PD
MaxCurrent
(mA)
(PWR model
Only)

This field is only available on the PWR model but not available for the Gigabit and
mini-GBIC slots.
This field shows the maximum current a powered device can get from the Switch. If
the powered device’s power consumption exceeds the maximum power offered by the
Switch, the Switch stops sending power.
The Switch can provide up to 351.36mA current to one PD connected to each 10/
100Mbps Ethernet port and up to a total of 123.2W power to all PDs connected to the
Switch.

PD
MaxPower
(mW)
(PWR model
Only)

This field shows the maximum power the Switch can provide through this port.

LACP

This field shows if LACP is enabled on this port or not.

TxPkts

This field shows the number of transmitted frames on this port

RxPkts

This field shows the number of received frames on this port

Errors

This field shows the number of received errors on this port.

Tx KB/s

This field shows the number kilobytes per second transmitted on this port.

Rx KB/s

This field shows the number of kilobytes per second received on this port.

Up Time

This field shows the total amount of time the connection has been up.

Tx Packet
The following fields display detailed information about packets transmitted.

TX Packets

This field shows the number of good packets (unicast, multicast and broadcast)
transmitted.

Multicast

This field shows the number of good multicast packets transmitted.

Broadcast

This field shows the number of good broadcast packets transmitted.

Pause

This field shows the number of 802.3x Pause packets transmitted.

Rx Packet
The following fields display detailed information about packets received.

RX Packets

This field shows the number of good packets (unicast, multicast and broadcast)
received.

Multicast

This field shows the number of good multicast packets received.

Broadcast

This field shows the number of good broadcast packets received.

Pause

This field shows the number of 802.3x Pause packets received.

TX Collision

The following fields display information on collisions while transmitting.

Single

This is a count of successfully transmitted packets for which transmission is inhibited
by exactly one collision.

Multiple

This is a count of successfully transmitted packets for which transmission was
inhibited by more than one collision.

Excessive

This is a count of packets for which transmission failed due to excessive collisions.
Excessive collision is defined as the number of maximum collisions before the
retransmission count is reset.

Late

This is the number of times a late collision is detected, that is, after 512 bits of the
packets have already been transmitted.
