3 and slot 2, port 4
−
in numerical order.
Restrictions
Only administrator-level users can issue this command.
Example usage:
To add multicast MAC forwarding:
DES6500:4#config multicast_fdb default 01-00-23-11-11-11
add 4:1-4:4
Command: config multicast_fdb default 01-00-23-11-11-11 add
4:1-4:4
Success.
DES-6500:4#
config fdb aging_time
Purpose Used to set the aging time of the forwarding database.
Syntax config fdb aging_time <sec 10-1000000>
Description The aging time affects the learning process of the switch. Dynamic
forwarding table entries, which are made up of the source MAC
addresses and their associated port numbers, are deleted from the
table if they are not accessed within the aging time. The aging time can
be from 10 to 1000000 seconds with a default value of 300 seconds. A
very long aging time can result in dynamic forwarding table entries that
are out-of-date or no longer exist. This may cause incorrect packet
forwarding decisions by the switch. If the aging time is too short
however, many entries may be aged out too soon. This will result in a
high percentage of received packets whose source addresses cannot
