20 The maximum time (in seconds) a device can wait without
receiving a configuration message before attempting to
reconfigure. All device ports (except for designated ports)
should receive configuration messages at regular intervals. Any
port that ages out STA information (provided in the last
configuration message) becomes the designated port for the
attached LAN. If it is a root port, a new root port is selected
from among the device ports attached to the network.
The minimum value is the higher of 6 or [2 x (Hello Time + 1)].
The maximum value is the lower of 40 or [2 x (Forward Delay -
1)].
GMRP Disabled GARP Multicast Registration Protocol (GMRP) allows network
devices to register endstations with multicast groups.
If GMRP is globally enabled for the switch, then you can
individually enable or disable GMRP for a specific port. See
“VLAN Port Configuration” on chapter 2.
IGMP and IGMP Snooping also provide multicast filtering. For
multilayer mode, the full IGMP protocol set is automatically
enabled / disabled along with DVMRP. (See “IGMP Protocol”
on chapter 4, “Configuring DVMRP” on chapter 2 and
“Configuring IGMP Snooping” on chapter 2.)
GVRP Disabled GARP VLAN Registration Protocol (GVRP) defines a way for
switches to exchange VLAN information in order to register
VLAN members on ports across the network. This function
should be enabled to permit automatic VLAN registration, and
to support VLANs which extend beyond the local switch.
If GVRP is globally enabled for the switch, then you can
individually enable or disable GVRP for a specific port. See
“VLAN Port Configuration” on chapter 2.
Priority
Threshold*
4 This switch supports Quality of Service (QoS) by using two
priority queues, with Weighted Fair Queuing for each port. Up
to 8 separate traffic classes are defined in IEEE 802.1p.
Therefore, any packets with a priority equal to or higher than
this threshold are placed in the high priority queue.

Aging Time
300 Timeout period in seconds for aging out dynamically learned
forwarding information.
Range: 10 - 415 seconds
* You can use “VLAN Port Configuration” on chapter 2 to configure the default priority
for each port.
