Command: config multicast_fdb default 01-00-00-00-00-01 
add 1-5 

 

Success. 

 

DES-3028P: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table entries that are out-of-date or no longer exist.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 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. 

Restrictions 

Only Administrator-level users can issue this command. 

Example usage: 

To set the fdb aging time: 

DES-3028P:4#config fdb aging_time 300 

Command: config fdb aging_time 300 

 

Success.
