• Mac Address Aging Time—Select the length of time a learned MAC address remains 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
1,000,000 seconds.
NOTE: A very long aging time can result in out-of-date dynamic entries that may cause incorrect
packet filtering and forwarding decisions. A very short aging time may cause entries to be aged out
too soon, resulting in a high percentage of received packets whose source addresses cannot be
found in the address table, in which case the GbE Interconnect Switch will broadcast the packet to
all ports, negating many of the benefits of having a GbE Interconnect Switch.
• IGMP Snooping—Choose to enable or disable Internet Group Management Protocol
(IGMP) Snooping. IGMP Snooping enables the GbE Interconnect Switch to read IGMP
packets being forwarded through the GbE Interconnect Switch in order to obtain
forwarding information from them, such as which ports contain Multicast members.
• GVRP Status—Choose to enable or disable Group VLAN Registration Protocol (GVRP)
on the GbE Interconnect Switch. GVRP allows members to dynamically join VLANs.
• Telnet Status—Choose to enable or disable access to the GbE Interconnect Switch over
the network using the TCP/IP Telnet protocol.
• Web Status—Choose to enable or disable management of the GbE Interconnect Switch
over the Web.
• Group Address Filter Mode—Select one of the forwarding or filtering options to set the
IGMP filter mode for processing multicast packets.
• Scheduling Mechanism for CoS Queues—Choose one of the Class of Service queue
options. If you select Strict, then when the highest priority queue is full, those packets
will be the first to be forwarded. If you select RoundRobin, the forwarding is based on
the settings made on the Class of Service Configuration screen.
• Trunk Load Sharing Algorithm—Select one of the trunk load sharing options, Source
Addr, Destination Addr, or Both, to determine if load balancing decisions will be made
based on the source MAC address, destination MAC address, or both addresses.
• Backpressure— Select Enabled or Disabled to initiate or terminate traffic flow control
in and out of the switch.
After making your choices in Advanced Settings, click Apply.
NOTE: To save the configuration settings permanently, they must be entered into NVRAM using
the Save Changes option on the Maintenance menu. Refer to the section, “Saving Changes,”
earlier in this chapter.
