Output queue aging   

This function is used to avoid the poor utilization of the switch. When a packet is stored 

in a switch for a long time, it will expire from the allowable time defined by the protocol 

and become a useless packet. To prevent these packets from wasting the bandwidth, 

this switch provide an option for the administrator to enable the queue aging function. 

 

Stride VLAN 

By selecting this function, the switch will forward uni-cast packets to the destination port, 

no matter whether destination port is in the same VLAN.   

 

IGMP Snooping 

 

When this function is enabled, the switch will execute IGMP snooping version 1 and 

version 2 without the intervention of CPU.   

 

The IGMP report and leave packets are automatically handled by the switch.
