Configuring VLAN Routing
You can configure GS700TR 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.
IcmpOutErrors The number of ICMP messages which this entity did not send due to
problems discovered within ICMP such as a lack of buffers. This value
should not include errors discovered outside the ICMP layer such as
the inability of IP to route the resultant datagram. In some
implementations there may be no types of error which contribute to this
counter's value.
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 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.
