DES-3350SR Layer 3 Gigabit Switch
73
config multicast_fdb
Parameters
<vlan_name 32>
−
The name of the VLAN on which the MAC
address resides.
<macaddr>
−
The MAC address that will be added to the multicast
forwarding table.
[add | delete]
−
Add will add ports to the forwarding table. Delete
will remove ports from the multicast forwarding table.
§
<portlist>
−
Specifies a port or range of ports to be
configured.
Restrictions
Only administrator-level users can issue this command.
Example usage:
To add multicast MAC forwarding:
local>config multicast_fdb default 01-00-00-00-00-01 add 1:1-1:5
Command: config multicast_fdb default 01-00-00-00-00-01 add 1:1-1:5
Success.
local>
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table entries that are out-of-date or no longer exist.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 be found in the forwarding table,
in which case the switch will broadcast the packet to all ports,
negating many of the benefits of having a switch.
Parameters
<sec
10-1000000>
−
The aging time for the MAC address
forwarding database value. The value in seconds may be between
10 and 1000000 seconds. The default is 300 seconds.
Restrictions
Only administrator-level users can issue this command.
