The port1 to port6 checkbox is disabled so that the user can always use port1 as a back door to access the

web config page when the port based VLAN is enabled.

•

802.1q Port VLAN Setting - Default VID Is used when 802.1q is enabled but input packet does not have a VLAN

tag. In this case, the Default VID will be used as the packet's VLAN tag.

Even if the input packet has a VLAN tag, user can still enabled the Force VID to change the VLAN tag of the

packet to the Default VID of the inport.

•

New VLAN ID - This is for adding new VLAN ID and the member tag into the VLAN table. VLAN ID can be any

integer between 1-4095. The maximum VLAN table size is 64. The member tag determine if a port is a

member of the VLAN and how to modify the packet when it exits the switch.

UnMod - This port is a member of this VLAN, packets will exit unmodified.

Drop - This port is not a member of this VLAN.

UnTag - This port is a member of this VLAN, packets will exit with the VLAN tag removed.

Tag - This port is a member of this VLAN, packets will exit this port with the VLAN tag. The VLAN tag can be

either the original one coming with the packet or the default VVID of the inport.

•

802.1q VLAN Table - This is the entire VLAN table. The user can select an entry and click

Delete VLAN Entry

to remove this VLAN ID from the table.

RMON Statistics

This screen is used to view the RMON counters for each port.

Port Selection - Select the port to display the packets statistics.

EtherStatsDropEvents - The total number of events in which packets were dropped by the probe due to lack of

resources. Note that this number is not necessarily the number of packets dropped; it is just the number of times

this condition has been detected.

EtherStatsOctets - The total number of octets(bytes) of data (including those in bad packets) received on the

network (excluding framing bits but including FCS octets). This object can be used as a reasonable estimate of

ethernet utilization.

EtherStatsPkts - The total number of packets (including bad packets, broadcast packets, and multicast packets)

received.

EtherStatsBroadcastPkts - The total number of good packets received that were directed to the broadcast

address. Note that this does not include multicast packets.

EtherStatsMulticastPkts - The total number of good packets received that were directed to a multicast address.

Note that this number does not include packets directed to the broadcast address.

EtherStatsCRCAlignErrors - The total number of packets received that had a length (excluding framing bits, but

including FCS octets) of between 64 and 1518 octets, inclusive, but but had either a bad Frame Check Sequence

(FCS) with an integral number of octets (FCS Error) or a bad FCS with a non-integral number of octets (Alignment

Error).

EtherStatsUndersizePkts - The total number of packets received that were less than 64 octets long (excluding

framing bits, but including FCS octets) and were otherwise well formed.

EtherStatsOversizePkts - The total number of packets received that were longer than 1518 octets (excluding

framing bits, but including FCS octets) and were otherwise well formed.

EtherStatsFragments -The total number of packets received that were less than 64 octets in length (excluding

framing bits but including FCS octets) and had either a bad Frame Check Sequence (FCS) with an integral number

of octets (FCS Error) or a bad FCS with a non-integral number of octets (Alignment Error). Note that it is entirely

normal for etherStatsFragments to increment. This is because it counts both runts (which are normal

occurrences due to collisions) and noise hits.

EtherStatsJabbers - The total number of packets received that were longer than 1518 octets (excluding framing

bits, but including FCS octets), and had either a bad Frame Check Sequence (FCS) with an integral number of

Octets (FCS Error) or a bad FCS with a non-integral number of octets (Alignment Error). Note that this definition of

jabber is different than the definition in IEEE-802.3 section 8.2.1.5 (10BASE5) and section 10.3.1.4 (10BASE2).

These documents define jabber as the condition where any packet exceeds 20 ms. The allowed range to detect

jabber is between 20 ms and 150 ms.

EtherStatsCollisions - The best estimate of the total number of collisions on this Ethernet segment. The value

returned will depend on the location of the RMON probe. Section 8.2.1.3 (10BASE-5) and section 10.3.1.3

(10BASE-2) of IEEE standard 802.3 states that a station must detect a collision, in the receive mode, if three or

more stations are transmitting simultaneously. A repeater port must detect a collision when two or more stations

are transmitting simultaneously. Thus a probe placed on a repeater port could record more collisions than a probe

connected to a station on the same segment would. Probe location plays a much smaller role when considering

10BASE-T. 14.2.1.4 (10BASE-T) of IEEE standard 802.3 defines a collision as the simultaneous presence of

signals on the DO and RD circuits (transmitting and receiving at the same time). A 10BASE-T station can only

detect collisions when it is transmitting. Thus probes placed on a station and a repeater, should report the same

number of collisions. Note also that an RMON probe inside a repeater should ideally report collisions between the

repeater and one or more other hosts (transmit collisions as defined by IEEE 802.3k) plus receiver collisions

observed on any coax segments to which the repeater is connected.

EtherStatsPkts64Octets - The total number of packets (including bad packets) received that were 64 octets in

length (excluding framing bits but including FCS octets).

EtherStatsPkts65to127Octets - The total number of packets (including bad packets) received that were between

65 and 127 octets in length inclusive (excluding framing bits but including FCS octets).

EtherStatsPkts128to255Octets - The total number of packets (including bad packets) received that were between

128 and 255 octets in length inclusive (excluding framing bits but including FCS octets).

EtherStatsPkts256to511Octets - The total number of packets (including bad packets) received that were between

256 and 511 octets in length inclusive (excluding framing bits but including FCS octets).

EtherStatsPkts512to1023Octets - The total number of packets (including bad packets) received that were

between 512 and 1023 octets in length inclusive (excluding framing bits but including FCS octets).

EtherStatsPkts1024to1518Octets - The total number of packets (including bad packets) received that were

between 1024 and 1518 octets in length inclusive (excluding framing bits but including FCS octets).

Port Mirroring

This screen shows the status of each port and allows you to configure the port mirroring settings for the manage

switch feature. The information here is for the wired LAN ports. For wireless status and packet counts, please

refer to the Wireless Status page.

Port Information Table

Ports 1 through 5 are the wired ports. Port 6 is the wireless port.

Link - If a port is connected, then the status is up, otherwise it is down.

Duplex - The auto-negotiation result of duplex mode, can be full duplex or half duplex. Full duplex mode will allow

packets sent in both way simutaneously and results in 2x througput than half duplex mode.

Speed - The auto-negotiation result of speed. It can be 10Mbps or 100Mbps.

Rx Packets - Received packets count

Tx Packets - Transmit packets count

Port Mirroring Setting

Port mirroring will duplicate traffic from the

From Port

to the

To Port

. This is good for debugging network

problems.

Type - Disable will turn off the monitor function.

Monitor egress

will only monitor traffic exiting the from that

specific port.

Monitor both

will monitor both directions of traffic in the From Port.

From Port - The port to be mirrored.

To Port - The port where the traffic is mirrored to.
