Path Cost
(0 – 65535) - It is used to determine the best path between devices when there is looping. Lower
values will be forwarded and should be assigned to ports with fast connections. Higher values will be blocked
and should be assigned to ports with slow connections. The suggestion values are 100 (50~600) for 10M, 19
(10~60) for 100M and 4 (3~10) for 1000M connections.
Spanning Tree Port Priorities
This option will allow you to change the spanning tree path priorities.

.
3. Highlight the port that you want to change and press
Enter
.
4. Enter the new path priorities in the prompt screen and press
Enter
. The value is from 0 to 255. A low value
gives the port a greater likelihood of becoming a Root port.
5. Press Esc to return to the desired screen.
Port Priority
(0-255) - If the path cost for all ports on a switch is the same, the port with the highest priority
(lowest value) will be forwarded when there is looping. If more than one port has the same high priority, the port
with lowest port number will be forwarded.
SNMP
SNMP allows you to view and change all SNMP-related information. The 2600M supports the SNMP agent
function and you can configure SNMP settings (community name, trap host, trap events, etc). SNMP is enabled
by default. To change the configuration:

Other Protocols
The
Other Protocols
Menu allows you to enable and disable
GVRP
and
IGMP
protocols. The GVRP (GARP
VLAN Registration Protocol) protocol can handle the VLAN activity inside the switch and between switches.
The IGMP (Internet Group Management Protocol) protocol can handle IP multicast activity in the network. This
switch supports IGMP Snooping operation for IP multicast packets filtering and forwarding. GVRP and IGMP
are disabled by default.
GVRP
- Enable or disable GVRP operation
IGMP
- Enable or disable IGMP operation
Passive
- Passively snooping on the IGMP Query and IGMP Report packets transferred between IP
Multicast Routers and IP Multicast host groups to learn IP Multicast group members
Active
- Actively sending IGMP Query messages to solicit IP Multicast group members
Concentration
– IGMP snooping operation in a concentration VLAN configuration sets multicast group
