Advanced Settings

After making the desired advanced setting Layer 2 changes, click Apply to let them take effect.
The information in the window is described as follows:
•
Auto-Logout [Never] – This sets the time the interface can be idle before the switch automatically
logs-out the user. The options are 2 minutes, 5 minutes, 10 minutes, 15 minutes, or Never.
•
MAC Address Aging Time [10-2100(sec)] [300 ] – This field specifies the length of time a learned
MAC Address will remain in the forwarding table without being accessed (that is, how long a learned
MAC Address is allowed to remain idle). The Aging Time can be set to any value between 10 and
2100 seconds.
Note: A very long Aging Time can result with the out-of-date Dynamic Entries that may cause
incorrect packet filtering/forwarding decisions. A very short aging time may cause entries to
be aged out to soon, resulting in a high percentage of received packets whose source
addresses cannot be found in the address table, in which case the switch will broadcast the
packet to all ports, negating many of the benefits of having a switch.
•
IGMP Snooping [Disabled] – This setting enables Internet Group Management Protocol (IGMP)
Snooping, which enables the switch to read IGMP packets being forwarded through the switch in
order to obtain forwarding information from them (learn which ports contain Multicast members).
•
GVRP Status [Enabled] – Group VLAN Registration Protocol is a protocol that allows members to
dynamically join VLANs. This is used to enable or disable GVRP on the switch
•
Scheduling Mechanism for CoS Queues [Strict] – There are two Class of Service queue options,
RoundRobin and Strict. If Strict is selected, when the highest priority queue is full, those packets will
be the first to be forwarded. If RoundRobin is selected, the forwarding is based on the settings made
on the Class of Service Configuration screen.
•
Trunk Load Sharing Algorithm [Source Addr] – The trunk load sharing options are Destination
Addr, Src & Dest Addr, and Source Addr.
•
Year/Month/Date – This allows you to set the year, month, and date.
•
Hour/Minute/Second – This allows you to set the hour, minute, and second.
