MAC Address Aging Time 10 …1000000 sec, 205 | D-Link DES-3326

DES-3326 Layer 3 Fast Ethernet Switch User’s Guide

Figure 7-15. Switch Operation Mode window

Use the Restart Mode pull-down menu to select one of the two switch operation modes: Layer 2, Support IEEE 802.1Q VLANs and IP Routing, Support IEEE 802.1Q VLANs.

To make a change in the operation mode of the switch effective, click Apply.

The switch will then save the changes made during the current session and reboot. The switch must be rebooted to change the operation mode.

Menu Changes with Switch Operating Mode

Once the switch is configured for IP Routing (Layer 3 Switching), and rebooted, the Web Manager menu adds some functions compared to the Layer 2 Only mode.

Switch Settings

The Switch Settings menu allows for various functions − some of which are configured on different console screens − to be enabled or disabled on the switch (globally), without altering the individual function’s configuration. Thus, the Distance-Vector Multicast Protocol (DVMRP) is configured from the Configuration → Multicasting → IP Multicasting → DVMRP Settings window, but can be enabled or disabled from the Layer 3 IP Routing Protocol Settings window − without changing the DVMRP configuration entered in the DVMRP Settings window.

Layer 2 Switch Settings

To access the Layer 2 Switch Settings window, click Layer 2 Switch Settings (Configuration → Switch Settings).

Figure 7-16. Layer 2 Switch Settings window

The following fields can then be set:

ParameterDescription

MAC Address Aging Time (10 …1000000 sec)

Specifies the length of time a learned MAC Address will remain 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.

Broadcast/Multicas	This field can be toggled among Broadcast, Multicast, BCST
t Storm Mode	& MCST, and Disabled using the space bar. These options
