Configuring VLAN Routing

You can configure GS752TXS Smart Switch software with some ports supporting VLANs and

some supporting routing. You can also configure the software to allow traffic on a VLAN to be

treated as if the VLAN were a router port.

When a port is enabled for bridging (default) rather than routing, all normal bridge processing

is performed for an inbound packet, which is then associated with a VLAN. Its MAC

Destination Address (MAC DA) and VLAN ID are used to search the MAC address table. If

routing is enabled for the VLAN, and the MAC DA of an inbound unicast packet is that of the

internal bridge-router interface, the packet is routed. An inbound multicast packet is

forwarded to all ports in the VLAN, plus the internal bridge-router interface, if it was received

on a routed VLAN.

Since a port can be configured to belong to more than one VLAN, VLAN routing might be

enabled for all of the VLANs on the port, or for a subset. VLAN Routing can be used to allow

more than one physical port to reside on the same subnet. It could also be used when a

VLAN spans multiple physical networks, or when additional segmentation or security is

required. This section shows how to configure GS752TXS Smart Switch software to support

VLAN routing. A port can be either a VLAN port or a router port, but not both. However, a

VLAN port may be part of a VLAN that is itself a router port.

VLAN Routing Wizard

The VLAN Routing Wizard creates a VLAN, adds selected ports to the VLAN. The VLAN

Wizard gives the user the option to add the selected ports as a Link Aggregation (LAG). With

this wizard, you can:

• Create a VLAN and generate a unique name for VLAN.

IcmpOutSrcQuenchs The number of ICMP Source Quench messages sent.

IcmpOutRedirects The number of ICMP Redirect messages sent. For a host, this object is

always zero, since hosts do not send redirects.

IcmpOutEchos The number of ICMP Echo (request) messages sent.

IcmpOutEchoReps The number of ICMP Echo Reply messages sent.

IcmpOutTimestamps The number of ICMP Timestamp (request) messages.

IcmpOutTimestampReps The number of ICMP Timestamp Reply messages sent.

IcmpOutAddrMasks The number of ICMP Address Mask Request messages sent.

IcmpOutAddrMaskReps The number of ICMP Address Mask Reply messages sent.
