Ageing Time (Secs)
0
/
60 ... 1000000
Allows you to specify the ageing time (in seconds) for all learned entries
in the Switch Database of the stack; the default time is 1800 seconds (30
minutes). If you specify an ageing time of 0, the ageing process is
disabled and the learned entries become non-ageing learned entries. For
more information about the Switch Database, see
“What is the Switch
Database?”
on
page 72
.
FastIP
Enabled
/
Disabled
Allows you to specify whether the stack uses FastIP to reduce the load on
routing devices when there is a large amount of inter-VLAN traffic on
your network. FastIP requires your stacks to support IEEE 802.1Q
learning; consequently, if you set the FastIP listbox to enabled, the
802.1Q VLAN Learning listbox is also set to enabled. For more
information about FastIP, see
“FastIP”
on
page 181
.
CAUTION:
If you change the setting of the FastIP listbox, the stack needs
to be reset before the change comes into effect.
802.1Q VLAN Learning
Enabled
/ Disabled
Allows you to specify whether the ports in the stack use IEEE 802.1Q
learning (GVRP) to place ports in VLANs automatically. For more
information about IEEE 802.1Q VLAN learning, see
“Using IEEE 802.1Q
Learning”
on
page 167
.
802.1p Multicast Learning
Enabled
/ Disabled
Allows you to specify whether the ports in the stack use IEEE 802.1p
multicast filtering (GMRP) to filter and forward multicasts automatically.
For more information about IEEE 802.1p multicast filtering, see
“IEEE
802.1p Multicast Filtering”
on
page 191
.
IGMP Multicast Learning
Enabled
/ Disabled
Allows you to specify whether the ports in the stack use IGMP multicast
filtering to filter and forward multicasts automatically. For more
information about IGMP multicast filtering, see
“IGMP Multicast
Filtering”
on
page 192
