mode can cause temporary loops in your network, but the STP will eliminate them.
Fastlink is best used on end node ports, i.e. ports connected to PCs or servers, to avoid
network loops.
• Bridge Priority: Priority setting of this switch in the Spanning Tree.
• Bridge Max Age: Amount of time before a configuration message is discarded by the
system.
• Bridge Hello Time: Interval between configuration messages sent by the Spanning Tree
algorithm.
• Bridge Forward Delay: Amount of time system spends in 'learning' and 'listening' states.
• Path Cost: The switch uses this to determine which port is the forwarding port. All other
factors equal, the path with the lowest cost to the root bridge will be the active path.
• Path Priority: STP bases on this to determine the port to use for forwarding. The port with
the lowest number has the highest priority.
Switch> Advanced> SNMP
SNMP page allows you to limit the IP address which can access the MIB of the switch and
which the switch will send trap to. The switch will only respond to requests from computers
with the IP address in the list. You can also select the traps which the switch will send to the
hosts in the following trap events. The setting of a host will not be active until it is set to
“Enable” in the Admin field.
Trap Events :
• Device bootup - The switch generates an SNMP trap when it reboots.
• Authentication fail - The switch generates an SNMP trap when a host tries to gain access
to the switch but the host's IP is not in the SNMP host table.
• Link Up/Down - The switch generates an SNMP trap when one of its ports changes its link
status.
Switch> Advanced> IGMP Snooping
IGMP Snooping
IGMP Function: Enabling IGMP snooping allows individual ports to detect IGMP queries,
report packets, and manage IP multicast traffic through the switch. Disabling IGMP snooping
has the switch forward traffic, disregarding any IGMP requests.
Block Unknown Multicast Address: The entries of multicast address table in the switch can be
obtained by learning with IGMP snooping or by the static groups of user’s input. Enabling the
function allows the switch to discard the multicast packets whose destination MAC address
does not exit in the multicast address table. Otherwise, the packets will be flooded
