Configure VLAN Routing
You can configure the switch with some ports supporting VLANs and some supporting
routing. You can also configure the switch to allow traffic on a VLAN to be treated as if the
VLAN were a router port.
When a port is enabled for bridging (the 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.
Because 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 the switch to support VLAN routing.
From the Routing > VLAN menu, you can access pages that are described in the following
sections:
Use the VLAN Static Routing Wizard on page 164

IcmpOutDestUnreachs The number of ICMP destination unreachable messages sent.
IcmpOutTimeExcds The number of ICMP time exceeded messages sent.
IcmpOutParmProbs The number of ICMP parameter problem messages sent.
IcmpOutSrcQuenchs The number of ICMP source quench messages sent.
IcmpOutRedirects The number of ICMP redirect messages sent. For a host, this 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.
